thank you so much!

 

So, a failing cluster causes oil leaks?
or was there something else going on also?

 

I apologize for the confusion! My “leak” was residual oil from the previous rear main seal leak and it was coming out of the bell housing through the gap located bottom center on the inspection plate.

My frequent and alarming oil pressure fluctuations are attributed to the failing cluster

 

Just an FYI, if desired, you should be able to find a good used cluster via car-part.com or eBay... They are pretty easy to swap out. Just make sure that you get one for the correct year truck.

 

I was checking some out on eBay. I’ll definitely explore car-part.com. I’m going to go the mechanical route first to make ensure accurate readings and space out the spending. May replace the cluster if I get tired of hearing the pressure alarm go off

 

I have rarely seen a cluster fail.... I HAVE seen pressure sensors fail.... even new ones.

 

That makes a ton of sense- especially since a duralast sensor was all I could get my hands on when I needed it quick. I’ll dig around and see if I can find an OEM one

 

Any suggestions on brand if I can’t find mopar spec? I’ll call a dealership tomorrow

quick glance shows rock auto has rostra, standard motor, and wve

 

Yep the beauty of most of this stuff is that it's NPT....so Home Depot, Ace, True Value, Lowe's etc!!

 

Did they tell you how they came to that conclusion? Did you possibly do the dash test?
