Can't speak to that as we never got those here. Is the cooling design similar?

 

I asked for a family member and I was told that it was not an issue for 997.2 Carreras. We know this is still an issue for 997.2 GT3's. So I guess the info can be both true and false at the same time. Just depends on what vehicle you have (couldn't tell, didn't see any forum sig or anything in post).

Yeah....I'm reminded of my friend who received some damage thanks to oil dump from a guy that blew his motor. And no one was mad in that case because it was accidental and the fellow was the one with a hole in his motor after going from fifth to second (instead of fourth). Spills out on track generally suck period.

In this case, it was intentional. Yes people take risks just by going out on track. Anything can happen. But it would just leaves a bad taste in my mouth intentionally put others at risk (until late spring of next year!) and having them unknowingly assume the potential risk and costs/damages.

Good on you for sharing though, great reminder for people to get the pipes pinned and otherwise not ignore safety. It's not just the pipes, make sure to also do other things pre-track such as check rotors and pads, etc.

I'm surprised we even have coolant pipe stories still, these cars came out back in 2007. I thought this was a thread necro-bump at first. Haha.

Saw a coolant line failure thing as a sticky in the 996 GT3 section. From the sound of post #324 and #260, it basically sounds like Same S. Different Day.

Anyone with the 996.2 engine case vs made in Spain cases had there fittings pop? Mine was a Spanish case. I know some of the cases for the 996.2 were made in Germany. I believe all 996.1 cases were all German. I'm n

 

Yes, there are .2 cases. Mine was after the car was parked just after coming off track.

 

>We know this is still an issue for 997.2 GT3's.
How do we know? I tried reading the long sticky on this and it seemed all the problems were with 997.1's.
The reputable show I use told me they have not had any problems with 997.2's.
I'm looking for hard evidence, examples of 997.2 failures.
I do a lot of tracking and do want to get this fixed if indeed it is a problem.

 

oops: "reputable shop"

See the brownish stuff on the pipe connected to the hose? That is a fitting that popped.

Deny if you'd like but Porsche did not fix this. If you track get it fixed. Run water wetter at a minimum.

Any shop that sees these in volume has seen loose fittings and popped fittings on 2010+ models

 

997.2 GT3 let go in front of me at the track. It wasn't "catastrophic". Just started leaking. The guy came in next lap and 5 minutes later all the coolant was on the ground.

The car was owned by a member, he can speak up if he wants to. Driven regularly. A few track days a year but nothing crazy. Treated well. Maintained well.

My thinking was very much in line with you till I saw that. Next time my car went in for semi-major work [Guard diff in my case], I had them pin my lines. Interestingly, the lines appeared and felt totally fine on my car. Making the expense even harder to justify. Oh well.

 

My Turbo started leaking from one of the three elbows off the oil cooler. Dropped the engine and found two fittings that were loose. Get it done. No point waiting for it to let go. And get the sharkwerks elbows while you're at it.

 

Having been behind 2 incidents, 1st thing I did when I bought my 997.1 was get the pipes welded. Accidents happen. But this is a known problem. Don't know why clubs don't insist GT3's have the pipes welded or pinned. Or run water.

 

My shop has welded the pipes on several GT3's. On mine the pipes had loosened up quite a bit and almost certainly would not have made it through another track season. They said they saw issues with the other GT3's, including coolant starting to seep and one GT3 with low miles that actually blew a pipe fitting while being tested on the dyno. Sad to say for Porsche engineering that these pipes are ticking time bombs.

 

My fabricator has welded the fittings for quite a few local cars including a 3.8 RS. There was some speculation that the .2 fitting design was changed to a deeper pressed fitting, that is not the case...they are the same. The glue on the 3.8 cars is a different color but rest assured the .2 cars do still have this issue.

 

Never seen a .2 GT3 have a problem . Mine had over 26k miles with many on the track.

 

Is this also a problem with Mezger turbo's?

 

All Mezger 996/997 cars, so TT, GT2, GT3.
