Re: What did you do with your truck today, Part 3
Ready for my fourth attempt to get my NPT head plug to seal. Tried once with Permatex Hi-Temp thread sealant - held a few weeks. Tried again with 3 wraps teflon tape - didn't hold at all. Tried again with a different plug and 6 wraps teflon tape - didn't hold at all. And yes, I've chased the threads with a tap.
This time I've got a new brass plug (the others were steel) and I'm going to try Permatex Form-A-Gasket #1 hard curing sealant. If that doesn't work, I may as well try to JB Weld the plug in, because I'm going to need a new head anyway. :-(
