mechanic just replaced timing chain and did head work for one valve. Just called him and he said there is ticking noise that will probably just clear up. do i have hydraulic lifters that were dry and now the engine just needs to run for a while?
They have shims to adjust for wear, and the AllData parts list calls them tappets, not cam followers.2001LS8Sport said:Actually, they're technically called "cam followers". And they have to have some sort of hydraulic control. Otherwise, you would have to have your valves adjusted for wear. So yes...I would say he has a plausible answer. They're not dry...they have air in the system. It should bleed out.
