Coming home from work last week I laboured the engine slightly on my 1500 Spit on heard a slight bottom end knock from the engine. ( I only heard it once)The car runs fine, nice and cool and the oil light doesn't flicker so it seemed o.k.I changed the oil last weekend and then started it up and it sounded fine. I then got in the pit underneath it to check for any drips and when my head was near the sump, I could hear a knocking sound inside the bottom of the engine.

I dropped the sump and checked the big end bearings and the mains. Both has just run their coatings so I'll just replace the shells. The crank seemed fine
