Torque value for oil pressure switch and adaptor

[fallingat120mph]

86' Coupe/3.2

Have these now (oil pressure adapter and oil pressure switch):

But haven't received my Bentley yet...just wanted to verify torque values...

Is it 26 for the adapter and 15 for the switch? Sounds like it's easy to over-tighten...advice/experience welcome.

Thanks in advance!

I didn’t do the adapter but I recently did my switch and I tightened it to 11 ft lbs per recommendation of other pelicans. It felt mighty tight for its size and I wouldn’t have wanted to take it any tighter. That fixed my leak…

Found this thread this morning over coffee:

Oil Pressure Switch Fitting Torque


26 seems fine for the adapter and maybe between 11 and 13 for the switch itself. Can always tighten more later on...


Appreciate the feedback airkewldfan.

On things like that, I go just tight enough that it doesn't leak.

Tighten the oil pressure sender into the block off the engine in a vice, then snug that block to the case with the banjo bolt. If you tighten it held by the banjo bolt you risk snapping the case....
Ah your doing the switch, input my adapter on and torqued it, the switch is loose fit untill I hookup oil feed line for the turbo .

I'm with Pete. Torque is important in some applications, like rod or head or case or cylinder bolt, or flywheel bolts. These bolts need to be stretched far enough that the residual tension exceeds the forces trying to move the bolted surfaces apart.

Otherwise, absent some special vibration or other condition, getting things snug is good enough. The larger the bolt diameter, the more force to get things snug. The tools you use can help you - longer handles versus shorter handles. A hollow bolt (like a pressure sensor) you wouldn't want to use a 16" Crescent on. You just need to crush the washer a bit so you don't get a leak, and you can add a half turn more if you see a little leak developing.

Thanks guys...

Appreciate it.
