M54 valve cover

M54 valve cover - 04/16/20 07:52 PM

At 116K miles, my BMW needed another valve cover gasket job. The first one was done at 52K miles.

After replacing the gasket, while the shop was putting the valve cover back on, it cracked, so they gave me a new one. Here is the old one. This is what short tripping during winter months up north looks like.

Ouch! I am assuming that based upon this (during the winter months), you will either shorten your OCI or take some longer drives?

Does a lot of moisture!
if I was doing annual oil changes, i would do it in the middle of winter after a long nice run.

Have you replace the PCV system???

I do try to take longer drives on weekends, but I won't go out of my way and just waste fuel for no reason - that's what I have the SRT for. smile

This BMW is my winter beater, and I don't drive much in general. I put on about 4K miles per year on it and change the oil once a year in early Spring.

They sure don’t make valve covers like they used to.

Believe it or not, these are the "better" ones. Newer ones list for 550 and have an integral PCV.

AND they get hard/brittle with age and heat.
Never had that problem with alum valve covers on the old ones.

I have heard that the plastic parts on BMW's go belly up as they age.

Not just BMW, but any car with plastic engine/cooling components.
Just ask Scotty Kilmer
LOL

IDK the plastic intake manifold on my old BMW is the one plastic thing that hasn't failed yet. And my ECHO is doing well with its plastic intake and dipstick.

I think it must have to do with the type of plastic being used.

Pete, driving a BMW 4K miles per year as a winter beater... I’m never gonna talk to you again!

But seriously, based on the car’s usage, I would have expected worse condensation.

Naw,...More like $200-$300 for OEM and $450 for Genuine BMW. I just had the gasket/cover replaced on my 435i. My cover was replaced out of an abundance of caution due to the intergrated pcv design and I plan on keeping my vehicle for awhile since I won't "give it away" at some ridiculously low price on the used market.

I've had good luck with the ebay valve covers (whole kit is $150) on the M52 and M54 engines. For the N series engines like my N51 you want to use the OEM cover because the PCV valve is integrated into the cover after 2006. Even then, you can get OEM covers for $500 on FCP Euro which comes with a lifetime warranty. You can find other sellers for cheaper. Personally I lucked out and had mine replaced by the dealer under the SULEV warranty.

I almost purchased one via AMAZON on an alleged Mahle cover, but I wasn't confident it was what they said it was and I still to buy TTY bolts, vent pipe and screws/seal for the valvetronic motor. In the end I went with the kit sold by FCP Euro.

Looks like every m54 I've opened up. No matter what you do there will be mayonnaise. It's just a cold spot above the intake cam shield.

Maybe I've been lucky but I've never had one crack on my cars, and my n54 only runs about 10 minutes per trip in the winter - just enough to get it really wet.

Same here WRT cracks- I've only replaced gaskets.

From my experience, the N52/N54 cars are more likely to crack the cover, while on M52/M54 it is more likely to warp. A warped cover can be fixed by applying some ultra gray RTV all around the sealing surface of the new gasket.

Why is only one side and the end all "cheesy"?

Probably because there is less air circulation in that area.

And that big mess is why I love my M50TU in my 1994 325is coupe. Metal valve cover (magnesium I think) and the simplest crankcase ventilation system. I have never seen any of that. I live in Boise area with variable winters in terms of temperature. Granted the M50tu does not have the performance of the M54 but I don't have to deal with CCV issues or oil consumption. I think BMW messed up that motor and of course, it went into a lot of models for quite a run.
