Anyone Pinned Their Own Coolant Lines?
If so....
How did you do that?
What epoxy did you end up using?
I have seen numerous mentions of JB Weld, but wonder if their isn't a better commercial compound for the job.
Red 272 LocTite on a bolt should not be an issue, but my concern is the epoxy breaking down over time and requiring another engine drop. Looking to do this only once.

Yeah. The epoxy isn't responsible for securing pinned fittings, just keeping them from weeping coolant.
The videos I've seen of the OEM epoxy makes it look like that material is crumbling and breaking down, becoming brittle over time and the heat cycling.
However, it looks like the amount of bonding agent Porsche uses is a little scant.
Anyway, JB Weld it is. Thanks!

- remove
- clean (a round wire brush typically used for cleaning before brazing plumbing fittings makes life easier)
- re-install using JB weld
- "pin" using SS fasteners and red loctite.
one fitting "pinned" on backside

Is it a pain to get to before or after the engine is down?
The next problem might be I plan to use a lift table to drop the engine. I don't know if I will be able to do all the work I need with it sitting flat or not.
The one on the top side on the aft of the car is already welded. I'm guessing the rest are either at the bottom aft of the engine or for and aft.

Also, I researched epoxy's pretty heavily before I finally decided to weld min, to my surprise JB Weld is one of the best on the market. The only ones that I could find that were supposed to be better were difficult to get ahold of. I had one of my fittings come lose when I first got my car and I fixed it temporarily with JB Weld and my welder called to bitch at me when he was welding everything up because that was the one fitting that took him forever to get back apart.
