I know what the inline wiper valves look like and where to get one but I am just curious if they are a ball valve (1/4 turn) or are they a needle valve screw type?
Thanks,
Brett

Hey Brett, I don't know about the internals, but I do know my valve only turns about 1/4 turn to open or close.

The A1 used a quarter turn valve whereas the 38 used a needle valve.

Got the answers for both vehicles in one. My error in not specifying that this was in regards to the M38 valve.
Thanks ALL!
