“My valve cover gasket is leaking on a 1992 Wrangler 4.0 l, 280,000 miles automatic transmission. I went to a Baxter's and they asked if i wanted cork or a true blue something. i went with the cork but was wondering what the main difference is, the price was 10 for the cork and 67 for the blue.”source ↗
