I am looking for the Oil Level sensor on a 1990 L98 Convertible. The oil pressure and oil temp gauges are normal as well as the dip stick. I got a printout from the local Chevy Dealer. It showed it on the oil pan close to the drain plug. Not finding it there I noticed the printout said L5 at the top. Went back to the dealer and asked for a printout for the L98. I was told it shows it in the same place. I only discovered this because I needed to remove the center console to fix the after market radio, only to find the Check Engine, ABS, and Low Oil lights had been removed. I cleared the Check Engine Light and moved on to the Low Oil Light. I looked all over the Net and can't find a picture or a video of it's location. I guess I could do what they did, but that wouldn't be fixing the problem. I'll hope someone who has changed the sensor on their C4 L98 can tell me where to find it. I'll continue to look at the ABS problem in the mean time.
