Thanks for the info, I guess the compression test would tell for
sure?

I plan to put about 500 to 800 miles a week on it for the rest of the
spring, summer, and into the fall. Unless something fails completely,
I will probably run it up to timing belt replacement and then change
out everything.

Is rebuilding or replacing the block and head generally recommended??
