Tearing Down the M3's Blown up Engine (BMW S55)

[@mortalityrated1495]

As a young adult, I would always get up on Saturday mornings, pour myself a bowl of cereal, and sit down for Powerblock TV. Two hours of mechanics going ham. That's why I adore this channel. It brings back the same feeling that I had as a young adult watching that on Saturday morning. Thanks for giving me that blast of nostalgia, Throtl. Very much appreciate it! \m/

[@michaelnoble7168]

I was the same way. So many good shows . My favorite of all time was trucks with Stacey David

[@jonleeg2120]

Powerblock TV was the move on saturday mornings!

[@makuakane7787]

The only difference is, Throtl actually shows all the steps of tearing down and rebuilding the engines.

[@seanwells9144]

If you have direct tv there is still new episodes of some of the shows like trucks and two girls garage etc on 281 motor trend. I remember way back when it was the speed channel or network.. and then before that it was something else but I can't remember what it was called .. it's been like over 20 yrs

[@kaminari8481]

They should finish my '79 C10 w/ 454 and 4L80e and it'd be just like Powerblock TV 😂

[@PositiveRate81]

Jedi engine master Quin should get the opportunity to rebuild the S55.

[@defkon99]

The throttle body has a water jacket for cold climates. Make sure to check those oil squirters, especially on #6 which could be the cause of starvation.

[@joeyjoejums]

A water jacket for the throttle body? Wow.

[@defkon99]

@@joeyjoejums Yea i have it as well on my 1993 e36 throttle body for M50 engine- so they been doing it for a while

I got a lot of thumbs up in some comments on this but what was the actual result?

[@cakeless8486]

Quinn , I really appreciate the way your explain the parts. I’m novice with car knowledge . You explain it in an easily accessible way .

[@JaroslavP]

Such a cool episode! Just when I thought that Quinn couldn't impress me more than I am already, he does this! What a guy! Kudos, man!!!

[@anzelcanete435]

Quinn's love for all things BMW is infectious (minus the DTM squatted suspension😉). Seeing him building an S55 and making a little drift missile with it would be awesome content for the channel and a chance for the crew to test their fabrication skills on new kind of project

[@JustEnufCustoms]

Rebuild it please. I've learned so much watching this episode. I would love to break down an engine find what's wrong and fix. This is so interesting to me. I'm having to do that now with my wife's 2.4l gdi motor. Timing chain broke so I need to yank it out the car so trust me this is so informative to me. Thanks crew 🫡

[@Dr_Wrenchh]

I still think it is a very slightly bent valve stem on cyl 6. That caused the valve guide to wear and also wore out the valve stem seal letting oil in there causing that weird misfire. Very likely happened when the stock intercooler failed and it ate coolant. I’d check all the valves and guides when you guys rebuild that thing🍺 Let us know that car drove me and Mike crazy😂

[@LarrySoliman]

this has to be the only answer.

[@clifbradley]

I think when it went low on oil, the heat built up and dried out those stem Seals. But the lobe on the crankshaft being so bad makes me think that the oil starvation was so bad that it was microwelding when the car stopped. I didn't see him pull the valve stems though.

[@Sublooge]

Quinn did a great job explaining his thought process while taking the engine apart and diagnosing it! I’m excited to watch you guys build this engine and see what you put it in

[@melo.lucas320]

Just had a idea: throw this engine in a E46 M3 with the DCT.......

[@asmahanumer]

plus Bigger TURBOS BABY!!

[@EmjayDTube]

You read a lot of people's mind bro. E46 M3 with a S55 Swap. That's gonna be a sick of a build

[@NicholasDugger]

Good find, I believe the reason why you are only seeing the issue on part throttle is the vanos timing of the cams. BMW STEP tech here.

[@trickysubject8563]

A 2002 restomod with this motor in it would be special guys. Converted to one large single turbo. Or a CSL Batmobile would be an awesome build. I’m not a BMW fan, but I’d love to see this come to fruition. Thanks Throtl, always fun and educational to watch. Tricky from England.🏴󠁧󠁢󠁥󠁮󠁧󠁿

[@phonetics8272]

Love the 2002 idea!

