BMW E46 Replace Valve Stem Seals (head in car) #m54rebuild 10

520 ratings | 43575 views
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 head 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.

You also need some basic metal working tools, such as a drill and drill bits, a cut off wheel, maybe some files to smooth down the burrs. Nothing major.

blow urmind (8 days ago)
how do you hold the tension for the cam chain...the tensiooer will flick back and be virtually impossible to reset...wont it??? then also the valve timing will have to be set up again...maybe??

You can remove the seals off easily with a torx nut. Just pick one that fits the metal part and tap it in with a hammer. Then twist it right off.

Instead using a nylon rope in order to keep the valve closed - I used zip tie :)

Dear 50skid: I got chain noise and chain timing problem at my E46 316i with N42B18A engine. It doesn't react to anything when I take valvetronic or solenoid cable off. Only it makes lots of noise like it's a bad diesel engine. When I start engine I hear chain clearly laud and clear noising and after 2 min engine shaking a lot and go out. What is the problem and how to fix please help.
William Harrison (2 months ago)
I had what sounds like the same issue on my E53 X5 with M54 engine. Not sure if this will work for the N42B18A. I rebuilt the vanos, still had the same noise, then reset the timing and finally the noise went away.

homemade spring compressor tool improvement idea: instead of using the vertical center piece of metal, drill and tap the center of the top metal piece and use a bolt to compress the bottom piece.
TheAkNas (1 year ago)
Hey do you know anything about n52 engine? I want to replace the valve stem seals, and so far from all the info available online I would be able to remove exhaust camshaft to get access to exhaust valve seals, but the intake side is tricky because there's a lot of retaining springs, plates and the camshaft tray is cast with the head, in the repair manual a lot of special tools are used to remove the intake side so I'm confused...

William Burdine (1 year ago)
Actually someone did do this video, just before yours came out. Goes to show you that there are multiple ways to think out of the box and be creative. However in both you video and the other, I am surprised neither use tape or paper shop towels to block all portal access in to the engine.
50sKid (1 year ago)
There are just the 5 oil drain ports and if you're careful you should be fine. If particles do drop in they'll hit the oil filter before the bearings but of course you don't want them to go through the oil pump in the first place.
solo1racing (1 year ago)
Can you do this job without the fan is and timing removed,just the valve cover?
battlefinder (1 year ago)
Ask yourself this. "How do you access the valve springs?".. They are under the camshafts, which are attached to timing gears.

How did you make the guide on that tool that you made .. and how did you put the Rope on

hi 50skid, can someone use this tool for that job? https://www.youtube.com/watch?v=pM9KXEw_Wd8
Gilbert Irungu (1 year ago)
ok cool. thanks.
50sKid (1 year ago)
Gilbert Irungu you won’t be able to get the arms down in to every spring because they sit down in a little well.

Hi mate I've got same bmw and i found the spark plugs head swimming in oil the compression is good on each cylinder can be the seal valves stem the problem?

Better go get a patent before someone else makes a fortune off your idea just saying great work keep em coming
sambking (1 year ago)
Great home-made tool to get the keepers on....and off, really. I would plug the oil return holes to be safe. Pretty cavalier with those keepers around that engine. You drop one of those keepers in a return hole and you have, in a split second, created all sorts of trouble for yourself. Love the videos! Be careful and keep up the great work!!!
bimmer325cic lee (1 year ago)
so creative. That home made spring compress. u are a genius.

Could you post the dimensions of the tool sections? I think this is fantastic!
David Rios (1 year ago)
i like the improve tool nice idea i just bought a e 46 and its consuming oil and smokes blue, the guy that sells me the car had the valve stem seals in the trunk but he wasnt sure that was the issue, i was thinking in changin the pcv valve first then if the car remain with the issue then replace them but the car has 279,xxx miles so i think i'll have to replace them anyways
David Rios (1 year ago)
50sKid i saw the video im goin to try the valve in the hose that goes to the oil level stick thanks youre videos are very helpfull
50sKid (1 year ago)
i have a video about the oil consumption
YourBimmerTech (1 year ago)
Probably wouldn't use vice grips to pull the seal.. could bend the stem. A little sketchy.

