Hi. Have got one end cap off (which I'm assuming is enough to clean shaft) and stripped the shaft. The cap pin is disintegrating a bit and left some swarf behind, so I will not re-use.
I have a split pin that when fitted, is not loose as such, due to the outward tension, though when the split is closed up it will wiggle side to side a bit (I'm guessing about 15 thou. Does it need to be a better fit than this? (going by, quite a bit of oil dribbles out of rocker holes normally, would this drop oil pressure much).
Also, wear on shaft, on all rocker areas, the most is 9 thou. Would this affect efficient valve operation much?. The engine is quiet when running.
Also, eleven of the push rods have a slight flat on the top ball, except one?.
Any help great please.
Cheers, Dave
Ps. On further examination of of shaft/rockers (not cleaned yet), all oil holes appear clear. Could the wear on shaft, also possible wear on the rocker bores cause a loss off oil pressure, causing less oil passage further up the shaft?.
