[Healeys] Loud Metallic Click

[Steve B. Gerow]

Patrick,
I had something similar happen to me. A tremendous loud clattering would come and go. Fortunately I was only 10 mi from home.

In my case it was a dry rocker end - my guess is the oil passage got clogged. When I took the rocker assy off all except one of the rockers had oil in the end cups where the pushrod tubes seat.

I was looking for an excuse to substitute high lift rockers; installed those a year or two ago and haven't had the problem since.

Before doing this, I took the pan off and looked up at the cam lobes, which looked fine.

Maybe you could borrow a rocker assembly and try it out.
