Valve guides - Jeep I-6

In theory, yes. In practice? That's another matter.

You have to remove the cam shaft, then you can pressurize the cylinders one at a time, and remove the valve springs, then take the guides out and put new ones in.

And yes, they can. But, you need something to keep the valves from falling in. Either compressed air into the cylinder (leakdown kit if you have one, or a long bit of cord you can pack in.

You can also rotate the engine so the pistons are up for the cylinders your working on. Then use a bit of vac hose to hold onto the valves. (don't use vicegrips it farks up the surface) ... I know someone who did this then wondered why his new seals wore so fast. :/ amazing.

While your in there you might want to go ahead and replace the valve springs. It's fairly cheap and the springs do weaken over time. Also check the push rods/rockers for proper wear pattern.

Do you mean valve seals? As another replied, guides are part of rebuilding the head. Off the jeep and with valves removed.

Ack!.. but there are dumb answers to questions.

Seals, yes, guides, no, that's a head-off and take it to the shop operation.

No, but the seals can be.
