REBUILDING MY WRECKED 2023 BMW M240I | PART 5 I Am SOOO LOST!

[@BackYardBoyz]

Do we repair the engine or go full out and build it to handle 1000+ hp?👀

[@TNT-ml1ll]

Build it to 1000+ hp

[@paulsprojects1]

i think your first idea of the slack oilpump chain is probably your best bet, it looked too loose and would cause a noise

[@josephhaley1443]

Yes sir that’s right

[@adamwhitaker9579]

I genuinely don’t think you have an issue, it’s probably the slack in that chain, and the sound deadening allowing you to hear it more. You’ve gone down a rabbit hole and like you said got a bit lost. You have to think logically about it. See if you can find another 240, take that sound deadening off a see if it sounds the same first

[@dedan2]

Boosting this comment. Find another 240i first.

[@prigatdenuci]

I agree. I think the chain is way to slack.

[@daxxr2532]

I own a 2023 m240i, it does not make that noise

[@Perceni]

I agree, check another similar car first

[@mikevog4621]

You can get that oil chain tighter by putting shims under it, BMW sells these oil pump shimms that come between engine block mating surface and oil pump

[@kenrossaukrsa]

Maybe it’s the Piston gudgeon pin.. take each piston to tdc right at the top , in the spark plug hole , stick a screw driver or a solid rod that fits down there and press hard down once on the piston , you should hear a clunk noise if it’s faulty

[@bimmerflex5526]

Yes Tim. Excellent progress. U.K. says please don’t give up. Cars new, oils perfect, plugs to. You can do this with your utter determination, dedication and patience. It’ll be phenomenal content. Perfect once completed . U.K. supports you. 🇬🇧

[@hevendranarayansamy2793]

Stick a camera down the spark plug holes to see how is the condition of the pistons

[@AnontheGOAT]

That’s what I was gonna say. He needs a bore scope cam to see the condition of the cylinder walls.

[@hevendranarayansamy2793]

@AnontheGOAT yeah maybe there's a bent rod causing that play on the crank. I'm no expect either. Just suggesting

[@louiswetzel1578]

@@AnontheGOAT If the cylinder was bad, the compression would not be so good like this.

[@AnontheGOAT]

@@louiswetzel1578 I’d still scope the bore just in case. Could be a bent rod. But tbh, I don’t think it’s anything to do with the actual engine itself.

[@Poseoptional01]

Tim’s a beast… I remember Tim doing full rebuilds in a plastic covered car port and a frame machine!!! Salute big dawg!!! 😮‍💨🫡

[@robtheman]

Tim is the best car rebuild KZbin channel available. He always gets them finished! And they are always bad ass

[@zildog]

Nope... that award goes to M539 Restorations. Sreten is an absolute BEAST among the best BMW mechanics anywhere.

[@alj7094]

Ah man after all the sh1t you done the damn knock is still there I’m feeling exhausted already just by watching 😂😂😂 I hope everything goes smoothly when you’re pulling the motor. I love this series because I own a 2023 M240i. This helps me to understand the platform even better. Good luck man.

[@MASKIM01]

Bro, that ukrainian was lit, we definitely need some videos with it 🙂😂 but this b58 is really getting on your nerves 😬

[@Bnm-fk9fi]

Loved watching you use the screwdriver method to locate the noise. I was about to comment suggesting just that. We used the good old screwdriver when I was an apprentice a long time ago on electrical motors to pick up dodgy bearings. Worked then and works now 😀

[@osmansyed7262]

Brother your good at what you do! I’m 100% sure you’ll figure it out. Whatever you do, don’t quit! Your an inspiration to the younger viewers of your KZbin channel. Make this one of the craziest builds on your channel till date. Something crazy like an M2 CS Track Spec🔥. You’ve come so far with your Journey on this one, might as well do a few extra miles. I’m a long term viewer of your channel and enjoy watching your car transformations. Keep up the hard work! 👍🏻

[@RobertoRodriguez-px5sd]

💯💪🏼🔥

[@crherniman]

Does anybody know the correct amount of slack on a b58 oil pump chain? That seems excessive.

