On my car, the shop used the BBI coolant fittings and rather then welding they used a high strength adhesive to secure the fittings in addition to pinning. Almost 30 trackdays since and no issues.

I've personally seen several incidents on the track where coolant pipes on GT3's or Turbos have popped and dumped coolant. It's scary and potentially catastrophic. I also know of one 997.1 GT3 with only 10,000 miles and almost zero track time that popped its pipes.

It's a game of Russian roulette with these engines. If you drive on the track, welding or at least pinning the pipes should be mandatory. Mine are welded.

997.1 GT3 - prior to tracking it, I also had the coolant pipes blow during normal street driving.

Car had only 35K miles on it at 5-6 years of age.

Read the Sticky post up top - plenty of non-tracked cars with blown coolant pipes.

I've been told that if your coolant lines are not addressed, to keep an eye on them until you can. They typically don't just slide off all at once, but ease off over time. So if you don't know all the connection, have someone who does to point them out. You can tell if they have moved any from their original point. Check them each time before you drive the car. I agree with everyone, priority one is to fix them.

Are you asking if an inspection can reveal that a car was tracked, or that the cooling lines were pinned? An inspection can reveal both, but track use is easier to hide.

"Also - this seems like a fairly involved labor job - and sometimes I have found to have more things go wrong after there are mechanics messing with the car --- especially on a larger job."

try to find a shop that you can trust to not screw things up,

Good luck.

If you are NEVER GOING TO TRACK OR DRIVE "SPIRITEDLY" ON MOUNTAIN ROADS, don't bother with pinning / welding.
If you have a failure, you will likely not spin and cause carnage.

Do it, itll give you piece of mind and if it does happen you wont be stranded.
