I have a 94 850 Turbo with about 150,000 miles. All of its life it has had synthetic oil (Mobil 1) changed at every 3,000 miles by me and I use Volvo filters. It also uses no measurable amount of oil. The engine looks very clean from what I can see on the inside, but it has what I am assuming to be a lifter pecking at idle.
It pecks for about 5 seconds and stops for about 15, then repeats over and over.
Is this something that I need to be worried about? The car runs fine, I just hate pecking engines. Are there adjustments, or are they hydraulic lifters and I have to live with the pecking?
Thank you in advance for any info.
James
