intern8tion9l Posted August 19, 2006 Report Posted August 19, 2006 yeah so heres the latest: when i let the car idle to warm up, it starts blowing out clouds of smoke. also when i downshift and i'm coasting in low gear/higher rpm (say an exit ramp) a cloud of smoke will start puffing out. this thing is really starting to get to me and its like every time there is something new its something wierd that i don't know about Quote
mfewtrail Posted August 20, 2006 Report Posted August 20, 2006 It's most likely a turbocharger oil seal leaking(bluish colored smoke). If you find oil in your intercooler charge pipes, the cold side/compressor seal is leaking, if the pipes are clean, it's going to be a turbine side seal. Check the TGP section and/or the TGP board, there have been a lot of topics like this in the past. Quote
intern8tion9l Posted August 20, 2006 Author Report Posted August 20, 2006 19cutlass94 also suggested i might be losing a cylinder due to a bad spark plug....the smoke is white and does have kind of a nasty fuel smell to it. i am running ngk iridium plugs, of which i have heard some bad reviews.....

Crazy K Posted August 20, 2006 Report Posted August 20, 2006 change your plugs do an oil change (oil might be contaminated with fuel) and report back! Quote
intern8tion9l Posted August 20, 2006 Author Report Posted August 20, 2006 will do. she's due for an oil change anyway Quote
R Dubya Posted August 20, 2006 Report Posted August 20, 2006 AC Delco R42LTS plugs. gapped at .040" Quote
intern8tion9l Posted August 20, 2006 Author Report Posted August 20, 2006 well looks like we have a winner. one of the plugs is dicolored, wet, and smells pretty nasty. of course its one in the back.....but anyway, is it ok for me to change just one, or should i change them all? Quote
19Cutlass94 Posted August 20, 2006 Report Posted August 20, 2006 You could probably get away with changing one, but really just change them all. Quote
R Dubya Posted August 20, 2006 Report Posted August 20, 2006 do them all and get away from those "higher performance" plugs. The AC Delco R42LTS is what is meant to be in these cars, I have never fouled one when there wasn't a bad coil, ICM, or injector. Speaking of which, have you determined what caused the fouling? Quote
19Cutlass94 Posted August 21, 2006 Report Posted August 21, 2006 It was probably because the iridium just got ate up. Quote
intern8tion9l Posted August 21, 2006 Author Report Posted August 21, 2006 well i will go with the delcos. too bad the store was closed today. i wish this were the only problem with the car Quote
R Dubya Posted August 21, 2006 Report Posted August 21, 2006 was it only one plug? do you have a bad coil? Quote
mfewtrail Posted August 21, 2006 Report Posted August 21, 2006 I've also never had a plug foul w/o having other issues. If the new plug you swap in gets fouled again, I would start looking at the injector on that cylinder(remove the fuel rail/injectors from the intake manifold and then check for leaks while the rail is pressurized). I recently replaced three injectors in my TGP, they were leaking pretty bad(it's very common for the early multec style injectors to fail). My car smoked at startup w/ the leaky injectors for what it's worth. Quote
Mach 5 Posted August 21, 2006 Report Posted August 21, 2006 Since the car is burning a white smoke, you could have a coolant leak. Id do a compression test on all the cylinders and compare your results. The fuel smell could be the injector or a leaky valve or gasket. Quote
