I recently installed a wet oil pressure gauge to find out why my oil pressure light keeps flashing. When I first start the engine, 20 psi at idle and 30-50 on the freeway. After 3 miles of driving, 5 psi or less at idle and 20 psi on the freeway. I guess about 40-60 psi on the freeway going about 60mph is nice, but it's consistently at 20psi. Driving home on residential streets at 30mph, I get about 15psi reading. I'm running 20w50 oil with viscosity thickener. Should I still drive the van around with the family, or is this oil pressure so low that I should be taking apart the engine? I cleaned the oil relief valve/plunger. Should I stretch that spring out more? 1983.5 Westy with a rebuild about 70K miles ago. -- Craig ===== |
