Oil pressure problems
While driving my oil pressure on my 2007 Chevy Silverado
is 40. When I come to a stop sign it drops to 20. I have
heard twice the lifters clicking. Any suggestions?
first thing to do is service the oil and filter refill with 20-50w..report back here !
Fluctuations on the oil pressure gauge while driving is normal. However, 20 PSI at idle is a bit low especially if you're hearing lifter noise. As Kelly said, change the oil and oil filter. Refill with the manufacturer's recommended weight and type of oil. HTH. -Jim
