Was checking my exhaust leak tonight (my temporary home-made J-pipe gasket finally blew, ordered the real thing). Found another leak, which kinda explained the excessive exhaust noise and loud-ass rattling at mid-to-high RPM's. My wastegate-to-cat pipe has a banged-up metal doughunt hanging on it, and the pipe goes into the flared pipe stub on the cat itself. I ordered an o-ring for that one as well, but I have NO CLUE about the part that's supposed to be holding it on (as in, there's nothing pressing the current seal into the flare on the cat). In other words, if it ever existed, I ain't got it.

Does anyone know what's supposed to be there, and where I can get this... whatever it is?

Ever seen the clamps holding a VW Beetle (old) muffler to the heat exchangers coming off the back cylinders? Same thing!

PCNA has this. Got PET?

20$ plus nuts and bolts... Or 15$ for the beetle one

Is beetle part the same? I'll be at the junkyard this Saturday, i'd be really happy if I grab one there

Or should I stop dreaming and get the new OEM clamp?

Ok, looked some more...

In addition to the actual gasket (which was $13 by itself plus shipping, $21 total), it needs a crush ring (the rattly thingie that I still have, it seems) and both clamps from a 76 911 (I was looking at the wrong part last night). $13 crush ring, $16 for EACH HALF of the clamp, plus fateners and more shipping. All in all, 60$

If I could afford to spend 911 money on a superficial exhaust leak, I'd drive a 911, wouldn't I

Am I even looking at the right parts?

PET doesn't show the right picture - their wastegate attaches to the pipe directly and then goes into the cat, mine goes alongside the cat and enters it in the middle. Theirs doesn't even have my joint. I just crawled the board to get the part number for the o-ring, and deduced that since it was a 911 part, the rest of the hardware was from the same 911 joint as well.

I'd get beetle clamps new if I knew they'd work - are they all the same diameter, or is there a difference? I'm not getting the gaskets till next friday - I think I'll go ahead and pull some junkyard clamps just to see if they'll work, then get new ones for a veedub.

Parts list:

Support washer - 930 123 132 02
Gasket - 930 123 134 04
Clamp halves (2 needed) - 930 123 133 00

You're right, it's $60+ at Sunset not including bolts!

You might measure the OD of the wastegate pipe, and then run over to your VW parts house and measure the ID of the Beetle part. . .it is definately the same setup. See HERE for reference.

I don't know any VW suppliers around here... This is the wrong Washington I'm living in - I haven't seen a classic Beetle in ages

I know Mt Airy yard had some Beetles and a 914, I'll see if they still have any exhaust parts left that might look like that. I'll report tomorrow if it's a match or not.

Ok, got to try the Beetle clamp that I pulled at the junkyard yesterday. It *sorta* fits, but it appears as if the pipe diameter is one size larger. Not by much, but a little bit. I'll have to wait for the gasket to see if the clamp is conforming enough - if not, I'm stuck with a 70$ order and another week of waiting

Those things do, indeed, rot. The clamp set I took was the best one on the whole yard, and even then I managed to break one of the bolts. Another one on a different Beetle just fell apart in my hand.

I did get to see the strangest Fiat... with a tiny little engine stuck in the arse longitudinally - and it was a convertible. Looked like a miniature Spider with an engine on the wrong end. Didn't look all that bad, either.

Nonono, better - I matched it to a picture of an 850 Spider:

Apparently, those have an engine that would barely shame a small motorcycle - 800cc. The motor looked like a little toy, for sure - MG Midget's engine is a giant by comparison.

I wonder what one could squeeze out of that motor, boosted and fuel-injected

Holy krapp

It probably walks all over the MG's of that vintage - more power in a smaller, rear-engined car. From the looks of it, rusts slower, too
