I have a 1992 Jeep wrangler with a 2.5L 4 cyl engine with 102,000 miles on it. For the past 6 months I have been experiencing backfires about twice a month. Earlier this week I blew out my 3rd muffler since this started happening.
I don't know if this is related but I have also noticed that I am getting a substantial amount of oil/gas in my airfilter and in the vacumn lines coming from the valve covers. A shop I went to said that I was in need of new rings and that I would be better off with a engine rebuild. Has anyone else experienced these problems? Any suggestions, or should I start saving up now?
