    Just take off the cover, clean it well and slather on some good jb weld epoxy.

    Saves you from buying a new cover.

    Will the glue hold up to the heat in the engine bay?

    yes i have used JB weld to cure porus aluminum engine cases before...

    if it were me i would park it , wait till engine is cold clean area with alcohol and apply Jb weld in place then let it set for 24 hours. . i would try that before removing cover...

    If you do removed the cover its not a bad idea to helicoil your hpfp holes. They are easy to strip out over time.

    Also replace the oil control rings with the new revision ones that are plastic.

    So does anyone know what would cause it to crack? Itís in a spot where it shouldnít be in contact with anything on the outside.

    No problem.

    Let us know how it works.

    Should hold just fine. Considering my transmission has a hole in it thats plugged with a stick of jb weld with 3 layers of jb weld epoxy over it.

    Kinda worried that something hit it internally, maybe the chain stretched?

    Mmmm you would hear it. Is it making a strong sound back there? Also depends on miles. I know a guy on here with 300k miles still on original chain and tensioner so who knows?

    Follower wears out, HPFP tip breaks off, catches in the chain and gets slung into the side of the housing. That exact scenario happened to me, but my housing isn't cracked from it, but there is a nice gash on the inside of the housing.
