Replaced the seal on my oil level sensor. It was hard like plastic and leaving a puddle about 8-10" diameter holy hell!
I used the vacuum cleaner assist method: using a roll of electrical tape my M18 Milwaukee vacuum fits into the middle and the suction alone holds the tape roll tight.
I had a friend guide the hose just in case the drop in vacuum when I pulled the sensor off would release the roll.
It was terrifying watching the oil try its best to come out 5-8x a second, it's very loud I wish i took video.
I've used the vacuum method on both our N55 motors to change the drain plugs to models with built in valve but the sensor hole is 6-8x as large. I've seen videos of it done but they used a much larger shop vac vs. my battery 2gal model.
I also use the vac when changing oil to remove the oil filter cap. In the past when i didn't i always get oil down the side of the filter housing.
I also changed the o-ring on the coolant hose that goes toward the oil filter housing. It was leaking like crazy.
Tapatalk is not uploading photos at the moment I'll try to add later.
My son left the oil cap off my car and dumped 1/2 qt of oil over half the engine bay and of course enough got onto the serp belt it started to disintegrate. I had a spare but it made a disaster out of the three idler pulleys!
A mini angle grinder with a cup wire wheel and held at just the right angle made fairly quick work of took m taking the mm thick layer of rubber off the three pulleys. At least this time no v belts in every groove of the grooved pulleys.
