Planning some much needed R&R
 

Been putting off some needed maintenance on the old girl. Plans are to do the following:

Lower pipe gasket
Lower radiator hose

Glow Plugs (motorcraft)
UVCH if needed
Turbo pedestal o-rings
Riffraff plenum inserts
Riffraff HPX
EBPS Cleaning

Anything else you guys would suggest (or discourage) while I have things apart?
Oil Cooler?
Torque injectors?
Injector o-rings?
Regulated return?

Truck has ~153,000 on it

The Riffraff FRX is a good $ alternative to a full regulated return. You might get Clays Front ABS Grease-able Block Off Fitting.
