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...

This weekend was all about freshening up the paint on the RH side of the engine. Before I always thought my engine had OD Green and Cummins industrial tan parts added to a charcoal gray engine, but after degreasing and pressure washing it I'm convinced that the entire engine is still gray...

The M809 series TMs call for 130-167 lb-ft

My neighbor said he put 2 million miles on his small cam but he said you have to be smart with your foot to keep from burning a piston.

To change the direction of the tank's outlet pipe i sourced a 1 1/4" mandrel bent 90° stainless elbow with rolled beads from a fuel filler neck company and then shortened one leg to allow it to fit between the tank pipe and the engine block. The TIG guy said that "walking the cup" was...

The relocation of the surge/reservoir tank to the firewall has been an ongoing, slow but painful sort of project. Originally it mounted to the exhaust manifold bolts so I wanted to keep its install height close to that in case it affects its function. I clamped a corner square to the manifold...
