Worth fixing

Recommended Posts

Hello:

I am new to engine rebuild.   I believe that an exhaust  washer go sucked into the motor and caused the damage shown in the pictures.

The top end appears OK except for the cylinder head.    Little pieces of washer found all over the place.

Will the damage to the combustion chamber/Crankcase cause inconsistent burns?  Should if just sand it down?  Is the motor trashed?

Will the nicks and gouges in the cylinder head cause problems?

Can it be repaired?  Again, this is only my second rebuild so any advice would be appreciated.

Thanks in advance,

Bob

as long as the mating surfaces where the case halves go together are flat they are usable

the head can be machined after you test the head squish

Looks like a lower rod bearing cage failure to me, check the crank VERY carefully.

Rebuild or replace it more like I doubt it would have come out okay after that much damage to the lower end.
