NOTE: If a new engine emits a small puff of smoke immediately
upon engine start-up, there may have been a small amount of
preservation oil remaining in the cylinders, induction system,
and/or fuel nozzles/lines. The smoke should quickly dissipate; if
smoke persists, shut down the engine (“Engine Shutdown” in
Chapter 7 of the TCM Installation and Operation Manual (OI-22))
and investigate the cause.

relief valve; oil pressure is not adjustable. If oil pressure drops
below the specified operating pressure at idle (10psig) or normal
operation (30 to 60 psig), remove the oil pressure relief cap and
inspect the plunger, seat and spring according to instructions in the
TCM Overhaul Manual (OH-22). Reface the pressure relief valve
seat or replace the plunger and seat, as required.
