hey,
i did my first rocker gasket change today, bought the correct gasket and fitted it. wasn't a cheapo one either. i didn't have a torque wrench so i couldn't tighten to 10nm or whatever but searched the net for advice and tightened each 6 nuts to the same tightness by hand.
first i left the engine idling for about 5 mins, all ok. then went for a drive and after 15 mins i stopped after smelling burning rubber. opened the bonnet and oil had pissed out from the back right corner of the rocker cover and the dipstick was empty

i haven't taken the cover off to have a look - will do this tomorrow - but was just wondering if anyone had any idea why this would have happened besides the obvious - torque setting - was pretty sure all nuts were equally tight. also the burning rubber smell is odd.. would have thought a gasket could withheld hot oil as that's it's job!?
