Mk1 gt tubby
Fresh Recruit
Hi all,
I have a starlet gt running the following mods.
FMIC, decat, aftermarket exhaust manifold, HKS actuator, powerflow exhaust. running airfilter in stock position, HKS SSQV.
Problem is i've noticed oil coming out of the compressor side of the turbo where the intercooler hot pipe connects. Also abit of oil in air inlet tract which has been blanked off from the re circ valve which rules out any oil coming in from rocker cover breather. No smoke coming from the exhaust at all? this probably rules out the turbo oil seal on the exhaust side. What would cause the oil seal on the compressor side to go? my turbo failed last time but was the exhaust side seal which was leaking into the de-cat causing blue smoke but no oil from compressor side at all. I have a catch can but the PCV is still in place, fitted to the other breather to stop oil mist going on the rocker cover. checked the pipe to the catch can and there is very slight oil mist in there so the engine isnt breathing heavy. sorry for the long post but need to find the root cause before i replace turbo.
Thanks
