    I pressurized the turbo today. Less than 10psi enough air was moving out the oil fill tube to blow smoke from a cigarette straight out of the tube and make the end glow brighter. Think I'll start with the turbo.

    Changed the turbo last night and it carries 70 psi oil pressure under full boost. Maybe drops 4-5 psi. Runs better too!
    I got a Borg-Warner turbo from Turbo Supply in Joplin Mo. $900 less than Cat at a KW dealership. Brand new no core. Nice folks too!
