[QUOTE="jpjeep26uk, post: 436664, member: 20690"] OK, I took the valve cover off and my gosh, it was absolutely clotted with filth, literally gunked up with oil and slimy crud and grit. I literally chiselled off a kind of scaly deposit. Took me 90 mins to get it clean. The two holes for the valves were filled with years old goo. I shined it up,put new sealant on and refitted it. I installed a brand new coil ignition and thrashed it down the local highway at 65 to 70 for 15 miles. Not a peep, No flapping, no coughing , no stally crap, no misfires. Really felt a bit quicker and smoother. So for now at least, I think I may have fixed it and will see how long it lasts. Could it be a cruddied up valve cover could cause serious misfiring?
