Kit installed. Now there's blue smoke out the exhaust

Drac9 · 07-01-2002, 08:12 PM

I finally got the kit installed on sunday. My problem now is that when I first start driving in the morning I start the car and drive about a block, not in boost. It then begins for blow blue smoke out the exhaust. It's blowing out pretty bad, almost looks like the rings are blown. After about 3-4 Miles it quits. Here's what I think is going on. I have a 90 degree -8 AN fitting coming right of the turbo to the drain tube. Then the drain tube does not go downhill the whole time, it has a bend up at the end to fit to the oil pan bung. I got no instructions with my kit and I didn't realize that the oil return line is not at all pressurized. I think the oil is pooling in there when the car has been sitting and then burning off when I first start driving? Does this sound reasonable? Any other ideas?

Turbo oil drains are gravity dependant.

You shouldn't have any 90's (or horizontal sections) and absolutly NO UPWARD FLOWING SECTIONS!!! The oil will not flow out of the turbo fast enough and this will cause the oil to heat up too much, and if for some reason your not running synth. oil (takeing a brick to the head may cause that!) the extreem heat will break to oil down into a few worthless liquids and gasses. And if the decreesed drainage is bad enough, the oil may be presurized past the seals were it will be burnt (blue smoke).

I hope you ability to fabricate is better than my spelling!! You need to fix this ASAP! Or you may be looking for a new turbo too.

Keep in mind this is all a worst case rant, (short of conecting the wrong fittings to the wrong places?) You said you got no instructions! The turbo should be mounted so that the oil drain is on the very bottom, pointing as straight down as possable.

post pic's if you can, good luck!!

Hello there:
Just a note since there isn't any other info. In my case I plugged the head valve cover vents and that caused a lot of blue smoke out of my car. Unplugged them and problem fixed. Just in case ...

maybe you're getting too much pressure in the crankcase and oil is being forced out causing blow by. get an oil catch can/crankcase vent and it should be better.

Drac9 · 07-01-2002, 10:26 PM

I have the crankcase vent hoses just laying in there right now. They are not T'd yet into the catchcan. Could that be causing it?

it's not the crankcase vents it's what HYDCSX400 said, that that return line all flowing downhill, you should be able to take the fitting off of one end, and cut the line a little bit then put the fitting back on, so it is the correct length. it'll make sense once the AN fitting is off how it all goes together, just remember, only cut a little bit at a time, as cutting it too short will require a whole new line. and they aren't the cheapest out there.

Make sure your crankcase vent hoses are not T'd into each other. TRI did that to my system when I got the car back and blew serious oil thru the turbo. The vent hoses should be routed into the intake.

Definitely oil back up from the rise in the drain line would cause oil pasing the seals too.

well you can T them you just have to do it right... i had it going to my intake but i didn't want oil going into the intake so i put a filter on my oil catch can and had everything go to my can and plugged up the pcv....
