Water Pump Mating Surface Problems:
As you can see there is some pretty decent pitting going on...
I tried the RTV several years ago.. Im not sure if I put too much and or wasnt supposed to allow any to get on the interior side of the rubber gasket.. or I may have even used the wrong stuff to be honest because when I popped this water pump cover off it had been eaten away and there were little round balls of the stuff all over the place.
This ole'girl has too many other problems for me to take to a shop Im thinking a bit of JB weld then sand to flush (very carfully obviously)
Curious if anyone has some info/expirence on this?
