I pulled my intake manifold today because it’s leaking coolant. This is the 3rd time I have done this. Anyone have any tips for keeping the intake sealed? Also, any specific intake gasket that I should use? I have been using the TBI intake gaskets because you can buy them for cheaper because they don’t come in a set like the TPI gaskets do. Is this my problem?

Odyssey

Your problem is probably because you're not putting a thin bead of silicone around all four water ports of the gaskets, on BOTH sides of the gasket.

HEY Odyssey ive really got you now why dont you quit being a pile of **** and send my friend the intake he sent you $385 for back on oct 26th that you already cashed!!!!!! he bought it off of u on ebay now you have the same intake on the classifieds here
GUYS DO NOT DEAL WITH THIS GUY HES A CROOK im going after him the reason im so sure this is the same guy is i about bought the one here on thirdgen till he sent me his name and address and its the same as the one we sent the 385 to on ebay hes now barred on ebay his name is Edmond Indre here is the email he sent me jus 10 mins ago
Well the shipping comes out to 17 dollars for UPS ground service. I already have the box that John sent it to me in so that wont be a problem.
My name and address is Edmond Indre at 3428 Corona Del Mar, Las Vegas, NV 89108
heres the e,mail with his address after we won it on ebay How are ya ? My address is 3428 Corona Del Mar, Las Vegas, NV 89108 and my
>>name is Edmond Indre. The fuel lines cost me 80 dollars, but I'll oferr
>>them to you for 60. They're still brand new, never used, no fuel ever ran
>>through them. and heres the link to the ebay auction i won http://64.4.8.250/cgi-bin/linkrd?_la...m%3d1868977281
his other email is bluetide@TideFans.com his email now is z28@pclv.com any info from you guys to help us with him would be greatly apprecated we jus want our money back now

One of the e-mail addresses is wrong, Edmond Indre can be reached at z28@lvcm.com or doublemint@tidefans.com

Edmond, don't be a POS, send the intake to this guy and clear it up.

383LT1intake

thank you john i was going to contact you but you jus saved me the hassel i bought my lt1 right from you this ones for my friend do you have any now thanks

89 Iroc Z

Anyways..

Should I put thread sealent on the intake bolts?

383LT1intake

jus to be safe i put sealent on mine

8Mike9

Yes, put the liquid Teflon sealer on ALL the bolts. This will minimize coolant and oil from seeping up the threads.

Curious, are you still running stock fan on/off temps?

Morley

How did your friend pay for the auction? If he sent a check, money order or any other payment through the mail then go here https://www.usps.com/postalinspector...dComplaint.htm and file a mail fraud complaint against him. There are other sites for internet fraud, including one run by the FBI.

Morley

I bet it is leaking by #8 cylinder. Very carefully inspect the intake where it is leaking, look for any pitting or other signs of errosion. If you find signs of errosion, clean the intake with acetone and a wire brush (toothbrush sized) where it leaks, fill the area up with JB Weld and let it sit, when cured file it down smooth and even with the surrounding intake surfaces.
Also, when you torque the manifold down, go to the max torque called out (Chiltons lists 25-45 ft/lbs). Use Rol, or GM gaskets for TPI on it.

4L60bliss

I agree with morely, you may have a pitted coolant port. Look on the intake side of the coolant port at the rear (inspect the fronts too) for signs of pitting. Gaskets need a smooth flat surface to seal. I don't like using RTV on intake gaskets, but if the intake is pitted, I'll smear the RTV around the coolant port on the intake only to fill in the pits, then quickly torque the intake down as per service manual.

89 Iroc Z

It was pitted a few months ago (last time I took off the intake) so I used JB weld on it. It is perfectly smooth now and still leaking. Is there any trick when putting on the intake manifold to keep it from leaking?

Odyssey

Yes. Use RTV around the water ports ?

rezinn

Definitely use some sort of sealer on the intake bolts, and make sure you're using washers. The last couple times I didn't even put rtv around the ports and I've had no problems losing any coolant. If you're worrying about how well it will seal, I'd probably use it.

