Engine Mechanical problem
1990 Nissan Truck Four Wheel Drive Manual

I am looking at a older model nissan, I am really not sure of the model or mileage, but the timing chain broke and I was wondering if it messed up the valves when it done it because I heard that if it breaks it always messes up the valves and how much trouble would that be to fix.

Hi there,

I am presuming that this is an over head cam engine, if so you will be looking at bent valves, this is not normally the end of the world, but you will have to get the head off to make sure that there is no other damage, I would be very surprised if there was a damaged piston, you will have to look at replacing chain, gears and guides as well.
