Re: 352: Light Tic Under Light Load, At 2000-3000 RPM

I worked on one cylinder at a time, and used a rope through the spark plug hole to hold the valves in place. Removed the spring, then discarded a .030" spacer, then swapped the old OEM type black seal for a softer, more modern red seal with spring re-enforcer.
With the rope in place, the valves would still drop down about 1/4". I checked each valve carefully for sticking, and they all spun freely and moved up and down easily.

I still like your idea of the special cleaner CD2 Black, and will try to find it locally. It can't hurt.

Since the noise was not there before I swapped the heads, cam, lifters and timing chain, I am thinking its something related to the swap, but am out of ideas as to what.

I am just gonna drive it, but stay local for now. Hopefully it will get bad enough to give itself up, whatever the gremlin is.

Thanks Again,
Joe