Morley

The only time I used RTV to try to seal the water jacket ports, I was removing the intake less than 6 months later for the same leak. The only thing I use is a little permatex hi-tack to hold the gaskets in place while I drop the manifold in place. Torque is VERY important, go to the high side and use the reccomended sequence and do it in stages.

scottydta

the TBI gaskets are different than the TPI. the TBI's have the rear coolant passeges blocked off, the TPI's are open. i bet the pressure from being blocked off is causing the gasket to blow out. either cut out the aluminum block off from the TBI gaskets or buy the TPI set

scottydta

top is TPI
bottom is TBI

4L60bliss

It shouldn't matter that he is using the gaskets w/ the blockoff plate, because TPI intakes don't have water crossovers in the rear anyway.

scottydta

yeah your right, they must be making 2 different sets of gaskets because it doesn't make a difference. try again.

DannyT

Do you have the stock heads and manifold?

Are you using the cork end gaskets that came with it or are you using silicone on the ends?

Can you isolate where it is leaking?

4L60bliss

OK numb-nuts, since you obviously know more about gaskets than anybody else , perhaps you would care to explain how a blockoff in the gasket is going to cause an overpressurization on a port that STOPS 9mm into the intake. Sounds like your really on the ball, keep up the good work.

89 Iroc Z

It was leaking in the front in on both sides

4L60bliss

Before you take it all apart, take a torque wrench and torque the intake bolts to see if they have backed off. I don't like using RTV on the gaskets themself, but if you have not been, this time put RTV around the coolant ports on both sides of the gasket. While the intake is off, look at the old gaskets and see if you can tell if they have been evenly compressed. You may have a warped manifold. Not many people have a true straightedge in there toolbox, but if you can get a hold of one (or have one) now would be the time to check the mating surfaces for flatness and pitting. (the pitting will be obvious without the straightedge).

And for the record, some TBI intakes have water crossovers in the rear like alot of the carbed intakes, and require the use of the block off plate, however, since the TPI intake does not have the crossover, they are not needed, however, having them will not effect operation since its redundant, but Scottydta already knew that

I like it on the tpi center 4 bolts; a little on all bolts can't hurt.

GMmuscleman

Every TBI gasket I've ever seen has the block-offs, and I've never seen a TPI gasket with blockoffs. I don't know that much about all the various gaskets, but it seems to me the easiest fix would be to use a TPI gasket to start with. There's got to be a reason they make different kinds and specific which to use with which type of intake. What that reason is, I don't know. But they wouldn't make two types if all motors used the same one would they?

4L60bliss

I knew you would show up sooner or later. Mr Autotech couldn't handle it so he went back to get his cronies to bail him out.

Your right, they do make TBI gaskets different than TPI gaskets for a reason. Just like they make different cylinder heads for different engines for a reason, but that didn't stop people from ditching them for some 186 or 492 castings. The point is, the Small Block Chevy is all about INTERCHANGE. If either one of you ever took a TPI lower intake off a car or even seen one, you'd see that the coolant ports go NO WHERE. THEY STOP. Its like a guy wearing a belt and suspenders. Is the belt really needed any more? No, but WTF is it hurting? Get a grip. The whole point to scotts original argument was that the plate was causing an overpressuriazation! What sense does that make. Would not the coolant port stopping cause an overpressurization????? Would not the air bleed hole so clearly pictured in the pictures scott posted not let the pressures "equalize" anyhow? Let it go.

