I had a similar problem with a 96 Dodge pick up V8- At first, the oil pressure will drop slightly, it will then normalize and later down to zero on the highway; repair shop people told me that it had to be the pump due to sludge build up--I knew it couldn't be sludge because the truck was well maintained. After a week and a half of driving the truck around with no oil pressure and no symptoms of engine failure, I finally decided to replace the sensor located behind the engine block. It took me half an hour to replace it and around $20 for the sensor. The guys at Firestone wanted $65/hour to drop the oil pan and replace the oil pump! If you've done good maintenance on your vehicle, look someplace else other than the oil pump- These very seldom fail Jesus -'55 Ply and a whole bunch of other cars ----- Original Message ----- From: Scott H <kneedrager@HOTMAIL.COM> To: <L-FORWARDLOOK@LISTS.PSU.EDU> Sent: Thursday, July 12, 2001 10:29 PM Subject: [FWDLK] Fluctuating oil pressure > This is forwardlook related only to the extentthat if I cant fix this first > thing Fri morning I will not be able to make the trip to Carlisle.
