I replaced bad rubber return lines and now one keeps blowing off. I've found enough here to suspect that there's a blockage. And it may be that metal line running across the front of the motor. There are 3 T's off of that line, and the one closest to the turbo side has been plugged, can one of you guys be so kind as to tell me where that's supposed to go? I will gladly provide pics to anyone who can help. I've been working on this truck for 2 months and this one's got me stuck, I can't find any return line schematics anywhere. I want to get to the mods, please help!!
