turbo smoking help
my friend has a shelby lancer with a 2.5 sohc block with a neon dohc cam head custom made everything. now he has a 1.10 rayjay turbo everytime he step on the gas it smoke blue smoke. the seals on the turbo was bad and he replace them. could it be that the oil is still in the housing of the turbo. he just got it together and it is not a everyday car. also there is not exhaust if that helps. thanks.

Re:turbo smoking help
there is no exhaust coming out the tail pipe?
sounds like a bad turbo... and the exhaust is leaking from it maybe... would be blue because its so rich and hot? |
Re:turbo smoking help
well there is no exhaust from the turbo no downpipe. he has no egt gauge no air fuel ratio. could it be because i running to rich. i hear the turbo spooling up. and also no o2 sensor. could my exhaust be a problem meaning runnig to rich.

Re:turbo smoking help
Put a valve on the oil supply line. The turbo is getting too much oil from the engine. Just open the valve very slightly until it allows a small amount of oil through. you can tell when the oil is flowing because the pipe will be warm. I have used this fix on a couple of turbos

very true. often over 60psi oil pressure can actually push the seals out. there is a good article in maximum boost about that. great post man! |
Re:turbo smoking help
that's why I always use the factory banjo fitting, or at the very least, close to that same size inlet.

Re:turbo smoking help
I have the stock banjo fitting for my oil supply line and it still smokes but only when i let off the gas and coast and then hit the gas again or if i am waiting at a light.

Or on some decal's smoke can come from Valve steam seals. Jeff |
