    That is great stuff if you are working on junk. Would not put it in an over the road truck engine.

    Haven't had an issue with a CCV module on an EPA 10 MX, but Mack/Volvo uses a very similar CCV module on the MP/D motors. Had one dripping out the draft tube and covering the underside of the chasis and using a gallon of oil every couple days like needing an overhaul. Replaced the CCV and completely fixed the issue. Tore old one apart and the discs were soot packed. Gotta love EGR.

    I had a ccv on a epa 13 pour oil out the breather like crazy. Swapped it and it fixed it. No codes either. Only one I have seen so far

    Also it is common for the clips on the breather pipes to not get completely snapped into the valve cover or have the clips broken off so they dont grab properly. Hoses can also crack and leak too

    Yea i jus removed clips and hose and replaced rubber washer on each end of hose and reconnected and it fits tight now. I believe thats all it was too because top of ccv was covered in oil from hose leaking everywhere. Thanks for yalls help and happy trucking
