I HAVE A TICK?
I have a ’91 F150 with a 5.0 in it. It started a tick, So I pulled the valve covers and intake manifold off. I noticed that one rocker arm was very loose and had a collapsed/stuck lifter. I replaced it. I also notices that a couple of the other rocker arms with very very slightly loose. Meaning you could hardly move them. I did not replace those lifters. All the other rockers were extremely tight. I put it back together and it still ticks. My question is… with these hydraulic lifters do you adjust them? It is not an exhaust leak or a spun bearing either. Thanks, Jon.

No adjustment.
How are the push rods, did you check for straightness, or bent pushrods?
Did you use lots of assembly lube?
Did you oil prime before starting engine?
Did you follow proper break in procedure for hydraulic flat tappet lifters?
