Looking for some advise on my 850 mk3 which suffered a gasket failure at the rocker spindle drive side leading to the loss of engine oil. From the photos attached it can be seen that the rocker shaft was basically flush with the gasket. When assembled about 1,500miles ago the rocker spindle was below the depth of the gasket which lead to an oil tight joint until the gasket shimmied out dumping a lot of oil. The bolts were tight when checked and had no signs of leaking. I am suspicious that because I revved the engine to high revs when it was cold perhaps the oil pressure was too high exacerbating the issue. The rear gasket rocker cover was also in the early stages of failing. I positioned the spindles back into the head again and fitted the new gaskets. Durin use it looks like the spindles have moved out slightly until they can’t move anymore, and perhaps the tension created bows the cover slightly although bolts tight, any thoughts?
