Question mark because I’m seeking advice from the much more knowledgeable in this here XK forum.
I’ve torn apart my ‘54 XK120 engine and am putting together a list of replacement parts for the rebuild, pondering extent.
The engine is in remarkably good condition, having been run only 20K miles before being parked in 1966 and kept in various dry storage conditions since. It has not been run in all that time. I’m being advised by a mechanical engineer friend with extensive engine rebuilding experience that the cylinder walls need only a hone and the crank and cam journals a light polishing. Timing gear no discernible wear either. All the engine really needs are new gaskets and seals, though replacing the cam and crank bearing shells and the rings are no-brainers.
But what would be advisable otherwise?
The lower chain tensioner is fully functional but definitely primitive - is there a more modern replacement? Ditto the front crank seal. Any advantage to lighter weight, modern pistons, like Mahles? Stick to 8:1 or go to 9? Higher volume oil pump? New valve guides with seals? Other?
This will be a lightly used street machine, maybe a thousand miles or so a year. Looking for reliability more than anything, though a little boost in performance above the SE specs wouldn’t be unwelcome.
What say you, ye wiser ones?
