Replace Valve Seals on 350 Chevrolet Video 9

This is how I do valve seals on a Chevrolet head.

[@MichaelWilliams-ki9kg]

This is the type of old school/old timers knowledge thats priceless

[@alexbennett658]

Hell yeah. Didn't have to watch a 45 minute video. 6 minutes of old school experience 💪

[@dl7180]

That short video taught me more than these 30 minute videos. Thank you

[@Big_kid]

6 minutes WELL spent. Thank you for helping take the mystery out of valve stem seals, umbrellas, O rings, etc.

[@josaljo1]

Glad it helped.

[@Big_kid]

I had questions before i jumped in, you and Summit tech help took care of them. The Summit spring kit doesn't have the O rings, only the blue umbrellas. They also don't say to reuse the covers on the top of the springs. Google image search shows stock- yes, aftermarket- no. Thanks again!

[@racemastergamer]

Thank you sir. I've been watching alot of these different videos and none show where the oring goes. Hell wasted a ton of time and this saved me a bunch of time.

[@josaljo1]

Thank you, have a good one.

[@masonreeves3426]

Thanks for the vid, really clear and concise. Didn't know there was a difference between the intake and exhaust seals. I'm getting oil into one of my cylinders on my 98 pickup, so going to just pull off both heads while i have the motor apart and do some preventative maintenance. Thanks again.

[@tracyjarvis7323]

Great video thank you. I'm teaching my son about old school engines and your vids help so much

[@josaljo1]

Thanks for the comment. Glad he wants to learn.

Awesome video...just what i needed to see!!!

[@josaljo1]

Good, thank you for watching

[@johnmilner7603]

I use 2 wooden coffee stir sticks to push the O ring oil seal into the 2nd groove of the valve stem.

Whatever works.

[@JH-tk6ge]

When researching valve stem seals on amazon/ ebay, many listings don't differentiate intake and exhaust. They all look the same and are in a set of 16. Viton blue, like yours.

[@JH-tk6ge]

Nevermind, found this on a jalopy journal forum: "Later GM factory seals are positive viton type seal on the intake and hard plastic on the exhaust. The plastic handles heat better. 11/32" stem uses white umbrella. 3/8" stem uses black . No O-rings since early nineties. Vortec heads use a steel jacket positive seals. Intake and exhaust. Color coded because of different materials."

[@whiteboyfromernul]

@@JH-tk6ge my exhaust has the white plastic caps and my intakes have the blue with springs around them but they are 1970 chevelle heads ''441''s that have been reworked for 2.02 and 1.6 so im not sure what to order because they have bronze guides and looks like the valve towers were cut for those specific blue seals?

[@dukeman7595]

Great instructional how to video.

[@josaljo1]

Thank You

[@charlesmartin3265]

Josaljo Won You are the only one that completely show exactly what to do step by step because I didn't even know that I had different seals and not to mention that rubber seal at the top of the valve. I appreciate your help and advice. Thank you Happy New year

[@thedobermangang3503]

i have a k5 blazer 5.7 stock engine in it with about 145,000 im just starting to smoke burning some oil when i accelerate it comes and go when it frist started it only did it when you start it up ..so i guess it have gotten worser..i might try to do the valve stem i would like to do the whole engine but my money is real tight righ now i would have to them with the heads on...

[@josaljo1]

I personally dont like to do them with the heads on, but it is definately cheaper.

[@rustbeltgypsy3713]

Can you put o ring seal on first? Or in compression if spring, will it or possibly damage I ring? And thats why you came from top in-between spring washer.? Thks

[@MuhammadHussain-gz1vm]

thanks you I got the tool

[@josecavada3830]

👍

[@seatonfield416]

Thank you!!!

[@jaime13huerta]

Never done valve seals before on sbc so I need intake and exhaust then

[@josaljo1]

Jaime Huerta yes, it would be a mistake to not do all of them.

[@jaime13huerta]

Josaljo Won can you give me the part number for the other ones also thsnks

[@josaljo1]

Jaime Huerta That number is for complete set.

[@jaime13huerta]

Josaljo Won gotcha thanks again

[@jessesyfie7244]

You are using positive seals on the intakes and an umbrella seals on the exhausts? There's no need to use the o ring seals with them or the shields with them other style of seals.

[@josaljo1]

The old head had the same seals on them and I just replace everything and they work good.

[@TerrybleGamer]

I have a 1978 350 but when disassembling the head, there was only the o-ring. Should I get the umbrella seals too? I've read that some older small blocks didn't come with umbrella seals...

[@josaljo1]

Order whatever the head is suppose to have. Verify the age of the head as well.

[@danielgarcia9095]

OMG I'm going through the same thing mine doesn't have them either...

[@dickeymoore4264]

I have NEW sbc heads that has run about 3 minutes can I reuse the valve seals that are on the heads now?Thanks

[@shathan007able]

Great video bro! Do you know whether those seals will fit on my 1971 Camaro 307 5.0L?

[@josaljo1]

I believe they will, but check with auto parts store.

