Stalled the engine and now struggling to start and idle and making bad topend noise,as if valves are hitting pistons. Any suggestions?
If it starts then I would leave that possibility to last. I would remove the rocker cover and check the operation of the rockers as one may have slipped sideways and is not directly over a valve stem. t is also possible to check the valve timing with the rocker cover off. Turn the engine clockwise until the rockers on no 1 cylinder start to move watch these rockers and when you see no1 exhaust rocker start to come up then it will be getting close . Keep turning until you see the exhaust rocker stop moving up and the inlet no1 cylinder rocker start to go down. Move the crank back and forth until you get the position of movement either way moves either rocker. This is called valve overlap and if you look at the timing mark on the harmonic balancer pulley then the mark will be almost /on TDC
I would then run the fault codes as there may be other problems that caused the stall situation.
