Just posting to say that I have replaced the piston in my diverter valve and serviced it with new o-rings and it has completely transformed the car.
When I opened it up the, o-ring at the top which pushes against the screw top had a slight split in it so was dropping the piston a bit too much during the pen test.
The car has never really run that smoothly, minor fluctuations on idle and never providing smooth constant speed when on boost. I had checked all pipes, coilpacks, IAT, MAF, plugs etc even started replacing crank and knock sensors. I checked the spring in the valve which is still strong and did the pen test a long time ago but never thought to check if boost was passing through between the two larger ports.
This change fixed it and car is much smoother now.
p.s. This might not fix your issues but fully test your valve if you're having boost leak (non-smooth running) related issues
-
Same with me few months ago runs miles better
-
Mine has minor fluctuations on idle ,might have a look at getting a kit.
-
How old was the valve before you serviced it?
-
I bought it second hand so I am not quite sure
-
If you speak nicely to the guys at forge they will send you a service kit out for free :smiley:
-
mine has no leaks at all since the service, i had a brown stain at the bottom where the piston moves up and down. So it is deffo worth it.
-

hi
can you tell me wot the pen test is?
-
Push the valve up with a pen, hold it, put your finger over the top of the diverter valve, pull the pen out and then the valve should stay held in without the pen until you release your finger from the top of the DV.
-
thanks mate I will give that a go

Depends if you have fat fingers or not, lol
Its quite tough pushing it with your finger, Much better with a pen or other instrument that wont scratch the piston.
