Hi guys, anyone recommend a MBC that's tried and tested? Looking for a descent bleed valve type for my 940.

I had just a basic BLEED VALVE on my 2 litre Wentworth Turbo 1991 model and it was great with no spiking. Also it ended up on my `88 2.3 940 turbo

The Forge Unos that we fit to out T5`s are not the same type of thing as they are Manual Boost Control Valves which is not the same as a Bleed Valve.

The Bleed Valve does not work on the T5 because of it`s pulses.

ball and spring type are better. as suggested the forge is a good one.

iv got a forge and it works well.

Sorry ...should of explained better.

I am talking V70 T5 the later stronger engine has a Pulse Sensor on the fuel rail as the FPR is down near the steering rack on the chassis.

The older 850 T5 still has the FPR on the rail same as my `98 T4

My Bleed Valve i used on my 940 2 litre will NOT work on my V70 T5 so i had to buy the MBC and all works ok.

I think most enthusiast fit the MBC first so of course it works whatever but i still had my Bleed Valve so of course tried it first before buying anything else and it did not work......hence spending more money
