people have said it can be done, and some say it can't..i'm gonna be swaping out my valve train and don't want to remove my head.is there a special springs compressor needed? please let me know!!

 

Are you planning on removing the valves, or just the springs and retainers, etc.?

 

most people buy the snap on valve spring compressor, a bit pricy (~$110), i belive lisle also makes a comparable one for a bit cheaper. keep the valves up with compresed air.

 

swapping springs,retainers --not the valves, i know the head has to come off for the valves

 

this one is a little cheaper than snap on i believe

i used the snap on and just put my pistons at tdc and worked on them that way. 1-4,2-3 and it took only about an hour and a half. no rope or compressed air needed.

 

Are you rotating the engine without the cams? I'm looking at these tools and i'm not sure how to use them.

Would this be something similar to the tool posted above?

 

rope thats funny. I knew this ol' timer that did it that way.

I have been thinking about making my own tool.

I like to pull the head so if you drop a retainer you can get it back

 

Buy the snap on tool, worth every penny, I've used it many times, payed for itself already. Very very very simple to swap springs/ret w/out taking off the head.

 

hehe .. technicly, you could probably take out the valves w/o pulling the head ... think about it!

 

I have seen that and also the valve adjustment tool on that site, they're only maybe 10% cheaper than Snap-On, so I would probably just get the Snap-On stuff. It's pretty easy to used, I watched a friend remove a valvetrain with that tool. He would compress the valve spring while I stuck my telescopic magnet in there to grab the keepers, then he would let it go slowly and remove the retainers and springs and set them aside in order.

 

Are you talking about the old "pull out the oil pan, the crank and pistons so I can remove the valves" trick . Must be a biatch the reinstall the valves afterwards though.

 

no you couldn't. look at a block you'll see why

 

Unless the bore interferes with the valves dropping down after you remove the pan, griddle, splash plate, crank, rods and pistons, ... you might be able to drop the valves out the bottom of the block w/o removing the head.

Definately not the smartest way to do it, but it just might work!

 

cant remove the pistons from underneath. 100% not possible. The snap on link didnt work for me, but that other link isnt the tool i would recommend. The one we use is much simpler. Just use a hammer and the tool, and the tool catches all the keepers because its magnetic.

 

You can't pull the pistons from the bottom. Look at a block

 

My bad, that's why I don't build motors!
