Liam:
I hope you mean bad diesel not gas. I still don't understand the chipped glow plug. Something had to chip it. Bad diesel or not, the only thing to go in a combustion chamber are diesel through the injector and air through the air filter and manifold. About the only way the glow plug could fail would be a really extended pre-heat which would destroy the tip. In that case, replace all of them. I don't want to sound accusing, but did you in the effort of starting the engine on bad diesel extend the pre-heat cycle considerably?? If you did, again, I'd replace all of them. You didn't use either?? That is a no-no. Please elaborate. /forums/images/graemlins/confused.gif We are all curious, especially Henro.
