BMW M30 Rebuild

[@benweber3615]

couple tips, get head professionally checked always!! never set down a head with camshaft in it on the valves. they could bend. always set it upside down. clean fluids out of head bolt holes! if left in the hydraulic pressure will give you a false torque setting and loosen later. use new head bolts! old ones are stretched. after assembly rotate engine by hand to double check cam to crank timing. valve interference means new engine. use copper exhaust nuts. upgrade to 4 pintle ford injectors

[@Feledwards]

one of the best motors ever made. I have almost 280,000 miles on my M30B34. Motor still runs strong.

[@RobynTapps]

Feledwards i have about that on an m20 :0 420,000 kms :p

[@suntzunikola2917]

RobTapps88 I’d take a m20 over a m30 any day of the week

[@RobynTapps]

suntzu nikola i have 3 m20's... and an m30.

[@suntzunikola2917]

RobTapps88 nice My e30 has 93k original miles on it

[@RobynTapps]

suntzu nikola my m20b25 has unknown kms.. one b27 has 350+ thousand and the other has 420,000kms the b25 is for a stroker build

[@Bmwfreak68]

It's so much fun seeing those rebuilds. Take care of that beauty.

[@tgamber]

Thanks! Will do!

[@scottmcphee7730]

Your amazing for posting this! My 1992 E34 535i hit 320,000kms last week. I'm sure it wont be long until i'm doing this too!

[@kenxiong6830]

Still a great reference after all these years

[@benweber3615]

Not doubting your mechanical knowledge. Just wanted to add a couple things for someone using this video as a guide. Pro checked head will also find bad valve seats and cracks you may not be able to see. I always rotate engine after timing belt change on m20 engine. 10 seconds of free motor saving insurance. Valve springs can rotate the cam after head removal

[@SladesVWBeetle]

Nice Job! Good Video! I noticed some oil leaking very "Slightly" from my head at 180,000 miles now. Between number 5&6 cylinder on the passenger side. Runs down past the block drain plug. I don't know if I have to change my head gasket yet. But if I do, this was a great video to see. I never worked on one of these engines. So I don't know if I should be alarmed. It is very slight, and I only noticed it because I was trying to find my drain plug on the block.

[@syedashiqshah2504]

Although this is an old video and the uploader has done a great job sharing this. If the head has pitted ports like that. I would send it off to the machinists. Also like someone else here has said, get the head skimmed, machined off by professionals. I would look into the pistons and Valve stems too while i have this much of an apart with that mileage. Replace new bolts and plastic and rubber pipes.

[@victorcastro5486]

Hi, I'm from Brazil and I got a 535i 1990 with 90875 miles and I'm doing some repairs in my car... unfortunately, here in my country the spare parts are difficult to find..... and sometimes the only way is "run" to an authorized, but, the prices..... oh my God.... Well, I'll keep working, it is a fantastic car.... She rides very well and very comfortable, considering her age... It's a great car ! I think would be nice to change some knowledge and some tips. Good luck with your car.

[@RobynTapps]

Victor Castro if it works use it man... BMW wants ridiculous ammounts for even the smallest of things.. $200 for an o2 sensor.. (Mustang ones work if you splice the connector and cost $40)

[@mainminevin]

Awesome video! Learned a lot from it about this engine.

[@cass71291]

Good to go sir. Interesting. You had my attention all the way through. Good job!

[@barney21477]

good video and nice looking ride. I wish my 90 5 speed was in this good of shape body wise. i'm planning on doing this job soon. loss of coolant and overheat. pretty sure my head will need milled. I read the manual but I like a good video to go along with it. you're a lifesaver. thanx

[@tgamber]

Ah you have the 5 speed, lucky man. I have the 4 speed auto version. Still goes pretty good though! I think I may have mentioned it in the video, but in the end it took me about three days (evenings) to finish this job. It's worth taking your time at it if you can. Good luck!

[@angelisone]

If the two camshaft's (24:35 on the right side) lobes are worn & causing a tick tick engine noises. Anyway to correct it or add or mod to lessen the noises beside replacing the camshaft? And camshaft used is way overpriced. Car has low resale value that I don't want to throw money into a 38 years old car (M7). Can the camshaft's lobe peak be welded while it still on the engine? Parts are so hard to find & once available the price is way up north.

[@loveofchem]

Good job, you had some fun. Feels good to make successful repairs.

[@homerfj1100]

Thank you so much for the time and effort Excellent.

[@UBBERTANKER]

always get the head surfaced and pressure checked alot of work to have to do it over again because of a unseen crack and it usually only cost about 50 bucks for the machine shop to do it

[@gregh7457]

"always" ?? i thought the only time you need resurface is if its warped or has erosion/pitting? I have no doubt this head gasket started leaking not long after because of all that erosion around the water ports. To repair that would require grinding out the eroded aluminum and tig welding, then resurface.

