still leaks!

[kylev90]

Just got my motor back in the truck from doing rear main seal, resealing the oil pan and doing rod and main bearings. Runs great but still leaking oil! Im ready to scrap the damn thing. Is there another common area for these to leak oil? Im thinking it might be coming from higher up on the motor. It is running directly down from somewhere around the top of the bell housing. Any ideas?

Does it have a puddle of oil in the valley? If not possible the plugs on the heads? JJ

[kylev90]

no oil in the valley. I was thinking about them plugs too. I just bought the UV dye to run in the motor in the morning so hopefully it will show up. Ill definitly check those plugs. Thanks Hardline

i have a 95 psd its oil cooler got to leaking real bad. it has 2 big o rings that get hard at
quit sealing. if i remember it is on the drivers side of the engine. may not be the problem
but you might check it. i had to take to the mechanic and he found it.

ok thanks miked ill definitly take a look. Im thinking it could be an o-ring in the turbo too. It just started giving me more of a motor shake. I can feel it in the cab bouncing me at an idle. Clears up when given some throttle. Make sense if its the turbo? Running rich due to lack of oil being circulated to turbo?

a leaky Turbo is not going to make the motor run rich.You probably have a loose UVH from pulling the motor.If the oil isn't pissing on the ground it is the drain not the feed so your turbo is getting plenty of oil.

FYI you don't need to pull the motor to do the Rear main.99% of all oil leaks are turbo orings or in the valley would be HPOP lines.The rear mains seal in these motors never ever leak and if they do it is a slight slight weep.

ya I didnt pull the motor for the rear main. My oil pan was trashed and needed replaced. So if it is the turbo its the drain. Thanks for the info. I just bought some of the UV dye so I am going to run it through today on my way home from work and take a good look at it.

Yeah, I'd definitley check the turbo pedistal. They're kinda known for getting leaky. Good info though to help differentiate between wether it's the supply or the return. (though the o-ring kits replace all the o-rings in the pedistal) IIRC, the seal for the EBPV can leak too. I'm not exactly sure where this seal is though. Probably on the back side of the turbo.

wow these things are just leaky bstrds huh? haha thanks cndrm

I didn't think OBS trucks had EBBV if they do it is part of the pedastal rear but I doubt you have one.

My 02 always had a slight drip I just ignored it.I drove enough miles in a month it wasn't down enough to worry about it.
