Bailey dump valve- modification
 

Car did not run as it should, I decided the spring on the second piston was too weak. Took valve appart and replaced spring with a stiffer one. Works a treat now. The spring will be found on the thin rod at the vented side of the dumpvalve.
Thought i would post this usefull information for all those running bailey valves that are having running problems.

mmmm i swapped my baileys out for a forge, worked a treat. Now i have a blank..lol far better : )

Baileys = Dustbin fodder.

Not worth their own weight as scrap.

ive got a forge, dont like the sound it makes, personal preferance
I am a machinist and have made from scratch many dumpvalves over the years, based on lots of different designs. What your saying about bailey (no "S") dumpvalves is rubbish, ive never had a problem that i could not sort with a little bit of thought.

Baileys are rubbish, if it takes a machinist and a bit of thought to get a 'new one' to work properly then that sort of confirms it. :lol1:

Its actually a really old one from an rs turbo, forge are rubbish, my car still chatters (compressor surge/stall) with it on, not doing its job IMO
