Looking over the engine (more accurately, staring in distain at the clogged cat, but it was in the general area...) a few days ago I noticed that there was oil on the underside of the oil pressure sender (http://www.delorean.com/store/p-6227...sor-light.aspx) on the driver's side of the engine. I tightened it up about a turn and cleaned it off, but when I checked it after having it running for a few minutes (to shuffle the cars around to get the car into the garage to work on it...) it again had oil under it.
Is there a torque spec for the pressure sender? It seemed like I could tighten it more, but I didn't want to damage it or the block. If I get a replacement sensor (and crush washer), can it be replaced without draining the oil (or more accurately, without making a massive mess if I don't drain the oil...)?
Thanks!
