Not at all, strange how its decided to come loose over a year after i put it on.
Dash is coming out tonight anyway, and i'll see if i can clean up the crank a little.
Was all new bolts matt, i made sure of that.
I dont think it would have done any damage tbh, but im tempted to drop the pan just to have a nose about.
I'll be quite subtle dont worry and not chav.
