oil in turbo need help

[happyjonn]

so i had me turbo off to do some exhuast work. i had noticed a decrease in power and upon inspection found a crack in the pipe before the turbo. so i took it apart to weld and set the turbo on the ground with the oil lines still connected. when i came back a while later it was in a big puddle of oil.

is there an oil seal in there that has blown? maybe that is a second reason why my power was lacking?

its a garrett turbo the numbers i found on it are a/r 80 and m24
so if theere is a seal in there gone can someone suggest where to get one.

thanks

I think you ok , no oil seal, sounds like good old gravity took over.

so i got the crack in my exhaust welded but i am still not getting any power. it gets up to about 5 pounds of boost and then bogs down and kind of backfires???

What is your AFRS?

Does the turbo spin easily by hand or is it rough?
These turbo's oil drains are gravity feed and if you set it on the ground and the oil from the lines pooled in the bearing then weeped past the ring seals so that is what you found dripping.

the turbo spins smooth so turbo is fine i guess. when sled was working good my air fuel seemed to be mid 13s when idling or slow riding then goes up to normal 14.6 when really on the gas. now it seems to stay around that mid 13 range them when it starts to run crappy at mid throttle it goes all over the place. could it be something simple like a fowled plug? it seems to start, and idle fine just once it goes past half throttle and about 5lbs of boost then no power?

WOW that is/was way to leak do a leak down......

AFR's will also show lean if there is a misfire, because the air is just passing thru the cylinder unburned...

2X what Skydog said, do a cylinder leakdown. We'll start there.
