Anything we can do to patch this up for way less to make it another year or two, or is it time to throw in the towel and buy a new vehicle?
Patch it up, reset code, trade in car

How did the mechanic come to the conclusion of a bad piston ring gap?!
Here is the report:
Recommended service
Cylinder Block Assembly - Engine - Piston Ring: DTC P0303:
No. 3 Cylinder Misfire Detected,
FOULED SPARK PLUGS CAUSE BY EXCESSIVE BLOWBY DUE TO THE PISTON RING GAPS HAVE LINED UP.
RECOMMEND BANK 1 (CYLINDERS 1-3) PISTON RINGS TO BE REPLACED.
PRICE:
PISTON RINGS KIT CYLIDERS #1 TO #3,
6 SPARK PLUGS
TIMING BELT PACKAGE
The piston ring is a vital component of the piston. It provides a tight seal between the piston and the cylinder wall creating compression that is vital to the combustion process.
$4,980.00

Wow, this exact same thing happened to my wife’s van 2015 Honda started running rough, took it to my mechanic said same thing, temporarily fixed it, told us to trade it in so we did.

Some good recommendations in here. Especially get a 2nd opinion from another shop that ain't a dealer. Find that shop through word of mouth referral if possible. Or these days good ratings I guess will help.
As for passing inspection, you may be able to get it passed by unplugging the battery for a bit before bringing it to the inspection shop. That should reset codes for a while... Could be 30 minutes, could be a few hours.
Btw, we have a 2019 Odyssey. Not our first Honda, but it'll be out last. My car in college was an old 79 Accord. Loved that thing. But, Honda's quality and engineering have tanked, imo.

Ok. After doing some research and reading all the good advice here. Here is what I’m thinking.
1. Replace the spark plugs.
2. Install an active VCM shut off device like ( S-VCM )
3. add some Chevron Techron or equivalent to the gas tank, Warm the engine up, then and drive the car aggressively for a bit. Got that advice from here Odyssey Club
Thought ?

Plenty of places. Usually going into an Oriellys or similar, and asking managers there for recommendations, works pretty well.
I wouldn't spend 4000+ on anything 8 yrs old.
But repair shop should be half

Just curious.
So when the engine is assembled at the plant, the rings are staggered. So, over the years, the rings have kind of spontaneously migrated into alignment causing this problem. Shouldn't they eventually migrate back out of alignment?
Seems like you should be able to keep changing the spark plug and wait for it to clear itself.

Don't see how they could possibly know that the piston ring gaps were lining up without a full teardown of the engine. The flashing check engine light does indicate a misfire, but can be caused by different issues. Time to get another opinion from someone besides the dealership.
Exactly! No way they could know this by connecting to a computer.

Results and quote came back: Cylinder mis-fire due to piston ring gap lining up. $4,980 to fix. That sound right? The van is 8 years old. About 120,000 miles. Anything we can do to patch this up for way less to make it another year or two, or is it time to throw in the towel and buy a new vehicle?
Is it using any oil? Smoke out the pipe?
Do any of the plugs show signs of fouling?
It could be something so minor as needing new spark plugs. The ford ecoboost engines are notorious for that. The plugs wear… gap widens.. boost blows out the plugs on acceleration… engine misses… cel flashes. The fix? Simple tune up. It really can be that simple.
Could be a bad coil pack. Anything like that. It all depends on what the plug looks like.
And the rings on a healthy engine constantly spin in the piston grooves while running. Now if you haven’t performed good maintenance.. the gunk will clog up the ring lands and muck things up… but even if they “align”… it shouldn’t be for long. On a healthy engine that is.

In the old days we put sawdust in the oil and roll the coal!!

Yep. Talked to some other folks who confirmed that. No way Honda admits their “EPA BS” VCM put oil into the cylinder

It's a fuel injector cleaner mainly for direct injection engines. Won't solve a piston ring issue. Search for Marvel Mystery Oil or similar results, YMMV.
Scotty Kilmer or Project Farm on YouTube might be useful.
Don't overdue the Techron, it will blow the O2 sensors near your cat convertor.
Good luck, I'm sure it's frustrating, that's a big $$$ # for new piston rings and timing belt.

The cost is so high because its not an easy thing to reach, pretty sure the entire engine needs to come out. If that is the case, Id replace all those coils while they have it out since those parts are probably relatively cheap. You can probably find someone to do it for cheaper though.

If you’re in Houston and your insurance is up to date, just leave the keys in it and park it in Sunnyside.
Edit to add: keys may be optional

If it's past the warranty extension, put a new spark plug in that cylinder at every oil change.
It's fouling out from oil contamination.
Assuming the oil blowby is the issue this is a good solution including maybe going one heat range higher on the plug.
I however, don't think it is a viable solution. The Odyssey has a transverse mounted engine. The odd numbered cylinder back is against the firewall. While I have never been under the hood of an Odyssey I have never changed spark plugs on a transverse mounted engine that the rear cylinder back didn't require quit a bit of effort to get to. You generally have to take off a lot of stuff off like the intake plenum, a dozen vacuum hoses, fuel rail, air cleaner, MAF sensor etc. If you are handy and have the tools you could probably do it in an hour to 2 hours depending on the vehicle but especially if you are paying a tech it is likely not an option you would want to pursue. Had it been a cylinder on the 4/5/6 bank it might take ten minutes beginning to end to switch out one plug.

Well blowby is certainly from bad rings, bizarre to see on a Honda with that little mileage.
You can see bad blowby by unscrewing your oil fill cap while the engine is running, pressure will blow out. I'd get a second opinion on this from a different shop first. Bad diagnosis happens all the time. If it is blowby, run an anti fouler and keep spare spark plugs to change as needed, only takes 5 min to change.

My daughter has a honda accord. She has the same problem engine light on car misfiring. I changed spark plug and ignition coil problem solved.
