4g63 8v sohc Naturally asperated engine. I need a simple and cheap rebuild kit for this engine. I have seen many rebuild kits including ones used for forklifts. Some have sleeves some don't. I have a what looks like an engine from the 80s. Probably 1st gen. Want to do this as cheap as possible. So best bang for the buck as i want to sell this vehicle but it burns oil like nobody's business and now #1 spark plug is fouling out. Any info would be great. Especially if i can use a forklift engine rebuild kit as they are the cheapest.
