Some heads have replaceable guides and you just drive them out with the head off. Others need to be machined to have inserts installed.

By using an air compressor to hold the valves shut, while you work on them. Each spark plug is removed and an adapter is used to screw into the plug location. This adapter is then connected to compressed air. Talk to may reputable mechanic and he can help you.The above answer is right WHEN replacing the VALVE SEALS. But the question was about replacing the valve guides. YOU MUST remove the heads and take them to a machine shop to have the valve guides replaced. NO OTHER WAY.

It is possible that oil is seeping past the valve guides and into the combustion chamber. If your are burning oil, this is more likely the cause. Replacing the worn our valve will fix the problem.?æ

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.

If it blows blue smoke when starting up, that is usually the valve guides need replacing. If it constantly blows blue smoke, you are looking at piston rings. 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.

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.

The pcv valve is located on the top of the valve cover. It is a plug in type and just pulls out.

Overhauling a control valve means replacing all of the worn parts to bring the valve to a condition where it will be able to perform as well as it did when the valve was new.

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 spark plug wires * Remove the bolts that attach the upper timing belt cover to the valve cover * Remove the valve cover bolts and then remove the valve cover

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.
