I pulled the head off of one side of my 1972 1.7l engine tonight and found dome top pistons/cylinders. They looked to have maybe 50% of life left. It also had the head "gasket" rings. The passenger side retainer wire was broke and the push rods had some wear on them, a scoring about 1/2 in long on all of them about 3/4 up the push rod on the head end. There was almost no noticable cylinder ridge wear. I haven't removed the valves yet but I can tell by looking at the edges of them that the wear is minimal. This may have been rebuilt 20k to 50k miles ago?
Question. Were the stock 1.7l engines dome top pistons? I guess I need to measure bore and stroke to determine what size pistons/cylinders are in this engine? thanks, James |

The W-code engines had domed pistons. Not sure about the EA-code ones.
