How to Replace Valve Seals Without Removing the Head

If your car is leaking oil and you think it may be due to bad valve seals, you can replace them without removing the head. This is a fairly easy job that can be done in a few hours, and it will save you the cost of having a mechanic do it.

Step Two:

Before you can remove the old valve seals, you need to remove the valves themselves. This can be done by removing the valve cover and unscrewing the valves from their seats. Once the valves are removed, you can then remove the old valve seals.

Step Four:

Once you have the new valve seal, apply a small amount of lubricant to it. This will help it to slide into place more easily. Next, take the valve seal and carefully place it into the groove on the valve. Make sure that it is positioned correctly and then lightly tap it into place with a hammer. Repeat this process for the remaining valve seals.

Step Five:

If you are comfortable with removing the head, it is the best way to replace the valve seals. If you cannot remove the head, you can still replace the valve seals by following these steps:

1. Remove the rocker arms.

2. Remove the pushrods.

3. Remove the valves.

4. Clean the valve seats with a valve seat cutter.

5. Install the new valve seals.

6. Install the valves.

7. Adjust the valves.

8. Install the pushrods.

9. Install the rocker arms.

Step Six:

Assuming you have the head off the engine, remove the old valve seals. You’ll need a few tools to do this, including a pick, a small screwdriver, and a pair of needle-nose pliers. Start by prying the old seal out of the groove with the pick. Once it’s loose, use the screwdriver to pry it the rest of the way out. Be careful not to damage the groove.

Next, use the needle-nose pliers to remove the valve spring. Once the spring is out, the valve seal will come right out. Repeat this process for all the valves.

Now, it’s time to install the new valve seals. Start by lightly lubricating the groove with oil. This will help the new seal seat properly. Then, using your fingers, press the new seal into the groove. Make sure it’s seated evenly all the way around.

Finally, reinstall the valve spring and use the needle-nose pliers to compress it. Once it’s compressed, use the screwdriver to lock it into place. Repeat this process for all the valves.

Step Seven:

Once you have the new valve seal in place, you need to reinstall the valve spring. Make sure that the spring is seated correctly in the spring retainer, then install the spring cap. Torque the spring cap to specifications.
