Re: Got the head off; looks like someone took a cutting Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: Got the head off; looks like someone took a cutting...., TonyJ ![]() ![]() |
It could be as easy as that this particular valve got old and tired and developed a crack. When that happens it doesn't take long to burn it up (like a torch as you mentioned when the hot gasses are squeezed out through the crack during high compression).
It might also be an air mass meter that start to lean out and with the extra towing it just didn't deliver enough fuel to keep the valves cool.
Maybe the car is over boosting a little?
Maybe it was very hot and the engine was pinging more than usual, cracking the valve.
Lots of possible scenarios.
