Same one popped on mine @ 75K miles during a 1/2 mile pass. From what I've seen that fitting seems to be the most likely to pop. It and 3 or 4 other fittings are in the same spot. behind the alternator. You don't need to remove the engine to access them, just the alternator. I used marine epoxy to re-attach mine and then pinned it and the other ones in the same area. I have 3 or 4 left in other areas of the engine and will do those when I have the engine out for clutch/turbos in the next few years.

I would personally recommend just having the lines pinned that you can easily access and leaving the others for engine out work. It will drastically reduce your chance of getting stuck somewhere.

Also, my car has never been tracked, but it's done a couple 1/4 and 1/2 mile drag events.

 

My last car had over 50 track hours when I sold it. One pipe seeped at some point and was re-sealed. Otherwise, it never had an issue. I'd pin them when the engine is out. But otherwise, don't let it scare you.

 

I didn't let mine scare me and it popped in Battle Creek, MI. If I would have just taken some time to pin the fittings that are easy to access without dropping the engine I wouldn't have had to arrange for a 3 hour tow home.

 

I’ve got 47k on my 2003 and they aren’t pinned. I’m going to do all the easy ones this summer just to be safe. Next time engine needs out I’ll finish it.

 

Mileage doesn't really matter. Its glue, it breaks down and comes apart. Look at a pair of 20 year old Michael Jordan sneakers, they were made by an 7 year old with glue, likely coming apart at the soles right now. I was on a track behind a yellow 996 gt3 with 40k on it (2003 just like mine), his pipes opened up, lost his fluid and his track day and put an aventador into a slide.....he did not replace them because there were no signs (there rarely are) and he played roulette, luckily this guy came with a trailer etc. For comparison I have an 03 with 15k on it and while I was not rushing to drop the engine to do it properly, during the next maintenance session (in this case Pauter rods and goodies) its getting done. Stupid not too if you have to drop the engine


Now go ahead.....think of some mods that will make you do an engine out and then while your in there go ahead the pin them. You;ll never have to worry about it again...

 

Is there a DIY on this ? I'm about to do my clutch, trying to avoid dropping the engine though....

Not a super detailed DIY, but it gives you the basic idea of how to get to the fittings and what to use.

 

I had two different pipes let go, both on track. If you are going to remove the engine I would definitely weld them as opposed to pinning. My thinking is that pinning can prevent a major dumping but can't prevent the glue seals from letting go in the future and causing another leak and may require removing engine again! Welding on the other hand......end of problem. You do need to be selective on who does the welding. Requires a true expert.

 

Thank you !

+1 on the welding
I had Goldcrest do mine and overall it wasn't terrible.
Lost mine on my first ever track day (in a car) on the 2nd lap - so not that fast. Trailered it to GC in Atlanta and bought a $3k shirt that included an engine out coolant system refurbish with all fittings welded.
