Valve Tools

[JDKaiser]

I am trying to remove the valves from a 48' 8n but I havn't been able to remove any of the guides. I got one of the retainer clips out using a pliers and pulling down, but it tore up the clip and the guide still wouldnt come out. Any Ideas on how to get the entire valve guide assembly out?

I was able to borrow a valve spring compresser from my neighbour - looks like a giant G clamp - I am going to give it a go tomorrow - the idea is that it compresses the spring to allow you to remove the keepers which then will disassemble the valve in place - you can then remove the valve....thats what I was told - I will let you know how I get on :shock:

There must be a valve lifter used for L head engines on every work bench in america.Small plier type,I have 4 plus one for small engines.I have the bar type used on flathead Ford V8s.

VALVES REMOVE FROM THE N ENGINE

First remove the manifold and the tappet covers.

Fabricate a tool from a big heavy common screwdriver that can be inserted into the valve ports and used to push the valve guides down enough to remove the horseshoe retainers that hold the valve guides at the bottom of the valve guide just above the spring.

When the retainer is removed then it is possible to drive the whole valve assembly out the top of the engine up through the valve port .

The spring keepers can then be removed and the valve assembly disassembled.

Seals are only used on the intake valve guide and they will be the ones that are the hardest to remove from the block because of the old seal being like hardened glue on the outside of the old intake valve guide. Only use guide seals on the intake when reinstalling the valve assemblies.

Body of Message:
The best way I have found to get the valve assemblies out of the block is to use a big flat/spade screwdriver that has been ground down about 1/8 inch or so just up from the tip end about a 1/4" inch or so and long enough space ground down to let the cut out come out past the side of the block.
Place the screwdriver/prybar into the valve port on top of the valve guide close to the valve stem and pull up on the screwdriver/prybar to push the guide down enough to pull out the horse shoe keeper.
Next take that same screwdriver and place the tip end on the spring close to the end of the valve guide and smack it a few good ones with a hammer to drive the guide/valve assembly out the top.
Once it is out the top you can depress the spring and take the keepers off to dis assemble the units. Don't loose the little cup thingies that are on the bottom of the exhaust valves if it has rotating exhaust valves in it.
Only the intake valve guide should have seals installed on them when you go back up. None on the exhaust valve guides.

I lost my valve tool somhow so today I used a screwdriver, worked just fine, I tried using a small pickle fork to get some slack, it worked ok but not as good as the screwdriver...Jim

Just got done pulling two 2n engines apart,first one took 3 days,tulip valves.Broke 2 guides,had to cut off 1 valve,and make a removal tool out of a small welders j type adjustable clamp.I cut a notch in the flat end to fit the valve stem and used a socket on top for the valve to go up into.Also made an tool with a couple of jogs in it to go under the head of the valve to reach the top of the guide to tap it loose and be able to remove the clip.
If the clips can be moved with a punch,get a large one and grind an 1/8 dia.x1/4long area and just insert in clip and drive it out.These are cheap at YT.
If you have the straight valve stems ,just remove the retainers(keep everything in order),pull the valves,tap the guides down and pull clips,then remove the guides.
Some are easier than others,like I said the 1st engine took 3 days,2nd one,from the time it hit the engine stand till the cam came out was a little over an hour.
good luck,jim
