Ok, I am at a loss here. The valley pan is in excellent shape, cleaned and straight. I copper spayed my cork gasket, layed it down then installed the valley pan. When I torqued the two bolts to the spec of 15 ft lbs I f0und, one side bowed up in the center. It is tight everywhere else and the bow is not significant but it is enough to have lifted to the point that the cork gasket is not tight. Am I missing something here? how do I get this pan to lay flat and seal well. This is throwing a complete monkey wrench in everything being ****oned up. Thanks guys.
Are You sure it's not bent ? Was it sealed before the tear down? Take the gasket off & Where it's hitting, tap it lightly and evenly with a rubber mallet - bending it slightly to get the gap to close. You might need to reprint it.
Good question, It was the factory sealing and if my memory is right it looked sealed but that was thru grime and nasties so who knows, it was straight before I installed it then it seemed to **** down on the ends n bow up in the center on one side. After google shoogling I see getting these to seal is not always easy so I am considering using black " Right Stuff" sealant and doing the gasket that way though I would rather understand what is going awry
Did these engines maybe originally use some sort of a special shouldered bolt that prevented the cover from being pulled down too far and distorted when it was installed?
I ussualy put a thin coat on the gasket to hold it ( ussually the night before and let it set upr and adhear to the cove) and put a 1/8 bead on the engine sides and put the valley cover on then torque slowly in 4 steps back and forth between the 2 bolts to evenly pull it down , otherguys I know don't use a gasket and put a bead of silicone all around then tighten them down and fill the gaps up after its secured from the top , just try to keep the ammount of silicone down so it doesn't plop in the motor and plug the oil pump.
Maybe your torque wrench is incorrect..or you read it wrong....I would have just tightened them.NO torque wrench needed
If it bows up in the center of the ends then its LOW in the middle. Low because the bolts are too tight or its bent.
Well, took it off n kept the gasket in one piece, couldn't detect any warping that was there or Re-warable in the other direction so I went the route or permitex grey all the way around and solved the issue, it was such a small amount of lift that it looks fine now , thanks for the help guys
is there usually a certain order of tightening the bolts down? like cris cross tightening and not torquing from the start. snugging all bolts then torque? Posted using the Full Custom H.A.M.B. App!
