Cosworth yb engine noise. knocking
My 205 blocked saph has what i believe to be piston slap on start up but also once warm it sound like a cam knock but it only makes this noise under load. its definately not the bottom end ie big ends but my concern is that i thought a cam would make a noise all the time and not just under load. any other ideas as to what the noise could be as i cannot buy the bits to fix it unless im sure what the problem is.
thanks
