I am glad your car is running normal now. Take this lesson and learn from it. You have now worked on your car and understand it a little bit mroe now. A little learning and a little help is all it takes to get some problems fixed.

I myself gotta do some searching regarding previous topics here .... my car still runs a bit so so hmmm when it's cooler outside .... but once it's warm... runs better than I bought it *lol*.. I think the IAC may need to be replaced not just cleaned and adjusted .... oh well

Psycho91Camaro: This thread reads like a soap opera. Very interesting stuff. Shifty Capone knows his stuff. I am glad you decided to listen to him and not buy all new stuff.
Here are somethings I learned since owning 3 Camaros for 10 plus years.
1. If I don't know I just ask those that know.
2. Then I get a second and third opinion.
3. If all of the opinions match then I proceed. That should of been the case here. TGO is the best site in the world for our cars and most of the opinions are well intentioned and usually correct, or at least close. Plus they are free.
4. Sometimes I go to the junk yard and practice parts removal on the cars there. If all goes well then I do it on my car. Only cost $2.00 to do this. I followed this procedure when looking for a new intake manifold after a bolt would not drill out in my old thermo housing in the intake. It took 30 minutes to remove so when the dealership tried to charge me 5.3 hours times $100.00 to remove and install the intake I knew I didn't want them to do the work. And my original GM intake only cost me $20.00 this way. I did all of the cleaning and painting my self. Looks great, runs great and I feel great and so does my pocket. And I am not a mechanic by any means.
5. Pro shops and mechanics have to be checked up on as they often markup prices on labor or parts and often don't complete the work properly. It is their job to sell new and it is also easier for them to just replace with new than to rebuild. That's why they really charge you to rebuild anything. And many times you can do the same replacement or repair yourself. But if you take it to a shop then monitor your bill so you don't get ripped off.
6. It is much better to learn how to do the work yourself. At the very least understand what someone is trying to do to your car. You will feel much better when you do the work (if you can) and save money at the same time.
7. Don't fix too many things at the same time. i.e. remove the AC and install headers while still trying to solve overheating and oil leak problems. On these cars one step at a time is usually the best way.
8. Our cars will overheat at the drop of a hat. Your fan being on all of the time may of been wired that way by the previous owner. Some wire the fan hot wire(red/black wire coming directly out of fan if electric) directly to the fuse box while others tap into the green/white wire coming from the relay and ground it to the body of the car. I suggest you learn everything about your cooling system and how it works. My experience has been once these go haywire, everything else starts to act crazy.
9. Buy a good tool set. Don't get knucle buster sets-200 pieces for $20.00. Get real tools. It only cost a few more dollars to go first class. Everytime I have had a problem with a part or bolt it was usually because I did not have the proper tool. Really that is the difference in a good mechanic (besides knowledge) and a bad one. The one with the proper tools has an advantage over the shade tree who is too cheap or lazy to buy what he needs to do the job right.
10. Don't be afraid to put your car in the Chevy dealership for something you just plain can't do. However have a good understanding of what you want done and how much time it takes to do it and what it should cost. After all they built the car so they should be able to repair it.
P. S.: How did you get 405 post AND on Probation since just Feb.? Both have to be some kinda record. Did they say when the probation ends? I have seen guys on Probation for years around here.
Good Luck with your car.

