Can I remove Oil Level Sensor?
 
Can I remove the Oil Level Sensor from the Oil Pan and still make it drivable? Ohio doesn't have Emissions so....

Block it up with a plate because it's leaky?

why not fix the leak, that sensor is there for a reason, its there so if you dont chekc you oil than it tells you your low, and i do not reccomend waiting for the light to come on before chekcing your oil...

I would put a cup under the car and pour it into the engine when full before I'd remove the sensor... seriously, find where it's leaking from and take it from there. Where's it leaking from?

Seriously those sensors by now are fubarred. I can pretty much assure you if your engine ran out of oil it would be scrap before the buzzer went off.

Ditch it if that floats your boat.

Not sure if mine works, but these cars are holding up pretty well in general.

I'm testing mine next time I change the oil. When drained, you should have continuity between the pins on the plug. If it's not working I'll replace it. I'd never disable or remove it. That would be as smart as doing the same to the coolant sensor, which people are constantly asking about. Just CRAZY!

The sensor has nothing to do with emissions, it's for the low oil warning buzzer and light. This is very important! Disabling it is a terribly stupid idea.

Drain the oil, remove the sensor, clean everything thoroughly, replace the gasket and reinstall.

BS. What proof do you have to claim that? The sensors are simple and reliable, and easily checked anyway.

It's a simple switch, it's either going to work or it isn't. As long as the switch is working the warning will go off long before any damage can be done.

I turned my ignition to ON during my last oilchange and the buzzer went off while it was empty. I'd say 21 years isn't half bad for a sensor still working. (86 GXL)

I don't know about that, it's made to go off where you still have a "safe" amount of oil, on MY brand new engine one of the o-rings on the oil filter pedistal block was cut, and spewed oil all over the road, didn't leak on inital start up, but when it got up to operating temp, and higher pressure it leaked, sure enough the buzzer went off, and I was able to pull over, and add oil til I got to my buddies house.

I've tripped mine under heavy sustained cornering before - it still works just fine.

"I check my oil regularly" isn't good enough to save an engine, and that's what the warnings are for. If you're driving down the highway, something flies up and cuts an oil cooler line (or it just fails), the fact that the oil was full when you left your driveway means nothing. This sensor will tell you that your oil level is low BEFORE the engine seizes, giving you enough time to pull over and figure out WTF is wrong.

Same thing with the coolant level sensor. It's gone off on me a few times, and every time was something that failed underway - coolant was full when I left, but something was leaking while I was driving, and midway through the trip, there was no longer a full coolant system. Every time, I was able to pull over and fix the issue before any damage was done.

Keep the sensors there. They prevent annoying rebuilds.

I personally love these topics... they are there all the time. It's a sports car, not a cheap tinker toy. Seriously why do you think these buzzers and sensors are there? It's most certainly not to tell you, "Oop I've shit the bed, now for shit's and giggle's I will annoy you with this insane buzzer I have! "

Slightly off topic, but if you're spending that much time sideways, especially if you regularly trip the oil level sensor, you might want to look into an oil pan baffle. It'll keep the oil from climbing the sides of the pan/block, and ensure the pickup is always getting oil. Nothing like a big glob of air going through the oil system at high RPM to ruin your day.

None. Only the fact that every RX I've had has come complete with a faulty one........My bad. :dunno:

It's probably leaking because the sealing o-ring has dried out. It's fairly common as it gets baked with hot oil over a 20 year period, but it's an easy fix. Just pull the sender and bring it to your local o-ring store (hydraulic shop, fastener store, etc.) and pick up a replacement that fits in place of the stock ring (which will look triangular at this point but it should be round). Now reinstall the sensor, using a bit of gasket goo around the mating flange for good measure.

The sensor is there to warn you that you are getting low on oil. Removal would eliminate this safety feature. In the event of something like an oil cooler line failure, this sensor is the only thing that will warn you before the engine seizes.

Well, I was just kind of wondering cause I'll definately fix the leak in it. Just wanted to get more info about it before I go further.

I can't find a leak anywhere else