[@TehNouk]

Its normal. Oil chain are always loose, if they do not have tensioner

[@qpoole90]

Amazing job with this video and the story telling..this is a great series so far. Cant wait to see how this and your other builds turnout..keep up the great work Tim!

[@chrish.538]

Doesn’t sound like a bad engine tho. With the insulation installed, listen and compare to another b58. Definitely no need to pull this motor mate 👍🏻

[@aelaan12]

If you see the sweat, tears and still have made only progression to the fact the "knock" is still there, and after all this you are determined to fix it, that shows character and willing to learn. Could the crank shaft be bent ever so slightly? Only time will tell. Good luck in pulling the engine, look forward to the next videos. "It is a hard knocked life"

[@fred420]

Great video! Can't wait to see what the deal is!

[@maz872]

Full respect for you 👊🏽 bro you’re honest and we know you will fix this car. That’s why we all love watching your channel

[@Poseoptional01]

Big Facts 🫡

[@toppedout4552]

I’m a bmw master technician, the oil pump chain is completely normal, there are measurements that can be taken but from what I’ve seen im happy this chain is fine.

[@Delight.AutoCRAFT]

That plate that prevents lateral movement is called a "thrust bearing", thank you, you're welcome

[@chilltify]

Maybe lose chain knocking on chainplastics

[@The330ic38]

Hello, I think your problem may be due to the oil pressure, I don't know how the B58 works in this case with the chain tensioner, but having an inadequate oil pressure would stop tensioning due to pressure and make a small noise, I don't particularly think it's the crankshaft, connecting rods or crankcases, I think the problem is oil pressure.

[@xLeeVine]

Hi Tim! So i heard there is that typical problem were the oil pressure created by the oil pump is to low in idle rpm. That leads to the problem that the hydraulic chain tensioner does not tension the chain proplerly. That would also explain why it goes away after slightly reffing it. The oilpump rotates faster -> higher oil perssure -> hydraulic tensioner fully tentions the chain -> no more noises. And it would also explain why there is no noise while cold starting: rpm is typically also higher than normal idle rpm. (You said there was no noise during cold start and reving on your ig story). Greetings from Germany.

[@abeliekitishimik5613]

Please dont give up! I like your content with this BMW. I waited weeks! I thought you gave up, glad you didnt. Good luck sir!👍🏽

[@warpspeedracer]

Great video. Thanks for sharing the journey. Definitely, unexplored territory.

[@unspecific2610]

Love that youre back to fixing the M240I! Interesting to see the ins and outs of the car!

[@vltrrr]

All of those new b engines sound like knocking without the covers😂

[@KlemenJereb]

Brooo, I feel so bad for you!😐 We bought a car at an auction...it wasn't this nice, it was an Opel Astra 1.6 CDTI, a diesel, and it had a horrible sound. We thought it was a chain, and we opened it up the timing chain guides were all messed up, so we replaced everything except for the timing chain gears, because they looked good and we wanted to save some money🤦‍♂️. The sound came back as soon as we started it.😢 We even replaced the flywheel, nothing helped. We did the chain again, this time with the gears, and the sound went away!🎊 One of the gears had play in it, and that's what made the knocking sound. What I'm trying to say it, don't give up, you'll figure it out eventually!💪 Greetings from Slovenia!🇸🇮

[@arnaldotav6709]

You can fix anything, I can't wait to see that engine out and repair.

[@johnsortino]

I know you did a compression test, but to be even more definitive it might be worth considering a leak down test to verify valves and rings are good too.

[@trevoralexander8696]

Hi check the big ends on the crank shaft the crank is steel the bearing are a soft metal so rubber down the crank shaft so you take off the soft metal off the hard crankshaft fit new big end shells job do

[@bluesky8872]

There is always a first time for everything! You’ve got this bro. I am changing my BMW M135i (euro) motor on my driveway, no garage!

