Hammer the top of the allen holes , then hammer your allen back in for a really tight fit.

That trick never failed me.

you have to heli coil them you need to get a kit to match the thread of the bolts drill tap and install the insert

Helicoil, it's not a hack fix, it's a standard method of putting strong steel threads into aluminum. It works great for repairing stripped bolts, too.

Yea well I missed the last word of the title of the thread. :booboo:

True , even brand new 302 alu intakes or heads comes with helicoils already in them.

Supposebly helicoil is stronger then any stock threads (in alu).

anyone have the link for the heli coil?

you can grab that in any local autoparts store , you just need to thead specs to be repaired. Exemple M7 X1.25

If they have a little tool to measure threads size and pitch , I guess so.

Stay away from the Heli-Coil and go with EZ-LOK instead. Much simpler to install and this is coming from experiencing the same thing you are. You're looking for a M6 X 1.5mm thread pitch insert.

is there a enuf metal for the ez-lok or did you use the thin wall ones ??? i use the heli coils all the time and never have a problem at all

Plenty of meat there. I used the regular inserts but thin walls are fine. As long as the hole for the insert itself stays around the 8mm range, it should be fine as far as holding up.

The reason I like these is because they are solid inserts and easy to install. And they work. With Heli-Coils, you need the tool to insert it and break off the tang. These thread in with a regular screw driver. And sometimes the Heli-Coils have backed out on me. These don't because they're coated with Loctite.

1.5mm on a 6mm bolt? (runs to basement for confirmation)

You're right. 1.00mm thread pitch.

I confirmed it right now with a thread gauge.

 

[llamaking122]

ok halicoils are in. Do i really need to punch out that little prong on the bottom of them?

Yes otherwise you will bottom out.

Reviving this due to im experiencing the same prop with a striped bolt in my timing cover..im losing oil like mad tired of buying oil and the mess and smoke...i tried an ez out and said scew it..so now im paying for it. I plan on drilling out the bolt.... im not sure if to use heli coil or the ez lock. Like stated ez lock looks easier but which kit should i get. Someone point me the right direction here. Need this fixed asap.
