Older Box? Considering headers?

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.

Since they are on order I'm going to wait, I have two helios, one per side in the same spot one is suspect the other is very tight, seems like a waste to destroy the one that is likely to hold but I might as well do while it's apart.

Just wanted all to know the headers are in, I used one timesert per side and both snugged up tight. Unless there is more exhaust pressure in gear I'm confident they are leak free. I crawled under to check and blipped the throttle a couple times. Everything seems tight and beautiful sounding, actually far mellower than I expected which I'm glad about.



The plastic shroud is close to the headers, I'm tempted to leave it off but I'm thinking about buying more heat shield, which I used on the PS line and coolant lines on the other side. I thought I'd make a barrier between the headers and cover, any thoughts?

Thanks to all, BTW timeserts appear easy in the video because the dude is on a bench, when you're on your back and deploying speedbor extensions, not so much. The happiest grin of two weeks was when the second of the two socked in tight.

Way to go! Wait until you take it for a nice ride on a sunny day with the top down and the exhaust note singing!

I wrapped my PS line, but nothing else. I'll have to take another look now that the weather is FINALLY getting nice. Maybe it depends on the shape of the headers.

If the pipes look too close to the plastic underbody panel, a barrier is a good idea, as long as it doesn't jut down past the underbody panel.

Again, you have just made very tasty lemonade from those lemons! Congrats!
