Naratechwin Posted May 21, 2020 Share Posted May 21, 2020 Hey all, hoping to get some advice on if there are any potential pitfalls in buying a 40 year old new old stock engine (Honda EN2 1335cc 4 Cyl, similar to the EN1 from a second gen Civic). Presumably these things weren't worn in at factory, so should I be able to just use a high-zinc oil on start-up and treat it as if it were rebuilt? Or should I go through the effort to break it down and relube rolling parts (not sure what happens to assembly grease after 40 years..). Soz for the noob question, I don't want to screw up a new engine. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
tortron Posted May 21, 2020 Share Posted May 21, 2020 All the seals will have dried out. Any oil will have drained to the sump, so you may as well whip that off and see what it's like, rocker cover off and see if the cam is dry. Rings are probably stuck, does it turn over?

Naratechwin Posted May 21, 2020 Author Share Posted May 21, 2020 Ahh, fair point. Haven't seen it in person yet, just know of it's existence and have mutual agreement on price. Been garaged in a crate on its side the whole time. Quote Link to comment Share on other sites More sharing options...