[@gregcollins737]

Great video! I have never done this type of head and came here to figure out where the o ring went. I am going to do this job with the heads still on the vehicle by pressurizing each cylinder one at a time. my quotation is why couldn't you install the oring on the valve before you add the spring and retainer? this way it would be much easier to see the oring especially with the head still on the engine. Is there some clearance issue that won't allow that? thanks. And again great video!

[@josaljo1]

The retainer on the top of the valve springs is where the oil is sealed. If you put the o ring on first you might push it out of position when the retainer is put on.

[@alisonkunishige3612]

I heard there's a special tool that removes the seals without pulling out the heads?

[@josaljo1]

You can put air pressure into the spark plug hole and do it that way as well without removing the heads.

[@super38javier]

I have a 1990 Cadillac brougham with the 5.7 engine and It smokes on cold startups, could replacing the seals fix this issue ?

[@josaljo1]

If the seals are bad it will.

[@super38javier]

Josaljo Won thank you

[@marcomarquez3156]

Is the smoke blue or white? Blue is oil and white is water.

[@tsutton4673]

I have a 92 Buick Roadmaster smoking like a train is it the same process??

[@josaljo1]

Basically but smoking might come from bad piston rings.

[@tsutton4673]

Josaljo Won Thanks for the reply I’m going to look into that. I do all my own maintenance and repairs but never got into the motor internals but I’m sure if I can find a video or write I can do it.

[@josaljo1]

@@tsutton4673 Hope you find an easy problem to fix.

[@williamb454]

Do you need to put lube on the valve stem when you put it back in?

[@josaljo1]

You can it wont hurt, a lighter oil would be better.

[@williamb454]

Would this fix my issue of smoke at cold start startups? The smoke is white and has kind of a gas smell? Thanks in advanced!

It sounds like it would fix it. Especially if the white shows up in the morning.

[@aceiterosdelvalle2323]

@@josaljo1 I’ll try it out thank you for the fast reply!

[@randy1ization]

does the exhaust valve plastic seal ride up and down with the valve because it doesnt seem to seat like the intake valve seal does.

[@josaljo1]

I like to put oil on everything as I put it back together but the plastic seal may need the guide dry when you first put it on but they should not ride up and down. Heat from the engine after they run a bit should stop that.

[@randy1ization]

@@josaljo1 does the small inner spring hold the exhaust seal down, I am perplexed as to why the seals are different. is the thought is the intake seal is working great oil should not get into the cylinder from the head valley so no need for a just as good exhaust valve, seal ? I know on some 4 cycle motor bike engines they dont even use exhaust valve seals, just intake. I saw on the LS engines the seals look identical except for color, so I imagine the exhaust seal is more heat tolerant.

[@arthirperezjr9866]

Where do i find a valve spring clamp like that and how much do they cost

[@josaljo1]

Napa, under $50

[@limabravo6065]

What size wrench did you use for whacking?

[@josaljo1]

7/16"

[@rayosmith1714]

Does this stop the blue smoke ?

[@josaljo1]

It stops the smoke from oil leaking past the valve stem. But if the piston rings are bad no.

[@michaelharrington8231]

Why is the first cap different?

[@josaljo1]

Exhaust and intake are different.

[@MuhammadHussain-gz1vm]

where to get the tool from?

[@lucydisguise6419]

What tool do you use for on the car applications no removing the head

[@josaljo1]

lucy disguise ii use an air pressure fitting in the spark plug hole, and a lever to push the spring down. Napa has both.

[@oldsilkhat7893]

You can also use rope. Take out the plug make sure the piston is about 1/2 way up on the compression stroke. Put about a foot length of rope down the plug hole and turn the engine by hand just until you get a little resistance. Keep in mind you need a different style compressor tool. They make one that screws down to compress and also one that has a leverage bar. I prefer the rope method over air because if you have poor sealing valves (realistically you should be doing more than seals) but it's possible to drop a valve, which if you have the piston at top dead center isn't bad but it can be a little bit of a pain getting it back up enough to get the keepers back in.

[@jjmccloud]

Do I have to replace those oil caps or shields whatever there called that sit on the top of the spring and retainer

[@josaljo1]

Yes

[@jjmccloud]

Oh, so I can't just not use them lol? I have to buy new ones then, do u know the proper name or pn to look for

[@josaljo1]

@@jjmccloud R u talking about the plastic oil seals or the valve caps? To do seals only you dont have to replace anything made out of metal.

[@jjmccloud]

The metal caps that sit on top of springs. Not the retainers the round deep metal caps. Idk why I said oil caps or whatever I said sry, more like spring and retainer caps

[@josaljo1]

@@jjmccloud Unless you have a problem or severe scoring or damage, I use everything that is metal after putting the new seals on. Hope that helps,.

How to open the valve seal without spesial tool...can u te each me

[@whiteboyfromernul]

i made my own from a large ''c'' clamp,harbor freight has them for @ $8 and a 3/4'' deep well socket,i cut a notch out of the socket through both sides about 1/2 ''wide x 1'' deep so i could get the keepers out with a small magnet,you could stick the socket to the c clamp with double sided tape so it doesnt move around but i tack welded the socket to the c clamp and cost hardly nothing
