Hi All, So I've recently redone my timing chain and in the process, replaced the water pump housing gasket. And this is where my problems start. I simply cannot seal the housing properly. I have tried the OEM gasket (purchased from Hall's) on it's own. It leaked out the top RHS of the housing. I tried the gasket with permatex ultra black on both sides (followed permatex guide to the 'T'). And it sprung a leak on the LHS of the pump (see yellow arrow) I then got rid of the OEM gasket and used permatex on it's own making sure the suspect area had plenty in there. Guess what? It leaked again in the same spot (yellow arrow). Now these leaks are very slow (1 drop every 2 min) but I'm lost as to why it's happening. I have noticed that this region (yellow arrow) is where the head cover join is. Should I put liquid gasket along this 5mm or so of join as well? Should I build it up on the outside of the housing? I know now that I don't want to use the liquid gasket without the OEM one. It makes it very challenging to get the water pump off again. So if I clean the permatex off the new OEM gasket, any reason I can't re-use it seeing as it's still fresh. Any help would be really appreciated. This persistent leak is extremely frustrating! Cheers!
Update: Leak now fixed. Required a combo of honing water pump housing surface flat, making my own gasket out of a better product, and permatex right stuff to deal with imperfections due to having a head cover join as part of surface to be sealed.

Wow. I had no idea that the gaskets were such a problem to seal the water pump. Thanks for the update, much appreciated.
