we're talking 99 leg l sedan 30th anniv 5-sp with a build date of either 11/98 or 11-19-98 and an EJ221 as shown on dataplate. appears to be a sohc, original mso said 142 hp net, cars101 says it's a 142 hp phase 2, what is the deal here? btw, the owner's manual shows that possible engine types are EJ221 and EJ223. just trying to determine whether it's interference or not. also, the recommended cam belt change interval in the schedule of maintenance is 105,000 miles. much beyond that, this is a fine example of a sube, imho. thanks in advance.