I'll say....WOW!

Love the out-of-box thinking on this tool. Definitely adaptable to other applications and can be made on demand. Thanks for sharing!
50sKid (1 year ago)
2000shellback (1 year ago)
thank you VERY much. I'm going through the same process. Not sure if discussed before, but are we putting unnecessary stress on the studs when using them for this type of application? In other words, are we stress/pulling them out of the aluminum head? I wish I could make a tool like this. Thanks again!
50sKid (1 year ago)
Yes I would have to say you are putting unnecessary stress on the bolts but I do believe it should be fine. You can make a tool like this with a hacksaw and some drill bits.

I've got the same engine. Where did you get the valve stem seals? Do you have a part number and/or the link? Thanks so much and great job man!!

Thank You so much for your videos. I really liked your valve spring compression tool and will use your idea when i do my son's car this weekend.

Nice piece of tool u made there
Rob PhoboS (2 years ago)
Nice use of the spare parts to compress the springs for the retainers :)
Mc Terb (2 years ago)
I think it will work with this tool on my M52B25 as well. Very clever to use the bolts for the camshaft to actually push it down. Nice job! Other tools always require a hand to kinda push the spring down. Now i only need to find out how to get cylinder timing correct afterwards.
50sKid (2 years ago)
No you can't, you need the timing tools.
Mc Terb (2 years ago)
Already watched the removal one :) but now i am wondering if i can remove the camshaft without touching the timing by just loosening those 3 nuts that attach each camshaft to its chain wheel. Oh it's too late here in Germany for those things :D
50sKid (2 years ago)
I have a timing video, just search my page.
Daniyal S. (2 years ago)
hmm there are alot of 350zs and g35s for sale for like 2 grand cheaper because of this and it doesnt seem to hard but my dad is telling its a real pain. this doesnt seem to hard though.
Rob PhoboS (2 years ago)
JWT make a tool for our engine: https://www.z1motorsports.com/engine-parts/jwt/jwt-valve-spring-compressor-p-7040.html Video on youtube showing how to use it, as well as a PDF. http://www.jimwolftechnology.com/wolfpdf/VQ_SPRING_REMOVER_INST.pdf Also don't forget the timing chain removal on our engine is a bit of a pain, once again, plenty of vids showing how to remove/install.
50sKid (2 years ago)
Yep, exactly. Everything else is straightforward.
Daniyal S. (2 years ago)
+50sKid so you're saying finding a tool to compress the springs is the hardest part?
50sKid (2 years ago)
It really isn't hard, but every car is going to be different. There are different tools available for compressing the valve retainers. Harbor Freight carries a cheapo one that clamps over the sides of the spring and screws down. Search for "valve spring compressor tool kit" -- another style of tool comes up. Make sure you have a good strategy for compressing the springs before you take them apart. I would say, if you can use the tool to compress the spring and get the keepers out, then you can use it to get them back in. With the exception of the tool I used to remove the retainers in this video.

billy mitchell (2 years ago)
another good video .a good tip when replacing the valve collets is to have a thin flatbladed screwdriver and grease small amount of grease on the inside of collet and on flat blade of screwdriver so collets sticks to screwdriver and then just place collet on valve stem and it will stay there ...magic .....never lost a collet doing it this way
Amazing, love the diy compressor 10/10. Guessing this method would be the same on m50 & m52?
50sKid (2 years ago)
Yeah exactly the same.
Billy Johnson (2 years ago)
Maybe one day you can buy a e39 M5 and do a whole new series to help me learn wrenching on it? (Kidding) Great job.

