Well, after Adam asked me to have a look at the ‘funny noise’ coming from the engine, I said that I suspected it had spun a big end bearing, probably on number 4 cylinder…
So – was I right?
First job… Engine out!

On a stand:

Sump off – and full of bearing!

As was the oil pickup:

Then it was off with the intermediate section and time to undo the rod bolts:

As suspected – number 4 was the culprit!

Which when picked out…

I suspect that at some point oil surge has occurred and that air has entered the oil pump and ended up at number 4 big end causing the bearing to make contact with the crank and spin.
I might be proved wrong when I strip the old engine, could have been a blocked oil gallery…
We’ll see!
