Oil spot

So I pulled my X out of the Garage today and saw a small, maybe 6-7" oil spot. It is a 2000 7.3 with only 40k on it. I had noticed a few months back that my boots around the turbo were starting to get dirty and it was actually on my agenda to replace them this spring. So I was looking ontop of the engine and right under the "Y" coming out of the turbo there is a puddle of oil ontop the engine block. Could all this be just from the boots? or do I have another issue? It looks as though it is running down the back of the block and dripping off the front of the tranny where they meet. Definitely oil though.

Thanks for any input

edit- or do i possibly need a CCV mod

6 or 7" spot all of a sudden.... Probably turbo pedestal o-rings or EBPV actuator leaking on the pedestal. If oil is in the valley all the way to the front, that would indicate that the HPOP is leaking.

The oil puddle is under the turbo almost.

Is the oil only in the rear under the turbo?

If so i'm betting on the pedestal o-rings.

Check the front of the valley thoroughly though. If the is oil in the front, then your issue is not at the turbo. It is most likely HPOP o-rings.

Both of these are very common places for the 7.3 to start leaking oil.

It's not quite as far back as the turbo, almost right under the boots at the "Y". and with all the oil recently on the Boots, i was wondering if it was them just leaking with the CCV oil. But I don't know how much oil would come through there either.

Buy front of the valley, where do you mean? and are either of these O-Rings a nitemare job? any leaks to the fixes?

Thanks Guys!!

I just went and looked at again, now that it is cold. I actually see 2 oil puddles on what would be the intake manifold on a gasser. (don't know what it's called on a diesel....) One is back under the turbo. The other more under the "Y" coming out of the turbo. They are maybe 4-6" apart and both are self contained in little "cups" if you will in the contour of the manifold. Hope I'm not confusing you too much. I see nothing that is clearly leaking. All the stuff back there is a bit grimy. But the drip is finding it's way down between the oil pan and the tranny. It actually is leaking off the black cover on the front of the tranny. There is a little nipple there and is leaking right off the nipple...

Yeah there is no way there is that much oil coming from the CCV. It will not create enough to give you a puddle under the truck
I mean under the HPOP. It is a real easy job to do. See pic

If it is that far forward, I would guess that it is not the turbo pedestal o-rings. Still could be though, pics would help. Any time there is an oil leak on the top of the motor, it will always end up under the turbo because the oil flows backwards.

This is normal. There is a hole in the back of the engine valley so that oil in the valley will drain down and out. It always shows itself there which misleads everyone to think it is a rear main seal. It almost never is...

Try this.
Get up in the engine compartment with the truck running. (be very carefull of the fan ) Using a flashlight and a telescoping mirror, slowly take a good look all around the HPOP fittings, and then the rest of the valley.(it probably won't be dripping very fast).

Let me know what you find.

Take some pics if you can, it would help a lot.

Good Luck