[@alenassereddine5088]

I would LOVE to see the rebuild happen. Especially with Quinn's master builder hands on it.

[@gateaccess818]

@15:21 jegs sells an oil pan taht straddles an engine stand. or you can weld 2 flat bars to the lower beam alllowing you to set a pan across the flat surface of the 2 welded bars.

[@Von-by8xz]

Quinn is awesome. The network should sponsor him for his choice of cable TV show and KZbin channel. Raw talent at its best. I'll always be a student in that class room .

[@kingBlon-D]

Please rebuild, the video has 14k likes!!!!! Evan mentioned, above 10k and they will do!!! Let’s go team rebuild this amazing engine please!!!

[@G60MM]

I think the pitting on the internal parts came from sitting for a few months. The engine failed in hands of the previous owner and the repair bill being for probably, replacing the engine long block, the owner left the car sitting until he figured something out. That exhaust valve stayed open when the engine shut off and the moisture creep from there to the internals. Then he just gave it as trade in, hoping for the dealer to not find out about the problem. Then you bought it.

[@EvoSteve89]

This is the exact scenario I was thinking 💯

[@erickquezada2642]

As a tech, this sounds about right

[@JK13A]

Seriously, you all could have just passed on this engine and not said a thing. Absolutely trustworthy dudes. Love this channel.

[@LardieBros]

Mike essa (with DDE) had oil starvation on similar designed block for the f30 340 motor on cylinder 6. It seems to be a common issue with high revving use, but he did make a fix for it after new cams

[@darylmorse]

The B58 engine is completely different from the S55. The problem on Mike's engine had nothing to do with this engine. This engine failed because of neglect / poor maintenance.

[@Mark-th1gn]

nice job taking it apart and getting to the conclusion boyz! Such a shame it was oil starved, now it had to come out and be disassembled etc, just because someone did not check oil lvl enough.

[@nautilus-salvo]

Impressed with the diagnostics and level of detail on this teardown

[@adammurdoch1708]

just going thru replacement of engine on my 115000Km n55 335i spun a bearing and put metal through all the rotating assembly. was all stock so was a surprise is costing me a heap.

[@shanefranksmitsdorff9092]

Shoutout from Cape Town 🇿🇦, awesome content👌🏻 As a BMW owner it’s amazing to see you guys work in a straight 6🤝🏻

[@SuperBigNye]

water defantly played a part in that pitting rust formed you guys drove it cleaning the lob but damage to the materal was already done from sitting.

[@patrickgarvin2570]

Quinn, you got all the tools and shop necessary to fab an engine stand to your standards. Viper casters and a hellcat catch pan. Get to it Brother!!!!!!💯💯💯💯💯

[@collindayley4049]

Yes, please rebuild! Love to see it drop into a cool rebuild down the line.

[@organicod2438]

I wonder if you could use a strong magent to hold the oil catch pan to the engine stand while you drain it. Yeah, Magnets, baby!

[@CD-zz4li]

All of you guys are very intelligent and I don’t think you would have went so far if you wasn’t going to rebuild it so let’s get it done guys come on yeah got the ability smart and it’s very entertaining. Keep up the good work.

[@ChristopherKohuwsky]

You guys should really rebuild the s55 engine straight facts 💯

[@infamousnobody5172]

Definitely build the motor. I like when you guys mod the motors more heavily over body stuff. Maybe swap that built motor into a base 3 series and make it a sleeper, that would be cool.

[@TSM13]

There is a known issue with the S55 where the exhaust cam isn’t torqued down correctly from factory and it “floats”. It’s usually most notable by a rattling sound on a cold start that goes away. Could the exhaust cam have just become “loose” towards cylinder 6 which caused it to wear more? A previous fault that has just got worse over time? My M2 Comp (S55) had it and BMW replaced the cam and carrier under warranty.

[@Ooogs-h1i]

That's what I was thinking. Same happened to my f80 but when I inspected the cam lobes they all looked good so I just bought new bolts and reinstalled making sure to torque to the correct spec and it solved it.

