3.6 Pentastar oil pressure sender woes.....

Thanks for the offer on gaskets! I already had a set and not knowing what I needed i ended up getting a new cooler (no body) which came with another set except for the o-ring which was very odd.

The last fix (October 2021), i retrofitted the aluminum housing which required a 14+ cooler, and filter cap as well. For The new housing, you are supposed to swap the sensors and cooler onto the new body. I got it apart this time in just under 20min including dealing with a broke injector plug lock tab. Inspection after disassembly the valley was NOT full, but oil was all over transmission. I was initially guessing the pressure switch spraying that direction. Turns out there was oil between the body and cooler that could only have got there if those gaskets were leaking and some of the bolts were 'loose'. The left side bolt holes are not as deep as the right side and the distance between the screw head (when bottomed out) and body is larger than the cooler flange is ;-/. Bought the next available size shorter bolts (M6 1.0 x 10mm) and reassembled with a dab of loctite.

Might want to check that molded brake booster vacuum line. Mine is about ready to break right where it goes onto the manifold nipple. I probably got too heavy handed it with it when i pulled it off last IDK. Might be heat/age related also considering its right next to the heater Y hose that i replaced 2 years ago. Either way definitely not one that you want to leak.

if someone wants to retrofit the 14+ style housing, i have a nearly new cooler ;-)
