I have been doing ALOT of reading today on noisey lifters - i have come to the conclusion that its just 'one of those things' Seems alot of high mileage cars (not just Ford) with hydraulic adjusters get noisey.
Also, just been out to investigate some more with stethoscope - started her up - several 'ticked' for a few seconds, then... nothing! Went for a drive... came back... all quiet.
Must be intermittently sticky or something. Still, will try some 5W 20 soon.
Correct me if im wrong, but didn't Ford release a TSB or whatever recommending 5W 20 instead of the 5W 30?
