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

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. - Auta a dopravní prostředky
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!
Did it work for you???
Update?
Berymans b12 works better than seafoam
Loved the story thank you! 😂
Use Berryman's B-12. Works better
Great video! Thanks. What do you think caused the rings to seize up?
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.
Thank you...
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
Ima check mine this weekend😁
Going through the same think on cylinder 5 on a 4.3 Chevy Silverado I have 35 psi. Going to try it
Did it work?
Did it bring compression back ??
How much sea foam do u ad?
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
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.
I hope you’re right. Going to give this a try
@@JoeyBeavshey did it work?? Im thinking about trying it today
B12 berrymans works better for a piston soak. @@ace_man100
Wet/ Dry compression tests all cylinders..Lots of "Blaster spray lubricant"...Write down all psi numbers for reference..Double duty for high mileage motors....
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?
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.
@@TheAntarcticEmperor Good point! I didn't even realize the valve on the gauge. I"ll check with it in the morning. THANKS!
@@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 you didn't have to throw in the
'or worse' in there did you?🤣
@@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.
Does anyone know what compression A Toolbag had before treatment?
100 lbs
00:35 You had 65-180 on compression test ?
165-180, I misspoke.
I watched again !00 psi lol
Have you had any misfire error code on cyl5 before the fix?
Yes, misfire on cylinder 5 before the fix. So far no complaints from the owner about the misfire returning since I did this.
