Well my car smokes quite a bit, only when it's warming up. Pours smoke everywhere, if I bring the idle up to around 3k it stops smoking. I'm thinking turbo seals.







Thanks

if it only smokes on warm up id tend to suspect the engine. is there oil on the spark plugs?

could also be the turbo though... only because at startup with the oil cooler thermostat closed, fuel pressure tend to skyrocket, and if you have weak seals on the turbos(or the engine also) your car will smoke a lot...



i agree with the previous post though, about the sparkplugs, easy enough to check

Most likely the Oil Control Rings.

i meant oil pressure .... not fuel pressure



im hesitant to say oil control rings because, i had the same problem with my FD (assuming its the same problem) and before and after rebuild it was the same thing, and after another rebuild it was the same. smoke would come out of the exhaust the first 5-10 mins then it would slowly go away as the oil pressure goes down, so thats 2 sets of new oil control rings

It's not on warn up, well it could be because I have to hold the idle at like 2500 to get it to run, damn tb mod. Also it's fine till I start to sit in traffic, then it smokes, I'll check the plugs after I let it cool down some.

Well here are the pic, the intake side is clean, and dry no oil, so I think that would rule out the turbo.... maybe i'm running too much premix? I donno, i'm using a 10:1 ratio.







The plugs are basically bone dry.
