Ok so I have an 86 22rte 4x4 truck. I overhauled the engine and sawped out the ct20 for the ct26 but the truck still smokes when it gets warm. The truck is straight piped could that have anything to do with it? The oil supply or return line has a small kink in it but still allows oil to pass through. I am at my wits end with this truck. Any advice as to what it could be?

is it smoke, or steam?

toda90

Its smoke and it smells like oil I don't under stand why it would be burning oil tho.

It's a fresh turbo on a fresh engine

justin_4runner

is it pulling oil in threw the pcv valve? see if u hear the ball bouncing around.

That or valve cover vent that vents back in right before the turbo. That seems to be common. Mine was sucking the oil out the valve cover,through the turbo,and blowing it into my intake manifold.

I'm sorry but I'm used to my Chevy 350 but where is the PVC on this Toyota motor. And the vent did have a leak in it right before the turbo

toda90

I want to say that the vent is my problem becouse there was some oil around the base of the vent. How would I fix that? Plug it?

pcv is on the valve cover near the back. it will have a medium size hose going to it.

Toda - any chance you have a spare turbo thermostat housing?

sorry to hijack.....

Sure don't man

I'm goin to put a bunch of pics and video in to one video and then post it to YouTube then y'all can see just how bad it's smokeing and how I have everything ran. I'll add another post with detalls on how to find the video later

Some people plug off the hole where it goes into the intake pluming before the turbo (so you don't have a vacuum leak) and put one of those little "k&n" style breathers on the valve cover part. I built a oil catch can to run between the two and it seemed to work. I also built one for my pcv valve too.

toda90

I plugged the hole and put a k&n type filter on the valve cover and it stopped the smokeing then I topped off the oil and guess what the smokeing is back. I'm starting to think I got a bad turbo.

I am so over working on this truck. Is there anything else it could be?

Turd Furgeson

It could still be a bad turbo,these ct 20's are known to be pieces of crap. I did the oil catch can and didn't have oil getting into the turbo anymore but.........I was still getting it oil in the intake manifold,so my turbos done.

toda90

But I put a ct26 on the truck the ct20 is gone. What's an oil catch can? And how do u make one

Turd Furgeson

Kinda hard to explain how to build one. You can buy them. I made one of mine out of my old trucks charcoal cannister,and the other one out of an old a/c receiver/drier. Basically it's a can that separates the blow-by gasses from the oil and leaves the oil in a can while the blow-by gets sucked back into the intake like it's supposed to. I put in petcocks (hehe,petcocks) in the bottom of the cans so I can easily drain whatever oil has made it into them.

I know the oil drain on my T3 has to be pointed straight down with absolutely no restriction. I'm running a 1/2" line from the drain straight to the oil pan with no restrictions at all. you could pull the exhaust housing off the turbo and see if the turbine is saturated in oil. If it is and you pull the manifold off the motor and look in at the exhaust ports and they seem to be dry, it's got to be the turbo. Mine uses a little bit of oil and when I pulled the manifold off, the valves had a little wetness on them from valve seals.

Yeah I found out That my oil return had two kinks in it. I ran a better shorter line with no kinks and boom no more smoke. Thanks guys my next step was to roll it off a cliff
