BMW E46 Engine Reassembly Part 1 DIY

- I began my rebuild when I did a compression test and noticed I had poor compression in cylinders 2-6 (about 142 psi, the bottom of the service limit). Cylinder 1 had 160 psi. A leakdown test showed leakage into each adjacent cylinder. Of course my engine also had the oil consumption problem (1 quart every 1000 miles) that every M54 engine has, which is caused by the oil rings which wear down prematurely (the M52TU used different oil rings which did not have this problem). There was also coolant loss, which I didn't measure precisely.

i'm from Brazil. I would like to thank you wholeheartedly for everything you do for us, the owner of BMW. I have an E46 325. I learn a lot from your videos. Even without knowing English. just for your visual explanations. I did everything on it. Now I'm making the engine completely at home. I had never done anything like that. But thank God and your videos, I'm doing it. thank you very much, you have no idea how important your videos are to me. I am using a translator to send you this text.
Man these videos are gonna be very helpful when i rebuild my m54 after it dies. It'll be my first rebuild. Thanks for making these.
How is your m54 now 2 years later? Mine is still good after 18 years and 261.500 km, I only had to change the ccv,the intake boot, a leaky radiator and rebuild kit in alluminium for my disa what about you?
Hey Jason, this is a great video and the one thing I enjoy is that you cover the things that went right and the things that went wrong. Anytime we wrench it is an iterative process and we hopefully learn from our mistakes or wrong assumptions. You handle it as a teacher and help us all learn. Thanks for the effort!
You are truly a proffesional both practical and pedagogic teaching..I am a teacher in carmechanic and I bow to you..you are just great!!!
50sKid, great video, but having built various engines for 40 years a couple of things I would have done differently. First when cleaning the cylinder bores of a freshly bored or honed block ALWAYs use engine oil, not solvent. The oil will float any debris off the bores. I obtained a brand new Toyota OEM 22RE short block from the dealer for my pickup and disassembled it to check all the clearances...you wouldn't believe the dirt that came out of the bores using an oil soaked lint free rag! Also when installing oil seals in their carriers or a timing cover I use a light skim coat of gasket sealer on the outside of the seal...Toyota black FIPG is the best...NOT RTV! The seal goes in the housing easier and it won't leak around the perimeter. Finally I wouldn't touch those Chinese eBay master kits with a ten-foot pole...too many unknowns in metallurgy and as you saw the rear main seal was crap. Just my 2 cents as a fellow shade tree wrench!
-Make sure to safety wire or weld the oil pump nut!- Would be a shame to rebuild that pos again.
M52B28 owner here.
loctite saves the day. This is a cautionary tale for those of us with cheapo torque wrenches
Next week I will be watching this video over and over again! Thanks a lot bud very good job man!
Good video , small tip for assembling piston clips is to put it in like you did but have the endsticking out next to the dent , then use a small flathead or one end of a c-clip plier to lever the clip in to the grove.
Man I learned a lot from watching your video’s. Overhauled my head on my 525i and changing my timing chain guides as well. Installation tomorrow wish me luck lol. Would’ve never attempted this project with out you , thanks again
Hey, so, I received two sets of those same Glyco bearings (6:45) and had the same issue with both packs! Be sure that if you order the Glyco bearings, whomever is shipping them CHECKS THE PARTS! The company I ordered them from replaced my order with OEM main bearings for my rebuild. Hope this was helpful.
Glad to see it finally coming back together!
Reusing bottom end bolts… you and I could be friends.
So far so good... it's been, what, 3 years or so. 😬
@@50sKid I’m 100% on your side my man. If it can’t take me putting it together with a hammer I can’t expect it to let me bang the limiter.
@@justinarnold6044 ha!
Wincing every time he tapped the oil pump locating pins with a raw steel hammer
Can't wait to the start up day!
I see you working very hard
Do you think you could do a video on replacing the rear wheel bearing? It seems to be a massive pain, but you always manage to clear things up for me.
Edzgarage has a great video on doing the rear wheel bearing. I wouldn't do anything different than he does.
I would have loved to have seen a before and after rebuild results from a dyno.
Awesome job again
man i miss your e46 videos
Excellent work man!!
Did you have to send the new pistons to the machine shop so they can match the piston to cylinder wall clearance?
+1 thumbs up. Not many bmw engine build video's on youtube. Thanks i need all the tips i can get for my rebuild
Love the adult ads on your table. Good video overall.
It was a free newspaper lol
see told ya it always comes back to old fashioned way using Plasti guage ..can't beat experience
Great works
The brass .010 is nonferrous for setting the stator on small engines
Aha, thanks!
Can I put a 325i head on an m54, how do I measure any differences? Thanks for feedback
silly question. If I have green bearings, and the crank has been measured but is within tolerance of the white bearings, does that mean that I have to take the white bearings as new ones instead of new greenes?
