Hello all again. I would like to know how hard is it to take a 6.0 PSD apart. I taken a bunch of regular cars and trucks apart, but never a diesel truck. I just need to get to the HPOP to see if that stc fitting is broken or cracked and see what ever else is bad up in there. I changed out the oil filter because it would not get any pressure at the icp sensor. I have a mech. gauge hooked there and I charged the batteries real good. spin it over and no press. there or on the oil press. gauge on the dash board. So tomorrow I am going to press. check it with air. and see what happens. So any info would be greatly appreciated. Thanks Mike.
