1991 Mercury Xr2 Bought the car in summer of 2004 Burnt a valve 2nd day seeing how fast this thing will go.Tore head out rebuilt it put it all back together lasted about a year down again think 1# Cylinder ring broke searching for re-ring kit now and info on b6t motors and the best route to go.Well I assumed the worst I let her sit for a whole year.I got the ambition to find out what was wrong.I knew I had oil on the #1 plug and it would foul with in short time.I checked the resistance on the plug wires and that was it.A shorted plug wire.Yeah! New wires and a new battery and she was on the road again. Put up for winter now.
