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 |

I've taken 2 of these apart, both from 72's and both most likely original. I swear I found one dished and one domed. euro-spec was flat and it's likely that anyone going to the trouble to rebuild would either reuse what they had or go to the euro spec.
I can't find any good pictures of the pistons from EA0033579 (claimed to come from a 72, I bought the entire engine from the owner who had just crushed the car, I didn't get the serial number from the body) which I recall being dished. here's a shot of the pistons that came out of EA02497. It had ~80k confirmed miles on it when I got it and had been garaged for 15'ish years, so most likely original. |
