Re: Water in Cylinders
Thanks for all the helpful responses. I have stripped gas engines all my life, but never a diesel suffering from salt water ingress. But Iím learning a lot from this present escapade, and working on this three cylinder baby is certainly easier than a V 8 350 chevy.
I soaked the bores with penetrating oil for three days, it went through #1 & 2 cylinders, but # 3 stayed full. I guessed this was the most solid.
Today I hoisted the complete motor and genny using a tackle from the saloon hatch, and supported it vertically on blocks. After removing the oil pan, (having drained it), I then unscrewed the big end bearings of each con-rod in turn. With a socket on one of the bolts I drove the pistons out the top of the bore with a lump hammer. One shot out like a rocket, one was stiffish, but #3 was a bearóit took a few hard whacks to get it to move, but once past the rings it came out easily. The rings were completely stuck to the piston, but the others were quite loose.
I think the pistons might be reclaimable, but Iíve decided to buy new ďpiston kitsĒ which includes new rings and pin, like Mechsmith recommended. Itís $100 more for each piston, but I think it will be worth it rather than trying to clean up the ring grooves and fit new rings myself.
The bores seem okay, but Iím going to hone them anyway. Never done that either, but I can follow instructions.
I also borrowed a valve spring compressor from Discount Auto, and plan to re-bed the valves.
I sure hope all this does the trick, but if anyone has any further advise I will heartily welcome it.
