Help!!!Excessive oil from rocker box PVC vent!

[karp72]

Hello fellas/gals,

I have a highly modded 03 XB9s with a Millennium 1050 kit and PLENTY of other mods but any way I have excessive oil coming from the rocker box vents.A re-rout has been done to the vent hose and there is a LOT of pressure and oil coming from the vent.

I guess Im asking what could be causing this?

Any and all info would be greatly appreciated.

Thanks Tim

have a competent experienced tech perform both an "operating temp/WFO" compression test.....then a leak-down test. betting it will fail #2.

Yeah,..I was thinking,...bet its the rear cylinder too.Its ware all the oils coming from.

Ill have to do both tests,then go from there.

If the oil is coming out from the rubber hose connector area, simply replacing the zip ties with a hose clamp and tightening it down may fix it. Mine were leaking from there and I found someone else's write up on the forum. I simply cut the zip ties off and replaced with metal hose clamps. No more leaks.

Sounds like you've got a lot of "blow by", in other words, rings issues. As recommended, compression test and leak down.

I had fixed oil leak on the PCV valve just cutting worn tip on the hose and applying and tightening zip tie. No engine rotation needed. Recently I totally replaced the old hoses.

none of this related to his post. notice " a LOT of pressure"? that can ONLY be caused by compression gases leaking past the rings/valves into the engine pressure relief system....or combustion gases doing precisely the same thing. completely unrelated to zip ties and hoses.

Yeah, pressure is a whole different animal. Follow Lunatics advice above.
