Motor has ~217K on it... I'd think that if there was anything to seat it would have sat by now... I also think it could have been rebuilt about 50K ago but I have no idea.
Question is... It seems that the valves were tight. No idea when it was done last. Engine temp was about 45 degrees F and clearances between the rockers & cam was between .1mm and .15mm (.004" and .006") - about the minimum specs.
Is this normal? In 12-15K miles I'm going to replace the eccentrics & such but is it normal for the valves to tighten up rather than wear and loosten?
