There is a way. It takes a bit of ingenuity tho.
Remove the plugs, feed a small rope into the cylinder,turn over the engine by hand to push the rope against the valves and hold it there.This holds the valves closed so you can remove the springs.
At that point you need to compress the spring to remove the retainer to remove the springs and the seal.after reassembly,back the crank off and remove the rope. Repeat on all 4 cylinders.
This actually works, but it takes you to make something to compress the springs.
Just remember, all movement is done by hand only.

i understand all that. infact i can do the air pressure to. would a chevy door spring compressor work to compress the valve spring. can you slide the rockerarm over & tie it there with a wire tie to hold it out of ur way? i don't have the valve cover off yet so i don't know if there is a bolt hole there to use for a piviot point of a tool that i might be able to make.

Probably easier to remove the rocker.That will provide the holding spot for your compression tool

Not a thing.it's gonna move, unless you can strap it in place on the back end.
Perhaps a 3" piece of metal with a plastic bushing to allow the cam to turn.
Or you could just put on new belts.
Sometimes,trying to do it easier ends up taking longer.just not having to remove the heads is enough.
By the way,why replace the seals?

I have some steel,grinder,welder,etc.I made the tool I needed.There wasn't anything on the shelf that was available.Valve spring compression tools are designed to clamp all the way around the head.
I've used a bar with holes in it attached to the head and a hand made "fork" to push the retainer down.
Getting the keepers out without loosing them was the hard part.Use a magnet to capture them.

well it won't be the first time for me to make a tool either. will tackle this soon, thanks for the advise. i have a tip doing timing belts. the right cam will turn when u take the belt off, then u have to realign it. line up timing marks, put wrench on the cam bolt on the right head. then slip a new belt onto the wrench. then wire tie wrench to the frame snugly. this will hold cam from turning. take belt off. remove & replace left belt then slide the right side new belt past the old one, install it & adj the tentioner. no need to have to realign cause it didn't move for me. later

I wish the local sales guy knew about that when I needed one.I did a Dodge 383 with a hand made one.
That was before the internet tho.
And yes we had electric lights back then :D
I think they were called..the electron consuming,photon generating,filament device :roll:
