I have used helicoils in the past but don't feel as impressed with them. I know timecerts are 3 times the $$ but I guess if we worried about $$ we wouldn't be driving these cars.
What are your opinions on both? I guess the initiall cost of the kit is the big hit but the inserts are not too bad for either system.
Opinions please.
Thanks.

I have helicoils on my engine. No problems. I always use lock tite red when installing.

I have been using helicoils for years and have never had any problem with them.

I have used both. At the BMW dealership where I work, we use Timecerts exclusively. Personally, I like the helicoils better. Either one works fine, but I think it's a matter of personal preference and experience. I have more experience with helicoils so that is what I use for myself.

The helicoil can do the job, but I think the timesert is superior product. I used them on my 911 case for the case studs and was impressed with the quality of the product. I also purchsed a M6 x 1.0 kit which is nice to have around as this size thread on Porsches has given me the most problems. It is my impression that a timesert in softer metals is superior to the original theads. When installed the threads are expanded to lock it into place and the top has a flange the stabilizes the insert and also leaves a clean flush appearence. In areas around moisture if creates a solid barrier and you will have less problems with corrosion of studs or bolts since the metals are now more similar. I agree they are way too expensive and it may take a lifetime of wrenching to justify the cost, but this is a product a 951 on this site clearly deserves.

There is a good discussion about timeserts in Bruce Anderson's 911 Handbook. He explains how they are stronger for high-torque applications, like head studs. Helicoils work great for run-of-the-mill stuff though -- my intake is riddled with them.

I can find no fault in this kind of logic!
