Hi
I took my CB550 K3 out for a ride today, I only did about 15 miles but when I got home I noticed oil trickles down the gearbox casing on the left hand side and also on the gear lever rubber. On closer inspection the cylinder block engine cooling fins also appear to have oil on them. See picture below. So I guess it means a top end gasket change?

Also when the bike was warm and ticking over I also noticed that cylinder 4 was popping every now and then. What could be the cause of this and I guess it is not worth trying to fix it until the head gasket is done?
Many thanks
Dave

Could the leak be from the cam end cap?. But, if it's popping, its probably the head gasket :'( :'( :'(

clean it all off,
using a good cleaner,
then coat with talcom powder,scent of your choice,or even french chalk,
run the engine again,get it hot,see were the oil is coming from,
you should be able to do this on the center stand,it will show easily

But probably the O ring on the oil feed to the cam at the head gasket. Seen quite a few leaks there and all were the LHS.
Sorry!

If this is the source it may correct itself, mine did this whenever it had been stood a few months but cleared up with frequent use.
