Cylinder Head Oil Rail End Plug

Part Number:



High Pressure Oil Rail End Plug & Gasket - Ford 7.3L (94-03)

Oil rail plugs located on either end of the cylinder head require a specialty o-ring if they begin to leak. This is the large round 1 3/4" plug with the 1/2" drive socket hole. During engine rebuild it is good practice to replace these plugs and gaskets since they are almost impossible to reach once the engine is installed in the bay.

Order of 1 is 1 plug, gasket o-ring and instruction sheet.

Ford and Navistar's instructions recommend the use of LocTite 277 threadlocker on the Oil Rail End plugs

    Cylinder head oil rail end plug 7.3L

    Posted by Unknown on Sep 24th 2018

    Part arrived as scheduled. Nice price. It was hard to change it out on my 97 F350 7.3L but it is do able without moving the engine. My friend and I unbolted the down pipe from the turbo and lifted it up and over just enough with a crowbar and a prybar together. Recommend a very thin 1/2 drive ratchet to ratchet out the plug.

    Pulled my injectors for o-rings, figured I should do these while the oil rail was drained. Fronts were a snap, rears were a bit of a nuisance but I also had my old uppipes out so the process was not too bad!

    Was looking for this end plug and found it here at Riffraff. It is the new up graded plug that is longer than the original one and comes with one single gasket. Insulation was easy just don't forget to buy the locktite for the proper installment of the plug.

    Thanks Riffraff for the great product at a great price.
