What size glow plug threads?

[BC-IDI]

My 94 idi factory turbo is smoking white on all start ups, even being shut down for 30 mins after being at operating temp. Im going to replace all the injectors, return lines and glow plugs. (motorcraft plugs af course)

Getting ready to replace the glow plugs. Been doing alot of reading on the horrors of what could happen. I've read about and seen a tool to aid in the removal of stuck plugs. This tool seems fairly easy to make.



I'm just wondering if anyone knows what size nut I need to get that will wrap around the plug threads once it's cut in half?

Also, done a bit more research on getting the cylinders to top dead center. none of the articles that I have read have given a straight answer on the easiest way to get each cylinder to TDC.

can anyone help me with this?

I'm not sure on the size of the nut, but why do you need to get the motor at TDCC?

EDIT: never mind I see what your doing. Maybe this article will help you out

I would try to get the plugs out first before buying anything. We all hear horror stories but how many people have pulled the plugs no problem.

White smoke when warm doesn't have to do with glow plugs, sounds like a timing or bad injector issue.

That's said, those items you are going to replace will benifit your truck a lot. Good items to replace for a "tune up"