You really paid 104 dollars for a stock manifold? What was wrong with the old one? Dirty?
Lets recap what you have done to your car sofar....
1. Replaced TB with used one. One on car was in need of rebuilding. Rebuilt the used E-Bay one. So had to rebuild a TB anyways so money on new TB= waste.
2. Replaced Intake Manifold. Oil seeping out gaskets. Bought another Manifold(stock) to replace old(stock). Didn't need new one old one was fine. New Manifold=Waste of money.
3. Paid a mechanic to do the swaping cause you didn't have time/desire to learn to do the swap of stuff after asking for help. No preblem there time is root fo all evil for alot of us. Though as result of you taking your car for this repair, you had to make time(claimed didn't have) to do numerous things that should of been taken care of during the repair. Like Set the timing, correct the firiing order(wich could of been there fault), Remove tape used to plug vaccum lines,ETC.... Now tracking down and Repairing things is quite time consuming. Especially since these things are something you shouldn't of had to do. After all you DIDN'T HAVE THE TIME!$341 to mechanic and you going behind him to fix his Hacks/Mistake=Waste of money. Good thing you probably get to deliver parts to his shop and smile knowing he bent you over. One good thing about his shop is he more then likley carries grease. Rofl
4. You knew you had an overheating problem yet never looked into Seeing what the problem was. After Asking for help here did you even buy a CTSensor or at least see why it was working improperly before you took it X miles away from home? It resulting in you for a bad evening.
Engine damage could of resulted like blown Headgasket or even a crack in heads or block. Driving it home and letting it heat up like it did is very bad for your motor. Especially since every time you heated it up less cooliant was there to cool the motor creating air pockets. Repairs for this could/still wind up in the $100's of dollars due to your lack of fixing a problem that you KNEW exsisted. Before you continual to drive the car I would look into why the wire burned up. They don't burn up for no reason.
5. You work at parts store(pepboys) and claimed they didn't carry intake gaskets and whatnot. Yet Stuff you needed is basic replacement parts found at Every Parts store in America. Unless they were sold out Cause there is like Thousands of Cars that used them. If that was case could had one of those shop you deliver to find them. HEHE. But to not Carry?
You must have an easy job dropping off parts to all these parts you don't carry at there shops since you have limited stock at pepboys. Even if part store don't carry a product they have this neat Idea you might know as SPECIAL ORDER! Hell I just went to there ONLINE SITE and seen all you needed was there.
Here's a thought. Next time you bored(how you found your job) go to any other parts store and ask them why you couldn't find your parts at Pepboys where you work.
6. You expected car to run right, yet never changed out plugs and such that you asked about until you decided it was the last thing you needed to do to get your car running right. This seemed like you was going to leave out of your repairs. Was $$ a problem cause I know plenty of places you could saved $$ from to pay for it or was you just hoping some things causing problems would disapear like MAGIC?
7. Glad you finally used the Feature Though doing so prior to checking what landed you on side of road over-heated would of saved alot of Posting for you and others here.
8. Make sure your motor is running correctly before you start buying stuff like that pretty blue hose covering and such. You overheating(knowing there was a problem) could of caused quite a mess in the engine bay making all that ugly potentially wasting $$. Like was said here in this thread before FIX what is wrong first then do all the goodies.
9. You driving your car X miles away from home knowing you Still have a problem with it STARTING? Did you plan on leaving it running while you took a stroll on the beach with your girfriend or this another repair you didn't have $$ for?
Sure would of sucked if you went for walk, got back to car and turn the key and nothing. While changing your sparkplugs having the pass-side of car jacked up you could of took extra 15 mins and swapped out the starter. This might be a wild guess but did you see if pepboys carried your part? HEHE
10. Listen to what people here are trying to HELP you with. If they say there isn't a short cut, to buy tools and auch they more then likley correct. Did you buy your Hanyes or Chiltons manual yet? If not go to parts store and buy one. Though you should shop at some other parts store but one you work at cause they might not carry it and a waste of your time

Some of that ^ is true I admit... but some isnt.
Anyways yes PepBoys carries my starter and alternator. Which I am going to purchase soon. The car doesnt overheat now it stays between 120 and 200

It smoked from my house to work and when I got to work I bought Lucas oil stabilizer it stopped the smoke while I was driving but when I drive. I stop at a red light (no smoke) then the light turns green and then I step on the gas (no smoke) then after 4 seconds of stepping on the gas I see a cloud of blue smoke!! dammn whats going on? is it time for me to save up for a crate engine? and sell those new parts I just got for my 305 to you guys to help fund me new 350 crate!???

Constant blue smoke is an indication of oil burning in the combustion chamber. Most likely very worn rings or leaky valve guides.

IF !!!
IF ... you indeed need a new engine .. IF (!!!!) ... those parts can be used on a 350 as well ... same intake .. same TBI (may need bigger injectors) .... will need tuning though
No offense guys ... to ya'll ... but the more I see and read (including in books about tuning Camaro's) "throw away 305 and get a 350 .. hell get a 383.. heck ... 396 ... to hell with that ... 454" .. *lol* ... the more I want to keep my 305
Just fix it ... the money you'll spend on the another engine, and other parts to get it running right in your car ... you can use to replace al lyour worn steering linkage .. and suspension parts ... coz trust me.. those parts ARE worn by now
That's my opinion *shrugs*
Still tweaking a little bit here and there myself to get my engine running right .. but it's getting better and better

Yep! I want a 383 because I want a 383. I don't need any more power than that especially with my desire for twin turbo. Get what YOU want. Gas prices will also be a bit better on the 305 and you can rebuild it on the low if you shop around even a little bit.

I would think more Valve guides Causing you your smoke. Them going bad is common. Do a and you will see it pop up on almost all the forums. It might be the start of the aftermath of you overheating your motor and way you got it home that night from the beach. So I wouldn't rule out the rings. Other problems might be sleeping waiting to awake also. Only time will tell. If its only valve guides you can drive on it for long time. I am 100% sure you need to replace your valve guides. Now would be a good time to try a compression test.
If you going to be saving up for new motor and keep the TBI you might want to find the time to LEARN some stuff or it will cost you lots of $$ to pay for stuff like chip burning and the swap. Thought if you were over your head with just swapping the intake and TB. You will be way over your head with this type of swap. This is where that $341 you paid the mechanic not to long ago would of paid off to of spent on tools.
Mail order chips will seem good to you,but you won't see the potential of your motor. Every motor reacts differently. Therefore need its own custom chip.
Sell what parts? The stock intake and TB that anyone who needs one can pick up at there local JUNKYARD?

tbi and intake
TBI junkyard 20 bucks
TBI rebuild kit 28 bucks
TBI manifold stock .. what.. 20 .. 30 bucks ?
*shrugs*
Psycho .. learn about the engine ...
I'm still learning myself ... but learning it well ... had to replace intake manifold gasdket and set timing ... ran into big problems... happened to be the wire/connector for the IAC
One of the reasons I bought the 305 TBI was.. I wanted to be able to fix the problems myself .... otherwise ... hey why not getting some Japanese car .. great on gas mileage.. however.. one can not fix anything without taking it to a damn computer to run full diagnostics
