oil pressure sending switch

[David Teichholtz]

Ok, this is getting nuts. I have run through 4 oil pressure sending switches in the past 2 years, I put the last one in on November 4, it is spewing oil now. I have been buying them at NAPA. Well, I bought 1 and keep getting replacements under the warranty. (and I can replace them now in total darkness in about 10 minutes)

Today I stopped at the Saturn dealer and bought the factory replacement, which was $30+.

Anybody else have this problem?

Nope. Two Saturns (1992 & 1994), > 140,000 on each, still on original senders.

Yep. My Harley popped 'em with yearly regularity. Turned out to be wicked high oil pressure. Check yours, if it's not more or less in the midle range, I'd look long and hard at the pump, relief valve, and such. excessive pressure or just not enough can sometimes pop these silly sensors...

Thanks. I intend to install a 'real' oil pressure gauge soon. I'm not sure what I will do if I do find abnormally high pressure. We are talking a 95 SW1 with 193,000 miles on her. Car still runs fine, I'll probably just keep swapping out the sensors under the warranty. I doubt if I will keep the car much past 300,000 miles or so.

I'm not sure

It might be worth looking into, as it can screw up other things besides sensors. Or at least on paper, it can. Or it might be a plugged up passage. If you're just a bit high, I wouldn't worry though.

Hmmm.

hehehehe. Hey, if it's free...

Of course, the pressure relief might be stuck, and you might be really flooding the crap out of the bearings and all. The big worry is it'll unstuck and get stuck openish, dropping the pressure too low.

I gave up on mine at 256,000, but there were lots of 'issues' creeping in, and dammit, I wanted a new car anyway. Not able to pass the smogger finally condemed it, if it passed, I'd still have it if only so I could save up more money - I hate buying cars on time...
