So I'm in the midst of replacing my #16 check valve. I'm pulling on the hose that leads to the top of the plenum to remove it and snap, the nipple breaks off. Is that top piece of the plenum replaceable? Or is it part of the plenum, meaning I have to replace the whole thing?

Pics for reference:

It comes off. It twists off. There is a little rubber o-ring under it. Anyone know a part number for this thing?

Hope this helps, you may be in for some more work.

Thanks man. Not looking too good for me, lol.

Anyone have a stock plenum laying around that they wanna get rid of? Or just the top piece?

If it is too much $$$ or you need to drop the engine and pull the windshield to get at the whole assy. Get something like this and thread it in, anchor it with epoxy or the appropriate glue..

Yeah thats also something I thought of. I just wanna be sure that it's gonna hold boost. I don't want to just band-aid it.

This type has a nut to back it up??

Most of the plastic one have ~100+lb burst pressure. Probably high temp is more worry. Stick with brass.

lowest temp Nylon is 95C ~200F

If you had any thoughts of dropping your engine for a bunch of fresh stuff, now's the time. Otherwise I'd be riggin that thing and back on the road. You can get it out by loosening the upper clamps and sliding the rubber sleeves inward.

Time for a new IPD plenum?

Rulez

Usually I look for these opportunities to upgrade, lol. But I'd rather not drop $800+ on that right now.

You can simply lower the motor to get better access.

Atrox

Can you just not source that part?

No part number anywhere on it? Most plastic on these cars has a part number molded into it.
