A friend was helping me with some carb and manifold work at one time. I was working on the ignition while he was installing the manifold and carbs for me. This was about ten years ago so it was still the original stock engine. Evidently he had a tinkle-punk moment and lost a lock washer. Never told me.
THREE MONTHS LATER, as I was pulling into the garage returning from a long three day weekend, there was a bang and then a clicking sound coming from the engine though it did continue to run and idle without a problem. This was a very unusual sound and circumstance so I was concerned.
After a lot of investigation it was determined that I needed to pull the head. When I pulled the number one spark plug, the electrode was smashed and ceramic broken. Hmmm, thats not good. Finished pulling the head. Found half a lock washer in the cylinder and the other half still in the intake track in the cylinder head. Found the tinkle-punk.
Resurfaced the valve, cleaned up the face of the piston, put in some new spark plugs and put about another 20,000 miles on it before I pulled the engine to replace it with my performance engine. That engine is still sitting in the corner of my garage and still runs just fine. /bcforum/images/%%GRAEMLIN_URL%%/smile.gif Sometimes you can just get lucky. /bcforum/images/%%GRAEMLIN_URL%%/smile.gif
I still have the spark plug and two halves of the lock washer. Part of my personal 'Hall of Shame'. /bcforum/images/%%GRAEMLIN_URL%%/frown.gif
