FP Red Leaking Oil, Exhaust Clamp

1505 Views 5 Replies 2 Participants Last post by  sexyyrex
I have a FP Red that appears to be leaking as overspill from the center cartridge. I cant figure out for the life of me what's going on but its annoying as hell. Oil appears to be seeping from the clamp that holds the hot side housing to the center section.

Every time I park I have multiple spots of oil under neath the car from what appears to be oil dripping on the K frame, and being dispeared onto the ground that way. Some small sparatic whips of smoke can also be seen upon immediate inspection from turbo side of the motor.

The K frame is wet with oil, and car only seems to leak oil after being in boost after a drive. Engine has 350 miles on it from Maxwell Power Services. Turbo was a fresh rebuild when the motor first went in. Also, car has a crawford AOS, routed correctly.

Possible issues:
Oil Pressure Excessive
Crankcase Pressure Excessive
Oil Return Line Kink
Bad Turbo Rebuild
Bad oil return gasket (unlikey as this is just a drip line, no pressure)

Forced Performance Turbochargers

I talked to FP First:
They basically said there is no way its the "seals" unless I have crazy shaft play, well as of 350 miles ago, it was a fresh rebuild. They suggested my crankcase pressure is too high, I double checked and re-routed my AOS tonight, and all is well. They said turbo doesn't need a restrictor as its journal bearing and to over pressurize the turbo i'd need 80 psi of oil pressure at idle and 120 psi of pressure during operation. They suggested I check drain line for kinks, no kinks. They had also suggested due to it being a new motor that excessive crankcase pressure is likely.

I then talked to Maxwell:
They seem to think oil pressure is too high and that the turbo needs a restrictor. FP says no, no restrictor needed due to nature of the TD06 center section. They also suggested to check drain line, and AOS routing. Maxwell suggests upon proper break-in that excessive crankcase pressure should not be an issue. Maxwell also mentioned that the motors built usually have 40 psi oil pressure around idle and about 105 around operation. WAY out of FP's upper limit.

I talked to crawford:
They seem to think that I had possible kink in AOS plumbing somewhere. Double checked tonight, was found that this is not the issue.

Does anyone have any idea's as right now im pretty much out of ideas. I didnt think it could be anything more then what was listed and I SERIOUSLY don't feel like changing turbo's. I'd love for this to work. Just wanted to figure it out.

Sounds like you got a brand new motor but I cannot determine if the turbo is also new to you. Is this the turbo you where using before the new motor or is it a new motor and turbo?

Turbo was purchased while the motor was being put together. I purchased this turbo from another member and that was completely rebuilt by FP by the other member.
With a brand new motor and new tubo makes it really tough to determine. I would lean more towards what crawford and Maxwell said, To much oil getting to the turbo. Does it leak more at higher rpm's? If that is the case, then to much oil getting to turbo. If not then I would check and see if possibly the rebuild of the tubo is the issue.

i think maybe its too much oil. car doesnt smoke from exhaust at all though. only under hood. i dont get it.
