Thanks LarryBible, ,,
To start with - I'm not gonna shoot you
Any messenger is welcome in this case.
At which point do I temporarily install the mechanical gauge - at the instrument cluster where the ordinary gauge normaly is attached or at the point where it's connected to the engine??
I understand that there are two "over pressure vents" (don't know the correct term - sorry) as well. I guess that they will open when the pressure reaches a sertain level and that they are mechanical with some kind of spring?! Could they be faulty in any way and cause this pressure problem??
