This engine was designated as the "M20" engine in BMW parlance. These were found in the 325i, 325e, 525i and 525e model cars. No 4 cyl, 8 cyl or big 6 cylinder engines ever had timing belts. All chains. That said, those same engines (the ones with the belts) are among the most long lived and reliable engines ever produced. It is not at all unusual to see one with 250-350 k miles on it and no major rebuild. It was merely a matter of changing the belt and tensioner every 50k miles religiously. The belt change on that car was about a 45 minute job in the hands of an experienced wrench. The first and only one that I did took me about 1 1/2 hours total and I was doing a lot of instruction manual consultation and fumbling around. -- -Fred W Toys for sale, Hey get your toys here: <http://users.adelphia.net/~fredwills/>
