Run a smoke test on that engine. I had a similar problem with an N54 engine. Misfire on cylinder 6. Customer had done plugs and coils. Came to me to do the injectors. Would delete codes and the car ran fine for 3 days before misfire cylinder 6 set again. I was so stumped at this point. Thinking maybe it was a corrupted ECM. I dont know why, but I decided to run a smoke test and found an air leak on one of the intercooler couplers. They have an oring on them. Swapped it out, cleared the codes, and voila. No more misfire. I was stumped after though as to why it hadn't set a code for the air loss but thats BMW for you 😅
I say its a valve issue - I had the same issue on an EJ2.5 changed all the outside parts to find out the valve was not seating properly and issue solved (thats my bet anyway). Also and intermittent issue.
Every time I watch these vids, it's sooooo great to see how far Quinn has come. I still watch his original videos weekly as I work on my e36, but great to see him doing even bigger builds.
Let's agree that we all need a Quinn in our car lives... I'm glad to see the M3 is healthy again and congrats to Jagger for winning this beauty! Very excited to see what you'll do with the old engine though, I'd like to see a really unexpected swap. Like build it into some Kia or Hyunday or something, make sort of a sleeper with it.
Smashed it Quinn, Love how dedicated you blokes are. You could have totally said nothing and passed the defect on like the dealer did. But, no. You guys fixed it with full transparency
Coming from a real technician, being ASE certified and all that doesn’t mean jack all. I’ve seen guys with zero ASE’s out wrench out diag guys with all the certs in the world. This is lazy unprofessional parts swapping or in this case just swapping out the whole engine..
@@roberthatley7415 Seriously. Jumping from a misfire under load to "lets replace the whole $10,000 engine because throwing thousands of dollars of unnecessary parts at it didn't work". Absolutely unbelievable. This channel is a clown show.
@@roberthatley7415that’s exactly what I said as soon as I heard “we’re swapping the engine” holy hell. This was the most extreme level of parts throwing
"Single cylinder misfire is usually caused by 1 of 3 things: bad spark plug, bad ignition coil, or bad fuel injector." They didn't bother to: * Verify the injector was getting a correct voltage or pulse width. * Pull the valve cover and inspect the valvetrain. * Do a leak down test. * Made a bunch of terrible assumptions, and started throwing parts at it. * And then decided to swap the engine. Cause they couldn't figure it out (and claim they ran out of time). * Check for intake tract air leaks. I'm not even BMW certified and I know that this particular BMW engine can throw a random cylinder 6 misfire if there is a leak in the intake tract. Yeah Certs mean absolutely nothing here, and critical thinking failed. Seeing all the nut huggers in the comments, explains why the auto world is going to utter shit if "techs" like this are being praised, let alone being acceptable in the field.
I really appreciate the mentality and attitude that you guys have towards the situation that you guys remaining positive and continue to put out quality content as well as quality work. As always. Keep up the good work you guys. Much love and hopefully we see a sub on the channel sometime soon😂😂😂
Had the same issue, but on an N54 - same exact symptoms. After a LOT of parts and lost sleep - it turned out being a botched (previus owner) injector seal that cost $4.
Didn't expect to see this on the channel again. Really sucks that happened, good on y'all for taking care of it before the winner picked it up! W garage and team
If you get Engine Malfunction Light or Limp Mode on BMW’s with Push-to-Start (at any speed) you can put the car in neutral & slightly apply the brake, you can push the Start/Stop button 3x in a row, the engine will turn off while driving, it will be in accessory mode. If you then depress the brake pedal & push the Start button the engine restarts as usual & you can engage gear again. It will clear your limp mode & faults on the fly. No need to pull over to a stop every time. Works for A/T & M/T
All I gotta say is, I hope they take care of Quinn. That man is absolutely a fucking goat. That man is carrying the team on his back for sure! Mad love to everyone in throtl tho 😂 Yall stay killing it.
I’d like to see that motor rebuilt and dropped into a 2002, with a modern take on the Batmobile style kit, it would make an amazing build and I’m sure that Quinn would be stoked to partake. Thanks throtl for everything you do. Respect from England 🏴👍🏼
