I'm showing you how to replace valve seals without removing the cylinder head. I'll show you how to do it with compressed air & with rope. Also, I'll show you how to use two different valve spring compressor tools. The engine we are working on is a Chevy 250 straight 6 out of a 1967 Chevy C10 pickup truck, but the basic idea is similar for many different engines.
You can watch this video for another example of replacing valve seals:

Man, thanks for the video, enjoyed the commentary, can we be neighbors? same garage style, same stuff falling off the bench, very normal things...lolol
That's funny. It's just life I guess. You're welcome for the video. Thanks for watching it.
What a brilliant idea. Thank you!
Glad it was helpful!
Cool. Thanks for your effort.
You're welcome.
awesome!
Very informative 😜
That's good because that's why I made the video.
My case is low compression? So . looks like this can be what I'm going look into?
That's usually gonna be bottom end. Usually pistons,rings, cam or crankshaft is leaking
No. Most likely not. Valve seals don't have anything to do with sealing the cylinders. If you got low compression in a cylinder or cylinders, those cylinders are not sealing. Something that seals the cylinder is worn. A couple things it could be would be worn out piston rings or valves that are not closing they should.
Funny good job

Can someone explain why you need the air compressor or the rope if the piston is already in the top possition of the compression stroke that would prevent the valve from falling in.
Because there's still a gap between the valve & the piston. The valve will fall down just enough to where you can't get the new seal on. You need the valve to be all the way up. In this example anyways. I can't speak for all engines & all scenarios.
@@freemansgarageextra thanks for responding, makes sense.
doing that does it change the timing
No. It does not change the timing. Your timing can only change if you loosen & turn the distributor.
If you're there why not replace the valve stem seals too .....
I don't understand. I did replace the seals.
@@freemansgarageextra no you only replaced the o rings
@@jagalasso You'll have to explain to me what you're thinking because to me the o rings are the seals.
@@freemansgarageextra ok. So the valve stem seals are down further and right above the head. Are you an actual mechanic because this is like pretty early in stuff they teach. Just watch a video on CZcams on valve stem seals.
I can't tell if you're messing with me or not, but I have completely disassembled & reassembled this engine more than once. There is only one location on the valve stem for an o-ring/seal & it is what you watched me do in the video. This is a 1967 Chevy 250 cubic inch.
DO NOT EVER PUT ANYTHING IN THE CYLINDER.
Do not ever put anything in the cylinder of your engine #fgextra
WOW....The rope trick has never bent a valve if done to TDC on compression stroke.
@misters2837 this is so stupid.. 20 other ways to check TDC. but If you wanna play games...
