I would be lying if I told you that I knew how the block was prepped or if the tech that did the work did in fact apply the right amount of torque too the bolts because I was not there when he did it. With that said, I went to this guy because of his great reputation. I trust him to work on my truck because he's the best in my area. I did some tests of my own before I called him about the truck pissing out of the degas bottle. One being the block tester and the other being the bubble test. I had no bubbles coming out of the degas bottle while the truck was warmed up and idling at 750rpms. When I turned on the high idle switch, I had a small amount of bubbling, prob around 1 bubble every 2 secs. Once I unplugged the turbo, the bubbles stopped. When I had it in for the hg's originally, I had him install a blocked off EGR. With the EGR blocked off and running innovative's tune which turns off the EGR valve, what do my findings mean? Bad EGR, ie. Leaking weld? Or is it a pointless test because the EGR is blocked?
