Hi all, any general advice would be really appreciated iv only ever changed oil and spark plugs before so this is quite a jump for me. i'm rebuilding because of a little smoke on occasional start ups. she was also using more oil than petrol this was clearly some poor gaskets especially the rocker covers. I have removed all the tin were and i'm just about undo the head and then the barrels & pistons. is there any thing i should be looking for measuring etc? before going any further? would you recommend that i split the case? i wasn't planning on it as the Haynes Manuel makes this out to be complex to rebuild. no end float drives fine with no knocking. do i need a new oil cooler? mine has a few bent fins as you can see in the photo how do i remove the bottom tin shown in photo. i'm i OK to remove the bottom pulley? thought best to ask as i don't want to mess with the crank. don't know the exact mileage as she had a recon engine fitted in 88 and current millage reads 114k that mileage could be spread over 2 engines. Thanks Pete.