Its really sad that a fellow who didn't even graduate Vo-tech comes on here, spoutin off about stuff he don't understand, and when corrected, gets pissed off and leaves a smart remark. Then when the offended party responds, he goes and cries to his buddies over at GMMOC to post here in his defense. That really says alot


WTF is next? Are you going to start preaching to everybody that they cannot use DEXIII in there auto because the dipstick says USE DEXII ONLY ???? LOL

irocbsa

:sillylol: Day-um!!!!

james_85Z28

rezinn

lol... The gasket doesn't matter because hardly any coolant goes behind there anyway. You might want to try a different type of gasket, though. Maybe you can find one that is thicker. I'm wondering if your manifold is warped or something, have you checked it for straightness and cracks in the front? Did you have it milled after you jb-welded it? Maybe it would be best to just get a new manifold.

vwdave

Thanks for the USPS link. I sent them a report on a guy who screwed me on a engine block.

Anyway.....

4L60bliss

89 Iroc Z, I'm really sorry you have to sift throug all the nonsense just to try and fix your car. Some people feel inclined to throw their 2¢ in whether they really know the subject matter or not.

In recap, double check the torque of the bolts to make sure they are not backing off, check the manifold for warpage or pitting, maybe try a different brand of gasket (I perfer Fel-Pro and ROL), use thread sealer on the bolts. I don't like using RTV on the gaskets themselves, but you may want to consider smearing a thin layer of RTV around the coolant port on both sides of the gasket. Also, I'm sure you have been, but just a reminder to torque the intake bolts to spec and in the proper sequence.


Good luck!

RacerXWS6

89 IROC Z Id listen to Bernard (4l60bliss). Hes a GM tech, and knows his ****. As for GMmuscleman.. well he doesnt know much as far as working knowledge would go. Scotty is good with a wrench, but Im not sure how in depth his knowledge is. BTW I know both of them.

GMmuscleman

I never claimed to be an expert. Sorry for not being an certified guru. And for the record, Scotty hasn't gone to tech school yet. So the part about him not finishing is false. Excuse me for posting. I thought this was an open board. I didn't realize you had to be a freakin' thirdgen genius to post. My bad. Now I remember why I don't bother with these boards anymore. It's not worth the bull****. And to think I've always talked about Mustang boys being the immature ones. Guess I need to rethink that philosophy.

Yeah RacerX, I know you to. And from your posts over on SEthirdgen, I see you're still bitter. That's fine. Whatever gets you through the day.

Lounge Lizard 6

It never entered our minds...

ctandc

If you're sure that you've been using the correct torque values on the bolts, tried thread sealer, filled any pits in the intake itself, then the next step is to check for straightness of the manifold, as has already been posted.

If it's a stock intake, if it were me, I'd simply try replacing it and see what happens. Replacement TPI intakes are pretty cheap. And besides...if that didn't work, you'd need to pull the heads and have them checked at that point....IMHO.


HTH and good luck

4L60bliss

Genius? No, nobody is expected to be a genius to post, but at least have an ounce of common sense.


Don't even go there, Matt. The person who you have come to defend is the one responsible for turning this thread into its downward spiral. Scott couldn't handle a different perspective on an intake gasket issue and had to be a pole-smoking smart-a$$ about it and it went downhill from there.

GMmuscleman

Let me guess, you've never even met Scott have you? Yet he's a pole-smoking smart-a$$. You just confirmed what I said above. No offense, but I think it's hilarious how people can thrash others on the internet when they really have no knowledge of the person or what they are like. And I'm sorry, but RacerX has a rocky past with Scott, so his views are somewhat biased because of past events. He didn't think Scott was a dummy when he was working on his Formula for him. I guess it's an easy way to try and gain respect and acceptance without having to actually talk to an actual face. I don't really care if I'm accepted on this board or all the others for that matter. I know who I am and who my friends are. It just irritates me to see a really cool guy get thrashed over a petty disagreement. It's way too kindergarten for me, but by all means continue if you feel the need. I wasn't trying to start any crap with my initial post. I honestly though that there were two types of gaskets for a reason. I see now that there really isn't a difference, so at least I got a little tid-bit of knowledge out of this. But if I'm labeled as a dumba$$ with no common sense because of it, that's fine. I'll probably never actually meet the majority of the people on here anyway, so no sweat off my back. Have a nice day.

