I can see two separate problems. Crankcase pressure, and low compression on one cylinder.
Crankcase pressure first, because its easier. There should be a breather pipe going from the crankcases to the airbox. Find it, and check it for blockages. If you have trouble with emulsion in the oil (mayonnaise) then that can block up the breather pipe.
Low compression next. The cold header pipe points at low compression, because that cylinder isn't firing as often as it should. You have noise from the valve gear, so that's the place to look first. If you're lucky its just a loose valve adjuster clattering around, and setting the valve clearances will sort it out. If you're unlucky, it could be a broken rocker arm (if it uses them), a knackered camshaft lobe, or something like that.
Of course, it is possible that the problem is just a knackered exhaust gasket, but from the description this does sound like a valve train problem. |
