Thread repair

[Guest]

Has anyone used this,

Seems to be a good answer for the threads to tighten to valve cover down. I may try it unless someone steers me clear?

I have used this but you need to make sure the hole is very very clean.
Not a permanent solution a stop-gap measure but it works

the gas tank sealer these guys make is amazing stuff.

Am I better off using a helicoil.

If you have sufficient room to work and enough aluminum "meat" around the stripped threads to accommodate the Helicoil, that's what I'd prefer. Some of the valve cover bolt holes in the head don't have a lot of extra material to work with.

If you want to get picky, there are solid thread inserts that are much better, but they get rather expensive. A Helicoil should work fine in this application.

If you can get the hole clean enough, there's a good chance that the epoxy repair goop will do the trick -- there's not a whole lot of stress on a 6mm bolt, after all.


You could also re-tap the hole to 7mm and hog out the valve cover hole a bit, but that's more than a little bit ghetto. The next owner will probably swear a bloody oath of vengeance against you unless you warn him about the one oddball bolt...

I think I'll give that stuff a shot. I just can't stand the price of a new valve cover gasket since I can't make my own. Damn half moons.

the stuff is worth a shot
it closed up a valve train leak for me long enough for the internet and eaby to be born
im not kidding

I was reading about it, you put the release agent on the bolt and the other stuff in the female threads and screw it in for about 2 hours?

it a chemical thing but it does work for low torque situations
I find it odd the would have not reduced the time by now

regardless you are basically creating your won threads in teh goo by threading in the bolt

worht the ten buck more than worht it

Hell yeah, helicoil kit $40+ Timesert's $150+

Permatex $10. I in no way can bring myself to spend that much money to bolt a cover on. Everything adds up too quick.

Timesert's $150+

Not quite. Throw a Peeper here. ---------> Timesert Pricing

Not bad, I think the bolts are M7 though which is an odd size.

Ranger, pull the cap in question & bring to my house. I will Helicoil it for a 6 pack of Newcastles & drink them with you afterwards. I have the Helicoil kit & drill presses to do them CORRECTLY & do them all the time. The 1150s have the same cam caps. I am 3 blocks from Disneyland. Ray.

I'd use a new bolt to ensure that the threads are as clean and sharp as possible, but yep, that's the idea.

The OP was only talking about a valve cover bolt, not a cam cap. But you are one awesome dude for making that offer.

Say "hey" to Mickey for us!

Helicoil is what I'd do too. Fix the problem the right way, no disco repairs.
