(11-27-2018, 03:09 AM)zeeman First run of a used engine in my latest conversion. Engine was noisy, sounded like a piston knock. Then it started missing.
Ran a compression check, number 5 had hardly any compression. Pulled head off and this is what I found, the prechamber had failed. Anyone have an idea what caused this?
yes it is liquid fuel dripping onto the prechamber when the prechamber is glowing. Those prechamber tips get extremely hot and they cannot handle the rapid cooling. So if the injector starts to leak, the tip eventually falls off the prechamber and dances around inside the cylinder, which doesn't have any room for that sort of thing.
