Easily Un-Sticking Piston Rings | Low Compression In One Cylinder

Disclaimer: This procedure is not endorsed by anyone.
I was recently working on a Dodge Ram with a 4.7L V8, with a cylinder 5 misfire and low compression in that cylinder. I figured out that the cause was stuck/sticking piston rings. This video is simply to document how I freed them up.

This can and does work and actually GM in the '80s recommended that in order to free sticking rings in the 6.2 Diesel to fill each Cylinder with half a can of Cylinder Cleaner, leave overnight, crank engine with glow plugs out then run at highway speeds.

I’m in the middle of trying this myself and found this video. Great reassurance. I’m day 2 of soaking with seafoam. Really hoping this works for me!

You got me to watch a 7 minute clip of a single valve cover and occasionally a finger. It took me 7:04 seconds to realize that lol Considering my atrocious ADHD, I'd say you did a good job of being literate and explaining everything just right

Great video! Thanks. What do you think caused the rings to seize up?

@TheAntarcticEmperor Жыл бұрын

Thanks. I'm still not sure of the original cause. My best guess is just a 1-in-a-million unlucky carbon deposit on the side of the piston.

I watched an old man fix an engine that rings didn't seat in one cylinder. He took a spoonful of comet and put it down the sparkplug hole. Ran it a bit changed the oil and no smoke.

Comet, the gritty cleaner? Straight powder in the plug hole? Sounds like a bad idea but hey if it works

The best thing to do is to spray the cylinder generously with PB Blaster, let it soak overnight. Crank it in the morning and boom.

Wet/ Dry compression tests all cylinders..Lots of "Blaster spray lubricant"...Write down all psi numbers for reference..Double duty for high mileage motors....

Use Berryman's B-12. Works better

I got one for you. I have #1 cylinder at just 60psi compression. Holding. The other 3 in the bank hold steady at 150 130 130. I"m at a loss, If it were rings or head gasket, or valves wouldn't it bleed off?

@TheAntarcticEmperor Жыл бұрын

Are you using a regular compression gauge? All compression gauges I'm aware of are gonna hold their reading unless the Schrader valve at the end of the hose has been removed. If you're using a regular, unmodified compression gauge, then your results so far are normal for a single-cylinder low compression scenario. Let me know what kind of setup you have going on and we'll go from there.

@@andybilakshow260 More than likely the air will leak out of the cylinder giving you 60 PSI before you'll have any idea where it's coming from. If it were me I'd go ahead and put a teaspoon of engine oil in that cylinder, turn the engine over a few times without the compression gauge, then attach the gauge and repeat the compression test. If compression improves significantly, the problem lies in the piston rings (or, rarely, the actual cylinder walls). If compression does not improve more than a few pounds, it's more likely valves, head gasket, or worse.

@@TheAntarcticEmperor I believe a head gasket. It's a good thing sort of because I have 2 stripped valve cover bolts in the back that need to be drilled & tapped. Piece of cake since I have to have the head off anyway.. Thanks.
