Older Box? Considering headers?

[landrovered]

X2 step away from the car when frustrated, tired or hungry.

I had a head bolt round off on a V8 and after a few days of cogitating on it I was able to come up with four methods of getting it out. Number one actually worked without having to resort to welding a bolt on, drilling and tapping and other more extreme measures.

Heat is not even on the extreme list if it makes you feel any better.

Wow, I never felt so much empathy from people I only know in type, thanks, it means a lot today. I just returned from renting a very good acetylene torch. I'm a bit reticent about using it, but I think it's necessary. I guess the only laugh today was the RR side came apart like butter... What concerns me the most is the helio coil, it's in there well, (I converted that hole to a stud) maybe it will suprise me and work right.

PS When I was doing my serpentine belt, I found the insulation above the area to almost be hanging into the belt path, I wanted to let EVERYONE know that. Also, if you are ever removing the tensioner, take the pulley of the PS pump, three bolts makes the job easier..

Take that Helio coil out (looks like a spring correct?) and use a timesert:

Done a thousand air-cooled Porsche-VW broken studs in my life. Coils are junk, don't hold up at all. Timeserts are the solution.

Keep the updates coming!

Wow, that looks good are they available in any retail stores? I really worked hard to get the coils well seated. I looked all over for a converter for the taps to connect to a ratchet but no luck. You cant cut thread as well as I'd like to do to this restriction. I think I'll try them and if there is an exhaust leak, I'll just pull it back apart and start from zero, that is unless I can buy these today and the extension.

Thanks, oh and I never needed the torch, Sears Cobalt bits, worked like a charm. It's ready for a test install.

Outstanding, good to hear!

The parts just arrived, I'm going to try to find those other inserts, otherwise tomorrow morning I'll do the test hook up.

Thanks to everyone for the mental, moral support, I never imagined fasteners would be as crazy as they were.

Excellent work!

Once you get everything installed, because you were able to prevail, the headers will feel that much sweeter!

I owe you the most thanks, our phone conversation completely rejuvenated my desire to prevail. I just hope the one helio doesn't leak, if it does, I'll have to look into those timesets.

It's your perseverance that got it done!

When I was having my "little adventure" with the four broken exhaust manifold studs, I researched the possibility of an insert. Two articles that I read were very emphatic in their praise of TimeSerts over the "old heli-coil" inserts. Fortunately, I ended up not having to use any inserts.

There is a company that sells the TimeSerts, along with the special tool needed for a perfect job. Not expensive, either. One of the aspects that impressed me was that the TimeSert will sit flush with the surface of the cylinder head and the special tool goes inside the insert to expand the innermost part of the insert against the base of the hole.

I'll look through my notes to see if I can find that reference and post it.

Regards, Maurice.

Eights:

Found the link. It's the link to the company's website and it has all of the metric sizes available, as well as an excellent video that shows you the foolproof procedure: http://www.timesert.com/html/mtrcsert.html

Once you are on that page, also click on the link that says "Click Here for Video Installation" and then select the two videos that are entitled "STANDARD BOLT REPAIR DEMONSTRATION" and “STANDARD BOLT REPAIR CLOSE-UP”.

The key advantage over the heli-coil is that the insert will not back out and they claim it is stronger than the original threads. The bottom three threads are apparently the ones that get "expanded" to lock the insert in place.
