Thank you very much for taking the time to type that out. Unfortunately it's not what I wanted to hear.

I bought the car in my signature out of a barn disassembled, motor on the foor, etc. Dropped the motor off at my builder the day I bought it, gave him all the sorted/labeled hardware. They SHOULD be there with him. But if for some reason they're not, I don't want to have to wait to a single extra day to drive the car while we source new ones.

I think I could make this with a stud, a tap, and some aluminum collars I have laying around. I'll let you guys know if Im successful.

EDIT: Wow, and the whole housing is surprisingly cheap on eBay. I figured a couple hundred. More like $80. Might buy one as a last resort for insurance.

that sounds like your best approach since they are supplied as a part of the housing.

Just need to make sure that the inlet seats for the pipe unions are not pitted and all threads are good. New pipe copper seals a must (don't use the old ones). I refurbished mine carefully following very small leaks around the housing - tightening up the pipe unions any further asks for trouble. Now dry as anything with no leaks with oil at the hottest temps. Worth taking the time...

tjb616

What copper pipe seals are you referring to?

LM964

Apologies if sounding confusing. If you have also removed the filter housing drain plug, then the copper seal ring for that (and any other drain plug accross the oil system). If you have also removed the pipe connecting unions from the filter housing there will be the copper seals/washers between them and the housing.

The main oil feed pipes should have that unpitted shiny (ball) seat. Making sure they're not corroded is a check too.

My cars have aluminum crush washers, not copper. Not sure that the different metal makes much difference.

LM964

Cheers Rob, Yes, I've seen both used, and from OPC too. Wouldn't like to say what any difference is (if any), unless it's sealing characteristics under high temperatures...

tjb616

Ah yes of course, I bought a dozen or so crush washers in each size when I started the project, but they were all aluminum. Bought new drain plugs too. Thanks!

Here's a silly question, what does everyone use to replace the foam between the oil cooler and the fan?

LM964

There's foam?! New one on me. Have had a couple of cooler out in the past - don't recall seeing any 'foam'. You mean some kind of shroud or other seal?

It is available from Porsche. Prices have doubled since a year ago though.

99% of the 964's out there are running without it.

I used foam rubber weather stripping to seal the gaps between the oil cooler and the fan housing.

Anthony is right on all counts, as usual ! They are numbers 9 and 10 in that link.

I ordered foam from Porsche, it was "New" Old Stock, and was disintegrating in the packaging. It isn't that great.

I plan to use this, which is far superior. I have the Porsche bits as a pattern, but this is far more substantial in terms of dealing with heat and weather. It's even grey, like the factory foam.

I'll pull the bumper and replace it in the next few months. : )

I purchased a bunch of sets. I don't think I paid more than $15 for both at the time. The ones I received were very nice and quite similar to the sound pad used in the engine bay. I would have returned them if they were crumbling again. I believe I still have a new set. The end that meets the bumper has a two sided taper to it.

Now i do recall that the one piece for the side by the oil cooler lines did come looking a bit worse than the others.

tjb616

That's actually not what I was referring to. On the perimeter of the fan housing surface that mates to the perimeter of the oil cooler, there was a thin maybe 5mm x 5mm strip of foam that sits between the surfaces to create a seal.

It can be seen in this picture, although it's deteriorating here as well.
