After spending ages looking for my oil leak, discovered it's the o/s rocker box gasket. (couldn't find to start with due to oil dripping directly on to the exhaust and burning) Is it a big job? Any advice would be appreciated.

 

not really just a bit fiddly.

Remove your airbox and hosing /bits and bobs so you can get the cover off. undo the bolts , remove, give a good clean and install the new gasket using good quality sealant. also change the D shaped cam bore sealing plugs and spark plug tower sealing gasket while you are there.

Maybe 1 1/2 hours tops.

 

Thanks.
Would you bother doing the N/S one too (It's not leaking though)

 

I'd get something under the car as you may have abit of oil drop down... unless you want a oily driveway...
