I can't begin to imagine water getting my electronics wet or anything of the sort. I know nobody has faith in the stock pressure sender, but if something ALWAYS runs at one level and then suddenly shoots up one level,
immediately after putting oil into it, and holds that level steady for 15 minutes or so before asploding, then I really want to say my pressure was higher than normal.
Here's the oil flow path on an ISB. It isn't helping me much.
It doesn't say where the oil pressure sensor is, I think it's in the "main oil rifle" on the side of the block? I don't see how a blown oil passage in the gasket wouldn't cause that to drop off. I think that's just not how head-gaskets typically fail.
Provided the oil passage did blow out, then I just have to figure out why the pressure was higher than normal in the first place.
