Last weekend I thought I heard a rotation or slight grinding noise before I put the ski away, and figured it was down in the pump area. I took one last spin to see if I could figure it out. I did! exhaust valve broke and dropped into cylinder. Bad news! I did some reading and these older skis had hollow valve stems. When I found this ski, it had sat for a number of years. From what I gathered there may have been some rust on the valve stem and the heat may have helped push the valve to its breaking point. Does this sound like the correct theory why I killed the head.
I am looking for suggestions on the best cheapest route to put this back together. I have completely torn it down and going to use the head off an 04 215 engine I have. While I am in there and keeping this project as a budget build, what is most important? any input is appreciated
Must do;
valves intake and exhaust
Complete gasket set
timing chain and guides
thrust washers for crank and balancer
spark plug tubes
new bolts head, cam and crank
1 piston and all rings (3 sets)
motor mounts
Should I replace:
Valve springs while apart
inspect oil pumps if not obvious damage
