After taking a look at vacuum this morning I noticed that the vacuum from the thermal valve is plugged and should go to the EGR...This is an American version btw by comparing the euro to the American vacuum system. The PO must have changed out the instrument cluster with a European version...(beside the point)
Is this an important part of the system? Could it create runnning issues or is it simply something for emissions?
I tapped the plate down just enough on the WUR to bring cold pressure down within range and then removed the pressure regulator from the distributer to possibly lower it's pressure because my system pressure is almost 6 bar. Thought I would remove a washer to get it closer to 5 and noticed the bushing on the bolt head side of the regulator was blown out. This is the second time it had blown a bushing in two days from fuel pressure i guess..not sure...
waiting until the hardware store opens this morning to find the right metric bushing.
Question--Now if i create a hole in the bottom of the WUR to expose the allen bolt, will that adjust my control pressure at operating temperature "warm control pressure"?
Won't the pressure regulator that i just pulled out of the distributor do that by adding or removing washers?
And after making the hole, do I need to seal it off from gas leaking out or just debris getting in?
Good morning by the way
