Reconditioned rods with custom-coated Mahle pistons installed. Caution about Oversized Engine Boring When we build our 6. The stud girdle kit installed utilizing the six outer main bolt holes where cracks are a common problem. While I have heard of people trying this, and even have seen some businesses selling these engines online, I am concerned that the cylinder walls become too thin and that the chance of cracking in the cylinders is too great to do this. There were improvements in both airflow and velocity across the board.
The kit includes stainless braided Teflon hoses, proper fittings and a brand new oil cooler.

On the exhaust side, our biggest gain was a 15% increase in volume and a 26% increase in velocity at. The exhaust valve then opens to expel the exhaust. This is where the fuel enters the engine and we want this area to be as hot as possible so that the fuel will burn faster and more completely. Unfortunately, after about 150,000 miles of happy service, his engine failed.
Ultimately, the block ended up 0. Hopefully, the component photos on the next page help to demonstrate the efficiency advantages gained by this process — it looks even better in real life. Again, the benefits of a stud are the same here as in the bottom end. By starting with a 6. The wide-ranging use of these products in this engine is what really set it apart from others.
Down the road, Ted will be giving us some feedback about the engine and how it performs. They were built to our own proven specifications. We chose to use 1998 6. This amazing process pumps abrasive putty, under high pressure, through each part, following the same path as air flow during engine operation. The squaring of the deck surfaces and the setting of the rod lengths that I discussed earlier, enabled us to achieve a piston protrusion the distance the pistons sit below the deck surface at top dead center within 0. Another key to a smooth-as-possible engine is to make the compression as consistent as possible on all eight cylinders.
It's one that makes a noticeable difference in drivability and power, but its biggest gain is showing noticeably lower exhaust temperature and gains in fuel mileage. These engines don't tend to wear out the cylinder walls, for most all builds a. Also, to make the pistons tougher for this turbocharged application, we coated the domes with a thermal barrier ceramic coating and the skirts with a dry film lubricant coating. The kit will come with everything you need for the installation, as well as step by step instructions to walk you through the install process. As the air transitions from component to component in the intake system and, then, out though the exhaust components, there are irregularities that disrupt and slow the flow through the engine. We wanted to lower our cylinder pressure slightly so we installed.
This time, however, the elimination of the twisting forces should prevent cracks in the cylinders just below the deck surface. This process reduces restrictions and leaves the ports highly polished. It does require a Max E Tork tune to work properly. The pistons were taken to within one-half gram of one another as were the connecting rods on both the small end and big end. We make an extremely heavy duty wrist pin bushing for the 6. As an extra line of defense, we installed bronze coolant passage liners into each cylinder head. Our biggest gain for the intake port was a 28% increase in airflow volume and a 22% increase in velocity at.
We made sure that the deck heights on both sides of the block were as close as possible. In our experience, this slight loss of volume does not sacrifice engine performance. Mostly, I have seen cracks in the main bearing bolt hole areas as shown in the photo below. Efficiency In addressing these issues we were able to utilize several proven modern technologies: specialty engine coatings and extrude honing. In order to prepare the block, we cleaned, magnetic particle inspected magnafluxed for cracks and checked line bore distortion as well as torque plate boring and honing, surfacing the deck to even the deck heights square decked.
Tests are performed at different valve lifts. And if you need any assistance in choosing the right kit for your maintenance needs, just give one of our knowledgeable diesel experts a call or send an email. The first decision we faced was which block we would use as the foundation of our engine. Here at Sinister Diesel, we take all the guesswork out of ordering parts to complete some of the most common maintenance projects and those with the longest parts lists. In our opinion, these early 6. A while back, Ted Rich, of Granite Falls, Washington contacted me about a rather unique 6.
Block with crankshaft, stud girdle, and gear drive fitted. For optimum efficiency, you need to get as much air as possible into and out of the engine as smoothly as possible. I will try to share that information with you. I am hoping that the combination of our intimate knowledge of these engines, a lot of hard work, and some advanced technology have enabled us to produce a truly remarkable replacement engine for his truck. With diesel engines, most of your performance comes from the amount of fuel and air that goes into the engine. Another of the more common problems with both the 6. If you are rebuilding a 6.
Other factors that play a part in keeping the compression ratios consistent were controlled in the remanufacturing process for the cylinder heads. Airflow Efficiency Simplistically, all engines can be viewed as air pumps. By removing weight from the crankshaft we were able to take the unbalanced condition of the rotating assembly down to less than 0. This combination allows for a hotter explosion that pushes the piston down with more force, creating more usable power. It has become clear to us that Mahle pistons are the best available and we use them exclusively. The camshaft core must be returned in good condition, without wear on the gear or damage to the lobes. Throughout the production of the 6.
