Oil from...?

[darkfa8]

I was going over the engine bay today and noticed my gasket for my plenum/plenum spacer is leaking and there is oil residue spread out on the intake side of the plenum casting...

My pt54 turbo was rebuilt by Mease in mid-October 2002 with new turbine wheel shaft assembly (John Craig), 360 Dynamic Thrust Kit (John Craig), Piston Ring (John Craig) and Dynamic seal (Robert Blouch Turbo).

the te44 I had on previous blew a little bit of oil...

Could the intercooler be to blame for maybe holding some oil? Or should I seriously suspect the turbo?

I've had the plenum off before since having this turbo on it, and there was a noticeable oil sheen and droplets on the plenum. Even after a few days of running Mease's proto-type aluminum-sheetmetal plenum and taking that off, there was a noticeable oil sheen/drips on that too.

Any suggestions?

oil

take the intercooler off and flush it with 2 cans brake clean, or 2+2, swish intercooler side to side and dump residue, let intercooler sit in a heated place (by your heater or radiator) and let the cleaner evaporate, 3) get yelled at cause the house smells like Berkibile

In the PT54 is a "dynamic" style seal, this type of end seal WILL LEAK slightly because of their design nature....in other words they are not a positive contact seal such as the older "carbon" seals....high oil pressure (due to cold weather) will also blow oil through the seal....in the cold weather I run 5W30 Mobil 1.

You got a pcv valve? If so, check the line and see if it has oil in it-tho it sounds like a bit much for that.

I have a PCV, and have a new hose on that.

I have frequently been running in excess of 99psi in the cold weather with Sythetic blend. I've been running 10w-40. Hot idle oil pressure at 750-800rpm is 22-26psi, cruising at 60mph pressure is between 57-61 psi.

I will flush the intercooler as soon as i get a chance just for peice of mind and because i'm anal like that lol
