Anybody ever used a Helicoil on an engine head?
 

III's car has a spark plug that keeps popping out of a cylinder. Don't really want to take the head off but they have used helicoils for years on quick fixes without removal of the head.

Anybody use any before?

Yes, I have. It worked fine. I used the kind that is enclosed, like it is more of a threaded cylinder on the inside and outside if that makes sense. Then I used some good permatex sealer on the external threads (to the head)

I was thinking the same, I have a mechanic friend I'm going to get to do it. I would but I'm laid up in a Physical Rehab Center, would rather III not try it.

Thanks!

Not myself but know others who had good luck using them.

I have used the insert type on Mercury Outboards that have no head to be removed. Coat the tap with grease to catch the cuttings from the tap. Use some hi-temp loctite on the insert. I don't really like the coils although I have used them as well on repairs that are closed at the bottom so the insert can't fall through.

What vehicle and motor?

I’m pretty proficient in these

Use the solid steel inserts then...

Bet III has a Ford, right? I had a spark plug blow out of the cylinder in an older (late 90s) Taurus a while back. Looked online and saw that it is quite common. At least for me it was when I started the car, not while driving down the road like a lot of reports I saw. :eek:

Chevy , 3400 engine ? Back center cylinder, Kinda of a bitch to get to.
