Sticktion????

We had discussed this and came up with nothing official... this is a good explanation though, good find Larry. I recall Googling "stiction" a few times but came up empty. One thing about this page is all of the typos including "HEUI" and the fact that is is promoting a flush...

Is "Sticktion" even a Real Word?

 

 

 

Our friends at Ford Powerstroke / International Truck and Engine Corporation have recently modified the English language by finding a new use for a rather unusual word.

 

The term Sticktion is being used to explain what happens when motor oil used to pressurize electro-hydraulic fuel injectors (such as the (HUEI) breaks down and carbonizes inside the injector. This temporary adhesion can slow or prevent the movement of components within the injector. This delay can have serious negative effects on the operation of the injector and the engine.

 

Both the Ford Powerstroke and International versions of the 6.0 litre or VT 365 can suffer from this problem. This problem can also happen to any Electro-hydraulic type injectors.

 

The primary cause of this problem is thermal breakdown of the engine oil. This problem can be resolved by using an engine flush product designed to break down and remove carbonized oil deposits. It is important to dissolve the deposit as opposed to simply breaking it apart which can cause carbon to lodge in the injector damaging it to the point of requiring replacement.

 

Enertech Labs “E - Flush” will do this quickly, effectively, and safely with or without a flush machine.

 

Some technicians have tried adding diesel fuel or other solvents to the motor oil to attempt to break down these deposits. This is not recommended as it will remove lubrication from various engine components causing increased wear and or damage.

 

To prevent this problem from reoccurring (or occurring in the first place) it is important to maintain suggested oil change intervals using a CI-4 rated engine oil. The addition of a supplemental oil additive such as Enertech Labs EOA will provide an additional level of detergent-dispersants, thermal stabilizers, and other necessary components to prevent oil breakdown.

 

Ford and International hope to resolve this and other problems with introduction of the 2007 Tier III engines. These new engines will be 6.4 litre, twin turbo models using piezoelectric actuated common rail fuel injectors.

I first heard the term in the 70's in reference to motorcycle front forks. Aside from wanting bushings that slid smoothly, air pressure supplimenting the coil springs in the front end was challengine the seals. The nature of the lip seals was that more pressure made them clamp harder on the tube, but a more compliant material had a shorter life.

 

In this case it supports the oil change interval arguement, doesn't it?