[@heinz490]

the engine block use to crack NeXT to the oil pressure hole

[@masscomnet]

Nice job and nice detail. I would have taken the opportunity to have the head surfaced and also have had some work done to the valves. Anyway, great job!

[@sagecreekwitt3301]

Thanks For Posting This. It's very informative. I'm amazed at how many trolls who've never made a video, are quick to post negative comments. We can all share advice, but to be an ass about it, demonstrates the troglodyte mentality of some full time mechanics. Their boss keeps them away from people for a reason. Lol.. I said some.. not most.

[@RobynTapps]

Sagecreek Witt just because you have never posted a video to youtube doesnt mean you dont know what your talking about. Calling people trolls for thier opinions is rather ignorant.

[@davedunn5781]

on your head cylinder number 2 has a pit going to your combustion sealing ring thats why that cylinder is cleaner, I bet it has been using coolant with a sweet smell

[@RobynTapps]

Honestly great video, i would have gotten that pitting filled on cyl 1 to avoid future gasket issues. Hope shes still running strong for ya man ;)

[@brettlincoln1963]

the m30 engine is a work of art and its good to see although a head job... from your best girlfriend to a bmw takes some work... hopefully the girlfriend will help the the m30 too lol no its good to see that they are so well made that they dont need the full gasket set to get you on the road

[@boghybb]

I know this is an old video but I have a question: I did the same for my M30 6 years ago and I can't remember if I torqued the bolts after running the engine at normal temps. I know that Bentley states that they have to be torqued at a specific angle after getting the engine into temperature. Did you do that or you just followed the torque specs from the head gasket pack? Thanks

[@Nightfly1957]

Very good job. Me, i am driving BMW since 1985: BMW 320/4, BMW 3181is, BMW 328i, BMW 528i, BMW 116i, BMW 125i with complete m-pak and m -erformance pak (not 218 PS, but 240 PS, and since December m140i. Last car is my favorite, the 125i was not good. As is ordered the car it had six cylinders, when i got it: 4 ylinder turbo. This car needs nearly the same fuel as the m140i. But: IfYou are drviving 130 km/h the m140 i needs about 6,5 l fuel

[@Johans60]

Different materials of head and block will allways give headgasket problems over 250000 km +But the pitting issue is likley caused by bad coolant.It will leak in no-time because you did not repair the pitting issue

[@alexkang5589]

Hello. Do you need any special tools to take your E24 engine rebuilt?

[@RivieraByBuick]

u have to oil the bolts before putting them. especially head bolts.

[@ITTV88]

is there not a drain off for the coolant on the bottom of the rad?

[@eddyLF]

Hi any idea what should be the compression for this engine with a" piano" pistons ty

[@Rockelement]

stupid question, but to turn the engine. Do you do that with the big bolt on the fan? I am planning to do a valve adjust, and im pretty new to working on cars.

[@phoenix_plays_3515]

you could do that if your belt is tight enough, if it isnt, you can turn the big balancer nut on the bottom. If you are only adjusting valves, even if your belt isnt tight enough, hold it tight with your hands, it will be good enough to slightly rotate the engine to get the camshaft lobes where you need them to be

[@nicolasfernandez7319]

hola me podrias ayudar con la puesta a punto de la cadena ? gracias

[@zakeh2833]

id like to add that a magnetic drain plug is always good when pulling anything engine related apart by the way how is she running now? i'm doing a full rebuild of my engine...i blew the bottom end on it a couple months ago. and yes your right you need to be patient with it and yourself

[@tgamber]

Yes, magnetic drain plugs and patience are always good things to have. Engine runs great, same as always! How did you blow the bottom end on yours? The bottom end is supposed to be really strong on these engines.

[@zakeh2833]

i got a1990 niissan 300zx and main rod bearing just had enough and said seeya soo. ive stripped my engine down to a bare block and am trying to find a job soon so i can keep it and start back on the build again. ivev been jobless since october last year...

[@tgamber]

Oh it's a engine from a nissan 300zx. I thought you were talking about another BMW M30 (which would have made sense because the video is about the M30 lol). The bottom end of the BMW M30 is built like a brick shit house, you pretty much can't wreck them...

[@TheGhostrose]

what is the ringing at the first start? I have the same noises now, is it chain need to change or what?

