RED oil light on.

[Kambesama]

On the way home from work the read oil light came on with a nice little beep to to let me know. I knew better than to keep on driving, so I had it towed back to my shop (AAA gives me 3 free tows a year for being a member).
Just added a quart of oil the other day so I was sure the oil level was good. Checked just to verify, oil was indeed full. Lifted it up to check around and saw a trail of fresh oil stemming from the oil pressure switch on the back of the oil filter stand housing. Checked it and was greeted by a connector full of oil. Cleaned the connector and ordered a new pressure switch for like $5 bucks from the parts store and put it in.
Required a 24mm socket. Drove it around and no problems after. Decided to do the full oil change at the same time to be on the safe side.

PS: Broke the connector section of the old switch because I wasn't careful when removing it.

I had that happen to me last year. Chevy cavalier. By the time the oil light came on, it was too late. Scored cylinder walls and toasted bearings. There was no warning. Just going down the freeway, light came on. That was all she wrote.
