Question: do you have a wear ridge at the top of the cylinder wall?
I read how tough our engines are, but at over 300K miles like you and I have, I wonder if there indeed is a wear ridge at the top.
Nope, I didn't have that issue
Great! Good to hear! I hope I'm as lucky when I rebuild mine (if I do).

Is it necessarily a problem if my lifters have no spring action? There was no tapping or anything before I tore everything down, but they are as solid as a rock when I try to push the center.

Also, I have been trying to install the valve stem seals and I cannot get them to seat flush against the valve seats. I am literally pushing down as hard as I can with my thumb and actually had one of the springs around the top of the seal go flying off. I was able to get it back on with a lot of TLC. I just don't think it is supposed to take that much effort to get them on there. Or are there not supposed to be completely flush with the valve seat?

If you look at the pictures you can see the green seal material that i tore away trying to get the old seals out. The seals stick up a little bit above the top of the guide. You should feel a tiny snap or some kind of movement.

When you install a new seal try and pull it off with your finger, it should be hard to remove

I never did feel a snap or anything, but there are definitely snug...I just want to make sure that I have them on there right, it would really suck to have done all of this work to the car just to have the valve seals leaking :banghead

They do not go all the way down. Just push with the thumb and see if they pull off.

Those lifters need disassembled and cleaned. The should have good spring action. Soak them in kerosene for a few days and a couple times a day, try working them. Then take them apart and clean them.

I don't know what the deal is..I have been busy for the past week and finally had some free time today. I made another attempt to get the stem seals on correctly, after pushing down with a lot of pressure (using my thumb), I am still able to wiggle them around with pliers. Either these seals are wrong, or I need to gently tap them down with a socket....I don't like that idea, but these seals are giving me hell and really don't know what else to do.

Am I the only one that has had this problem with the seals?

I couldn't get the valve stem seals to seat well etiher when I used just my thumbs (apparently I've got weak thumbs...) I ended up using the end of the handle on my rubber mallet. The mallet gave me something to get ahold of, the handle was small enough in diameter to get in and do the job and I could "feel" them seat as I pushed down. It was my hope that the wood would have enough give to not deform the seal and it appears to have worked as I am now 10k miles later and no issues so far.

Thanks, I really like that idea, I will give that a shot. I did however go out and buy new valve stem seals, even though I already bought new ones from rockauto...those were the ones that didn't feel right...I even tried tapping them in with the hammer and socket and still wouldn't seat, so I thought it was a possibility that they sent me the wrong ones so I just went and bought new ones instead. Hopefully these will do the job.


Also, did you have to push down with a lot of force (using the rubber mallet) or did they go on with ease?

I had the head on the floor and I just put my weight on the mallet until they seated, didn't have to thump it or anything. Some where between "with ease" and giving it a "calibrated whack".
