My 97 Volvo 850 glt is great except lately she whines when put into drive and the engine isn't warmed up. I put in Gunk Engine desludger for 5 min idling, then drained and put in 10-30 synthetic and new filter. I also drained the turbo pipe that holds another quart of dirty oil. She still whines when cold in drive, but less loud and for less time, such as 300 yards, about two tenths of a mile. What is causing this? Weak oil pump? Should I be worried?
