Diagnosing a Misfire with a Visual Inspection? (Teslong NTS 500)

How to use a visual inspection to diagnose the cause of a misfire?
This 2011 Ford Escape has a P0301 Cylinder #1 misfire.
Parts cannon already fired spark plugs and ignition coils at it, and the next round is a PCM!
Once we narrow down the offending cylinder, the TESLONG NTS 500 dual camera endoscope lets us see what is wrong with this engine. Pretty cool stuff!

[@maryannmoran-smyth3453]

Never do a one Valve Valve job you’re just asking for trouble down the road. When you get the head of the vehicle do a complete head overhaul and even shave the head.A rounded valve margin or valve touliping is a sign of trouble which could also be caused by a Loose valve guide. Tearing down motors for 20 years I have learned that the first thing to go on most engines the top ring on the piston, exhaust valve guide and/or exhaust valve.Back in the 80s, LOL I saw my first endoscope in a Mercedes-Benz dealership and it blew my mind. Great review. Keep on rockin

Easy and cheap repair , if the valve are not bend then, adjust the valve and add 0.5 mm extra valve clearance drive the care the valve will most likely reseal , check valve clearance after a month leave it lose for another month , your car should be back to full compression

[@Cheepchipsable]

He loves it. Has had it for a while. Check his videos, he does a comparison with a couple of other scan tools.

[@throttlebottle5906]

i wonder if the guide backed out/moved or ran low/out of oil and the timing set is shot, it's possible to bend a single valve out of a pair, tolerances are never perfect. only other thing, is the seat moved from being overheated, which would mean warped head, gasket, block sealer in it. best bet, just slam in used engine

[@kevinbarry71]

I love those used car guys, I change the spark plugs, that didn't work; I guess I'll change the computer next

[@honcho714]

What scan tool is that ?

[@jdtractorman7445]

I just have to laugh when the auction guy says it must be the computer. When in fact with most any electrical issue, that's what I look at as last on the list of possibilities. I like that scope, affordable too. Just curious if you do an injector leakdown test when you have a valve problem like that, or do you check that when the valve has a chunk of metal out of it?

[@PineHollowAutoDiagnostics]

Good question. Apparently just a defective valve on this one, surprised how good the other exhaust valve looked!

[@JuanOrtiz-mo8be]

So how does this get fix , new valves or new engine?

[@shaunadams3170]

I'd say head ,gaskets and timing set. Because new complete head is around the same price as sending it to the machine shop. Used head from the salvage yard would be even cheaper but then you take the chance of being in the same spot. And I say the timing set because odds are it hasn't been done but that's where you talk to the customer oh wait auction car so he doesn't know.

[@JuanOrtiz-mo8be]

Here in Russia, head repair will cost 1/4 the cost of a contract engine. They always repair their own head.

[@kittty2005]

I swear I saw dents in the piston and corresponding dents in the exhaust valves, in piston heads could be fly cuts or casting impressions to give clearance for valves but never in valves because they are usually set up to rotate to reduce wear and localized heating, odd.

[@bryanlatimer-davies1222]

I guess a look down another cylinder would tell all

[@kittty2005]

@@bryanlatimer-davies1222 A look at the bottom side of the head would be more practical, if the engine has high miles and the oil pump is at rear of engine, it's not uncommon for the valves in No. 1 cylinder to get sluggish from oil starvation and over heating, the oil is also a coolant. I've seen computer simulations of worn guides with insufficient lube, worn valve stems in said guides, high rpm, high heat and a peculiar thing occurs a harmonic vibration is set up and causes the valve stem to rock in the guide and for a micro-second the valve locks and is struck by the piston, also because of uneven oil distribution the front valve springs usually relax, old age helps.

[@dealerauctionnightmare4689]

Does that relative compression test mean it's down 17% or it's only contributing at 17% of factory-recommended compression?

[@PineHollowAutoDiagnostics]

I think it's an arbitrary number...

[@gorak9000]

One other cylinder showed 1% and it says "OK", so it must mean 17% reduction, not 17% left (if the number has real meaning as Ivan says in his comment)

That's cheating, but I cheat as well, just hook the air into the cylinder and listen for escaping air. I don't do traditional leak down testing, don't even own a tester. As a retired heavy line tech from Ford dealers it was never a necessity. Management wanted me to have one, but what the hell do they know. I always had some idiot manager second guessing my work, but every time they challenged me, I proved they were full of shit. I took to working under the maple trees at home rather than constantly battling idiot managers. That same dealer in Santa Barbara was closed by Ford for fraud perpetrated by these same managers. The Ford rep said "Congratulations, you guys are number one in the nation, on warranty claims, I am here to audit you" That is when I decided to move out of State and do my own thing. I didn't mind service writers, but, managers are totally useless.
