Another Oil Leak, Oil in Valley, etc.

[94redbeauty]

Hey guys, didnt want to hijack that other thread going, but looking at my turbo pedistal I can see oil has been coming down it, and there is oil in the valley draining off the back of the block, what should I be looking for as to tighten, replace, etc....thanks.

do you mean at the bottom where the EBPV piston connects? I had it there too and washed it off to see how quickly it returned. Oddly, it didnt. I had had my valve wire disconnected for several months and there has been discussion on leaks coming from the pedistal when the rod is disconnected or unplugged. I plugged mine back in and it has not leaked since.

Try washing it off and seeing if/where it starts again. It's not much but it's something to look at.

Ive done that, and I dont know if its just from vibration but there is oil in front puddled of HPOP, in back puddled, and can tell that its ran down the pedistal, so I dont know if the EBPV is leaking and then moving all over the valley or what...I was gonna hook up a DIY exhaust brake, think that would stop it from leaking if it was or are there O rings that go bad?

there are o-rings in the pedestal. Dont know if they randomly go bad or not but here is a pair you can order for $13. Dont know if you can get them from a local shop or not.

Your leak sounds significant. Im not much help but that link will get you o-rings if that turns out to be the problem. Good luck. SOrry I cant be more help.

Thanks Tx, so I am guessing you have to pull the turbo to do this? -popcorn

Clean it all off again and isolate all the leaks. If it's puddled at the front that normally is NOT from the EBPV.

As JOAT said Isolate it, I have had in the last 6 mos, the top and bottom pedistal o-rings leaking, and recently the EBPV actuator. I take mine down to the car wash and high pressure the valley. It some times took me driving 5 miles at a time to see exactlly where the leak was coming from.

If you do the pedistal do all the o-rings, top and bottom, or you will be doing it later, or you could be like me and do the turbo o-rings 3 times not my fault the the rebuilt turbo and pedistal were warped.

Think about gutting the actuator and sealing it for good. DieselSite has a rebuild kit for around $115 I decided to stop the leak forever with a 45 cent plug.

Thanks Kansas, the O rings under the breather on the drivers side valve cover are blown out so oil is leaking out of there as well, ordered the O rings, of course completely wrong, send me some round one with an edge a another tiny thing, so yeah gotta run around town trying to find that. After that I am gonna whipe er down completely and see where its coming from, I guess if its not coming from the sides or the turbo its the HPOP

I had to use some good sealant when I did the breather o-rings, I finally put worm clamps on the little hose going to the intake so I wouldn't have to remove that breather assy anymore.

Also one of the first leaks I had was the HighPressure oil line going into the heads, those o-rings were leaking.
