HI,
My 2.25 petrol 3MB engine has developed a knocking noise once the engine gets warm. It sounds sweet as a nut when cold, but after a few mins theres a rumbling sound when driving, and when idling there is a knocking noise, which speeds up when the throttle is pressed. Power doesnt seem to be any less when on the road, but it doesnt sound too good.
As its currently dark and raining, and my garage is full, I havent actually investigated yet, but does anyone know what it might be? Someone suggested my big ends may have gone, so I suppose its new engine time..or is it?
TIA.
Paul