Hey what is the torque tool link information to purchase you used in video tightening the lower half of crankshaft. The tool made a beeping sound when the Nm was reached in tightening process. Thank you. I have the regular standard versions i would like to get that specific torque tool. Tyrone inquiring.
Why are you rubbing the bearing surface with your finger?
Thank you for sharing your Veido lots of detail. Good job but one question your engine is M54 how much different is it from an S54 engine .
The bottom end is very similar--I mean, an engine is an engine at the end of the day. But it's made from cast iron instead of aluminum. The cylinder heads are very different though. The S54 does not have hydraulic lifters.
Hey 50skid. Working on a rebuild m54b30. I been looking at the piston rings sets but I notice you have the 3rd oil rings separate. Where did you bought just the 3rd rings?. Or if you bought the whole set of the m52tu which model and year did you use to buy the piston ring set. I'm planning on using the piston ring set of the m52tu and reuse the 1st ring from the old pistons. I measure them and they are within specs.
You don't have to get rid of the plasti gauge from the bearings. I've built 2 ls3 engines and its never hurt it will disintegrate
I realize this is old video but I have a question. I heart about the m3 needing rod bearings at 100k as a maintenance e requirement, I see everybody just popping in a set of bearings and thats it, ggod to go. Is it advisable to replace e the bearings on m54 engine without grinding the rank ot rod caps assuming that the 2 surface aren't chewed and do u just pop in a set of off the shelf factory bearings? Thanks for the help and prompt answer! Happy new year
I can appreciate your logic for reusing main cap bolts but why were you reluctant to extend that same logic to reusing connecting rod bolts? You indicate in your video that the max torque was 45-Nm which I would think is below the torque that would result in stretching the bolt?
What bolts did you use to mount the engine onto the engine stand?
I clicked on the link you provided for the oil control ring set and eBay shows nothing can be found. I’m currently rebuilding my M54b30 and need those .5mm oversized oil control rings. Do you know another place I can go to?
Thanks in advance
Sorry, no. You’ll have to buy one set of m54 rings and one of m52tu and mix and match.
Were you setting the end flot or axial movement when you used the pry bar and soft malket? Is there a need to measure this with a dial inducator or feeler gauges?
So n the crankshaft and connecting rod bearings, do not put any engine reassembly lube on the backside of the bearings during reassembly???
David V fuck no. You’ll spin a bearing doing that. Never oil the back of any main, cam , or con rod bearing. I prefer engine assembly lube to oil. It will stay in place longer. Oil tends to run off eventually. Also it won’t effect the oil. You can confirm this with an oil analysis
With rsgards to drilling deth for inserts what would happen if you set your deth adound 31mm..if ths bolt passes thdough the insert it will just thread into exisiting threads vs tapping the way down creating possibility for insert to be threaded further into block and then fail to hold torque?
what if your new threads don't line up exactly with the existing threads? Best to drill as far down as you can
50 skid whatdo u think couldbe wrong with my e46 my number 3 cykinder shows no compression all other are 180 compression ty

My engine has 135psi in all cylinders, I've noticed that cold startups would make the engine knocking sound, like someone using bad gas, would misfire horrible when cold.
What did you do to fix this
nice vid man, but you ordered thee wrong bearings! it must be H023/7 STD instead of H948/7 STD.
Yes I was trying to order "green" bearings to replace the green bearings that came out of the engine. Ecstuning had the bmw part number for their green bearings but they turned out to be wrong, of course.
I've experienced ECS application errors myself. It happens.
Does that affect the crank or do any damage if i installed the wrong colour ?
hope you checked the crank endfloat
I have subscribed. I appreciate this series of yours my brother. I am on the verge of doing up my 320i 2.2l engine. Before I do, please advise me if I can be able to incorporate the M52TU oil and piston rings to my ordinary M54 engine in place of those M54 ones. Also, for the gaskets, should I also look at the M52TU ones as well? - as from what I have gathered, they last a lot longer. What other replacement parts would you recommend that are more durable for my rebuilt engine to last longer than the OEM.
You should be able to use those rings, yes. The gaskets weren't any different on the m52tu
Thanks for the lesson. What is torque applied?
Hey! Love the videos! Could you tell me what brand the digital torque wrench is please? Thank you :).
Cant spin crankshft bearing caps on correct side...any ideas what problem might be?I am replacing crankcase and using original internal engine parts (crankshaft and main bearings). The original crankcase had green paint dot and replacement crankcase has yellow dot. I was able to spin crankshaft with ease with engine belts and pulleys but after relocating crankshaft I can no longer rotate crankshaft. I have not polished crankshaft or changed bearings. Do I need to do this? FWIW... I placed crankshaft and main bearing back into original crankcase and was able to easily rotate crankshaft. The only obvious differences is that the original engine block has green paint on it whereas the newer block has yellow paint on it. I have ordered yellow bearings...Hoping this works....ThanksPS....I made sure to install all the bearings in the correct orientation and placed bearing caps in the correct locations.
