Use "Indian Head gasket shellac". Very similar to the stuff Holley carbs
used to use with its carb gaskets. Spray on both sides of new vc gasket,
let dry and wipe all seating surfaces clean of oil before reassembling.
My R60/5 used to
leak in this fashion before I did this. BMW was a bit shy in
using fasteners I guess. How did they expect a "wet" cover to seal with
just 1 main bolt and a couple of "hidden" 10mm
nuts on studs.

I had that Beemer howling at 30 honest HP on a dyno. 38MM Dell'orto
pumpers with oversize valves and ported intake and
exhaust on the heads. Oh yea, shaved about 4 lbs off the flywheel as well.

Last I heard some moron who ended up owning it broke both pistons at the
wrist pin putting crap gas in it. When it pings loud enough to hear it
over the exhaust, you need to
back off until you get some real gas. (Premium or better.)
SIGH!

G'day,
title pretty well says it all. Right hand rocker
cover has small persistent oil leak. Notice half a dozen drops of oil
beneath rocker overnight. No big deal but irritation value is huge.
Have fitted new gasket, helicoil insert in centre stud, new stud with
nut on inside end . Still bloody leaking. Next step is either grin
and bear it or pull
rocker cover again and use some silastic gasket type cement as well as
gasket, or get cover machined flat.
Should've checked if it was warped before but didn't. (sigh) If I get
it machined would I have to get the head machined as well? Only way I
know to check if warped is put a straight edge across it. Old bushy
mechanic I used to know would use a louvre (sheet of glass) out of a
window, seemed to work for him.
Any suggestions gratefully received.
So far have reconditioned carbies, retimed, new plugs and new ignition
trigger (hall effect) device. Now running like a bewdy!! Except for
the irritating bloody leak. Tia.

Mac.
Wait a minute,
Aren't these machines touted for treks through Greater Asia? The Cape?
Tierra del Fuego?
Malibu?
ANWR?

G'day, used Cat gasket cement, rubbery orange type stuff. Cleaned
thoroughly first and put on both sides of gasket, head and rocker
cover. No leaks. Thanks for all responses.
Regards,
Mac
