How do you replace valve stems and guides on a 1989 Jeep 4 Cylinder engine?
NO... You MUST remove the heads and take them to a machine shop and have the valve guides replaced. No other way.
yes heads need to be removed
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.
Yes.Yes.
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.
check the idle control valve not that hard to replace and inexpensive
Three possibilities. Overfilled with oil. Worn cylinder or rings. Worn valve guides. On most smaller engines, it's cheaper to replace the engine or the short block. If the engine has overhead valves and the valve guides are worn, a short block won't fix the problem.
possible bad valve guides or blown head gasket possible bad valve guides or blown headgasket
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.
