I purchased a new 2003 TLS a few weeks ago. I also purchased a Helms service manual. I thought that the service manual would contain info such as engine block and head metal meteral, crank material, info describing detailed workings of the Dual Stage Intake Manafold, the Variable Valve Timing and Lift Electronic Control and etc., but that is not the case. Does anyone have that info or do you know of a web site that has that info?

Thanks,
Don Moore
