CHANGING VALVE GUIDE SEALS WITHOUT REMOVING THE HEADS

In this video I demonstrate a way to remove valve springs without removing the heads from the block.

You video was very straightforward with no distractions. I'm getting ready to do my small block Chevy and can use your instructions. Thank You!

Thanks, brilliant though .I am a tad dissappointed that you have not made more vids... EXCELLENT post dude, better thn most of the fancy shops .. clear, concise, and CLOSE UP .. we can see it.. Now I have to a=djust the valves...

Cool idea bud. Some helpful tips... maybe, valve spring compressor tool 2.0 don't cut the end off the wrench just bend it.
Tip 2 use a length of old spark plug wire in the spark plug hole push it in till it stops coiling oh make sure the piston is at TDC compression. Way faster and safer and no need for an air compressor 😊 but I like what you did here great video

If you don't have a compressor or access to electrical power, you can pack the top of the cylinder with cotton or a hemp twine as well. That's a pretty slick valve compresson tool through for sure.

You're a crafty fella. Thanks for the ideas on this! My 89 Vettes got some seals that are going. ARG.

It's strange how hard the person has to look for information like this.
What I see done differently everywhere, and what I've been told everywhere, makes this job confusing.
I've been told if it's leaking it needs new valve guides.
I've been told to only use the O-rings.
I've been told to use the O-rings and an umbrella seal but only on the intake side because the exhaust heat will destroy the umbrella seal.
I've been told that if you use both seals, it won't get enough oil to lubricate the valve stem.
I've also been told to just using the umbrella.
I've been told to get Viton seals, did I heard pros and cons for different reasons.
crap, ill just buy a new engine and be done with it. 😁
Thanks for the video 👍

Excellent tool mode on the wrench!! Great job over all. Appreciate/subscribed!!

[brianb]

I might be underthinking it.... but why did you fight with the o-ring AFTER putting the spring back in place? I don't see anything that would prevent you from putting that o-ring where it needs to be in the first place and then setting the spring on top of it and compressing/installing keepers. Something i'm missing ?

[BrianYoder-tkkj]

Great question.. how many psi are you runni g? I need to do this on my roadrunner..

[jasonbaill]

hey thanks, got to do this, mine ( 305, 5.0 sbc ) smoking a lot, try this first don" want to pull or replace the engine retired got to save $$$. many thanks. J.

[jasonbaill]

hey, thanks looks like someting I can accomplish, many thanks J. 😃

Usually the umbrella seals are for the exhaust- the rubber with the clamp ring are for intakes- hope you didn’t just get them swapped.

Put a crescent wrench on the end of your valve spring compressor tool and pull upwards

[WoodgemanX]

Where did you find your welder? The sparkplug to air adapters are $10 for a set of three sizes. How much was the wrench, how many drill bits did you dull before you drilled through the wrench?

[philliphall]

Done a lot this way on 283, 327&350 engines back in the day
I used a oil burner adapter and braze fitting in it and air hose

[MariamMelodies]

quarter inch or three eights nylon cord works also. just pack it into your cylinder head and leave some sticking out to pull when finished

[dynabodyfitnessneverold]

I have used 3/8" rope in the spark plug, turning the crank by hand until piston stops (with all the spark plugs out). Then with a spring compressor, released the keeper and took the spring off to replace the valve guides.

[gregorydavid]

May be a dumb question to some but why dont u put the O Ring on before u drop the Spring back on ?

[winoseti]

i use a party balloon down the plug hole. err make that 2 party balloons one inside the other. flat c spanner ex lawnmower tool for the press. camshaft still in place. which you can gently lever off. you can get the spring off by pushing the valve down on the balloon.

[chasedavis]

Can you put each cylinder to tdc and use the piston to hold the valves up?
