Older Box? Considering headers?

[root_werks]

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.

Time-Certs are indeed the way to go.

Porsche even uses them for broken head bolts. I had 2 broken bolts on the bracket which holds the front sway bar and discovered this when I installed my M030 Front Sway bar.

I had a discount service coupon for the dealership, 1 Hr. Labor for $45, and so was able to have them drill it out and insert the time certs for less $$ than I would have spent on the tool and certs alone - the only time another mechanic has ever touched my car - nerve wracking to say the least.

They did the work in an hour and the lead tech who did the work said that it was just as strong if not stronger with the time cert than originally.

Cheers!

Good job! Glad to hear everything finally came appart. This is a project I wager I'll be doing myself someday.

Pelican Parts or GRP parts should have the TimeSert kits. Locally, I'm not sure would would carry them other than a good auto parts store?

As said, the kit include the counter sinking bit and installing tools. If done properly, the finished product looks like something the factory would do. My kit is almost 20 years old now. I have 2-3 little bags of that 8x1.25 Porsche exhaust stud inserts.

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.

Regards, Maurice.

Repair now delayed, timesert repair kit ordered, I'll get back to you all next week..


edit* I was searching the net and read going with the helio first is a good idea as if it fails it can be upgraded to the timesert, whereas a failed timesert makes a harder repair, so tomorrow we dance.

Sorry, eights, but that is a bogus claim. ANY failed repair makes further repair more difficult and less likely to be successful. Waiting for the proper insert is the ONLY way to go.
