Well, I have some updates and a new question.
I contacted the mechanic who did the gear cover replacement for the previous owner. It was done in situ, and that is very difficult as there is a v-drive, so he was working on the back side of the engine. When he got the cover off, he found that the block itself was corroded and the sealing face was affected.
He built up the block with Benzola epoxy
, put it all together, tested for leaks and found none. About 50 hours of run-time later I was seeing leaks.
I've gotten my head
back there while running, and I can see oil dripping down along the edge of this joint (can't see into small dark area where it's coming from). I can also see small amounts of oil weeping from cracks in the epoxy
I don't have a lot of cash right now, and won't until the fall. I was thinking about pulling the engine in the fall to sort the issue. I just finished a great diesel
course with the bluewater cruiser's association where we tore down the top end and accessories of a engine and put them all back together. Loved it. I'm actually eager to do the same with mine now.
So here's the question... If I plan to pull the engine in the fall, what are chances at that point that I can rescue
the block using a reputable welder and machine shop to build it back up and machine the face smooth? Can you even weld a cast steel
block? What would that cost?
The advantages of doing the repair are that I get to rebuild
it and really get to know it while it's out, I don't have to worry about footprint adaptation, and I should save some money
If it's a slam dunk that I can do it, then I may put some other money
into it right now while it's in place (like rebuilding the water
pump">raw water pump that's spraying salt water
onto the engine and causing the corrosion). If it's unlikely to work, I'll just leave it be and not put any money into it over the summer.
Thanks for your help.
