Well, it's been said that better is the natural enemy of "good enough"... I'm working on transferring pieces of my old engine (OM616) to new engine (OM616). I decided to spring for a new water pump, on the theory that it was better to spend $52 now to change it on the bench rather than have to do it out in the cold rain sometime down the road.

Well, the previous owner (or maybe even PPO) glued the water pump to the housing. I got all five bolts out without breakage, but it just won't let go. I've whacked it with a rubber hammer, whacked it with a regular hammer buffered by a block of wood, but nothing budges. When I run a finger round the sealing crack I find vestiges of sealing goop.

I'm thinking of putting the housing in a vise, and then using a monkey wrench to try and twist it off. Or maybe heating things up a bit will break the seal?

Ideas?

Thanks in advance,

Kurt
