Oil in Engine Valley...Where it Coming From?

[meanjean]

I pulled my turbo due to the fact there was oil under the turbo area of the motor. I also get oil to drip on the driveway time to time. This has been a minimal oil leak. I am putting on a Wicked Wheel so thought its a great time to pull the turbo, change the O-rings etc.

It doesnt appear to me that the oil leak is coming from the turbo or turbo pedistal?

There is no oil in the front part of the valley near the HPOP, I dont think thats the source.

There is oil residue on the passenger side, where the intake thing (not sure what its called) bolts to the block/valve cover.

Looks like oil residue on the EBV area also, does that have oil/seals that can leak?

Here are some pics.

Couple more. These pictures are taken from the front of the truck look to the rear.
Left side is where it seems the oil may be coming from? Valve cover gasket maybe?

(not about this though) So, don't take him as your Guru, as many do Confirm his advice on anything else he says

your EBPV rod is leaking from the pedestal. Either repair it at 200 buks or remove the system and put a plug in the hole wherethe rod protrudes from...be done with it then.

Might wanna replacethose plenum boots and clamps, with good ones and t-clamps.

mine looked just like that and it was the EBPV..mines been plugged with the wire unplugged for 2 years no problems..my second oil leak was from the intercooler boots in the 4 way pipe...while you're in there i would replace those as well with riff raff or dieselsites intercooler boots, theyre not too pricey...

Thanks for the help. EBPV is outta here!!
I ordered a new pedistal with no EBPV on it and will remove the butterfly valve myself to save a few bucks.
Question-
If I remove the EBPV and leave the sensor unplugged will the truck still "fast idle" when cold or do I need to trick the sensor with a resistor or plug DFUSER?

The EBPV plug is just for actuating the EBPV, nothing else. It's fine laying there. You might actually get a code, think I did, but it's a soft code; no light.

you could've saved a few buks, and just removed the rod assy from the pedestal, and either, put a plug in it or tapped the hole and ran a bolt thru it..either way, you eliminated a possible leak

For the ebpv itself, i moved the flapper arm over, like it was being actuated, then "tack" welded it to the exhaust housing. Or, you can remove it, and install a bung. If access to welder, i put a bolt in there ,then ran a bead around it...

i removed everything, tapped both holes and plugged them...yes truck will still speed up idle in cold weather after sitting for a few..at least mine does..

Did you remove the sensor on the front of the turbo pedistal? If so, did you leave the sensor plugged into the harness and just laying there or left the harness with nothing plugged in it?

Thanks
