Valve guide seals; Special tool

Hey folks. I don't know how helpful this is going to be, but I figured I'd pass it along. I have been messing around with this junkyard motor I got recently, and I've been reading on here. Well anyway, I read how much trouble valve guide seals can be to remove. So I started looking around my shop for a 'special tool'. I came up with this little guy

It's just a generic Home depot paint can opener, but it's perfect for getting under those seals. The lip of this thing is the perfect size.

I halfway stuffed a towel in the lifter bore so this metal tool wouldn't booger up the sides if I slipped. All I did was get under the seal on either side 2-3 times and pulled really hard, and "pop", the seal came right off. I'll bet if I got really creative with some threaded rod and 3 of these paint can openers I could build a screw type puller tool, kinda like a gear puller, only smaller. Maybe that can be tomorrow night's project...

Like I said, I don't know how helpful this is, but it seemed like a pretty neat trick at the time, so I figured I'd pass it along. I can see how you might wrestle these seals for a while with a smaller pick or something.

Get two and make them kind of like a pair of scissors. Put a spring on the end attaching the two together, so its pushing them away from each other. Pull the handles apart to close the end. Push in, release handles, and you have a nice tight grip on both sides. Its an idea.

Could y'all add your 2cents worth in-

Read lots about how to remove them, but-

What is the correct way to install new valve seals back into the head? Best I can do at this point is lube them up with some oil and push them on as hard as I can with my fingertip. How do I know if they are seated all the way down- or is there a remedy?

little by little....

Hammer and chisle. Beat the piss out of them until they cry uncle. The bigger the hammer the better. If you don't have a chisle, then a piece of rusted re-bat will work fine. As far as getting them all the way down, don't worry about that, just know after ten minutes of beating the first one down, it should be set.

Or was that how to get information out of an Al-queda member? Sometimes things just rattle around in my brain and just confuse me.

I think to seat them, get a wooden dowel just a bit larger in diameter than the valve seats, and gently push them down until they won't go any further.

Use either method, one should work. Best of luck.

I push them on with my thumb. Don't take much to seat these.

I found an appropriate socket- just big enough for the rubber and spring yet small enough to fit around the metal housing. The first was pushed on with my thumb. Then the socket for the remainder. There is a noticebale change in the sound when hammering once it bottoms out.

Make sure the spring collar is already in there. Learned the hard way on the last one. Had to gently remove the seal, add the collar, then replace the seal.

The keepers are a bear if anyone is doing this Macgyver style. I fought, cussed, took breaks, complained, meditated, etc.- but ultimately all 6 are done and my hand is bruised from trying to hold the needle-nose pliers just so. Probably will go down as the most difficult part of the re(build.) THe spring compressor at AutoZone was to big and in no way usable for the Metro. The best inexpensive solution would be a helper for this part.

Not the correct post, but for those who read & know, do them keepers need to be exactly offset or mirrored from each other around the stem when installed? seems like mine touch on one side (3o'clock) and have a gap on the other (9o'clock.)

Don't hammer on them. They only need pressure with your fingers to seat.
