A thought crossed my mind whilst reading RAVE manual the other day regarding TD5 injector seal replacement.
The setting of the injector rockers/pushrods states to bottom out the injector plunger with the rocker with the cam lobe at full lift, then wind the plunger out 1 turn.
I have done two engines now and have always wound back 1.5 turns. Would this result in a reduced injection pressure = reduction in power?
It all stems from the statement in RAVE:
"This adjustment procedure should be carried out whenever the rocker shaft has been removed. When adjusted correctly, the injector plunger travels the correct distance. If not adjusted correctly the plunger could either travel too far and make contact with the base of the chamber or may not travel far enough. In both cases, damage and a reduction in engine performance could result."
I understand how the damage can occur if the plunger bottoms out in the injector chamber but not sure about the other extreme.
Cheers
