--- spent much of today putzing with the turbo drain line on my Cummins 4BT. The motor mounts I am using (made for a Jeep) don't leave enough room to properly route the drain back into the system so I had to do some chopping and welding.
This doodad comes off the turbo & used to be much longer with a couple of bends in it. I cut and welded it to flow straight down.
THIS doodad used to fit into the engine block (and was a major PITA to remove) as the return tube for the turbo oil. It will now be welded directly into the oil pan once cleaned up a bit. These two pieces will be connected with a section of 7/8" hydraulic line.
The new return point has to fit above the normal "full" mark in order to flow properly and I will position it at one of the X's. Still undecided which.
One concern is simply blocking off the old drain port going into the engine block. I used a screw down type freeze plug that I think will be OK, but still not sure. There should be no real pressure behind it since the crankcase is vented, but still...I may wind up tapping threads and using something more substantial.
Hope everyone is having a good Labor Day holiday and getting some work done. I will be back at it all day Monday.