[@maneycb9]

Yup probably the slack on the pump chain. Full send it broe

[@angelcelis9090]

Yessir 100% the oil pump chain slapping around in there

[@erwin2844]

tim, i am praying for you to have a decent workshop. the current garage is too small and congested working space😅😅

[@bimmerwrecker1513]

Man I do the bmw engine rebuild every day, I told you that rod knock doesn't sound like that. The lifters, injectors are making loud noise especially if the car seats Start the car and drive. Check all accessories and belt.

[@arectical3744]

Like i said in the Tiktok comment. I reckon it could be the torque converter due to no oil in the gearbox before.

[@stacyl8627]

Pull off the piston rod caps, push the piston toward TDC to give you room around the crank shaft. Take the vernier caliper and place it on the crank journal like your taking a measurement of it, slowly rotate the crankshaft and watch the measurement on the screen of the vernier caliper it should stay the same throughout rotation of the crankshaft. If the measurement goes up or down then you know that the crank journal is “egg” shaped and not perfectly round. This will help eliminate replacing the crankshaft or just replacing the piston rod bearings.

[@duztman7460]

BUILD IT TIM YOU KNOW YOU WANT TO !!!

[@bmwgary]

Sorry brother - what a chore to still have the knock. Hoping some miracle happens and you don’t have to pull the motor. You have huge patience & grind always - great things will always come your way with your determination. Good luck getting this part behind you without breaking the bank

[@dexter1944]

You know what It would be good to watch you DIY this engin make complete video best of luck...

[@Frazzo420]

It’s either the oil pump slack or the flywheel/ transmission. No way it’s a knock. You pulled every bearing and they look new. Can’t be a knock.

[@AnontheGOAT]

I was gonna post this - flywheel noise probably. My E63 has a dual mass flywheel and it makes quiet the racket lol. But it’s normal.

[@piovo1]

@@AnontheGOATthese are a ZF 8 so torque converter so not the same sort of knock but the impact could have damaged the flywheel.

[@AnontheGOAT]

@@piovo1 ah good to know.

I've been a new subscriber of your channel for couple of weeks maybe fiew weeks now and find your channel Interesting to watch, your making that engine dissembling look so easy I'm surprised that this is going to be your first engine rebuild man but good luck with it guys and looking forward seeing more of these videos man!..👌👌👍👍💯💯💯

[@ishvahkairav8498]

I'm not sure, when you mentioned that chain for the oil pump was loose and sketchy, i kind of think it may be that cause you've checked the pump but maybe something broke higher up that maybe isn't able to be seen from where you looked so i wouldn't rule out the chain

[@nandofsousa]

Check the flexible tube from the exhaust! I had a bmw make some weird noise and I discovered was the flexible tube broken

[@ThomannClaeys]

What I would do is pull the valve cover and look at the cylinder walls, if they look fine, put the engine back together, make sure it kinda drives, and just rev it out when you drive it. Give it an Italian tune-up.

[@Loud.Performance]

I'm convinced is something in the gearbox. Torque converter maybe.. Considering the impact and no oil in the beginning

[@AnontheGOAT]

Could be the flywheel.

[@castle_made_]

Been there done that but the headaches give you the knowledge to grow 🔥

[@kuruption1983]

Dude! all the best to you! Admire your passion and determination to fix this.

[@momchilmestchiev1583]

Torque converter noise, had the same with my m135i

[@damonwood8413]

I think you can borrow an engine hoist from NAPA, Also you may have been able to use an engine support bar to lift the engine up a bit.

[@pasha7015]

love your videos man, saving up to buy my own salvage BMW 😬

[@brianratliff3845]

Make sure your torque converter bolts are tight or flex plate is loose or broke had some ford fusions break Flexplate

[@TNT-ml1ll]

Yoo!! This channel is better than Goonzquad.

[@EldePHX]

Goonzquad is trash

[@ozairahmad1683]

I always was

[@Need4Built]

Amen brother !

[@brianfalconer217]

Noise definitely from bottom of engine, one thing could be that oil pump chain, would have to see another one to be sure, if the sump was damaged it could be one of the con rods hitting off it

[@viorelluchak3709]

everything will work out 👍 good luck!

[@ugr_acura3914]

It could be the oil pump making the noise. Or it could be loose timing chains. I personally would start with the oil pump as that’s where the sound is coming from in that spot.