[@heinz490]

im a BMW mec and have never changed a chain in my history but worn Down rocker arms and cams yes the head gasket last for 200.000 km then it blows bet cyl 5 and 6

[@heinz490]

the m30 dont need rebuild but new camshaft and rockerarms

[@-ScroogeMcDuck]

Встал вопрос о покупке Е34 с двигателем 3.5i хозяин говорит что двигло ставили с 7ки е32, я еще машину не видел это еще предстоит. Ребята подскажите, помогите с информацией как не лохануться и не купить машину с М30В34(35) с двигателем М30В30 как различить эти 2 двигателя? они одинаковые на инжекторе если и написано 3.5 не факт что столбик 3.5 так развели одного моего знакомого ? спасибо

[@adamsdays8634]

Hey I see it's been awhile since you uploaded anything on your E34. I was just wondering if you still owe on the car and how's it running. I currently have a 1990 535i with 280k miles. It currently runs amazing but I plan to do this job in the future. I feel you did great work explaining how this job is completed. Only thing I would recommend now after seeing the footage is a lifter adjustment. Thanks for the great info!

[@leafaRPD]

Can someone measure the length of a BMW straight 6 engine block and write back to me? Or the full engine length with the front pulley, doesn't matter. Can also be the M52 engine. I was wondering how it compares to the Chey 250 inline six.

[@TurbineResearch]

your a mechanical engineer are you not? I lived in Calgary for a few years and noticed all the engineers have those pinky rings. just funny things I notice . awesome video thank you

[@tgamber]

Electrical engineer that is very mechanically inclined... I did have a pinky ring at one time, but I lost it out motorcycling haha.

[@charlesfiasco1626]

I'm currently replacing a head gasket for the same engine.. How do you take the nuts off the bottom end of the intake manifold? It's a little tricky as you stated..

[@tgamber]

When removing the head I took the head and the intake off as a single unit (had a friend help me). When putting things back together I did each one individually to make it easier to place the head(lighter). Putting those bottom nuts back on for the intake was very very tough. I used extensions, flexible joints, and spanners and still had a very tough time. Those things are in a very tight spot so no matter what you do it will be very tricky. Good luck!

[@junieserrano3990]

You have to rip apart the block and release your piston rings

[@markusschneider3908]

its not T/O it stands for Oberer Totpunkt = top dead center. Nice Video

[@woutergrootwassink6705]

Well at least the m30 block must be way better than the m20....for 2 years ago i have done my cilinder head together with my garage owner...now again oil pooring into my cooling system again and again....im really getting frustrated because only after 2 years you ll just have to get it of.....again!!! And there were more options about what went broke...the head that got cracked....the gasket doesnt tighten anymore... or a cilinder spring just broke....no fun after only 2 years and no big amount of kilometers....

[@RABERTRON]

I thought you were suppose to replace the HEAD BOLTS when you take them out.

[@tgamber]

If you had actually watched the video you would see that I replaced the "HEAD BOLTS". Emphasis on the capital letters there! People wouldn't be able to understand without the capitals!

[@RABERTRON]

Yes They did look new. I did not replace mine , and its still running strong.

[@ramirobeaz306]

Bobby Raber how much torque did u use on the head bolt pls

[@RobynTapps]

Bobby Raber big yes. 100% replace the head studs/bolts.. The OEM bolts are TTY (Torque to Yield) and stretch when torqued down. They are a 1 time use item. ARP studs can be reused.

[@Edward.1688]

Hi, very informative video, just wondering what product did you use to clean the cylinders ?

[@tgamber]

Transmission fluid. It dissolves carbon deposits like nothing.

[@Thom4zz]

[@BMWhips]

That's far from a rebuild Just a head gasket replacement. Could do that on lunch hour. Good job and good vid! enjoy your car it's a good one.

[@DeBaRe]

Actually the M60 V8's are smaller that the M30. And lighter ... anyway, nice video! :)

[@luketanner7638]

Defintely something that shouldn't be undertaken without know-how and proper tools. "Looks pretty good considering" visually is probably the worst measurement you can make, as well as a cheap ruler for checking the surface for warping. Engine don't run using clearances/tolerances that can be seen by the naked eye. The fact that it runs is luck all by itself.

[@johnbean2596]

What, do you think that every single head warps and requires machining? These things are renounced for running 500,000+km I'm sure it's still going today

[@davidmendez6483]

The video is good except you don't show taking out the parts and that's what annoying me so really didn't learn much.

[@Freemangelatala]

throw the fucking gum out. Jesus Christ man.

[@Troymatti]

ahahaha I was thinking the same ,

[@StBoychev]

This is gasket change not a rebuild.Sorry but it is stupid to take of the head without simple check of the valve seats. I am sure the valve guides are finished and for the valve seals there is no need to comment. Head grind is compulsery. Amateur work!

[@mosesmakiwa5519]

nice video i only ud stop making that irritating sound with your mouth

[@rv10pro]

Shaky video made this difficult to watch and learn.
