I am working on getting my MEP003A running.
I have a glow plug that ohm'ed out as being bad. I soaked it with PB-Blaster for a week, but of course it still broke off in the head! What all is involved with drilling it out? It looks like I have to, at minimum, remove the intake manifold. Does the glow plug just extend into the intake port above the intake valve? If so, can you drill it out while making sure the intake valve is closed so no metal gets into the cylinder, or does the head have to come off the engine?
Also, it looks like two of the three I removed from the engine were CH42, and there is no markings on the third. I see that some people are using the Champion CH42 as a replacement, but I see it has a metric thread at 10mm. I chased the threads on the unmarked one at 7/16. What is the correct thread size? Is anyone having any luck using (or finding) these? They appear to be ~$18-$20, versus the $50-$60 for others.
Any advice on which glowplugs to use, and especially on drilling out the broken one would be greatly appreciated.
