Oil Leak
 

Is there anything directly below the #6 valve cover on the back of the motor that can leak oil? I've got oil spraying onto the firewall from right there. I thought it was the valve cover but I swear I've screwed with it 3 or 4 times and its still leaking. Just wanna make sure there's nothing else back there before I pull it off and clean it again.

unused diesel fuel from the injectors joins a "T" then returns to the tank back there:humm:

Yeah I saw that but this is definitely 100% oil. Guess I'll screw with the cover some more. I'm wondering if its bent or something.

time for a duramax conversion, now to just find money

3208 cat next

cummins for a 3208 cat:nope:. u may as well swap in a 6.5 and call it good lol
as for the question valve cover bent not likely. there aluminum so i would say put new valve cover gaskets and c what that does

All gaskets were new, but I think I figured it out. That eyelet that bolts up right next to it is bent and was pushing it off possibly just enough to make it not seat up all the way around. We'll see tomorrow.

thats good. keep us posted

Cam may be walking out the back of the block.

seems to have stopped but maybe i'll check. wouldn't at all surprise me with this piece of shit.
