Isx skipping under heavy oil load and small oil leak

[Luckyjayb]

It is the blow by tube and the oil fill in that pic. I’ve tried the jug method already and no major oil in there. A lot is blowing back on the engine from the fan engaging and disengaging. I’ve checked it meticulously and it’s driving me bonkers. I’m gonna order the new gasket for the oil pan since it is the original one and the motor has only 1,004,905 miles on it.

Yes, the pan gasket looks to be leaking pretty good for sure, but seems to be a significant amount coming from the blo-by tube as well. Maybe under a hard pull is when the oil is coming through?

Also, is that the fill tube going to the front cover (second pic)? On my 2350, thats where the rubber plug is located to access the face of the fuel pump I believe. It's what I used to turn the engine while setting my overhead. If there's an O-ring there, it could be leaking there as well. Multiple areas leaking some oil can turn into a mess quickly.

How much oil are you having to add between changes?
