Oil pressure sensor

**johnfin** · 08-06-2017, 10:45 AM

I bought the standard generic sensor and its too long. Is that a problem. Also what should i put on the threads.

That's not the correct OPSU. Yes it is an issue. You may not be able to thread it down far enough and get leaks.

Anti-seize on the threads.

I know this is an old thread, but what is the size of the special socket tool to install the OPSU. I have read on other posts a 32mm socket....that seems WAY too big...

Not sure I just picked one up from Oreillys for $10

Thanks Scott. I'll try not to bother you so much....looks like you are challenged for time...Oh, and I know about the little wifey feeling ignored because I'm out in my garage paying attention to the other babe in my life...and I thought I was the only one getting razzed all the time for working on her so much!!! Love the build you are doing!

No trouble at all...ask away....

Ok, I saw you mentioned using anti-seize on the OPSU. How about when torquing down the intake manifold bolts to the whopping 89 in/lbs? Thread locker or anti-seize?

***SMWS6TA*** · 01-31-2019, 01:14 PM

That's inch lbs not foot lbs. 89 is about 7 ft lbs

I never use anti-seize on the OPSU, I wouldn't be against some oil on the thread though. Not sure where or why I would say that.

Here's a thread on the tq specs for LS1.

I will file that one. Thanks! So, you wouldn't use anything on the intake manifold bolts?

***SMWS6TA*** · 01-31-2019, 02:42 PM

I haven't. not like you're tq them down that much.

***SMWS6TA*** · 01-31-2019, 02:44 PM

I use anti-seize on plugs, bolts that will see heat cycles, or when you have aluminum and steel combo.

**herculesrider1** · 01-31-2019, 04:39 PM

Thanks man, good information!

***SMWS6TA*** · 02-01-2019, 06:47 AM

I'll also add that starting today I'll be adding it to wheel studs as wheel.

Also if you have rotors that stick to hubs, I've done that too.

**herculesrider1** · 02-01-2019, 07:58 AM

Funny you say that. I had to pound my left rear rotor to get it off. From that point on, I put a light coat of PB Blaster with a rag to keep it from rusting and stay lubed. More good info! Thanks man!

Reference post #2 above. I was wondering if I was going looney as to whether or not you said that! Also, I have seen so many choices on OPSU that say they all fit my 2000 Trans Am on eBay. Which one is the right one? Thanks man!

Not sure what the hell I was thinking that day. I may have been looking at multiply threads that day

I get my sensors from either RockAuto or Oreilly's/Advance, I stay away from AutoZone (Walmart of the parts world)

**herculesrider1** · 02-04-2019, 11:47 AM

Cool, thanks man! No problem, but when you think about it, the OPSU does go through multiple heat cycles, and is mated from steel to aluminum. Anti-seize probably would not hurt. Those are my auto parts stores of choice as well. Thanks again!
