I have an oil burning issue which is not there with my old TE-60-1 journal bearing turbo. Since I had 2 of these turbo's I had one retro fitted with a brand new Garrett ball bearing center section cartridge, and p-trim wheel. The car pulls like a freight train, the spool is instantaneous, 0-22 psi in about second on the t-brake.
The issue I have is blue smoke out the exhaust, I removed the turbo, brought it back to my source, sure enough there was oil making it's way past the seal into the exhaust side, not much but it was wet ( I know a little oil can make a lot of smoke). What he did find is that the housing bolts were pretty loose too (my fault), no blade contact etc.... no thrust or lateral shaft play.
Being the great guy he is, he cracked open a brand new turbo, I saw it with my own eyes, both wheels, cartridge etc.....all new, he installed the guts in my turbo using only the housings, The turbo was clocked properly, all bolts torqued to spec, no shaft play, lateral or thrust.....
Fast forward, I put this unit on the car and I still have a lot of exhaust smoke!!!! I have eliminated the pcv, rings, oil in the intake (as sources of oil) the plugs are clean. I looked in the bell (exhaust side) and I see oil in there again. I confirmed there is an oil feed restrictor in the feed line, my oil pressure at idle cold is 60 psi, hot it goes to 20 psi, and the up about 10 psi per 1,000 rpm. There was so little oil on the cartridge that was replaced, that I doubt I have residual oil in the exhaust, I drove the car about 15 minutes and I still get smoke, mostly at idle or if I rev it a bit once the car is warmed up.
Anyone else having issues with this BB turbo cartridge or similar, did I get a another dud? Any suggestions please, I need to get it sorted out, I'm considering going back to a journal bearing. Do I keep driving it and see if it clears up?
