that would be only the "naked" block and we are speaking about the chains/tensioners/etc here aren't we?
short engine is just block crank and pistons, stripped has no ancillaries
Does anyone have an oil pump assembly or know of s cheap one as I could then fit and test?
If the sumps off surely worth checking mains? Or can't you do that on these? Never stripped one?
Yeah the mains can be checked and done from below, so can the big ends. Pretty sure the thrusts can also be done.
That's what I would do before I even thought of a new pump!
