Another possibility for oil in the valley?

[99' Powerstroke]

I have had oil in the valley for some time now and can't really figure out where it's coming from. The turbo pedestal is dry with no signs of oil leaking from or around it, and there are no signs of oil coming from the HPOP. Everything there is clean and dry. There are signs of oil coming from the intake manifolds but I could never make sense of it until I put my finger underneath the manifold where the red boot connects and came out with a big finger full of clean clear oil. The hose clamps are tight, but there is still quite a bit of oil coming from them. The red hoses are not ripped or torn because I checked them out when I put a new turbo on. I guess I could do the CCV mod to fix it. So has anyone else had this problem?

the o-rings on oil rail or hpop and you can not see it.i get clean rag and wipe it all around fittings and then start truck and let it run and wipe with clean rag. most the time i can find the leak.the hpop gasket could be leaking too.
very hard to tell. clean under hpop and then i lay clean rag under there and start truck then turn it off and pull rag out to see if oil is on it.but this is how i find leaks in valley

I would do the CCV and see if it stops the oil. Did you check the EBPV actuator on the back of the turbo pedistal?

Are there any downsides to doing the CCV mod? Also if oil can escape from the IC boots does that mean contaminants can get in and end up in the engine? or is the whole system pressurized from the turbo so it will only spit stuff out and not let anything in?

Reach your hand down under the HPOP... there are notorious for leaking ...

This is the typical results of not doing the CCV mod and many miles, the boots become saturated with oil and will eventually leak through and around the boots and fill the valley and eventually drp down the back side of the block. The CCV mod will cure your problem. There are right ways and wrong ways of doing the CCV mod. Chgeck your PM for the best way.

if your getting that much oil coming from intercooler boots there is something wrong!!! like blown turbo seal.

No if oil escapes the IC boots it doesn't mean contaminants will get into the engine. Just means you have a little boost leak.

the best thing to do is, clean the oil out and then use brake cleaner and then idle your truck and see if you can tell where the oil is coming from
