 I am in the process of rebuilding and upgrading my JH engine and was
wondering if someone happens to know when Lotus switched from the old sleeve
style oil relief valve to the newer spring ball check valve style oil relief
valve? I plan to tear down the oil pump and rebuild and check all the
clearances to see if they are within spec, so I know I will find out what
type I have at this point. Just wondering if there was an engine number or
date that determined when the switch took place? Does someone have a picture or drawing of the newer style relief valve? I see the old on in the JH parts book, but no mention of the change to the newer style.
