Well, maybe I finally set a record. A dubious one. I changed the oil pressure sending unit yesterday. Drove 25 miles, all was well, parked car. Started car this morning; right back at 130 PSI. Sheesh.

I sure am glad I used the "cut the access hole" method.

rws.1

that is sickening....
did you clean oil out of the terminal area?
did you torque to 15 ft-lbs?

toxdoc

Yes, I cleaned everything up.

Yes, I torqued to 14.5 ft-lb just for a little "margin of safety." Oh well...

Well, at least it will be replaced for free under warranty! My 1st replacement failed after only a couple months, the only consolation was at least it was free to replace, just my time was unreplaceable.

toxdoc

Thanks for the kind thought, but maybe not. I let it sit around here for at least two months before I put it in, so it might be out of warranty, depending on how long the warranty is.

What method is that? Did you cut a hole through the dash?

REMOVE WIPERS (14mm socket, pull washer hose off too)



REMOVE TRAY (5 plastic rivets. Pull center up, then pull rivet out) Lay upside down ontop of motor.
This is the underneath tray



I cut on an angle so that I can put the plastic piece back on.. sort of like a carving a pumpkin top.



There's the little devil right there. (sorry for the bad pic, but you get the idea)



Using the 1-1/16 deep socket and a long extension, r/r the sensor. This is the new one installed. I used about 2 turns of tape also and didn't over tighten. Just snug it up and when complete, start the car and make sure it doesn't leak.

I used some duct tape and replaced the plastic piece. Looks ugly but you can't see it when the top plastic is put back.

I used a dremel tool instead of the drill....

toxdoc

Yes, that's the method. Currently on something like page 4 of the sticky on this subject, top of the tech section. Good luck!

Thks.

Todd157k is the forum member who posted that, and I got it from him. Thank him!

Todd157k,

Thks...

Many thanx to Todd!!! Now I feel like I copy write infringed him!

It should be at least a year's warranty. My GM sensor was one year. You should be ok, hopefully u kept the reciept too.

toxdoc

Sounds good. Just gotta find that reciept now.

jdmvette

get the standard unit. i replaced mine a while back with it and it's been holding up great. i don't remember the exact part number...do a search.

toxdoc

That's what I used, unfortunately. The Standard Ignition part from Rockauto. Part# PS-308

Oldvetter

Not sure why you put pipe tape on it, mine came with locktite (or some sealant) on the threads.

Todd157k

I put tape on it 'cuz I only tightened it to about 7 ft lbs. The body is THIN aluminum and there's a pcb inside. A slight twist on that board and you're screwed. I kinda laugh at the 14.x lb torque spec.
I'll let everyone know IF/WHEN mine ever fails again.

yes, I also used a dremel for the tight spots however my drill motor ripped through that brittle plastic like a hot knife through butter. I'm a believer in Tim the Tool man Taylor... MORE POWER!!!

This posting needs to be a sticky!!!
Keeps you from taking the top of your engine off.

It's already in the sticky up top titled Sticky: Oil pressure sender relocate