[@youseficlipz2012]

the loose chain is most likely the issue . your going to have to shim the oil pump in that case

[@Youtube_executive999]

My new favorite channel on KZbin . Good vids man, wish you all the success man 😎😎👍🏻

[@danisohshang7079]

One thing when you have engine noise, don't think too much just find what it need..

[@njandina]

I think it’s tension pulley, sometimes it’s give that knocking sound

[@benjamins6549]

Maybe Check the Timing Chain before rebuilding the engine ?

[@LetsWorkBmws]

Bmw tech here, that sound is from the oil pump, those b58s till have this issue

[@eQuASiANXane]

Go on lad. Good attitude Tim an remember every day is a school day! Also, sounded like some sort of chain slap to me

[@duffydon1741]

Damn!! Such top class content, damn!!!

[@shumanimushavhela2152]

As always your videos are lit . I remember doing that to my e46 m54 engine that had a bearing knock. The chain looks stretched or loose perhaps that’s the cause or it could be from the main journal rod. All the best with this puzzle, I am watching from South Africa 🇿🇦 😊

[@UmKa_38]

oil pump chain is to slack, it need an tensioner. look on the webparts to confirm

[@soopermarkus]

I really hope you paid attention to the orientation of the bearing caps. You didn’t say anything about the directionality of them in the video. The caps can only go back on one way, matching up the numbers stamped on the sides of the cap and rod. The main cap is directional too.

[@cass96100]

Maybe a timing chain tensioner

[@deanthielamay6917]

This guys should be on 1m+ subs!!! legendary channel no doubt 🔥

[@juanhernandez-gk2ov]

love the video bro don’t ever stop

[@vp2395]

I can't wait for next episode of M240i !

[@newagetemplar6100]

Beemer Oil pump chains are all like that , which honestly seems rather crap , If your going off number 1 cylinder being at the back and the noise coming from front 5/6 then no idea. There’s nothing up front as far as I’m aware. If we’re at the bell housing end then dual mass issues or torque converter . Maybe a bent rod or damage due to bad injectors . Does sound like a rod is hitting something , maybe piston squirters bent and catching the rod unless it’s transferring from the top down to the sump . Ps always grease the oil pump internally , helps it prime so no oil starvation on startup .

Yo you got this full send. You’ll make it happen brother;)

[@uksa007]

Tim, Did you figure out/fix the oil pump chain slack, it seems way too loose? At low RPM it could be flopping about making noise?

[@BulliKid]

5-50 oil I’ll fix your issues

[@dieselstud2k6]

If you can read the oil level when trying to measure then the oil pump is ok. 2020 B58 TU oil pumps go bad I went thru it in my M340i

[@Bobwa2008]

Fix all the issues with the car and worry about this Fantom noise last 😊

[@BrunoGomes-nr8yi]

Simple, unplug spark plugs coil, one by one, if engine noise stops there's the cylinder number problem.

[@bimmerwrecker1513]

check catalic converter!!!! some times in accident it moves

[@joeyblack6492]

It’s the timing chain producing that knocking noise

[@geraldo.m]

i think it is that play in the chain

[@kennethomale5604]

After this build, the student will have surpassed his sensei (apologies to your dad 😆 )! Well, maybe not but you will have grown a whole lot and so would those of us following you!

[@davidscaife4312]

You need to start measuring journals and clearances

[@HG.Emmanuel]

What is the condition of the Valves, maybe you can check them by putting a endoscope trough the sparkplug holes? Then you can check the pistons aswell.

[@Project2gen]

It almost sounds like that front oil drive chain whipping around

[@shoaibjalali8689]

Check the crankshaft pulley/bolt

Bro get some shims from BMW and tightening that oil pump chain up. That is where the knock is coming from. Do not change those rod bearings.

[@lucianofrench1923]

The problem was the one side of the thrust came loose and was spinning with the crank. Measurements are correct

[@suhailmoola6157]

Most BMW’s after accident generally have tension issues that make it seem like engine problems. Don’t think you have a fault with Rods, something smaller
