Head Studs vs Head Bolts

This is a question often asked. Why should I install head studs when replacing the head gasket on my truck? Why can’t I just use the factory style head bolt?

In a diesel application there is a very high cylinder pressure which is very hard on head gaskets. The factory style Head Bolt is a torque to yield bolt. This means that you torque the bolt to a specific torque and then in most cases do a 90 degree rotation on the bolt which will put it in its optimum stretch point. This will then create the maximum clamping force of that fastener.

Shop for Head Studs


We have found, over the years of working on diesel trucks, that when you add horsepower with things like chips, programmers, injectors, and larger (or multiple) turbochargers you are at a higher risk of creating that high cylinder pressure lower in the RPM range resulting in a blown head gasket.

The design behind a head stud is to have a fastener that does not stretch. This is done by using a high tensile strength alloy and a stud rather than a bolt. The stud allows for a fine thread nut on the top which will result in a more precise torque of the head.

We highly recommend that whenever you are looking at replacing your head gaskets that you add the insurance of installing a fastener that will not stretch and put you back in the same position of replacing another head gasket.

At East Coast Diesel we sell a complete line of the ARP Fasteners. This includes Head Stud kits, Main Stud Kits as well as Rod bolts and many other applications. Let’s face it, who wants to take power away from their truck in order to keep it from blowing a head gasket, hence the reason to install head studs. Call and talk with our knowledgeable staff and allow them to help you select to correct fastener for your application!!!


6.0L Ford Injectors|Genuine Motorcraft vs. Aftermarket Reman

We all know that the Ford 6.0L Ford Powerstroke Diesel has had all kinds of issues; Blown Head Gaskets, Plugged Oil Coolers, Fried FICM’s, Cracked EGR Coolers, and the list goes on and on. There are all kinds of theories out there as to why these injectors fail and what can be done to make them last longer. There are additives, special oils, and so on. If you have tried all these magic formulas and your injectors are just too far gone to save them, you’ve likely decided you are going to go ahead and buy injectors for your truck. Now the question is which brand of injectors do you buy? You research, and there again you have all kinds of options, suggestions and theories.

Shop 6.0L Injectors


We’d like to help you address the issue of having to replace injectors in your 6.0L. At East Coast Diesel we believe that the best injector you can purchase for your 6.0L is the Genuine Motorcraft Injector. This injector is the only injector that has a New Spool Valve. The spool valve is in the top of the injector and is the number one reason for your truck to have a hard starting issue and a rough idle after startup. This spool valve actuates side to side at a very high rate of speed with a very tight tolerance allowing the high pressure oil to move through the injector causing the injector to fire. With lack of service, such as a good quality oil change on regular basis, these spool valves will wear, causing them to stick and hence the term injector stickage.

Aftermarket rebuilders will reman the 6.0L injector for as low a cost as possible. This will often result in the spool valves being reconditioned and or tested and reused. With the spool valve being the number one reason for 6.0L injector failure, it would be a mistake to purchase an injector that has anything less than the a brand new spool valve!

Cold Weather Making Your 7.3L & 6.0L Powerstroke Diesel Heui Injectors Fail?

The problem

If your Powerstroke is having hard start issues now that that the cold weather has hit, you may have failing Fuel Injectors. Failure in a HEUI (hydraulic electronic unit injector) style fuel injectors, which are used in the 7.3L & 6.0L Powerstroke motors, are common and often will start showing up once the cold weather hits. The failure of injectors is due to common wear and tear, but can also be amplified by poor maintenance and bad fuel. The HEUI Style Injector uses Engine oil to fire the Injector and therefore not changing oil on a regular bases or not using good quality engine oil can shorten the life of your injectors as well as running poor quality fuel. When colder temperatures hit, the oil thickens running through these injectors, which leads to them not firing correctly, in turn causing a hard start or even a no start. If your only option to start your truck once cold weather hits is plugging it in, then you need replacement Fuel Injectors.

The Solution

Full Force Diesel Remanufactures the 7.3L Injector and puts an “18 Month Warranty” on their Injectors. These Injectors are completely remanufactured to the highest standards. Full Force Diesel completely disassembled and rebuilt ground up to include only the finest parts. These parts include all NEW Plungers and Barrels, NEW Nozzles & Springs. Full Force Diesel also installs all NEW O-Rings and Crush Washer. To top all of this off the injectors are then Flow Tested and shipped in sets of 8 Injectors to ensure a less than 1% difference in the flow rates between the set. You can be sure that if you find yourself needing injectors, Full Force Diesel has you covered. You will not buy a Higher Quality Injector at a cheaper price and still have a “18 Month Warranty”.

Why Do We Recommend Carrillo Rods?


It all comes down to time-tested & trusted quality and function wrapped together for a great price.


Carrillo goes above & beyond by having their rods heat validated, by the supplier and by an independent metallurgist who confirms the desired physical and chemical properties of steel. Each lot of bolts are sample tested destructively for both ultimate tensile strength as well as levels of fatigue.

When it comes to rods, Carrillo uses proprietary chrome, moly, nickel, and vanadium alloy (meets all VAR, vacuum arc re-melt ASTM standards).

All heat treat processes are done by a mar-aged operation, resulting in UTS of 195,000 with a yield of 182,000 – this maintains the critical elements of low notch-sensitivity and ductility.

All Carrillo billet connecting rods are manufactured from an oversized forging which results in a proper grainflow – this process removes any potential inclusions or surface conversions generated by the forging process. Carrillo’s CNC machines validate dimensional integrity by probing. At least twice during the production process each part is magnafluxed. Each piece is also Rockwell tested to validate the heat treat procedure. Finally, to complete the part, a final shotpeen operation is done.

Carrillo has been in the custom rod business since 1963 and has provided custom & prototype rods to every major automotive & motorcycle venue. So, they know their stuff.

AirDog® II Demand Flow 165


AirDog Demand FlowAirDog® II Demand Flow 165 (DF165)

AirDog® II is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water. As it passes through the AirDog® II Unit it will separate the Air/Vapor from the fuel and Filter the Fuel to a 2 Micron Level before supplying your engine will clean, air free fuel. One of the Key Features that we at ECD like about this unit is the fact that it will circulate the unused fuel within the filter base versus returning the fuel back to the tank like the AirDog® Original and other competitors pumps. With this feature you are only filtering and separating the Air/Vapor off the fuel once, instead of returning the fuel back to the tank. Continue reading
