Sorry guys to start a new thread for just a quick answer but this is really bugging me
Just went to crank the engine by hand (plugs removed of course) as it's been forced to sit for ages & I just filled auto trans (4.5L & it's full

, I realise torque converter takes a bit but still?). Anyway, when I crank it clockwise, no noise, easily spins. When I crank it
anti-clockwise, a knocking noise from piston I think hitting cylinder walls? Spins just as easy though.....
Is this due to engine operating in a clockwise direction? Sorry but I have never had engine running to check myself since it replaced the ruined one so long ago so, could someone put me in the know pls
