Quick EGR Valve Question...

[pulliptears]

Just taken the EGR Valve off the car, an 04 PT Cruiser Diesel after having no end of problems with an engine management light. Thought we had fixed it, seemingly not grrr.

Anyway, can you tell me is this little hole supposed to be there or should there be some kind of bung/Plug in there?

forgot to add, from my research the valve should make a vacuum? Obviously with this hole, it's not making any vacuum.

Which side of the diaphram should have the vacuum? one side of it will require a vent hole so that the diaphram is free to move!

If you suck on the vac pipe and you can't form a vacuum then something is definately knackered! (probably a failed diaphram)

yep, figured that one now lol, thanks.

Looks like the valve is seized closed. Leaving it in soak overnight but I think its a new valve
