Message	I'm blowing oil like a mosquito truck so I'm about to pull the motor and put new center housings in the turbos. But I want to make sure that I cover all my bases since I'm at 110K miles. So today I did a leak down test (with the crappy harbor freight tester). Engine warm. Results are as follows: #5=14% #6=17% #3=15% #4=15% #1=19% #2=23% Please note that this tester tests at about 20psi. I have no idea about oil consumption b/c my turbos are eating it. Engine idles pretty smooth with just an occasional miss. But I have a couple of lazy lifters. So is the old girl tired or has she got some life left to her?
