Well, I'm in the process of replacing my timing chain and after removing the cover I realized I had a little hole in the surface behind where the water pump lives. I had that hole repaired but the Hack welder who did the repair for me took it upon himself to grind the excess weld off the mating surface with a hand grinder!! Phase two. I had the water pump surfaced at a legitimate machine shop and am very happy with the work. However, looking at the back side of the cover (the face that mounts onto the engine block) I notice the surface is not true/flat. It seems significantly not-flat to me- I am no machinist but I do believe those guys work in the realm of .0001 of an inch and what I'm seeing is like a sixteenth gap on both ends- if you were to rock a straight-edge from end to end there is what looks like an eighth of a gap! One of the guys at the shop thought that being aluminum I shouldn't worry about it and he thought the bolts would pull it flat. Again, not an engine rebuilder-that advice sounds pretty hokie to me. ' The crazy thing is the one surface that hasn't been messed with is the one that is looking warped. Has anybody noticed this before with their timing chain cover? And, any thoughts about going for it and hoping the gasket and RTV will take care of the gaps? I am aware that I can obtain a new cover but my situation is that I need to throw this thing on now. My car lives in a remote place from me (Mexico) and I'm running out of time. I don't have time to order one (which I should have done in the first place- who would've thought the whole world was going to shut down after I started messing with my motor??) and have it shipped down here. I'm trying to close down shop for the season and right now I'd like to remount all the parts that came off with the timing chain cover.
