Main Cap Stud Kit Available for LS Engines: Part # 1000098

PRW Now Carries a Heavy Duty Main Cap Stud Kit for GM LS Series Engines!

We’re excited to announce our new Main Cap Stud Kit for your LS Engine.  Available for 4.8, 5.3, 5.7, and 6.0L LS Based Engines from 1997-2015 with a 6 Bolt Main.

If you want to improve the life of your engine block, upgrade your stock bolts to stronger, more capable studs.

If you’re upgrading  with higher horsepower parts, the higher cylinder pressures may cause the stock bolts to stretch which is knows as main cap “walk”.  This can create high vibration causing damage to contacted surfaces.  What can happen is the loosening of other parts such as main bearings and eventually oil pressure loss.

Our main cap upgrade replaces the stock bolts to high performance studs.  PRW uses premium grade Custom 4150 Steel rated at “aircraft” quality. Our studs are then specially heat-treated to 180,000 psi. This heat treating procedure allows for total heat penetration which results in a stronger, more superior stud compared to lesser quality studs from other manufacturers.

COVID-19 (Coronavirus) Update for PRW Customers

COVID-19 and our commitment to you

Hours of Operation (shipping included):  Monday – Friday 7:00am-4:00pm

 

To Our Valued Dealers, Distributors, Resellers and Consumers,

In response to the virus, we’ve implemented updated best practices in our workplace to help ensure the health and safety of our employees and customers. PRW Industries is also closely monitoring the COVID-19 situation and working tirelessly to serve the needs of our customers and individuals who are quickly adapting to new ways of life as we all pull together to curtail this outbreak.

Putting our Employees and Customers First
In accordance with California’s recent statewide stay-at-home order, some employees in our Los Angeles area headquarters are now working from home. We have temporarily limited on-site business operations to essential staff in our office and warehouse to ensure fulfilment and delivery of customer orders with minimal interruption. These essential employees adhere to recommended hygiene and social distancing practices, and janitorial services have been enhanced to preserve a clean, healthy work environment.
These precautions are designed to ensure customer orders are picked, packed and shipped by healthy employees. Once a package leaves our warehouse, it’s entrusted to one of our shipping partners. A large percentage of these orders are delivered via UPS or the US Postal Service, both of which are taking steps to ensure the health of their employees and safe parcel delivery. UPS has published its COVID-19 response and the USPS is following guidelines published by the CDC. PRW and its overland fulfilment partners are pulling together to deliver the highest, healthiest level of service to our customers.

Technical Support & Customer Service
PRW will continue to provide Customer Service and Technical Support via telephone on a limited basis. It may become necessary to return telephone calls at specific times of day to fulfill the needs of our customers and consumers. If the Customer Service and/or Tech Team is working from home, we have made arrangements for telephone transfers to respond to incoming calls. Please be patient, since inventory feeds may not be readily at-hand under those circumstances. Dealers, distributors, retailers, and resellers may wish to subscribe to our daily inventory feed. That service that is available in digital format at 4:00am PDT/PST every morning to better monitor product availability and keep your customers informed accordingly.

Commitment to Fair Prices
PRW is committed to fair pricing. Tariffs and other supply chain fluctuations, industry adjustments, and changes in consumer demand will no doubt place pressure on warehouse distribution and the e-commerce system as a whole. The management and staff at PRW Industries are especially grateful to you – our loyal customers – for helping to ensure best business practices, especially during trying times like these.

The Future
As the COVID-19 situation remains fluid, PRW Industries is committed to helping customers manage through these difficult times. Our company will continue to monitor and respond to federal, state and local health authorities to protect our employees and serve our customers safely, and with minimal disruption.

 

Respectfully,
Bill McGloghlon
President, PRW Industries

Solving Ford 6.0L V8 Diesel Head Gasket Failures

Solving Ford 6.0L V8 Diesel Head Gasket Failures

 

The Ford 6.0 L diesel V8 engine was introduced in the mid-2003 production year, and ended in 2007 for most applications where it was offered.  It has been an engine with a reputation for problems through its relatively short production life, although as the engine received upgrades, and proper repairs, it became more reliable.    One major problem has centered on cylinder head gasket failures.

One of the major culprits here was the factory TTY (Torque to Yield) head bolts.  The TTY bolts are considered to be ‘one-time use’ products, and if they are removed from the engine for any reason, they must be replaced with new fasteners.  This is true in any application where TTY bolts are used.

 

The gasket failures could be caused by re-use of TTY fasteners, but also can be caused by failure of the oil cooler, an Exhaust Gas Recirculation (EGR) cooler failure, as well as performance add-ons… all of which will lead to increased cylinder pressures.  These cause the TTY fasteners to fail prematurely, since the bolts are stretched beyond their yield specs, and the head gasket will soon fail.

 

The installation procedure for replacing the OEM TTY head bolts can be relatively simple, to complex.

The question becomes:  Are you replacing the TTY bolts as a preventative maintenance procedure, or is this a repair caused by one of the three factors mentioned above.  Regardless of the situation, because the early examples of the engine is prone to the failure of the oil cooler and/or EGR cooler, it is advisable to consider these as Achilles heels for the engine.  Even a preventative maintenance head bolt replacement, should probably include replacement of those two components to avoid a failure in the future.

 

And, if you are considering a performance upgrade, replacement of the TTY head bolts becomes a “must do” item.

 

 

Solutions

While the most straightforward approach to the gasket/bolt failure is to get a new OEM gasket and TTY bolts, the solution itself is more complex.

