Should I have a missing blade, could this be the cause of my rumbling noise as it is spinning uneven.
nope... that's busted out... most definitely what would cause a rumble, as it'll be well out of balance!!
Thanks Paul for that. Anything else I should check while the engines out, got a few seals to replace to try and stop some oil leaks.
If you do the flywheel oil seal, make sure you torque the bolts up properly... 80ft/lbs and make sure you put the pushrod tube retaining wire back in correctly too or you'll notch the pushrods... but other than that, you should be ok
