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.

There is only one way to remove and reinstall the camshafts safely without the special tool, and this that way.

Hey man, super thankful for all your videos! Been watching for a couple years now. Just got a 323i with an m54 for free that's got some lifter noise and thanks to you I'll be able to tackle the job with confidence!
sister had a bmw…what a pos that car was
Awesome video ,thanks!
Dont clean lifters just replace them
E is for Einlassseite (intake side) and A for Auslassseite (outlet side). Thats why there is E and A.
Anyone know how much wear on the cam bearings is acceptable? I have noticeable wear marks on just the exhaust cam and ledge, can barely feel some with my finger. Can't find any used ones that are in better shape, they all seem to have the same wear.
So I'm looking at a 2001 325 and the owner said he did the head gasket but broke a camshaft when putting it back on. Would the camshafts from my 2000 328i fit? And is there anything else I should be weary of or look for in the 2001?
Another good bit of info well explained.
you are a life saver
I'm a subscriber…does this same method apply for aftermarket camshafts?
Will this method of cam removal (only) work on a S54?
12:10 lol perhaps i misunderstand but absolutely no chance i am reinstalling everything after the lifters in less than half an hour…the cams, timing parts, cover, vanos, intake, throttle, disa, wirrimg harness, oil dip stick tube, connectors, air box and pipes, belts, fans, firewall….
You know I've been watching alot of your videos since I got my e46 330i and your videos are probably the most helpful videos on YouTube for e46 stuff.
Does the M54 Engine not take any Rod Bearings?
Can you do a rough sketch and dimensions on the tool you made for removing the “keepers” and springs please? I really enjoy your videos. They have helped me tremendously!!!
Do I put the auflass (exhaust) camshaft back on in the same position as the einlass (intake)? With cam lobe 2 slightly to the left and lobe 4 to the right of top dead center??
Good guess. Exhaust is auspuff in German and einlass is intake
Please I had mixed the lifters by mistake I’m worry to put my engine back what you think I can do ? About the lifters
Hey, I want to replace my intake camshaft on tub28, basically I can just remove vanos and vanos gears and leave exhaust cam untouched?
Dear 50s kid there is a question i wanna ask you i own a 330ci e46 and i am facing some problems with misfires w fuel cutoffs i replaced all the essential (sparks, coils, injectors) components but still runs rough when cold and misfires my mechanic insists that the problem are the lifters of the car btw no6 cyl has a within limits low compression rate. Can lifters associate with the missfires and roughness!!! Thanks in advance!!!
