7 hours is max labor time depending on configuration, so depending on labor rate and parts price its reasonable that its 1000 total.

 

just exactly how does it do that?
the intake hose has engine vacume thru the intake manifold.
the clean air hose gets air from the intake system and feeds it to the crancase. pressure,from where?? if it were there could pop either hose off.
if pressure from blowby,?? its a bad motor at that point. the hoses would go b4 a seal.
pressure ,if there, could escape thru the dirty air intake hose if it didnt pop off. or thru the clean air hose to the filter side

 

Easier to google it then copy and paste.
1. Excessive oil consumption and leak

A bad PCV valve may have a leak, which will cause excessive oil consumption. In addition, you may also notice oil leaking through the seals and dripping on to the floor of your garage. This is because the pressure in the crankcase may increase when the PCV valve fails, so the oil is pushed out through the seals and gaskets as its not allowed to escape any other way. The leak will cause your vehicle to use more oil and leak oil beneath your vehicle.

 

The positive crankcase ventilation (PCV) valve helps to evacuate gas from the crankcase of the engine. The PCV valve directs these gases back into the combustion chambers via the intake manifold. This plays a large role in engine efficiency, improving emissions and the overall operation of your vehicle. A bad PCV valve will affect the performance of your vehicle, so there are a few signs to watch out for before the valve completely fails:

 

If you pull oil fill cap off with engine running do you have pressure or vacuum?

 

there is no pcv valve in the i5 engine

should be vacume

 

No there isn't, your right. But it still has a PCV system. Description below is straight from service manual.
A crankcase ventilation system is used to consume crankcase vapors created during the combustion process instead of venting them to the atmosphere.


Fresh air is supplied through a filter to the crankcase, the crankcase mixes the fresh air with the blow-by gases and then passed through a positive crankcase ventilation (PCV) orificed tube (5) into the intake manifold (3).


The PCV orificed tube (5) restricts the flow rate of the blow-by gases using a 2.5 mm (0.098 in) orifice located in the camshaft cover tube (5). If abnormal operating conditions arise, the system is designed to allow excessive amounts of blow-by gases to back flow through the crankcase ventilation fresh air tube (6) into the air cleaner resonator (1) in order to be consumed by normal combustion.

 

Every internal combustion engine creates crank case pressure, they never have 100 percent seal from combustion chamber to crank case. Its either a vent on valve cover to allow pressure to escape. Pcv valve which moderates as pressure or vacuum changes or a closed orifice type system like in the I5 engine. Pinch off the pcv pipe under the air intake plenum at back of engine if you want to try it.

 

Missed bottom of your post, yes should be vacuum but not much on this engine. Excessive vacuum would indicate too much pcv flow. Pressure would indicate restricted pcv flow or worn piston comp rings.

 

One more right from the service manual.


A plugged crankcase ventilation system may contribute to the following conditions:

• A rough idle
• Stalling or a slow idle speed
• Oil leaks
• Oil accumulation in the air cleaner resonator (1)
• Sludge in the engine

A leaking hose may contribute to the following conditions:

• A rough idle
• Stalling
• Unstable idle speed

The crankcase ventilation system has no serviceable components so no maintenance of the system is required.
