What's this

[bilko0795]

Can anyone tell me what this is and can you still get it

[Rusty]

One way valve that takes vacuum to the diff lock. Sits near the strut brace.

Andy where is the best place to get one?

[bilko0795]

Are these easy to come by or only through the stealers

[Rusty]

I'd guess these could be replaced with off the shelf parts, otherwise, anyone breaking a car should have one, unless it's for A/C only?

Has anyone got one of these hanging around i have tried Tps but they can't find it on their system they don't even know what it's for and neither do i, it's a three way valve of some sort two of the stems go to the inlet manifold and one goes to a black plastic pipe that goes up to the bulkhead and through the n/s inner wing through the same hole that water washer bottle filler cap sits. I can't even find a part number for the plastic pipe So can anyone help please.

Here is a picky you can see the plastic pipe at the top of the valve.

It's an AC specific part, protects the vacuum solenoid for the recirc flap on AC cars. It's not listed as a separate part for the ABY - it's sold as a single piece with the vacuum line to the vacuum reservoir and it costs a small fortune.
It's just a check valve though so you could rig up a replacement out of other parts. There is one listed against the V6 engine cars though and it looks the same: 4A0820675A. I have one here from an ABY complete if you need

Just checked with Tps and for a little plastic thing it;s a few quid the reason i'm asking is im having an issue with high revs mainly when it's hot a few of the guys on here yourself included tell me i have a leak on the inlet side i changed all the pipes this year for silicone ones and i damaged the valve by breaking one of the pipes that the hoses fit on you can see it in the pic it's the bottom one, and because the pipes from the inlet also fit onto it via that T piece was wondering if it's causing the high revs due to a leak it that area i don't use the aircon yet another job to get it going seems never ending on these cars. if it's not causing any problems then i will leave alone but if it is i will take you up on your offer just let me know the damage

[mike74]

Until you get it replaced just stick a bolt in the pipe to block it

[Error404]

plug the hose from the inlet manifold and that will stop a boost leak

The factory check valves are expensive, but they are very good quality, I've never known one to fail. With the vacuum line from the inlet manifold to the check valve plugged you won't be able to use the recirc function on the heater / AC control.

You can probably make this work: http://www.ebay.co.uk/itm/Vacuum-Che...item4ae3cb7f37