Rumblin91

Your buddy made a smartass remark. Somebody corrected him, in no way disrespectfully, and he made a sarcastic remark. There was no need for that. He got thrashed, and deserved it. Especially since he didn't know what he was talking about. So stop being crybabies and get over it.

GMmuscleman

Not to be a crybaby, but if one little remark sparks the amount of thrashing that has happened, then I really don't think Scott was the one with the most disrespect. But, opinions are like a**holes, everybody's got them. Okay, I'm over it. Thanks for the input.

4L60bliss

Matt, your right, I have not met Scott, so my "pole smoker" comment was overboard, and for that, I'm sorry. But he is still a smart a$$. The original intent of my posting was to help a fellow out in need and help weed out some things thay may have not been his problem in a tactfull manner, but things couldn't be left well enough alone. All I can say is you reap what you sow.

RacerXWS6

Excuse me Matt, but Ive never said anything bad about Scotty, and as for mine and his past being rocky. Thats false. Scotty, and I have never had words regardless of what you think, or what he might have said. He sided with you, and Jason when things went down hill between all of us, and I havnt spoken to him since. Thats the bottomline of our past. As for me being bitter, no Im not. Never have been nor will I ever be. I made an attempt to be nice to everyone of you by posting on your board, and I got banned because Jason called some of your members names, and I defended what I was trying to do. Which I did without any name calling, or any BS. Its you who seem to be worried about me having any contact with those who went with you when our organization split. Bottomline... I geuss I dont care either way. Im happy things went the way they did. I was burned out, and not up to doing it any longer.

GMmuscleman

I guess calling Scotty a "jerk" wasn't something bad about him. Oh yeah, that was on SEthirdgen. Either way........

You see it your way, I'll see it mine. And let's leave it at that. I don't have the time or energy to argue this mute point anymore. As far as my board is concerned, maybe I overreached, maybe not. Either way, lurking on it after being banned once wasn't cool. To be honest Dre, I would love nothing more than for me and you to call it quits with the tension between us and just go on with life. However I really don't think posting on my board is such a good idea. Not because of me, but because there's quite a few people on there that aren't fond of you at all, one in particular being an admin, so the best thing is to not worry about joining my board and enjoy all the other boards you post on. Fair enough?

RacerXWS6

Its MOOT, and Im not worried about posting on your board. I was trying to do what you keep saying you want to do, and thats let it all go.

GMmuscleman

Works for me. I got your email. I'll reply sometime tonight. I've got some ideas I want to run by you about how we can reconcile all the crap between us the past year.

RacerXWS6

ok Ill be looking for it.

irocbsa

Hmmmmm....you find no problem with posting on a board that has 2 admins that aren't too happy with you. I think that it would also be a good idea if you would stay the hell off of SEThirdgen. Myself, and many others, didn't appreciate you attitude or your language. I don't condsider the the kind of crap that you chose to post on SE3GO to be too classy. It should be obvious since the post got locked almost immediately after you started posting. Let's make a deal, you keep your crap off of 4L60's board and I can almost guarantee that nobody from SE3GO will ever come near the site you run, which I've never even heard of BTW.

GMmuscleman

I apologize for what I posted on SEthirdgen. Me and RacerX are in the process of making amends, so give me a little while to take care of that. If it's alright, I plan to post on SEthirdgen and offer my apologies to everyone on there as well. Fair enough? Give me a second chance. I promise you won't be disappointed with what I have to say.

The site I run is fairly new by the way and doesn't have the membership of this or SE yet.

irocbsa

That's fair enough. The main reason I like SE3GO so much is that there has been an established precedent of respect and decency that you don't find very often on a lot of these type of boards. I, personally, would like to keep it that way. 4L60 has worked very hard to do just that. Personally, the man has given me a lot of respect and a lot of help. As always I welcome new members. Welcome to the community!

4L60bliss

Now doesn't that make you feel all warm and fuzzy inside:sillylol:

irocbsa

Screw you B.
