White smoke at start
Hi Guys
I've this embarrassing and annoying problem. When I start the car, just at the start, it makes this big white cloud of smoke. You can see it in this video of me (normally it's bigger):
[audio badly synced]
It's embarrassing because if I start the car near some people or next to a bar/pub/club, sometime the big cloud goes toward people. Super ugly.
Does anybody know what I can be? They say to me the valve seals, that causes oil leak inside the cilinder. Other opinions?
THANKS

Re: White smoke at start
Mine has the exact same issue when it's warm. How easy are these valve seals to replace?
Also what oil do you guys recommend I use on the car?

Re: White smoke at start
Hold on a second... If its smoking on startup when its warm, say 1/2 hour after you shut down and then go to start it and it smokes white...we're talking about a fuel thing. Fuel leaking into intake flooding the cylinders or injector leaking by.
Smoke on startup in morning, bluish gray/white is valve seals
There is a procedure on here how to do the seals with the heads on the car. There is 2 methods...1 is using a rope in the spark plug hole and 2 using compressed air from a compressor holding the valves up.
Both ways are pretty straight forward to do but also time consuming, but a knowledgeable person can do it on a Saturday.
Injectors are a piece of cake to replace. ForTPI remove runners and plenum and change em out. TBI R&R the 2 injectors in the carb.
Either problem needs to be verified before jumping to conclusions.

So would I need to replace my valve seals?

Re: White smoke at start
Mine does not smoke on cold start but upon warm starting after sitting for a couple of hours it will smoke blue briefly. If I warm restart with less than a couple of hours of sitting no smoke at all. I was told my issue was valve seals as the seals are allowing oil to drain into the combustion area. The car never smokes while running after the initial start up.

Re: White smoke at start
Gaspeddler...GM replaced my seals at 15k miles for that issue. Also changed out the intake due to center bolts gouging the holes...some kind of recall IIRC. Then years later, I had the hot soak smoke after running the car and letting it sit for an hour or so. Injectors were leaking into the cylinders causing the smoke.
Just some info for ya. Knowing you have a extremely low mile IROC.

Thanks Bob, I need to address this issue soon. Nothing worse than starting up my car following a car show and smoking up the place.

Re: White smoke at start
I drove mine today and on cold startup there is white smoke/steam coming out of the back and it doesn't smell of oil.
However when I got to work and turned it off and got out, there was a distinctive smell of oil around. I've had it checked and there was some oil that had been splattered around the engine bay. It also stalled on me whilst I was in traffic, it fired back up straight away but I've never had it do that before.
