hey guyz...need some guidance. its like my '84 Civic's engine has incurred problems like oil consumption, cam broken, block not ok. my mechanic's advising me to replace it. or if i get it mended, he says there are no sure short results. i may keep this car for more than 2-3 years more. so what shall i do? either get it repaired, by replacing head, and put in rings, or replace it. what would be the price of a good used '84 Civic engine or of any higher model? and where would i get it from? Shershah? and how much would it approx. cost for repairing? pistons are ok i guess, no engine overhauling needed, as per my mechanic? plz help.
