I had my truck parked recently and someone jammed a rag up my blow by tube. I didn’t notice, when I got home the truck was leaking oil pretty hard and I crawled under and noticed the rag. Wondering which seal you guys figure the pressure would’ve pushed. Haven’t had time to check but looks like it’s coming from the drivers side of the engine.

 

What the heck!  Who did you P off?   Check the tappet cover gasket and the vacuum pump.

Tappet cover is the most common and easiest gasket to blow out. I'll tell you it MUCH easier taking the extra time to remove the injection pump to do the job right.

Very accessible with the cylinder head off too, just a bit more involved.  But I did do mine when it was off a while back. Kidding aside, after my first went bad I decided then just to do mine whenever I was that far in. The gasket is cheap and easy to replace provided you are in there.

For me to change a VP44 my average time is roughly 1.5 hours period.
