Well, as in the post title, the saga continues. Migster came round again to look at my cam and gave it and the journal a bloody good clean up.I put everything back together (with lashings of oil) with a plan to warm her up and do several oil changes.
I fired her up (took a few goes) and she ran fine but the oil pressure light remained on. I 'think' I heard knocking after a minute or so but TBH I was too scared to let her run long enough to confirm it.
Now, my thinking is this;- the oil pump is knackered, caused low oil pressure which made the cam journal run dry thus almost seizing the cam (the cap was a bit of a mess!), now that everything is back together and turning, the oil pump is still knackered thus the oil pressure light is staying on.
Sound reasonable or am I missing something simple?
