I do have a question for any of those that know...how can I test the hydraulic cam followers? This may become very obvious once I pull the cams out for the chain/shoe replacement, but just trying to get my info ahead. Will one be squishy and others still firm after sitting for 4 months now during rebuild process?

Symptoms include on very cold (as in under 35 degrees F) and after several days of sitting, I occasionally get a pretty heavy tapping which sounds like the classic lifter sound. I also have a mild tap all the time, even when the heavy tap subsides after about 60 seconds. Last winter, when I had this issue, I did to an oil change with Amsoil 5w/40 European spec which seemed to help, but still get the mild tapping all the time that I'd like to address if I can make it less noisy.

I also get the clattering sound at 1000-1300 rpms on both up and down throttle...I've been told that this is "normal", but still quite annoying on a modern motor.

Any thoughts appreciated!
