SignUp Now!I'm running -12AN lines from ea valve cover to a catch can right now. That seemed to help but now im getting a thin film of oil from the back of the valve covers that coats the engine. That film then forms a tiny drip off the torque converter cover. I've tried sealing the covers to the heads 4 times already w all the same luck...Those covers just don't want to seal and yes it's driving me completely nuts! Lol
I tried silicone and that didn't help. I'm going to check it tomorrow w the fresh set of passenger covers and these nicer MAHLE gaskets. Lubed up the gaskets too w MOLYKOTE, o-ring grease. I also cut down the support rods inside the covers 1/8" below the lip and made them all flat. The castings from a couple of them appeared that they were protruding past the lip of the covers maybe not allowing them to seal... I have Cummins engine oil dye in there now and a UV light ready! Hopefully no more leaks.You can cut off the bottom edge of the acorn nuts, sob they tighten a little more, or you can add a 2nd washer on top of the valve cover. I put a thin layer of rtv around the back of my gaskets, and it stopped my leaks.
So after all this dicking around w the valve covers. The engine oil dye came through and pointed the leak out. Head gaskets are the cause of my oil leak! Do I pull the covers and torque the heads down? Motor was just rebuilt.
No I didn't. I just pulled the passenger side cover being the easiest and checked the nuts. All the ones I could get to were tight? Had the torque wrench set to 60ft/lbs, none moved. Is it ok to drive as is or do I need to pull these heads off? I guess I could pull the manifolds and try re torquing all of the nuts. Just don't know if manifolds will come off due to manifold studs being installed as well...Did you re torque the heads after a couple of heat cycles?
CYLINDER LEAK DOWN TEST - Passed, all 6 were under 10% most were around 5%
Pulling the engine next week to retorque the heads. The reason behind that, Exhaust manifold studs are in the way of the nuts...alot of bs for some simple bs lol.
