V8: blew cylinder 3, "misfire", now screeching sound and messed up engine!

Well this should actually never happen to a 2UZ-FE V8 engine! Aren't they known for reliability?

Started getting engine fail signal, not steady but blinking yellow sign, reading as "misfire cylinder 3". I was on a 400mile trip in the middle of nowhere and could not stop. 50 miles later there is a screeching sound coming from the engine, obviously something wrong with cylinder 3. I can see without disassembling the engine that on cylinder 3 there are explosions lifting the assembly with the spark plug slightly. Damn! Still got 100 miles to go!

Engine runs rough, clearly there is an issue with power, although the remaining 7 cylinders still produce enough power for the ride. Once I reach home the screeching sound is so loud that I am scared I might have blown the entire engine!

Was searching all over the net to find similar symptoms but could not find anything with these symptoms. Belt was changed, oil also, just two hours before the problem appeared the engine was running smooth and powerful and gave no indication of a mechanical problem.

Shoot, this was for the last 6 years my best ride ever! The T4R was the most reliable and comfortable I ever owned! Don't wanna loose it!

Any ideas? My guess: broken valves? Stuck ventil? Will need a mechanic for that, my skills are not sufficient for these type of problems.

From your description, it sounds like the spark plug has come out of the head. You'll know more after the ignition coil is removed and you can examine the plug and threads.

It would seem unlikely that if it was anything mechanical that was part of the rotating assembly that would make any kind of screeching, banging, clanging, or other metal-on-metal sound that was audible in the cabin while driving, it would have vomited metal components onto the roadway long before making 50 miles.

What's the current state of the oil? Is it full of metallic shavings? Pull up the dipstick... if it glints metallic, it's sheer luck she made another 50 miles.

If it looks normal, it's probably the sparkplug's come apart, as waypoint said.

A blinking SES light is the sign of a serious problem, and should have meant stopping to see what was wrong!

Your problem sounds like it started off with a Spark Plug that backed it's self out, causing a misfire. It probably would have been as simple as tightening the plug and being on your way.

Driving another 150 miles on 7 cylinders with a plug smashing it's self between the threads and the ignition coil under combustion pressure while forcing unburnt fuel and oxygen into the catalyst was a bad idea.

If I had to guess: you've trashed the plug threads requiring a new cylinder head, destroyed the ignition coil, and melted down at least one of your catalytic converters.

Thanks! You are dead right!

It is the spark plug! Got loose and gives me a hell of troubles now! Very annoying that I could have prevented all of this sh--t if I just had tightened it up at the first sound it made. Another lesson learned!

But how come spark plugs that have been tight in place do get loose? At the last service I have handed new IRIDIUM plugs to the dealer. He gave them back to me, saying they do not need to be changed yet. Have they opened it and not tightened it properly afterwards? No way to find out now.

Now I will have to cut a new thread in the head for cylinder 3. And in the worst case do a full overhaul of the head. Grrrr

Seems I am not the only one this happened to: Stripped out spark plug threads in engine - what now? | Toyota Tundra Forums


On a first check it seems that I do not have any metal shrapnel in the engine, oil looks clean. Let's hope its just the thread that has to be cut new.

Did you get this resolved or fixed? I had the same problem towards the end of Oct with a 2006 Tundra with the 4.7 VVTI motor. Driving from California to Northern Virginia. We were traveling at about 70 mph on the freeway when a check engine light came on. We looked for a wide spot to pull over and probably travelled 5 to 10 miles more before pulling over. During this time, the engine got a little louder and was missing. After we pulled over, I found that the #3 cylinder had blew the spark plug and burnt the coil. We had it towed to an oreilly's auto parts store and spent a few hours at night trying to fit it. Fortunately, in the morning the manager was able to locate a spark plug rethreader tool and inserts which I used to fix the cylinder. I also replaced all the other plugs and found they were all loose. I had purchased the truck In April 2019 and had done the timing belt/waterpump and all the ancillary belts, tensioner, fan clutch, fan bracket, radiator and such but did not check the spark plugs because the truck was running great. We had used it to drive to the Arctic Ocean/Alaska and home to Virginia in June/July without any problems.

After my parking lot repair, I was able to drive 1400 miles to home The truck ran great and I thought that I would not have any more issues. After about a week I noticed a metallic noise coming form the driver side of the engine. It sounded like a bad lifter or bearing. Long story short, having the engine replaced with another 2006 engine with 130k to replace my current engine with 275k.

Check your spark plugs and make sure their torqued or snug depending on how you do them. OP hopefully your engine does not have any other issues. Please update us with your fix. Good luck.

Oh, sorry to hear that your engine was toast!
As to my engine the fix seems to work. We put an insert in and checked all 8 spark plugs. 5 were loose, although not much. The engine runs fine, so far no metal in the oil and smooth operation of the engine.

Right now I am replacing the chain inside the transfer case. Second time already. Not exactly constructed by a genius.... I will never understand why TOYOTA went from the indestructible manual HIGH/LOW gear to this crap idea of switching gears with an electric motor. What a stupid idea! Looks like someone intentionally constructed a weak element!

Yep, a silly, silly, stupid thing that potentially messes up the engine! Glad if this forum helps others to prevent this!

Seems I am lucky, my engine runs fine with the new inlet for the spark plug thread in cylinder 3.

I haven't read of this being a common thing, there are many here who replaced their plugs after buying the vehicle with over 100,000 miles on their T4R and find out it had the original factory plugs in the engine, you can easily tell when they are the original plugs because Toyota installed Denso plugs in one side of the engine and NGK plugs in the other side, this is because the left and right heads come from different factory and they use the plugs supplied to them by Toyota in the heads and the factories were supplied with different brands of plugs, this is the same with the V6 and the V8 so there would be many reports of plugs becoming loose if this is a common issue.

There's only two ways this can happen. (1) not properly torquing the plugs during installation and they back out; or (2) overtorquing the plugs during installation and stripping threads. Either way, it's avoidable.
