Hi all
Well i don't know if that was a waste of money, i took the engine apart as i had tappet noise and nearly replaced every thing lol, took both heads off had them tested cleaned and skimmed, replaced the cam tappets and oil and water pump, flushed every thing out replaced the oil, took the sump off and cleaned it, flushed and cleaned the rocker arms, put it all back together and she fired up straight away and no leaks as of yet, but still get the knocking noise, its still loud when cold and quietens down when warm, But just a thing thats puzzling me and it might be ok and should be there but when i took the sump off, on the back 2 arms as i call them on the crank shaft there where that looked like scrap marks, and i don't know if its this thats catching thats making the noise, if it is what would it be catching on.
