N75 Valves

Yup, no leaks. Only place air comes out is the oil filler.

Would a slowly failing MAF cause such issues?

My g/s is down on what it should be as well.

It can do, if it's on its way out things will slowly be getting worse, you tried cleaning the contacts on MAF and cleaning the sensor as well?

[Yohan]

Nope, haven't tackled the MAF yet as it's 2 months old so thought it couldn't be that.

Is cleaning the sensors recommended?

A friend is going to let me borrow his at the weekend so hopefully that will rule the MAF out.

I remember on his LCR though when it went duff it just lost more and more power but never threw a fault code.

    you should be able to blow thru the centre (boot in) port of the n75 and it should exit the long (tip) port.
    yours sounds blocked which is'nt good.. but this should create uncontrolled boost if when you blow into the ports nothing comes out..? "

Can anybody else confirm whether they can blow through the bottom of their N75 valve and feel the air exiting from the TIP port?

I dont really do blow jobs.......

I'll see if I can give it a go tonight as I need to plumb the MBC in for up up up boost.

right I have my N75 here...

long pipe that goes to TIP - can't suck or blow through it

short pipes - can blow suck through these pipes

Same result, I can blow and suck through both short pipes, but nothing through long one. When you blow through either short ones it blows out the other short one.
