Changing Oil Pressure Gauge In A 2.5L

[Butchershop]

Trying to upgrade the cluster and get the oil pressure gauge changed out from a switch to sender.

 

Removed the old one -- which I believe was incorrectly installed. It had a 90 degree brass fitting in the block and the switch screwed into the fitting.

 

Bought the sender as instructed in several threads.

 

But, there's not enough room/clearance to install the larger sender unit. It's just too big.

 

I bought a new smaller switch and have it installed for the time being.

 

Has anyone successfully installed this type sender in a 2.5 4-banger? Or is there another smaller sender I can use? Thanks for the help / advice!

Yes, I've been successful.  Turn the elbow around more upward...  Viola, done.

 

Also, don't wrap the threads on the sender with teflon tape.  The threads need to make good contact with the elbow to ground out through the engine.

It was a tricky process, but IIRC, I didn't have to adjust the elbow on my 2.5 (the elbow is at 90 degrees to the block). There's about 1/4" or less of clearance between the elbow and the block bulges. It was tricky getting it tightened, because I could only get a 1/4 turn with the wrench. It's tedious, but doable.

 

And yes, I installed the fatty sender like in the second picture. Hopefully I won't have to do it again any time soon. :crossfingers:

Agree with not using the teflon tape, but not w/o using a sealer on sensors that ground through the threads. I always use a little non-hardening teflon liquid paste (thread sealer). Will never leak, easy to remove, prevents over-tightening, and no ground problems.