 

If the underlying cause of the failure is one (or both) of the above mentioned coolers, they must be replaced before addressing the head gasket situation.  In the case of adding performance enhancements, they must be replaced with new, better than stock parts and find a stronger, more reliable fastener and gasket solution.  Both components in early engines were particularly vulnerable to design failure, and there are several aftermarket replacements which overcome the problems.

 

Given the track record of head gasket failure on the 6.0L Ford diesel engine, the smart money would be to eliminate all of the weaknesses – head bolts, the gaskets, the oil cooler and EGR cooler.  Servicing both areas requires removal of the valley cover for the oil cooler/filter assembly, and the intake manifold for the ERG cooler.  Many experts suggest removal of the truck cab to make the job easier, but there are head bolt replacement videos which outline how to do the job with the cab in place.

 

If you are going to replace the head bolts or the bolts and gaskets, you will need to pull the heads off the block after draining all of the engine’s coolant and oil.

 

After the head is off, both the head and block surfaces need to be cleaned.  After that is complete, each head bolt hole in the block needs to have the a thread chaser run down into each hole to the bottom to remove any debris, then blown clean with a blast of high pressure compressed air.  Before installing (or reinstalling) the head gasket, the cylinder bores and piston tops should be wiped cleaned using a clean, no-lint cloth and an engine cleaning solvent.  Using a steel straight-edge, check that the matching machined surfaces of the block and the head are perfectly flat.  Any warpage must be re-machined, to true the surfaces, or purchase remanufactured heads from a reputable supplier.

 

Before reassembling the heads to the block, you need to source high-quality head studs and fasteners to assure a trouble-free installation.  One company, Performance Quotient®, a division of PRW Industries®, offers a solution which focuses on the use of exceptional quality head studs, washers and nuts to clamp the head to the cylinder block.

The core of the Performance Quotient solution is the use of heat-treated, high-strength Custom 4135 Grade 12.9 Alloy Steel Cylinder Head Studs.  Each PQx® #101420 Ford 6.0L Diesel Head Stud Kit contains the required 20 – M14-2.0 x 33.85mm (9/16″-18 x 1.33″) studs, having a shank outside diameter of 13.44mm (0.53”) and an overall length  of 8.8125″, 20 – Custom 4135 Grade 12.9 Alloy Steel parallel ground washers and 20 – 12-point 9/16”-18 Custom 4135 Grade 12.9 Alloy nuts.  Additionally, the kit provides the installer with a 2 ml bullet of medium strength (blue) PRW Threadlocker and 0.5 oz. packet of PRW’s CMD Extreme Pressure Assembly Lube.

 

These studs are centerless ground to assure uniform diameters, and feature rolled threads for greater strength and thread conformity to the block holes (as compared to cut threads).  All studs, washers and nuts feature black oxide protective coatings.

 

The studs should be installed using the installer’s preference of threadlocker or engine oil.  The studs should be installed in the block finger tight initially, and if desired, snugged into place using the proper Torx driver, using the holes in the end of the stud.

 

It is advisable to use a new OEM replacement head gasket set (or a performance grade gasket if increasing power, or doing heavy towing).   The intake and valve cover gaskets must be replaced as well, and again, use OEM or better gaskets for best results.  While the factory may not specify that the turbocharger be serviced at this time, it has already removed, and probably should be cleaned, serviced and the seals and gaskets replaced before reinstallation.

 

PRW assembly lube should be used to install the washers and nuts, coating both sides of the washers and the threads.  Following the recommended tightening sequence, PRW recommends a four-step torqueing process – two rounds at 90 ft-lbs, loosening the nuts after each round, then retorque.  Then loosen the nuts and retorque to 130 ft-lbs, and finally loosen all nuts and retorque to 180 ft-lbs. to complete the installation.  This procedure is identical both for a new, replacement gasket, or re-installing the old head gasket.

 

The installation of new head studs on the 2003-07 Ford 6.0 L Diesel V8 diesel engine is indeed a long process when compared to a similar installation on a gasoline engine.  However, the piece of mind and operational longevity makes the investment of time, labor and material well worth it.

DieselArmy.com: PRI 2019 High-Performance Diesel Shaft Rocker Kits from PRW

 

Full Article can be found here: https://www.dieselarmy.com/features/pri-coverage/pri-2019-high-performance-diesel-shaft-rocker-kits-from-prw/

 

By BOBBY KIMBROUGH  |  DECEMBER 18, 2019

PRW Industries teased the industry a few weeks ago with a simple statement on their website: New Diesel Rocker Arms Coming Soon. As we passed their booth at this year’s PRI show, we spotted their new product line of diesel rockers.

Everyone can agree that diesel engines work as hard as any combustion engine, and they do it in the most hostile environments. Diesel means power. Products designed for diesel engines have to be able to withstand the awesome amount of power, and the heavy-duty applications these engines exist within.

Valvetrain has historically been a weak point for many diesel engines. PRW engineers have worked to help stabilize the valvetrain in these workhorse engines. PRW’s Bill McGloghlon showed us the company’s latest products.

First in line is the Dodge Cummins high-performance shaft rocker system (part #3235911). Designed for the 1987-1998 12-valve 4 and 6 B series turbocharged engines. These shaft rockers come complete with silicon-bronze bushings and McGloghlon assures us “they are a perfect upgrade to allow more power and efficiency from the engine.”

They come with everything you need, from ball adjusters and fasteners to the silicon bronze bushings.

The next new product in the PRW line is a similar item, except for the 1998-2018 24-valve 5.9 and 6.7 engines (part #3240811). “Each rocker is made from alloy steel substantially thicker than stock,” said McGloghlon. “Our shaft system is made as a ‘drop-in’ assembly using the stock ratio.”

For more information on these or other products from PRW, visit them online at prw-usa.com.
