Is the Mitsubishi 3.0 liter a interference motor?

Mitsubishi 3.0 is a interference motorYes, 3.0 Mitsubishi is an interference motor The Mitsubishi 3.0 engine is not an interference engine , if you tear the timing belt it will not hit the valves. you can confirm this with alldataIf your motor is the 12 valve motor you are safe, but the 24 valve version of the 3.0 is most definitely an interferance engine & if the water pump, timing belt, tensioner or any idlers fail your valves will be kissing the top of the pistons.....

Is normally open valve and fail open valve the same?

"Normally Open" or "Normally Closed" are classifications that refer to actuated (not manually operated) valves. For an actuated valve, the "normal" state refers to its position when the actuator is not energized.Therefore a normally open valve is one that is open until the actuator is energized to close it; if power to the actuator fails, the valve opens or "fails open".Likewise with a normally closed valve if power to the actuator fails, the valve closes or "fails closed".The "normal" state of an actuated valve must not be confused with the "usual" position of the valve during routine operation of the system. A normally closed valve may be open continuously over a long period of time while a process is running, but it is still a normally closed valve. It just happens that this normally closed valve is usually open.For an actuated valve to return to its "normal" position, there must be some force, often a spring, that moves the valve from its actuated state back to its normal state. If a valve is actuated to open and then actuated to close, it will "fail" in whichever position it is in when the activator is de-energized. This type of a valve is not considered "fail safe".A normally closed valve might be used in an application such as the loading of gasoline transport trucks where in the event of a power or automation system failure, you would want to stop flow.A normally open valve might be used in a situation where you want flow to continue in the event of a power or automation system failure. This might be the case for the cooling water system for a nuclear reactor or for an actuated valve on the water piping to the fire protection system.


What weight oil does 2007 Chevy silverado use?

5W30 OIL I have read that in The hot months it is safe to run 10W30 weight. The reason you can't use heavy weight oil is because of the roller valve train. it will be to thick to lube the valve train and cause it to fail/burn up.

Gunk high mileage motor flush safe?

Well in theory all it should be is concentrated detergents. That being said, you shouldn't keep it in the motor for any extended length of time, also, don't use it as an additive to motor oil. Throw it in, take it out! If anything does fail, its not going to be because Gunk is so powerful it ate your gaskets. Your gaskets were old and bound to fail. If your that concerned, you should be looking to the junkyards for a newish-er block and save your money.


What is meant by air to open valve?

An air to open valve is a type of control valve that requires air pressure to be applied in order to open the valve. When the air pressure is removed, the valve will close automatically. This design is commonly used for safety-critical applications where a fail-safe operation is needed.
