[W126 Coupe] what's that engine part?

[webjamin at att.net]

Tom & Jonathan,

Thanks for the reply. I had the car in for a funny sound and it turned out to be the tensioner going bad. When I had my mechanic replaced it, I also asked him to check the timing chain. According to him, the chain had already been replaced and all looked good. I'll pick up a gasket this week....thanks!

Rear rotors, "easy as pie"? Does that mean that all I have to do is remove the caliper, rotor center bolt, socket head screw, and pull it off? BTW, I did my fronts last year and did do the bearings at that time.

thanks again, Lance
