So first question: is there anyway to test the function or "reset" the oil pressure relief valve without removing the oil pump from the block? I think some of the old oil gummed it up (after my oil change, oil pressure has been low at anything other than idle). (On a semi related note, where is the oil pressure sensor located?).
Second (completely unrelated) question: Does anyone know the bolt size/thread pitch for the vacuum assist post on the #6 runner on a mikuni manifold? I think I've got a vac leak in my booster system, and I don't really have time right now to pull the entire thing apart, so I'm willing to just cap it off for now. On the other hand, if feeling the brake peddle pulse while idling with the brake depressed is indicative of something other than a vac leak, can you guys let me know?
Thanks in advance guys.
