Hi all together, yesterday something inexplicable happened to me on my V70R on the maiden ride. I had exactly 118 km behind me since the engine overhaul, until I suddenly noticed in a turn in a place when switching “ha ? the engine is off” ? This happened while rolling without load. I then pushed the car to the nearby hardware store parking lot, towing I refused on principle because the towing for 25 km wanted to have 400 euros. I checked a few things in the parking lot. Spark is yes, timing belt is tight on it, control times was not possible, but with the petrol check came the shock. With drawn nozzles came “Backfire” from the holes of the nozzles on all pots. The cylinder head was the only part that I had to make in foreign power because the valve guides had to be renewed. Can actually only be that the control times are extremely adjusted, I skip almost exclude k I can only say more precisely when I have the car here, but I am already thoughtful as something can be. if now a NW solids ok, but the motor turns cheerfully. So cheerfully that one can mean there is no compression. Is it disgusting the thought however the following: If something has happened with you, how did the piston floors look? I still have the hope that the underbody has got nothing and it may damage itself limited to the head . Greetings