If I was a betting man I bet the spring for the main oil valley thing is either broken or stretched and therefore it’s taking the oil pressure longer to catch up to itself and it’s probably losing that compression speed needed at that particular RPM. I’d take it apart and start checking all the oil valleys within the heads. Maybe pull the covers and watch for those valleys to fill up but that prolly won’t show much if you don’t see something right away. Hope this helps.
I've watched 3 minutes and then paused it. be sure to check the relays for crank and cam sensors. Crank usually throws it into limp mode. Clear the ECU and the ECM and change the relays and also wires tracing back. Good luck lads.
I had a similar issue with my Supra. it was ALL in the tune. Zero actual engine problems. The bad tune would also fix itself when I'd reflash the tune. After a few days of hard driving the issue would come back until I re-flashed the tune.
As a former M4 owner its not the engine :) Replace the Valvetronic shaft and it will fix your issue. its a wear and tear item. Mine did not need it but I know a few CS guys who had to replace it.
The owners and everyone at Throtl are just good guys. You could have passed this on and no one would have known anything. It's just a weird issue that he might have never noticed but you fixed it anyway.
that sucks!!!..what a beautiful car though...and all the work quinn did..what a champ...winner could have shown some emotion...i would have been freakin
Been driving BMW cars since 1971. Currently I have a Crimson Red 2012 135i MSport with six-speed manual. Also own a '72 2002tii and a '91 318is. Great for the roads in Northern California! Love all three of these cars for different reasons, but straight-line speed isn't on the list. ;)
Run a smoke test , vacuum leaks also cause misfires. I would have said check for carbon buildup on the valves but I know Quinn would have checked for that. Direct injection engines are plagued with carbon buildup on the valves since fuel isn't splashed on the valves like in older engines, which cleans them up.
if the compression of that cylinder is same as the rest that might be 1- a valve seal 2- a beginning of a head gasket leak a very small one or 3- a piston oil ring issue not the compression ring
It’s not really getting scammed though, getting scammed is buying an Evo FQ400 and have it blow up 80 miles down the road and the seller block your number and it not even be his house you bought it from, the house was owned by an old couple who were on holiday at the time you bought it and them not even know the guy in the first place 😬🤣🤣🤣
pain. I never knew about fq400 until i read this comment, as its a UK thing. But holy shit i would be pissed if i gotta 400hp evo and it died 80 miles later.
check whether the cables have impedance consistent with the specifications. If not, it is possible that they produce a signal reflection that causes this problem
I suggest you pressurize the cooling system let it sit overnight pressurized and but a borecope inside the cylinder that is misfiring and check if head gasket is leaking. Or maybe is just a recall or service bulletin to update the ecm/pcm
I have the same story about buying my 335is used from a dealer. Misfired day after it had such a mess of non kosher coils and plugs. Eventually it locked up because it was just a spun bearing got a replacement engine with new bearings I had the professionals do at my house! And new oem turbos. Cars running great! I drove it 40miles in the Texas 108 temp and it’s clean no codes rn
You should not be replacing the engine. Your problem is likely related to a boost leak or pre turbo exhaust leak. I would try to do a boost leak test first. 2nd I would inspect the turbo’s wastegate flaps / arms for wear.
It’s a bent valve. Hub was probably spin before and they threw a new hub in and realized the engines was toast and got it to sell. Just had a customer deal with the same issue from a car at BMW dealership. 4 months waiting car ended up getting a new head.
Check if it gets enough fuel. If the fuel rail is connected only on the front, it maybe has not enough pressure or fuel in general for cylinder 6. if that’s the case, check the fuel pump and or the plumbing.
100% a leak on cylinder 6 spark plug and then a misfire on the same cylinder. Really common on most bmw models. You have to do like an walnut media blast or some other media blast on the engine to clean it up to fix the cylinder. That is at least what multiple mechanics have told me and I seem to have the same issue as you. :)
