Towing for 2hrs or so. Normal temps, 160-170. Glance at oil pressure gauge and it is only halfway up. Typically cruises at 40 or slightly less.
Hop out, little low on oil. Top off, good to go.
Top off when leaving Rausch, not very low.
2hrs or so in, same thing. This time I pay attention and load/RPMs seem to decrease pressure. Coming to a stop bumps it back to 40.
Check level, not low at all. Top off a little anyway and good to go again.
25min from home, does it again. Still doesn't seem low. Fucked off, I dump some in since it remedied it before. Fine again.
Get home, driver's side of block is glazed with oil and pumpkin is dripping probably every 5 seconds. Probably left a 4"x4" puddle saturated on cardboard along with lots of other little dribbles.
Random Googling of forums says these pressure sensors can kinda suck sometimes.
I spend some time with my sweet free HF light I stole from Chad and find the oil pressure sender has fresh looking oil around it. Think this could be great. Wipe it off clean and surrounding areas. Start up and there is a run coming down about 1" to the left of the pressure sensor. 99% sure it's the tappet cover.
$20 for mech gauge, $20 for pressure sensor. Going to plumb the gauge into that port and see what she says. People report wildy different readings from stock gauge and mechanical gauge. Kinda like stock is more like an idiot light than a true reading.
