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.

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 .
