Either way oil is getting into the combustion chamber. If it's valve guides, you need to have the heads looked at, if it is rings, the bottom of the engine needs to come out.
Ballpark estimate is $100 per hour labor plus parts, the new valve guides price.
Yes you can. I'd check the valve guides for wear while you're at it though. If the valve guides are bad a new seal isn't going to be a long term fix.
CAUTION: Some models are equipped with anti-theft-radio make sure you have the activation code before disconnecting battery * Disconnect negative battery cable * Detach the accelerator cable from the cable guides on the valve cover (It's not necessary to remove the cable guides unless you're replacing the valve cover) * Disconnect the PCV and breather hoses from the valve cover * Remove the spark plug wire cover bolts remove the cover and then remove the… Read More

Valve guides and/or valve seals can be worn. Allows oil to get into the combustion chamber.Oil consumption and smoking are signs of either bad piston rings or bad valve guides/valve seals.A compression check on each cylinder can help determine which.
No, the pcv valve is not even close to the transmission.
No, not unless there is a problem with the valve which is rare.
Worn valve guides? New answer : Worn valve guides WILL cause some what of a rough idle and engine would smoke at all times. If engine smokes at start up only and then quites then your problem would be the VALVE SEALS.
It means the piston rings, valve guides and valve seals are in good condition.
to change valve guides, there is no reason to remove engine from vehicle. u do need to remove the heads , as the valve guides are in the heads.so u need to remove,the inlet manifold, exhaust manifolds,probably the distributor,the alternator, and anything else that is bolted to the heads. TAKE THEM TO A MACHINE SHOP!!! trust me, you dont want to try to do this yourself!!
It doesn't have a modulator valve. It doesn't have a modulator valve.
valve guides are present in the engine cylinder head.these valve guide operates the working of valves in the cylinder.that is the inlet ant the outlet valves.
sounds like bad valve guides, and/or rings If engine runs smooth when hot? I don't think it's the guides I would check the valve seals. also need to pull valve covers to make sure oil return holes are open in the heads.
yes heads need to be removed

The pcv valve is located on the top of the valve cover. It is a plug in type and just pulls out.
This could be caused by a clogged PCV valve, worn internal seals, or worn valve guides. A clogged PCV valve will pressurize the engine internally, which force oil past important seals into the exhaust stream. Likewise with worn seals, oil simply leaks out. Worn valve guides makes it possible for oil to seep down the exhaust valve into the exhaust stream.
valve guides or valve guide seals or piston rings. in colder weather?
My guess would be bad valve seals and/or worn valve guides.
Never heard of that happening, but if it did it would indicate very badly worn valve-guides.
Your car smokes from the exhaust manifold area and tailpipe when the car is cold or been sitting up for a hour?
The cause could be worn valve guides. As the engine cools oil can seep down through the valve guides around the valve stems and collect in the head and top of the cylinders to be burned off when the engine is started.
the valve guides could be worn out The carburetor is running fuel rich and needs adjustment. If it were valve guides or rings the smoke would be blue

This is a machine shop procedure which the head has to come off to accomplish.
The typical causes are worn piston rings or valve guides.
It can be a number of things, but the most common problem is worn valve guides.
Worn rings or valve guides (more likely) Check compression.
The engine valve stem seals are worn. Usually valve stem seal replacement is all that is needed, occasionally there is wear in the valve stems and/or valve guides which requires further repair.
Excessive blow-by from worn rings and valve guides. A faulty or disconnected pcv system.
You'll have to pull the heads and have the guides and seals replaced. Bad seals are usually an indication that the guides have worn as well.
