    I noticed a leak on one of my trucks. While moving some trailers. While the motor was running I left a small drop smaller that a dime then I look under it and seen some gunk look like some blow by. Pics attached. I took the pictures from the drivers side right behind the front wheel. Gonna see what I can see in the morning. Any ideas? Or things to look for in diagnosing the problem? All help greatly appreciated. 20200529_222202.jpg 20200529_222240.jpg 20200529_222202.jpg 20200529_222202.jpg 20200529_222240.jpg

    It's probably the cam housing gasket or the valve cover gasket.

    Yeah, you’re going to have to clean the engine a bit to get a better look. It can be the air compressor or the fuel pump.

    If its not coming out from top then you need to change o rings of air compressor and fuel pump. This usually happens around 800k miles. If its coming from top then could be cam housing gasket or valve cover gasket .
