This is a popular question because parents are concerned about the quality of their children's education. They want to make sure that the materials they purchase will be accepted by the state, public school system or colleges.
Expert: sprinkles08 replied 4 years ago. Hello and welcome to JustAnswer! Yes, the 3.3 and 3.8 are interference engines. They have a timing chain instead of a timing belt though, I've never seen or heard of a timing chain breaking on a 3.3/3.8 and causing any valve damage.sprinkles08, Chrysler/Dodge/Jeep master tech.Category: Dodge.xpert: sprinkles08 replied 4 years ago.

Chrysler started using the then-new Mitsubishi 3.0 liter V6 engine in late 1987, when they had no V6 of their own â indeed, nothing between their modern four-cylinders and their aging V8s.The 2.2 and 2.5 liter engines would only have multiple-port injection when turbocharged; the standard versions made do with a single injector.). The 3.0 liter engine displaced 181 cubic inches, with a bore and stroke of 3.59â x 2.99â and a compression ratio (in 1988) of 8.9:1.
