Oil pressure sending tq specs
 

Anyone know what the torque specs are for the oil pressure sending unit for the HR motor?

almost nothing...like if you add a little more to it, it'll be zero...

it's 9-12 ft-lbs on the DE

I would say check the factory service manual, LU section I think, but it looks like it's down. The above torque looks right but don't go further into the block than the sensor was originally, should have about half the threads sticking out. If you don't reach the torque before you get to the orginal position of the sensor its fine. The oil on the threads and thread sealant can reduce the torque and it really doesn't need to be that tight to seal.

Id add some mild thread lock and thread it in only hand tight...

bad news:
I broke mine back in the day

good news:
the new sending unit came with a built block
