yea, while having to spend 4k+ to remedy an issue that Porsche should have handled isn't nearly as rewarding as spending that money on other fun things for the car, i do have peace of mind now.

i noticed in one of the recent GT3 for sale ads that a dealer did the engine drop and JB Weld approach, but no pinning/welding. that looks like what the shop in San Diego does too (the one in the video i linked to above). will be interesting to see how well that approach holds up over time.

Thank you Chris!

We definitely do not recommend using JB Weld, considering the labor costs to remove the engine and diassemble the top-end.

yea, i could see using a JB Weld only type approach if it was something you could do without having to drop the engine.

since that's not possible, not sure why you wouldn't employ a more mechanical solution (pinning or welding) along with using a "better" adhesive. i went with the BBI pipes and pinning on my car.

Same amount of labor as welding in removing motor. That said if you don't have an alternative, I believe JB weld is a much better option then pinning. I have used the JB weld on projects before. Stuff holds forever in the conditions these fittings will be in. Full disclosure, my lines are welded + bbi inserts + jb weld on top to make sure no pins on welds.

Welding (bbi inserts) > JB Weld (oem inserts) > pinning (oem inserts) . pinning only prevents hoses from popping out. It's an argument I won't get into as I know some people feel passionate about about pinning.

Buy some JB weld at your local store, get 2 metals and go play with it. If you need 10,000 lb iron I-beams to see how much weight JB weld can hold together, ping me. I'm in the SFBA we can test at my facility.

As for BBI and pinning...well If I were to pin. I would have reused OEM inserts. You won't get or you will get very little glue in fitting using BBI fitting and OEM casting. Tolerances are super tight with BBI. definitely design for welding.
Therefore you will be more prone to leaking.....

BBI- beautiful welds. What a joke- JB weld.

I am sure many Mezgar folks have put a lot of thought into what repair would be best for their coolant pipes, and proceeded accordingly. There is the greater cost factor to those repairs that require the engine to come out of the car, but if one choses to try the JB Weld approach, there is always the possibility that a subsequent failure of one or more of the pipes would mandate replacement of the whole coolant manifold. But then, I have never handled a coolant manifold so how would I really know. My own opinion, and recent course of action was to fix the pipes once and do a permanent repair. Had the BBI pipes welded in. One and done, as it were.

Can't wait to go and get it from where it sits now in Kansas City, awaiting repair from a likely spark plug failure. Going to take the long road home back to SC.

Was shooting an IDPA practice competition last night in a very hot indoor range, my hands were so sweaty I had a hard time getting a secure grip on my custom 9 mm 1911 pistol. Have a thousand round box of 147 grain bullets coming today, need to get my progressive press going to make my competition rounds. Fast cars and shooting just naturally go together.

Now to make up some of my favorite morning grits.

All the best....

Clearly my guy does not get the same appreciation for his welds like bbi does, nor how clean the parts were cleaned and processed with NCP.

Filed with NHTSA, this is my 2nd metzger that happens to it and just an email/ call from a gentleman and nothing happens.

Is there any relation for this issue to mileage or years? Mine is an 07 with 14k miles. Never tracked other than a few times in the past two years since I've owned it. Planning on doing much more this year. My shop owner who pretty much only works on cup cars 996/997/991 and ran ALMS teams with some RS street cars like mine who I trust 100% really doesnt think this is an issue. Doesnt want to say it but I sense he feels its a money grab. He said he'd do it but really thinks its over hyped. Clearly its seems to be happening based on this thread. I'm just wondering if there are certain factors that may lead one car to have the issue over others.

Thanks.

I've seen with my own 2 eyes these fittings pop at the track. And the fun that follows isn't fun.
The issue affects race cars. The problem here is that the race cars time out the components before they fail. Additionally, race cars run harder but have a lot less miles and heat cycles/time than street cars.
I did this preventively and 2 of my fittings were not tight and came out with minimal force.

Your shop guy is not BS'ing you, if his experience is mostly with race cars. But I wouldn't call this a money grab.

Try to tie this with other preventative or needed maintenance and the bill is easier to swallow.
