What a major pain. Swapped all 8 on my 1031 a little over a year ago. Took about an hour and luckily, none swelled. 4 burned out. 2 out of those 4 failed lost their spade blades in the extraction process. Corrosion or manufacturing defects? These parts are magnetic so corrosion is my guess.

Urethane might be better than vinyl. The original color was brown. These were vinyl which is short for polyvinyl chloride, that same PVC used for plumbing, only it is rendered flexible by addition of an oily substance called plasticizer. Over time, this oil vaporizes, causing hardening and...

This is how the fittings will be assembled to make turbo manifolds. The spaces will be short cuts of pipe, 5/8" or so. The ells coming out of the drawing will be ovalized on the cylinder head to match the individual flanges. This is inverted compared to the stock exhaust manifolds, the...

Glow plugs seal on the chamfer past threads. They do not have tapered threads. Just a tiny bit past finger tight. A 1/4 inch ratchet is more than adequate. Vacuum leak is my guess too. On CUCVs, there is only one vacuum device, the transmission. Trace from the pump to the vacuum...

This thread was started by SteelNinja, specifically about centrifugal type superchargers. Yes, a positive displacement supercharger would be appropriate for certain applications like marine or possibly racing. I have illustrated why they are deleterious to economy and typical road use. I...

How does the Bullet system match boost to fuel rate? If the vehicle is doing road speed with 1/4 throttle yet the boost is 15 PSI, there is a far excess of air which not only consumes 15 HP to produce, it also lowers the efficiency of combustion. And increases oxides of nitrogen. The...

It isn't hardened, quenched or tempered. Low carbon steel. A regular fire should be fine. Watch your wind, the coating shouldn't be PVC but might have a urethane component..that could give rise to HCN..that is hydrogen cyanide..PVC creates COCl, dioxins and other nasties.

The 8 AWG red with black stripe goes to front battery positive and connects to the isolated negative terminal on the passenger side alternator. The 8 AWG solid red goes to the positive terminal of the back battery and connects to the positive terminal of the passenger side alternator. Both are...

Gaskets are in..made a precise drilling template for the turbo exhaust flanges and one for the head flanges. Going to make them all myself.. My truck powers my plasma torch so I have a specific sequence of operations. The TIG welder can run off house 240 volt as stainless is thin. But...

My brake light is also wonky. It is is the dashboard. Next time I get a round tuit

Two types of mechanical driven blowers..positive displacement like Eaton/Roots and centrifugal like Paxton/Procharger. Positive displacement have the problem of part throttle use. Without a bypass or throttle plate, they will reduce economy by placing a large load on the engine crankshaft and...

Do you have a multimeter? Test the regulator block connector on the side of the alternator. The red wire connection needs to be 12 volts on the passenger side, 24 on the drivers side. The red wire is the voltage sense. The big wires.on the back are current wires and at high charge rate...

The book I mentioned has a simple electronic amplifier and conditioner on page 128. It uses voltage comparator to trigger the base of an NPN transistor.

4 pulses per revolution is correct for a 4 stroke V8. The TCI controller might not recognize the factory engine speed sensor driven off the camshaft and oil pump..the factory ESS actually drives the oil pump..the book "The 6.2 Diesel Engine" published by The Diesel Page has an electronic...

Gaskets that were on backorder arrived so I was able to make header flange pattern. Using a spare manifold for a jig instead of a head..lighter and more economical. Each runner will have an individual two bolt flange so I need 8. Three feet of 2.5 inch wide 3/8" stainless will do it with...

Do check all connections. The plastic two pole connector out the side has two wires, one red and one brown. If there is a problem with the red, it could cause the varying output. The red connects to the positive post of the battery it is supposed to charge. This circuit is charge sense and...

Regulator. Assuming all else is correct.

Light turbo charging is within the reliability curve for the 6.2, this is the design intent of the Banks Sidewinder and ATS systems. Both of these companies are still around, the main reason for deprecation of their offerings is age. The system I am designing is based on the operating...

Head gaskets on 6.2 engines are a normal wear item. I'm in the same boat with my 1031. Most cast iron cylinder heads with induction hardened valve seats will crack since the hardened seat is very brittle. Furnace welding is a viable repair method that lasts since it leaves the material in a...

Have you tried removing the drive belt and rotating the pump by hand? Could be a stuck vane or worn bearing. 12 MPG at a mile a minute is about right for 35" tires. I doubt a 6BT would do better than 15 without axle swap even with a .75 overdrive.