U guys are awesome hope I one day get to work at a similar job. Throtl just looks like what I’ve been working towards. A fun place where cars are modded. No warranty times and crappy customers complaining about an oil leak after getting their radio updated
What is Blud yapping about. They make UA-cam videos and sell merch, not work on customer cars. Could not be more different. The mechanic business is unpleasant and difficult, not glamorous or fun. That is the reality of it.
It’s crazy how these mechanics will have so much pride in fixing a car from ground up and it would run perfectly. Buy when you go to them to fix your car it’s never complete, mechanic insurance! But great job
Sadly, dealerships are not reliable. I worked at the dealership as a maintenance and saw 1srlt hand on how customers' cars were mistreated. Not all of them but some did, and sadly, the customer was the one who had to pay the price. I myself had an unfortunate incident with another dealer, who replaced all the cooling parts in my car, but for some dumb reason, they didn't flash old coolent fully and mixed it with the new coolent. Thus causing reaction and clugging the cooling ports. That day, my wife drove the car and didn't realize that enjine was overheating and ending up blowing the motor. Dealer absolutely refused any responsibility and said that they would have no part of it and that it's our fault that enjine is blown. I never take any of my cars to a dealer ever again.
I will say that being an audi tech i’ve seen this exact problem on audis newish 3.0T found in the b9 s4’s and such, and it has been a broken valve spring every single time, and it’s only when slowly rolling into boost at around 2200rpm.
The one thing I would suggest is to check over boost condition. I would also flow test that injector and if that one injector either is clogged or had a seal issue then under heavy load like your doing would case a lean cylinder and a misfire especially if it’s a very small leak and only arises when under heavy load.
I agree it's a seal issue. I would also check if the problem happened once the cars gas reached a certain amount. I have an X5 where once it's one a 1/4 tank, it causes a drivetrain malfunction and leaks a little in Cylinder 6.
I know there's a lot the cameras don't show but I'm incredibly impressed with Quinns attitude dealing with this. I know there are plenty of mechanics out there that would bitch and moan through this entire engine swap.
Might be a long shot but I have a Volvo S60R that was acting similar and it ended up being the pedal sensor. Every time I would punch it going 50-60mph it would bog and act really laggy, while also going into limp mode..Anyways, hope this helps, love the vids as always🤙🏻
I had this same issue in 2016 Ghibli, whole car would shake if I accelerated at 130km/h if I was cruising at that point for a long time. Sparkplugs and coil packs fixed the issue oddly enough.
I'd like to imagine that since I have been driving BMW's for years now and I have a 2006 E46 M3 and a 2008 335XI N54 Modded to the gills (Around 730HP) that if I won I'd immediately turn off the traction control and burn a few donies right then and there in the lot! LOL. But I probably wouldn't because the character my father, my family and MY GOD has instilled in me would prevail and I'd just have to be respectful and not a total self indulgent tool! LOL! AWESOME CAR! AWESOME VIDEO! Thank you!
Same Stuttering thing happened on my VW, after a while my Turbo blew and it somehow affected the valves, i was told to either get a new engine or complete rebuild. Safe to say i am broke my car is now standing can’t afford to fix it and now without transport😅
Dude this is amazing!! I’d love to see you tackle BMW’s infamous early 2000s 6 series. I’ve got a 650i convertible with the first gen 4.8, would love to see what you’d do to it!
O2 sensors! Have the same problem on my n54 as we speak tip in was shuddering from 1800 to 2500 rpm, snipped the o2 sensor in an effort to change it and it’s even worse now till I pull it out
First and foremost, I must say you yous are the goats. I'm Bobby. I'm jamaica. I've been watching your videos for a long time now, and it's my first time making a comment. I dream of owning a car builbuy you guys, it seems impossible, but I still dream i respect everything you guys are doing. I'll keep watching for as long as you guys are making videos, and im able to watch Stay Safe. your's truly one of your greatest fans
i had a similar issue on my 2010 535i E60, found it was a bad ignition coil. so i bought a whole brand new set of coils, issue fixed... now oil leak again, probably tried fixing leak probably 3times...

