The copper air horn tube and the braided coolant hoses are now mounted up! Meanwhile, I'm waiting on my last batch of parts to get baked in the oven and I'm waiting on the rubber hose to connect the turbo oil drain pipe to the block and the 45° elbow to connect the 1.25" reservoir coolant...

I mounted up a few of the new brackets with my daughter's help so now the reservoir tank is on for good, the dipstick tube is anchored down and the muffler mount is tied to the block. I also got the air horns bolted on for good with wires connected and I finished forming the copper tube...

Not a big update tonight but I have finished a few more little things. I cut 8" off the bottom of the road draft tube because the first pressure pipe pushed it out over the frame and then I put a hose on it to route between the frame and block again. There was already a hole in the cab sheet...

I guess time will tell and this could be an experiment. If/when it cracks I'll see about getting a bellows section. I'll keep my fingers crossed. That digger project sounds pretty involved. I'm surprised a construction rig would need aftertreatment but then again it is California...

The muffler is hard mounted to the engine, but the chassis connection is not exactly a "hard mount" - it has some rubber isolators that provide a tiny bit of movement (more for vibrations though). That straight section is about 8" long so it's maybe barely long enough for that flex pipe.

Thanks Will and duly noted. So when the truck accelerates will the valve cover torque to the right or torque to the left (driver side)? In your years of wrenching have you ever seen a flex pipe used in a 90° corner?

Thanks! One more round of painting in the booth and I'll have enough parts to bolt everything down for good.

I had to mount up the exhaust to get a measurement for a bracket so I thought I'd throw up a sneak peek pic 😁

I finally tackled the turbo oil drain pipe which I wasn't looking forward to because of compound bends needed to go 10" down, 7.75" inward and 1.75" forward. I took many measurements with squares, plumb bobs, and tape measures. I made a 3d model as best I could and then grabbed a piece of 1"...

The work today involved all sorts of small stuff. To start with i plugged the old air horn bolt holes using some neoprene bonded rubber washers to seal out water & noise (ok, maybe just water...). Now I'm thinking one of these might get removed to run the filter-minder hose up to the turbo...

Not running just yet. I still need to plumb the reservoir tank and build an oil return line before trying to start it.

Manifold is on; torqued to 40 ft-lb w/copper based anti-sieze Turbo with oil line is on; torqued to 32 ft-lb Pressure piping is on; torqued to 65 in-lb (HPS t-bolt spring clamps are rated to 75 in-lb)

@WillWagner was right about pulse manifolds having smaller ports for higher velocities. This mismatch seems a bit much, but the new metal gaskets are what came with the manifold so maybe they're compatible. I typically don't like things that impede airflow like that and it's a challenge to...

The reservoir tank needed a lot of attention internally as there were large amounts of rust scale that came out and continued to come out of it. I pounded the out side with hammers without denting it, then filled it with sharp gravel and shook the crap out of it and then filled it with sand to...

A lot of progress has been made on painting parts and getting them ready to install. I had to reorder paint twice now which is a 1 week delay each time but I've got about 97% of the parts finished 😁 I drilled & tapped a bunch of holes in scrap angle iron to hold my manifold bolts and that...

While I'm waiting for paint to dry i have time to catch up on household stuff and replenish the drained supply of brownie points I've cashed in working on this turbo. The only change I've done recently is to remove the pipe plug and replace it with the oil drain tube fitting.

The plastic strip can be sewn back on. I did mine with a double saddle stitch.

Good idea, Will - I'll take a closer look at that when I get to final assembly

Well, I'm getting down to the nuts & bolts details and I've been painting parts as they're ready. For the high temp parts (manifolds to exhaust stack) I'm using Dura Heat 2.0 and I finally got far enough along to get a start on that. This paint is made for firearm suppressors and it can handle...

Just an anecdotal story here but growing up in the Columbia Basin i would watch farmers harvesting potatoes that had M813s and M814s mixed in with their fleet of KWs, Peterbuilts, and Freightliners. These 6x6s were able to climb the hills that the civvy trucks couldn't (no mud, just 1 to 1.5...
