Abc valve block??

[karozza]

I thought the check valves that stop the car dropping when the engine is off are metal-to-metal valves. Surely changing the o-rings isn't going to affect a droopy car?

I agree.

Although many have had positive results by just cleaning & replacing the O rings, there are more factors in play on the small solenoid shut off valves. I have read quite a few cases of unsuccessful attempts by people who have even used the same O rings as fellow forum members.

The metal to metal piston valve must be cleaned thoroughly as one most probably does when doing the cleaning process. But, we are also suggesting the seals on the piston itself are prone to leaking fluid. These, however are quite a challenge to replace!!

We have yet to find a solution!?

so per valve you need two 14 dia and 2 16 dia very special O rings. The dia I show are not the exact dia as they are very special. Took me 3 years to obtain them. For the other 2 solenoids you need 2x 12 dia, 2 x 13dia, 2 x16 dia and 4x 19 dia. (all per valve block.

Hi Kevin, can't pm you as you are a new member, can you advise where to get these O rings please.

Regards