Same thing happened with my Pontiac sunfire
Hope the boys see this😊
Great solution, Too bad they already bought a new engine.
We did a smoke test. We also replaced all of the Intake manifold gaskets too. We replaced the MAF & both O2 sensors also :(
I say its a valve issue - I had the same issue on an EJ2.5 changed all the outside parts to find out the valve was not seating properly and issue solved (thats my bet anyway). Also and intermittent issue.

Dude good job guys!! Congrats to the new owner!! I was honestly wondering what happened with the f80 good catch!
Daang, replacing the engine instead of diagnosing the issue that is a ton of work. Kudosss!
Man, you scared the s**t out of me but a possible bad engine sucks. Luckily Quinn is a very good mechanic. Hope all went well. Great episode.

Hesitation problem went away on my n55 when I corrected the oem spark plug gaps to a tuned spark plug gap ratio. Makes a huge difference
I had a similar issue with my Supra. it was ALL in the tune. Zero actual engine problems.
The bad tune would also fix itself when I'd reflash the tune. After a few days of hard driving the issue would come back until I re-flashed the tune.
Totally digging the new music montage. Great choice!!
I had the same car with the exact same issue. Get the Vanos Solenoids replaced and you’re good to go.
Agreed. Being the furthest cylinder, I feel like it has something to do with oil pressure to the lifters
Menace it's so good to see you. I learned so much from your UA-cam videos for my 96 e36 5sp sedan. Are you still creating content?
As a former M4 owner its not the engine :) Replace the Valvetronic shaft and it will fix your issue. its a wear and tear item. Mine did not need it but I know a few CS guys who had to replace it.
Beat me to the comment lol I thought the same thing 👍🏽
You guys are awesome for swapping that out so quickly. Glad everything worked out!

check whether the cables have impedance consistent with the specifications. If not, it is possible that they produce a signal reflection that causes this problem
I suggest you pressurize the cooling system let it sit overnight pressurized and but a borecope inside the cylinder that is misfiring and check if head gasket is leaking. Or maybe is just a recall or service bulletin to update the ecm/pcm

I drove it 40miles in the Texas 108 temp and it’s clean no codes rn
So I went from a bad engine at 120k miles to a new resealed and new rod bearings engine with only 80k miles
Change the injectors from cylinder 6 and 1 and see if the code changes too

On my 2008 335xi with the N54, the misfire was fixed by replacing the VANOS solenoids all fuel and ignition parts were already replaced by the dealer.

never miss new content
Probably a cam sensor, crank sensor or something along the lines of a sensor/wiring fault
Pls do a detailed breakdown of the failed engine, also a turbo rebuild if possible.
Figure out the issue on the original motor then add bigger turbos & put it in something else. Something it hasn’t been swapped into before!
Wouldn’t it have been much easier and cheaper to take to the dealership and have them diagnose the problem and fix it?
New to the channel. I feel like it's a rush to swap the engine instead of trying to diagnose and fix the problem.

I'd like to imagine that since I have been driving BMW's for years now and I have a 2006 E46 M3 and a 2008 335XI N54 Modded to the gills (Around 730HP) that if I won I'd immediately turn off the traction control and burn a few donies right then and there in the lot! LOL. But I probably wouldn't because the character my father, my family and MY GOD has instilled in me would prevail and I'd just have to be respectful and not a total self indulgent tool! LOL! AWESOME CAR! AWESOME VIDEO! Thank you!
Same Stuttering thing happened on my VW, after a while my Turbo blew and it somehow affected the valves, i was told to either get a new engine or complete rebuild. Safe to say i am broke my car is now standing can’t afford to fix it and now without transport😅
Had Evan worried again. I love it 😅
Love the color: reminds me of Porsche Miami Blue.
Great job! This video was awesome guys! 😎👍👍
Awesome job as always guys! Kinda missing Mickey though.
I had this problem on my Audi S6. Dealer couldn’t figure it out. It turned out to be a solenoid for the cylinder deactivation.
Can’t believe y’all didn’t carry us along in the troubleshooting process of the last engine 😢
Dude this is amazing!! I’d love to see you tackle BMW’s infamous early 2000s 6 series. I’ve got a 650i convertible with the first gen 4.8, would love to see what you’d do to it!
An S55 rebuild would be so cool!
Transparency is key!
O2 sensors! Have the same problem on my n54 as we speak tip in was shuddering from 1800 to 2500 rpm, snipped the o2 sensor in an effort to change it and it’s even worse now till I pull it out
First and foremost, I must say you yous are the goats. I'm Bobby. I'm jamaica. I've been watching your videos for a long time now, and it's my first time making a comment. I dream of owning a car builbuy you guys, it seems impossible, but I still dream i respect everything you guys are doing. I'll keep watching for as long as you guys are making videos, and im able to watch Stay Safe. your's truly one of your greatest fans
Put the BMW motor into a JZA70, It will be like a new Supra. and it will pair nicely with the 300zx
i had a similar issue on my 2010 535i E60, found it was a bad ignition coil. so i bought a whole brand new set of coils, issue fixed... now oil leak again, probably tried fixing leak probably 3times...
That car is so beautiful especially with that hood open and everything looking beautiful lol
