as long as the engine is running you have constant pressure and airflow. This is where these gasses come from, the blow by from the rings which all engines have. nipper

I missed the trike part. I dont understand CA emissions so I dont know how they handle things like that. Ive seen stuck or clogged pcv system blow seals, and pop out dip sticks. nipper

hehehe backfires made life exciting Another thing that people forget. All these little systems have helped add longetivity to engines. In the 1950's 60,000 miles was considered high, now 150,000 is high, and higher for our subarus. It doesnt take much to contaminate oil. Some moisture may sound insignificant, but get a little water in the wrong place and damage can happen. Superior fuel control, better oils, a tighter oiling system all help in this process. PCV valve has been around since 1955. http://people.ucsc.edu/~kbrandt/mustang/smog.shtml nipper

Emissions will matter if he fails the visual test. Also if he drives short drives where the engine never warms up, condenstaion will matter. Weather the car is garaged or not, moisture is moisture and its in the air if the system is wide open. nipper

re re re re read what ive been saying. Or i dont know what your saying. the pcv valve is closed when the engine is off. the valve is open when the engine is running. This draws out unburnt gasses and keeps the pressure from building up and causing leaks. Breather tubes, pcv valves, breathers all come from the valve covers . They come from the highest point to remove the gasses. As an engine runs, the crankcase (containing the crankshaft and other parts) begins to collect combustion chamber gases which leak past the rings surrounding pistons and sealing them the to the cylinder walls. These combustion gases are sometimes referred to as "blow by" because the combustion pressure "blows" them "by" the pistons. These gases contain compounds harmful to an engine, particularly hydrocarbons, which are just unburned fuel, as well as carbon dioxide. It also contains a significant amount of water vapor. If allowed to remain in the crankcase, or become too concentrated, the harmful compounds begin to condense out of the air within the crankcase and form corrosive acids and sludge on the engine's interior surfaces. This can harm the engine as it tends to clog small inner passages, causing overheating, poor lubrication, and high emissions levels. To keep the crankcase air as clean as possible, some sort of ventilation system must be present.

Yes you are missing something. The part about the engine being off. The pcv valve is weighted so it closes when there is no pressure to open the valve. Didnt wikipedia make any sense? nipper

PCV is the vent to the atmosphere, but only when the engine is running. And since the engine is a huge air pump the cankase gasses get drawn into the engine and burned. nipper

PCV = Postive Crankase Ventilation Valve. It is a one way valve. When there is positive pressure in the crankase, the blowby flows out into the the manifold or air cleaner. When the engine is off, the valve seals so no outside air can get in the crankase. What is the point of plugging it anyway? it does no harm and robs you of no power. If anything it helps add time to the life of an engine. nipper

Bcause as the car cools down, it wil draw fresh air into the cankase. There is humidity in the air, and water and oil dont mix well, especially if you drive lots of short trips. Also you will fail inspection if you have emissions. nipper

http://en.wikipedia.org/wiki/PCV_valve NEVER plug a pcv valve. Engines were never totally sealed, they used to be vented to the atmosphere. Now they are vented to the manifold. nipper

Blu threw a rod at about 4700 RPM climbing a pass in california. There was a huge hole in the block. I paid a lot of money for a new engine, but i also told them i didnt want to open the hood except for fluid changes till the next timing belt. So alot of hoses were replaced and other things. nipper

now now sometimes they are our freinds, they keep us from falling to our deaths depending where you are nipper

They are non asbestos so you can just toss them in the trash. nipper

i didnt even know there were two generations.... *takes notes* nipper

Mine is born again with a new engine aand 201,000 miles. nipper

SOunds fine to me as long as you head our advice. nipper

How does the car run? is it running a lttle rough? The HVAC controller is a bunch of vacume operated switches, which is fed from a resivoir. If nothing at all is working either the HVAC control went bad, or there is no vac to control. nipper

This is the thermostat housing. When was the last time this car got a timing belt/water pump change? Also get yourself a haynes manual, its full of all sorts of good info. nipper

Listen to the engine carefully for rod knock. At 200,000 if the HG goes its just age not design fault. Make sure the tires match, inspect the fluids, drive the car in figure 8's to check for torque bind. How much they asking nipper

What is this "snow" thing i keep hearing about. It's dec 26th, and my strawberries are in bloom. It's 62 degrees outside. It should be in the low 30's. At this rate i may have to trade in the Outback for a convertable.... nipper

er um, yes. There may be different cam profiles, lifts etc. This is just asking for trouble. Heads should match. It may be that there is no effect, and you would be the first to try this, but unless you like pulling your engine apart, heads should match. You may never have a smooth idling car. Also there will be an odd amount of stress on the timing belt. nipper

I spent more then that, but i am very very very happy with my rebuild. i also had some extra things done. I am getting a bad feeling about your rebuild. Things like why was the engine sent out to a machine shop..... nipper

You need to do a wet dry compression test. Even though the oil rings are not compression rings, if the ring broke there can be more wear on that cylinder and lower compression. Another way to tell is to pull the plug and inspect it to see what it looks like. Even something as simple as a broken oil ring can cause a connecting rod issue. It can put the piston at a slight angle and put side forces on the connecting rod bearing. You may also have a stuck piston ring. Did you check the end gap of the piston rings and make sure that the gaps were offset from each other ? nipper
