I love driving this car but geez, if it wasn't for this site it would be a ticking time bomb for Joe Driver!
I had some similar lifter noise recently. Was it ticking all the time or just at startup? When the hydraulic lifters bleed down after sitting it seems the pushrods would have SOME slack in them.
It would get worse the hotter the engine got. There was one rocker and push rod with a lot of slack. The rest of the rockers had no slack. There was probably 1/4" - 1/2" play in the rockers and the push rods.
I'm assuming if one cylinder compressed too much liquid, a valve would get bent or something like that. I guess there was too much pressure an a lifter got broken.
