search for the boost leak. FIXED!
« on: 14 July 2010, 14:27 »
Started stripping the car, bumper off, intercooler off, pipework etc. to find my boost leak, now it is P*SSING down, typical.

Anyway, was hoping to find something, but cant really say I have, now going further to check the operation of the check valves in the system.

I do have however, a reduced diameter dv valve air connection, maybe 1.5mm, could this cause the dv to be restricted in its operation and therefore pass air back into the intake side of the TIP?


What about turning the dv round so the air connection is horizontal? what effect would this have?

Wish I knew,

Couldn't find any signs of leaks, all check valves ok, the only thing that I changed was the DV air connection, I ran 4mm vac tubing all the way getting rid of the 90deg fitting off the top of the DV. The bore of this was about 1.5mm so I guess that was restricting the DV operation.

Renewed loads of hose clips so I suppose it could have been a build up of small leaks.

Wonder what is next????? :laugh:
