Shenker;

Don't take this wrong, but what lesson...? what you are showing looks perfectly normal to me...and is absolutely intended, and actually good design practice and implementation...and not a reason to question parts suppliers...

What I'm seeing on both of those pix is...at rest, and before any compression or preload of the Sealing Rings into their seats both cases! For instance, the visible ridge in the pipe in the first pic will continue into its pocket securely locating and preloading its Sealing Ring. I think you'll find that if you have used the correct Sealing Rings on those pipes (square cross-section, not the taller oval cross-section WaPu to Cyl Head oval Sealing Rings!), there is sufficient play, and the lubing action of sealant allows the pipes to be pushed home the last fraction of an inch, such that you get alignment of the hardware securing the pipes, with a bit of compression preload on the Seals.

Cheers

 

I tend to agree with Ron.

When I rebuilt my B20E, I cleaned up and reused my original pipes with a new water pump (also a GMB pump from IPD). The pipes were very hard to get shoved into place so that they could be bolted on. Lots of silicone grease on the rubber sealing rings helped. The fact that the engine was on an engine stand also made it easier to muscle the pipes into place.

If you have tried fitting your original pipes with new seals into the pump and that is an easy fit then there may be an issue with the new pipes. If the original pipes are also difficult to fit then that may be just the way they are, or it might be a problem with the GMB water pumps. I expect that the demand for vintage Volvo parts is not huge - particularly for the coolant pipes. Multiple vendors list the pipes; but, I am suspicious that they all might come from the same source.

If you want to try and rehabilitate your original pipes, I would not use JB Weld. It may bond; but, epoxy and steel have different expansion rates leading to potential failure of the bond as the pipe heat cycles. I would be more inclined to flow some solder into the corroded areas. If you can find a lead free solder made from tin / copper the galvanic potential is pretty close to mild steel which should make for good compatibility with the pipe. However, I would first be inclined to try shoving a little harder on the new pipes with some silicone grease on the seals.

 

I was so sure I had the o-rings on the right parts that I didn't even consider it.
I had them switched. Thanks Ron.
I'm putting your bracket on this morning too.

 

Yep, I'm very glad I was wrong. Oddly enough, I don't know how well this car held coolant prior, but the rubber o-rings were so deformed I couldn't really tell you if they were in the right spot.

 

Classic Volvo Restoration has always been good to me with my old Amazon project. Glad you got it sorted

 

I tried buying the headrest hardware kit but they emailed me and told me it was backordered and would have them in a few weeks. I checked in every month for 4 months and eventually had to cancel my order. They refunded my money. I hope to have a better experience in the future.

They appear to be a great resource, although I'm pretty sure everything they offer is available somewhere else. Still, having a comprehensive catalog like theirs is really nice.

 

Hey everyone! Excited to be here and share my love for classic cars with all of you. I'm Kost, and I've got a bit of a knack for breathing new life into old vehicles. Whether it's tinkering in the garage or hunting down elusive classic auto parts, I'm always on the lookout for ways to preserve the beauty and history of these iconic rides. Can't wait to swap stories, tips, and maybe even help each other out in our never-ending quest for the perfect vintage piece.
Found that while there's no shortage of classic auto manufacturers like BMW, Mercedes, and Audi, Home - PartsForClassic it's often a bit more challenging to track down parts for Volvo classics. Despite their incredible engineering and timeless design, Volvo parts seem to be a bit more elusive. However, that just adds to the thrill of the hunt, right? I'm curious if anyone else here has had similar experiences or perhaps has some tips for sourcing those hard-to-find Volvo treasures. Let's keep the discussion rolling!

 

I just ordered (again) some parts from Don Thiebault (P1800.com). Many of us know that the P1800 can share the exact same parts as a 122. Sometimes you have to just e-mail, or call Don. I drive by if I am in the area. He's almost local to me, but on occasion he has a part that I can not find anywhere else on the planet (yes).

While not specific to parts, and more product related, yesterday I had an incredibly generous bit of support from Eastwood (product). Those are great people for product, though most people here know that already. -I just like backing people who stand behind their product, and are straight with you. It's often a challenge repiecing together a 50+ year old machine... -We can sometimes make them better than when they left the factory. Here is a source for that help.
