right ive just fitted a 4x4 inlet plenum fuel rail and pressure reg to my 2wd saff but used the 2wd throttle body etc (dont know if different)

The car runs fine but has got what seems like an air leak now, sort of like a loud whistle it goes away when you rev the car.

i even removed the full thing and put more new gaskets on but still the same

can anybody shed any light please

 

You want to do a pressure test next me thinks.

Pump the hoses with air (compressor and bung in the inlet pipe) Spray soapy water everywhere round the plenum - look for bubbles. Fix leak, Bob's your uncle.

Si

 

why did you change the plenum mate?

 

was told a 4x4 one is better than a 2wd :cool can flow more air etc

 

favorite is the two bolts through the throttle cable bracket leak air

 

cheers ill have a look

 

anyone else?

 

Get yourself a can of WD40, spray all around the joints, when the stuff gets sucked in it will give white smoke, and increase idle a little, just a lot easier.
