Sinister Diesel 1999.5-2003 7.3L Powerstroke, Pedestal O-Ring Kit – SD-UPPIPE-7.3-ORING
The o-rings for the turbo pedestal on the 1999.5 through 2003 Ford Super Duty 7.3L Powerstroke are prone to leaking, and this Sinister Diesel o-rings kit is all you need to get your truck safely back on the road. An oil leak, of course, could lead to turbocharger failure, damage to your engine and even a serious under hood fire.
Even if these diesel o-rings aren’t currently leaking, it is recommended that you replace them anytime you remove the turbocharger whether it be for upgrades or repairs. Be sure to remove and replace the lower pedestal o-rings whenever you’re servicing the turbocharger to avoid the added time and cost of dealing with a pedestal leak down the road. Trust us, you’ll thank us later.
The Sinister Diesel o-rings are constructed from a durable synthetic polymer called Viton, which meets SAE J200 standards for heat, aging and oil resistance. The o-ring design is precision molded to meet or exceed OEM standards, to keep your Powerstroke running properly.
This kit comes with four diesel o-rings (two for the pedestal to the engine block and two for the turbo to the pedestal). Follow factory torque procedures for proper installation, which is 18 lb-ft to tighten the pedestal to the block and 35-37 lb-ft to tighten the turbo to the pedestal.
