ticking noise from top of engine
My 2.0L 20V 850 GLT saloon, has been sitting idol for the last 2 years. I am replacing all brake rotors,pads,calipers and handbrake cable. I put a new battery in, and it started first-time. I only ran the engine for a couple of minutes, as there is very little fuel in the tank, but there was a reasonably loud ticking noise from the top of the engine. I suspect it's the valve lifters. Will an engine flush and new quality oil, possibly resolve this noise ?
