2005 town car (4.6L 2v V8, 150k, runs on 5W-30). During cold start (especially in cold weather) knocking noise is heard mostly from one side of the engine for about 30-90 seconds, then quiet. I decided to change lifters (hydraulic lash adjusters) and rocker arms and inspect chain while I will be...
My 98 Gt has a ticking noise when I first start it up, it comes and goes untill it's warmed up. It has been PI swapped. Does this seem like a possible lash adjuster problem or what?
