update today:
engine after 268 000km:
cylinderhead; pretty good, valve guides are worn, valve seats on the exhaust side are bit hammered. It's off to the machine shop allong with my engine expert, no flowing will be performed as my head is a real treat, inlet ports are bigger than de ports of my inletcollector, so will need some modifying on that side.
block: skuff in cylinder 2, no damage to pistons, needs new bearings etc for sure, crank is supernice, inside of the engine looks superfine. Just needs to be honed, look pretty good. Measured everything and were within wearmargin, so great!
All in all a great day!
