Hi all, I am interested to understand the purpose of the check Valves (1 per feed line from the engine driven main oil pump).
A Check Valve can have one out of three different ways of "operating"
1. The normal way, allows oil to flow in one direction (towards the valve body and in to the crank case) but not in the other direction (when crank case pressure is higher than oil pump deliver pressure and would therfore effect the pressure in other three oil supply lines via the main oil pump outlet manifold)
2. Failure Mode Nr 1; Stuck Closed
3. Failure Mode Nr 2; Stuck Open
The Normal Way and Failure Mode Nr 1 are both quite obvious, but what if it is Stuck Open (as in "3. Failure Mode Nr 2")?
What would be the effect of a "3. Failure Mode Nr 2" situation?
My thinking;
1. Only environmental effect (higher oil consumption) i.e. will smoke more
2. It will brake down with catastrophic effect
This is an almost philosophic question, Please keep your answer to the topic, I am not interested of tip like "mix the oil in the fuel tank insted" or "that is a crappy engine"![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
