    I have a questions for mechanics wondering what the issue can be.

    I was driving and my low oil light came on so I popped the hood to check what’s going on and I the whole drive side was covered in oil after few minutes I noticed the oil dipstick is being pushed out by oil when the truck is on higher rpms I removed the breather filter and same issue what can this be caused by?

    Big oof on the MXS. That said check your crankcase filter to rule that out. Fleet i used to work for with a lot of 15s it was almost always a clogged crankcase filter causeing the stick to pop out. Could POTENTIALLY be a worn air compressor too but ive only seen that once.

    If not then the only things i know left to check are the turbo seals and blow by then? If thats not it then we have hit the limit of my experince and id guess you may have a worn piston ring letting gasses get into the oil. But no cat i personally have had access to has done so so take that with a grain of salt.
