Low oil level sensor replacement October 16, 2009, 12:18:34 PM So I found my little leak. The Low oil level sensor leaks from the area where it plugs into the harness. It leaks enough that if I let the car sit for a week a get a puddle about 3" in diameter (but I only loose maybe about 1/2 a quart over the 6 months I drive the car). So I'm going to replace it when I do an oil change. My question is how the hell do you unplug the wires from it? I've looked at it and can't figure out how it's done:mullet: Quote Selected
Low oil level sensor replacement Reply #1 – October 16, 2009, 04:02:53 PM The oil pressure sensor, or the low lever sensor? The oil pressure sending unit has a wire that screws on, then there is a peice that unclips so you can then spin off the short wire so you can take the sender off. I thought the low oil level sensor was in the pan? Quote Selected

I just unscrewed the whole thing with out disconecting it when I did the engine swap because I couldn't figure out how to get the wires off then either. They look like they just slip on but they don't want to pull out.... Quote Selected
Low oil level sensor replacement Reply #4 – October 17, 2009, 11:08:13 AM I had the same problem when I rebuilt my engine. Both my old and rebuild had leaky level senders. People say you can buy a plug that fits it, but I couldn't locate one. So I built my own plug. I took it out and disassembled it. It has a couple of c clips and then the guts come out. Then I removed the interior piece with a pair of vice grips. I then cleaned it really good with brake clean and a small brush.I taped a plastic bag blocking off the inside portion of the bolt. Then I filled it with JBWeld.After it was dry I re-installed the sealing ring and torqued it back into the oilpan. So far, its working great. I just removed the wire from the harness so it wont contact ground and indicate low oil. Quote Selected

Due to my car's newly lowered ride height I can swing my camera underneath, but can't reach without ramps or a jack. If you need a better pic lemme know. Quote Selected

When I had the motor out, one of the people who helped me did most of the electrical stuff so I honestly don't know and I've never had to mess with that darn wire. Quote Selected

I might be able to get you a picture later tonight.Well it looks like I just have to pull harder to get it out. I'm hoping a brand new sensor and gasket will fix it. I should have done this when the engine was rebuilt 2 years ago instead of re-using the old sensor :dunce: Quote Selected

Low oil level sensor replacement Reply #12 – October 19, 2009, 09:20:39 PM On closer inspection, I take back my previous statement about yanking it out. It appears that it is held in place as some kind of contact. Mine just popped out easily.When I gutted mine I recall a couple of circlips holding things in. Perhaps this is what keeps it in there. Pic 1 is of the greasy old engine I pulled from the car.Pic 2 is of the contact (that i folded back over and tucked into itself and tucked into the frame).-Dan Quote Selected
Low oil level sensor replacement Reply #13 – October 19, 2009, 09:40:07 PM Since I was wrong and gave bad advice. Here is the correct way to dissassemble your leaky-a$$ level sender.1. Clean it. Break Clean works awesome. 2. Push the rectangular clip up with a flatblade screwdriver and grab it with pliers/another screwdriver.3. Remove the Clip. It looks like this: Quote Selected

I will try to get a picture of my installed potted one.Now remove it from the pan. Disassemble it completely, clean with break clean. And fill it with JB-Weld so it will never leak again.
