Pipe of Agony O-Ring and Securing Ring Prep?

[Bitsyncmaster]

Is the O-ring orange colored and slightly larger than the hole? If so, I've got two of them. Like I said though, they're slightly bigger than the hole in the mixture unit. Is that normal? Should I force them in and find some way to retain them?

Try it. Your pipe should have a good seal (feel snub) when it's installed. Normally you grease the pipe and o-ring but you will need something to hold it in. One guy used a threaded pipe to replace it but you have to be sure you can get the mixture unit in or out.

A local owner has come through with a spare (he's building out a 3.0). If that doesn't work, I can find one at the local volvo junkhouse.

In the mean time, I need to find a new piece of hose that connects the water pump to the return pipe. It's torn on the bottom.

It's never just one thing wrong at a time, is it?

The rubber oring is black.

Does the oring need to be anything special, or just ye-olde-average o-ring that fits in the hole?

Is the brass ring you're referring to present in these pictures? Is it installed correctly? How exactly is that supposed to keep the oring in?

So the O-ring goes inside that, and the tube goes inside that, correct? Does that thing need to be pulled out or somehow bent over the O ring to prevent it from being able to come out?

Yea, the brass ring needs to be completely pulled out and turned around. When put in the other way it will capture the o-ring in the channel. The ID and OD of the o-ring should roughly match the OD of the brass pipe and the ID of the brass ring respectively. Regular o-ring should be fine.

Excellent. So it wasn't lost after all.

For posterity, here are some pictures of the O-ring and brass ring installed correctly.

Thanks for all the advice.

Now you just have to figure out how to put it together with the meter attached to the car and all the fuel hoses/ignition wires in the way!

Hint: if you push down on the air meter plate you can see the hole the pipe fits into.

Did he ever get the thing put back together? Its been a while since we've heard from him.

Yes, once I realized that the copper ring was there, putting it back together was a snap.

I was refering to the RunDMC guy.
