Is my turbo bad
So I have a 91 crx hf, sohc zc vtec swap, hf main SR20det t25 turbo, OBD1 Uber 450s, ss oil line from home Depot. Anyways I did a few test runs using bbka map so I pull in to my drive way and notice oil on the floor. I check it out it was my return line had came lose, so I fix it then I want out for another run and notice it was smoking. I did a compression test and its 125 across the board. So im guessing it might be the turbo because there is oil in the down pipe, or i might need a oil restricker.

Re: Is my turbo bad
yeah 120 is ok for my motor but not for yours. put a teaspoon of oil in there and it will show you what it should be. also pressure from the oil feed line might have pushed pass the seal or just left a little in there. go dirve it around a bit more to see if it goes away<my guess.

Re: Is my turbo bad
My vitara block has 125 across the board 
I say run it into the ground. Smoking problems from turbo include 1. Blowby (get a cathcan) 2. Not enough gravity for oil drain (get more gravity) 3. Too big of an oil feed (run a restrictor or a 3AN line) 4. Turbo seals, smokes on decel and idle (rebuild or get a new one) off the top of my head those are the most common problems, if its not the turbo then I say get a catchcan and then run it into the ground.