Some day lol
Gimp Master (2 years ago)
Possibly cut and Glue 3 x uprights for your home valve spring tool. So glad you are doing this work and giving everyone the benefit of your serious apt and altruism. Big fan....
Gimp Master (2 years ago)
Thanks man! Proper.. Are you going to vid the process of cleaning the head, and I'm sure you're contemplating a head skim and valve re-con, re-bore? Covering your visit to the machine shop would be great. Having the correct tools for the job is the way to go!
50sKid (2 years ago)
Yeah I'm doing all that. I will see if I can do some kind of videoing at the machine shop. I'm contemplating going to a shop that is an hour away because the owner actually does youtube videos himself (fiatnutz channel) and looks to be a very competent shop but I'm also thinking he's probably more expensive. I need to do some shopping and I really need to finish up filming all the videos on the parts that I need to film before they go to the machine shop. I am nearly done.
Peter Heisar (2 years ago)
Good job mate, clear vid and well explained. I am doing at the mmt vacum leak problem according to your vid smoke mashine, works nicely! Have you encountered an error code (Peak) 2777 DME: selftest: AD:converter by any chance?
Peter Heisar (2 years ago)
+50sKid Shall order one today, as grandpa said:' you ain't that rich to buy cheap shit things" :) Thanks and enjoy the break!
50sKid (2 years ago)
Yeah that is definitely your problem. Never use an eBay MAF--they use a cheap resistor and not expensive platinum wire. Only use a Siemens unit.
Peter Heisar (2 years ago)
50sKid This will definitelly get me commited to mental institution. After about 100km the light comes on and now it gives me code 2777,2882,2883 did a smoke test again and there is no leak! that i am sure of:)) Could it be an inferiror MAF that I got form ebay? Ts the only thing I can think of. Any thoughts? Thnx.
50sKid (2 years ago)
I've never seen that error but it seems like it might be a problem with your reader connecting to the computer.
Jose Diaz (2 years ago)
Awesome job. The 50's Kid deliver once again. Thanks!
Danimal780 (2 years ago)
Thanks for the vid! Perhaps 0.5" square tubing would be safer for the vertical piece of custom compressor tool. Also maybe it's possible to check valve guide clearance if you drop the piston a little bit?
50sKid (2 years ago)
Yeah I like your idea about the square tubing. If you have the means to cut it squarely, ya know? I don't think you'll be able to check valve guide clearance that way really because the area that sticks up is the "wear" area, except for just a 1/4" below the keeper grooves. Coming up in a video I will show how I do check the clearance from the other side once the head is out.
swamp (2 years ago)
your comprehension of what the home diy'er goes thru and needs to know is top notch....great video and tips ....also consider .....white dots from felt tip on top of valve collets to show tops....very good in low light situations for the diy folks.....touch of grease on inside of collets to help keep them in their positions on the valve while you uncompress the spring .....the essential zip lock bag over the valves to retain flying collets and enable y'all to see thru the baggy to work .....final step is to keep baggy over springs after completion and pop the valve top with 2 lb hammer to ensure all is seated good....looking forward to head removal....best wishes .....work safe
50sKid (2 years ago)
Thanks much. Yeah there are always a few things I want to add to these videos after I complete them. Like using grease to retain the keepers. But honestly the coating of oil that is on them is good enough to retain them I think that's why I didn't mention it. But I should have mentioned THAT.
Gerald R (2 years ago)
Hello. Your Tool is Great. To push The valve up, Use Compressed air. Is much better and comfortable.
50sKid (2 years ago)
Yep it's definitely a valid way to keep them up. The reason I chose to use the rope is because not everybody has an air compressor AND a compression tester with the hose that screws into the spark plug hole (which you'd have to take the valve core out of with a valve core removal tool) but everyone can buy a length of rope from the hardware store. I suppose I should have shown both.

nice idea with coming up with that tool. For my Honda engine street rays makes a very nice valve spring compressor tool. good work.
Dicer328 (2 years ago)
Most impressive.
bbogdanmircea (2 years ago)
How strong are the springs ? Are they strong enough to get the small keepers flying if your compressing tool will skip ? In this case you shouldn ' t use your fingers to put them in I think
50sKid (2 years ago)
Yes they are that strong
jefftc14 (2 years ago)
Awesome video man thanks! Curious though as to why you decided to replace these seals, was there a particular reason or any signs they could be worn?
50sKid (2 years ago)
Yeah exactly anything made out of rubber, just replace it. They're so cheap.
jefftc14 (2 years ago)
very true
Tool0GT92 (2 years ago)
jefftc14 you might as well replace all you can at this point
Dale Yurk (2 years ago)
Great video, and brilliant idea for the home made spring compressor! I am loving this series. Can't wait for the next one. Keep up the great work.
