Hi Makis,
The head was overhauled and new valve guides installed. As well as all springs tested. I had a lifter failure which ruined a cam lobe and scored the journal. This head was than disassembled, cleaned, inspected, and re-installed last winter, with some minor honing to relive the high spots in the scoring. I drove the car frequently throughout the summer of last year putting about 4k on the new lifters and it did not make a sound. All of a sudden this year, the lifter noise developed only when the oil was hot. I tried a heavier oil, did not solve the problem. So I changed the lifter, and the noise did disappear for 2 days of hard driving. Is it possible I got a bad new lifter???