[@Tyler_Suarez]

Definitely do a rebuild! haha love how Rickey is a genuine bmw hater lol but i love a Quinn engine teardown/rebuild episode. So much knowledge to be shared!

[@fgj8379]

A good condition S55 with just studs is capable of pretty decent HP. I think since the B58 and S58 have come out, the S55 has taken a back seat in most people's minds because of how easy they make power. With rods and pistons, this S55 is going to be a monster. I'm excited to see what they put this in.

[@timothyedwards9666]

Of course you should rebuild it, great content and the final result will be whatever you want it to be a MONSTER

[@thecraftyproject4347]

Send it to Daves Auto Center. Theyll figure it out in a half hour, and itll be a cool collab.

[@virgilowens5654]

Can we get some info on that silver s15 yall have in the back ground? That would be awesome to see get built

[@RickyMei-b1i]

If you rebuild it, change out the OEM crankhub to a 4-pin or 2-pin keyed crankhub! Since, you're already taking it apart and get an upgraded valve cover! Those are the main concerns for the S55 platform

[@RickyMei-b1i]

SINGLE TURBO THIS!!

[@SNIPE98]

BTW Carbon Buildup is a common issue for S55, where fuel is sprayed directly into the combustion chamber instead of the intake manifold. These deposits can reduce airflow, performance, and fuel efficiency, and cause rough idle, misfires, and cold start issues.

[@ncalimike]

Rebuild it! Then put it in my 2016 F30!!!! Love you guys!!!

[@alexmonty1017]

Absolutely you guys have to rebuild it. Me watching while owning a B48 😂 Anyways, tell me about that S15 in the back.

[@SamPonjican]

Maintenance on ///M Products is so crucial. I loved my e46 M3 back in the day but that performance comes with additional rigor with maintenance. Very unforgiving. Such amazing machines to drive, but do not mess around when it comes to maintenance!

[@kevodean]

everyone please like this video, a stage 2 s55 built for 1000hp cost close to 20k, would be a waste to see it sit on a shelf, i wanna see this thing get installed in a e36, they got the resources to make it happen! LETS GO BABY!

[@robsparkes76]

Quin needs to rebuild the S55 for big power, then it can be dropped in the Prowler as a straight six is ideal for the narrow chassis.

[@mllipperdt]

Not surprising that the camshaft is bad. I bought a brand new Chevy years ago, it spent 92 days in the shop out of 6 months. Thankfully Texas had a lemon law. The camshaft was bad in it also.

[@benjiepale1776]

You should build that beautiful engine and again, like what I said before, paint the floor. The floor of the shop. Paint it. It will look cleaner and beautiful. Red or green floor color is good.

[@JK13A]

How do you buy a car like this and then just not reliably change the oil? Wild dude. I have a 2014 Mustang GT that I bought last year with 33k miles on it. I changed the oil after a years worth of use and weekend driving of 1.5k miles.

[@Alex-fo1rx]

I'm sure the misfires are coming from coolant. There is a leak somewhere. Those air to water intercoolers are notorious for leaking, all brands related.

[@shogan130013]

[@leekay07]

Not sure the miles I saw the other video and commented it was the valve shaft worn. It is a wear item and kits are sold. its like 2k for the kit. And 8 hrs labor.

[@cristiancarello1043]

[@Bill_Hartnett]

You know they make oil pan especially for engine stands right? It goes right over the center & has a channel for the beam so it doesn't move or fall over. Sunex Tools 8300DP so you don't even have to look it up $40.

[@johnnygoesfast9397]

TBH...isn't it more satisfying fixing things than slapping parts on a car??? These are Throtl Gold

[@SolivagantJourney]

To me, it seems most likely that it was low on oil or had old oil that wasn't lubricating properly that caused the lifter to wear first and the worn out lifter caused the cam to wear unevenly. From my experience, it's usually the lifters that fail first

I would say it was a bad turbo actuator. It was causing excessive turbo lag , under heavy load. When your reduce exhaust flow engine can't push exhaust out fast enough.