The answer...when the engines are manufactured...tbey are aligned bored witb the bearing caps installed..the ock and caps are unique to each engine so as in my case tbjs block did not come witb any caps. I am using the caps from my original block and that is why their is binding. So I have to have the new block with its new caps aligned honed as one unit and they mah need to vrind the caps down to bring everything in spec....fortunately I have my orifginal block and they can copy the specs
The problem was that each engine block and main caps come designed as one unit...The main caps are not interchangeable....I had to get the donor block and main caps had to lateral bored or whatever in order to get crankshaft and main caps to fit together.....$750...I had no idea...so if you use a different block...make sure it comes with the main caps...
Mate I have GLYCO and that are solid on on side.?1
Ill being habing a problem whit the timing
nices vids as always
Don't want to school you but..King Bearings or equivalent will work better😁
How much torque do the M52 cylinder head bolts carry overpacking
40nm + 90 degrees + 90 degrees
Did you forget to place the crankshaft brackets to engine block or do they go on later??
@50:52, he mentions in writing at the top of the screen he forgot to put them on and puts them on later.
Where Did You Get Your Rebuild Kit From ? I Have A 02 325i E46 And I'm In Desperate Need Of A Good Rebuild Kit
ebay. The only one I could find. It was only an okay kit--the gaskets sucked. The pistons seem to be alright. I would look into your local parts houses--they have connections at parts warehouses.
50sKid Alright Man Thanks I Appreciate It ! Would It Be Too Much To Ask If You Could Be On The Look Out For Some For Me And Just Let Me Know?
@@50sKid What is the overall quality of the all set? I am concidering buying the same kit but I dont know what is eaxactly the quality, I am little bit worried.
Are all the victor reinz head gaskets 1mm thicker?
No Victor Reinz makes both sizes of head gasket and they are 0.7mm and 1.0mm in total thickness (not thicker).
18 months later. Is this engine still running strong? I am rebuilding my M54B30 as we speak, but I have my doubts about this ebay rebuild kit you linked in the description. I mean: 500$ for everything, pistons included, sounds dangerously cheap.
Yeah it’s doing great. Drive it every day
thanks for the reply. And thanks a lot for your videos. I was disassembling the engine with my computer next to me, to check out your videos when I got stuck or had my doubts on something :D Just one more question. What brand were the parts you got with this kit? I mean: even that you still drive your car and it's running fine, I can barely believe you can get quality parts for that little money. Are they branded or is it "made in china" pistons?
@@dokterkarel En rijd die van jou ook nog?
@@Salty_Legionnaire 12 000km verder en still going strong. Zelfde ebay kit besteld met daarnaast nog een waterpomp, ketting + spanner/geleider, en M52TU olieschraapringen. Mijn cilinders zaten net buiten de tolerantie van ovaliteit, boring was 83,97mm op een punt, maar heb geen drama gemaakt over 0,02-0,03mm. Draait netjes en verbruikt geen olie. Enkel de Victor Reinz kopbouten heb ik laten vallen en vervangen door OEM. Check youtube maar eens ivm de M54 kopbouten van VR, trekken op niets.
If a shop rebuilds a engine like this how much would the total cost be ?
Having recently purchased a 99 328i to rebuild/restore for my daughter, I have recently started watching/following your videos. Being a long time engine builder, I will say I usually cringe a little bit when I see someone final torque a long beefy crank like a i6 from one end to the other instead of starting with the center and working your way out. Is there a reason you did it one end to the other? Great videos man!
What oil do u use when u do ur oil changes
5w30 synthetic
50sKid what brand though?
also what do you think about motul, vs bardahl, vs Castrol, vs mobil1?
So now not using inches and etc like USA people like.. Millimeters, centimeters are more accurate than inches and etc..
milimeters are NOT more accurate than inches. Both systems are just dividing up a certain measurement into smaller measurements. Accuracy depends on the precision of your measuring tools.
Oh heck fuck yyyeah brro0o!
Block looks brand new!
Check my video out, mine looks like scrap on the outside 😂😂
PS I gave you a mention in my videos
thanks man, i'll check 'em out
You put made in china products in your rebuild? You know that they only pay lip service to see international standards right? You cant beat quality machining. Then you double check work done by American tradesmen on your block? Amazing, but its your car.
You gotta understand that:
a) there are no american made aftermarket pistons available for an oem M54 block (only for the S54 which is the M3).
b) I was making a series here that is supposed to show other people what they should do with their builds and it's always a good idea to double check the work that is done by your particular machine shop because there are bad ones out there. I've seen blocks that were not decked flat, etc.
c) six OEM pistons at $350/each plus all the rest of the money I spent on this job would have cost more than the car is worth so Chinese ones were the only option available to me.
d) everything turned out great and the engine is going strong.
The little bibliography regrettably charge because lyocell findingsinitially remain regarding a nippy aluminium. enchanted, crooked gearshift
Broder u are jinos.
Dude you're making an engine rebuild video and you don't even know how to put the god damn thing back together?
That's what's great about the video. He is learning as he goes.
