Broke a rod and damaged block and oil pan. Is it worth the effort to port good components into used block and pan. Or should I scrap it. The engine is on a Craftsman GT5000 with 48 in cut deck. I don't know why it broke a rod. I am told there was oil in the engine at the time of failure due to the large quantity that was expelled through the crack in the block. Does this engine have a high failure rate ? I found a block and oil pan- used, in good condition for less than $300 locally. Is it worth the effort to port over the crank, pistons, cam, etc. I have a Briggs 24HP OHV engine available that I paid $75, it runs good, is it possible to swap ? I don't see that this model Craftsman came with Briggs. The model number for the mower is missing. Inquiring minds want to know.
