Hi,


I would like ask for some suggestion and experience. I just recently replaced the P Gasket on my 300 Tdi. It was an ordeal getting the water pump casing off the block since a bolt snapped and the rest was frozen in the old casing. I had to cut the bolt which them ruined the P gasket mating surface. I then ordered a used casing and put everything back together with a new metal gasket without any grease or sealant. I noticed it was seeping with the engine off. I tried tightening the three bolts but unfortunately it did not seem to work and it still seeps.


I have been reading that sometimes old water pump casings will warp causing new gaskets to leak repeatedly when replaced. When I replaced it I cleaned up both services very well and did notice a small amount of corrosion on the aluminum but it did not seem enough to cause a problem. Possibly I was wrong? or do folks think it might be warpage? Has anyone had this same issue and solved it by getting a new casing?


Thank you, I appreciate the help!
