The melted piston has left some aluminium on the bore, i am hoping it will clean up. We will pull the engine out and dismantle later this week, plan is new piston and rings all round with a good hone. Would like to know everyone’s thoughts as to what may have caused this to happen.
We do not have much history on the car, it has sat unused for around 10 years or even more. We have only had it running for about two hours.
Colin,
You say the car was unused for 10 years - was it stripped and checked before running ? There appears to be rusty water on the block around the valves.
Personally I would never run an 'old' engine without a thorough check. Stuck valves would be a good place to start.
We did stock the black/copper gaskets a few years ago- all sold now. Out of interest we have had a problem with some New Zealand supplied gaskets.
Was it Number four ?
Cheers, Tony.
