Our son and grandson visited us the other day ........... just after he drove away his engine stopped and wouldn`t restart.
when I went to look at it I noticed a heavy trail of oil on the road, checking his oil I found his sump empty,
On checking the engine I realised it was spinning to easy and would NOT start. Today I lifted the cam cover. I saw only one cam was turning in response to hitting the starter.
I wonder if anyone could point me in the direction I should start looking for the problem, maybe a pin or keyway has broken.. That wouldn`t explain why the engine `dumped` the oil.
