You don't have leverage against the company anymore with your vintage truck. You might be one of 10 customers in a year. They're not going to revise any part of their product to satisfy tens of customers.

If anyone is looking to buy starter bolts I do strongly suggest the ARP option. OEM bolts are no longer available so you're banking on aftermarket. The ARP bolts are made from a stainless steel alloy from Carpenter called Custom 450. Stainless is usually a terrible choice for bolting, hopefully...

Under-tightened belts can also cause bearing failure. Bearings for rotating shafts and stationary housings are clearance fit in the housing. Without sufficient tension the outer races of the bearings can slip or rotate in the housing which causes the system to wear out and fail. Proper belt...

The marine C9 is the most expensive small engine I have ever operated.

You could put it under the bed and then plumb the air intake into the cab.

Whining and buzzing and not going into gear? Have you checked the trans fluid level?

I would run it through the trans cooler first then radiator. The driver's side tank is a constant 180 degrees F as that is when the thermostat opens. There is no flow through that tank during warmup so the trans cooler will not delay the warmup of the engine. If the trans cooler is cooling the...

It still has bubbles. The head shop pinned the cracks between the valves but in one location they did not install the pin under the valve seat. It's outside of the combustion chamber, it only sees exhaust pressure. The engine runs perfectly otherwise and consumes no coolant so I'm just going to...

If you run it without a thermostat watch your temperature. Most heavy duty engines require a thermostat in order to get water to circulate through the radiator.

Use phosphoric acid to flush. It's safer for the engine. You can purchase it as concrete and metal etch at your local hardware store.

M1008? That's the death wobble. The Dana 60 axles are especially prone to it. Kingpins and bushings are worn out. Drop your tire pressure to 30 psi or less and it will go away. This is a test, not a solution.

Good engines will have good compression regardless of temperature. Testing warm is more of a salesman gimmick to convince you to buy a weak engine. Especially in the case of a diesel engine good compression is most important when the engine is cold. Lower cranking speeds due to injectors in the...

The 97+ 6.5 engines had piston cooling jets which is why they required the higher volume pump. I can't say this with confidence but I believe the 93-96 engines had the same pumps as the 6.2 and had turbos too .

Pipe tape is for tapered threads only. You should use the injector washer on the adapter to head. I can't tell what thread you have to mate your gauge to the adapter. It's bottomed out which should never be the case for a tapered thread.

Quality requires specification OR pedigree. Pedigree makes specification easy but can't be relied on forever. Apple engineers were very good at specification to get quality out of their Chinese made phones for example. With that said, we're working with aftermarket parts here. They don't have...

On the subject of glow plugs swelling, for the civy trucks most know not to run the Autolite plugs. They always swell. There are certainly design characteristics that do cause swelling. And don't go calling glow plugs low tech insignificant items. The materials required to make a reliable glow...

If you have a junk glow plug that failed and you keep replacing it with junk glow plugs and they keep failing have you ever considered that it may be the junk glow plugs that are the problem? If you don't want to buy a full set at least put a good plug (Delphi?) in that hole and see if the...

Do like Mercedes and put the batteries in a box somewhere behind the rear seat. Take advantage of your 24V and save a bunch on money on battery cables because you can run a smaller gauge than 12V.

I just rebuilt the front calipers on my M1008. They had a waterline just below the midpoint, they were nearly half full of water. Luckily the bores are hard chromed and the pistons are stainless steel so corrosion was minimal. I put DOT 5 back in because I didn't really want to get into the rear...

Your oil pressure probably is low. It would be wise to check it. If the oil pressure is low, you may consider dropping the pan and rolling in new bearing inserts. If you can tolerate downtime, plastigauge each bearing and mix and match standard inserts with undersized to get the correct...
