Hi all, thank you for all the posts and information on the site. I have been working through some issues on my 2001 3500 G-van and I am making progress. I built a turbo master today and am hoping for reduced turbo lag and the ability to take of the vacuum pump. What instigated this was a super loud racket coming from the lower front right of the engine. I put a 'stethoscope' on the items in that area and the whack, whack, whack seemed to be coming from the pump. It did not sound like bearing death march. Odd though, 1,500 miles later on the cross country trip, the noise stopped and the boost came back. I am still concerned about the pump, and in particular it seizing up. So, if my turbo master works I want to take it off, but I have found on my van that it goes to the HVAC system and with the vacuum feed line to that system remove, I don't have any HVAC controls.
Is this just my van where the vacuum controls the HVAC?
Have any of you others that removed the vacuum pump got around this issue with something like a 12 V vac pump?
Thanks for any clarification on this...
