So I'm posting this for a buddy of mine. He's got a 99 PSD, he straight pipe it, did a big filter and then got a tuner for it. I believe it's a super hips flashPac. Well while he was investigating his leaky oil pan he noticed the rear main seal on its way out.

The truck never dripped all that much oil, now he has to keep up with it, high crankcase pressure from the programmer?? Or just a coincidence?

 

is he sure it's the rear main? really check cos it might be turbo pedistol o rings.

 

I'll relay the message

 

Look in the valley of the motor... Oil will leak from anywhere in there and run down the back of the motor looking like the rear main...

 

Thats what it appears, theres oil higher than th seal. Will be doing further investigation!

 

Yea I just fixed a leaky hpop line that was seeping into the vally now she's runnin a lil smoother

 

I've had to do HPOP o-rings due to some bad leaks, and the whole time I was thinking rear seal. Now that my pan is leaking, I'll more than likely just do it while the engine is out.

 

hpop?

 

HPOP is high pressure oil pump. The o-rings and hoses are a source of most of the oil leaks that at first look like a rear seal.
