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.

How long would that be?

Only put 129K on the clock—so far.

If you are pinning - all you need is some red Loctite. will work just fine

So, JB Weld must be superior to the epoxy that Porsche factory uses? Isn't that a hoot?

Hi Marv,

If you are pinning these, you don't need to glue them as well. I just used 3mm bolts with red Loctite.

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.
Good to go

Thanks for the picture. Good to know where to drill and tap the fasteners so they don't interfere with something else.

there are 8 total fittings. 2 at the oil cooler can be a major pain to get to

I plan on dropping the engine.

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.

all are on top of the motor. sitting on a table is fine. you will find it easier to remove the intake setup to get to some of the fittings

+1, taking off the upper intakes, or at least the center sections between the uppers makes getting that oil cooler out much much easier. Once it's out from the car it's not a bad job.

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.
