With just four fasteners employed per cylinder (with sharing), a relatively small bolt diameter and being of a torque-to-yield design, the factory head bolts don’t stand a chance in the 6.0L Power Stroke.
Under the excessive cylinder pressure the 6.0L can create, the TTY bolts stretch, a head gasket blows and you find coolant residue on the degas bottle.
To make the installation of the billet pump gear housing as seamless as possible, Merchant includes a tube of RTV silicone, blue threadlock and the transfer-case-to-transmission adapter gasket you need to perform the job.
The kit shown in the previous image showcases Merchant’s basic pump upgrade kit (less the fluid pictured), which retails for just $75 and is intended for the proactive truck owner looking to address the pump rub issue before it becomes a major (and fairly expensive) problem.
For the truck owner that discovers the pump rub deficiency too late, Merchant also sells a kit that includes a new rear transfer case housing ($499.95).
As 7.3L Power Strokes age, engine oil leaks tend to develop in the pan or at the oil dipstick adapter.While variable geometry turbochargers provide instant response at virtually any engine speed and can double as exhaust brakes, their moving parts are prone to failure.Due to being present in the exhaust side of the turbo, the vanes, unison rings and/or actuators are constantly exposed to soot, carbon and grime buildup, not to mention rust.The billet adapter is secured to the oil pan thanks to a steel brace (which sits inside the oil pan) and two Allen bolts.With the Allen bolts torqued to spec, both O-rings are compressed against the outside wall of the pan for a leak-free seal.All of the above can render the moveable parts required to function inoperable, which leads to poor drivability, excessive smoke and forces the issue of cleaning or replacing the turbocharger.Any VGT-equipped engine is susceptible to this type of failure, but in the diesel pickup realm it’s highly common on ’03-’07 6.0L Power Strokes and ’07.5-newer 6.7L Cummins mills, while still being fairly prevalent on ’04.5-newer Duramax applications.Knowing that the immense labor costs involved in pulling the engine and oil pan just to replace a part are hard to swallow for many 7.3L owners, Strictly Diesel came up with the Dipstick Adapter Repair Kit.It can be installed with the oil pan still on the engine and the engine still in the truck.In the diesel industry this is known as “pump rub” and it’s one of the stealthiest component killers you’ll find.Get this: the hole develops high enough on the transfer case that fluid will only leak when the truck is moving.
