Repairing a brake reservac valve

[Durango2k]

...yes it is possible, and it saves you 40 quid.

Simple: put valve in clamps on workbench, tighten gently to hold but but not break it.

Leaver it open using a screwdriver. Yes, some of the vanes clamping it together may partly break of. Thats life.

Take it apart. It's amazing : inside is just a rubber and a thin spring. Clean it all up, and fit the spring on it's small 3 foot stand on the base plate.

Smear the outer edges of both halves with very thin silicone sealant, I use Dirko RED.

Put rubber back in base, gently press it on the silicone beading. It will stay there, the spring is very weak and the rubber has a centre cutout.

Put top back on base, use a small hammer (YES !) and dang it back into its place. It will snap down and be a bit loose. No wonder.

Open the vice and clamp it overnight or so to let the silicone cure.

I gave it a blow / suck test whilst it was in the vice, and it worked 100%.

When I opened it, the spring was a bit disloged, the top/base was loose, the rubber dirty with oxide powder.

Again, 40 Euros saved. And another factory original correct part back in the car.

The gulp valve is fitted to V12 emissions cars with air injection, not your mid sixties XK engine. What part are you talking about?

The 3-way valve on top of the brake reservac....mine is the non-screwed-on version, it sits remote-mounted by about 2 inches on a short hose.

Access is a bit limited under the carbs, remove the air filter (marmelade bin) to get there easier.
