Default n54 hitting 100k miles - what to service - 10-31-2017, 08:16 PM

Hello,

I am getting close to the 100k miles mark on the car. I've had it now for 2 years now with nearly no issues.

Currently on the list of things to do (which i already have the parts for) are:
-Valve Cover Gasket
-Oil Filter Housing Gasket (with oil cooler plate gasket + new o-rings for oil lines)
-Sunroof Seal

I recently changed both upper rubber seals on the front and rear windshields as they were breaking apart.
Car gets regular oil changes and 94 Octane.
Plugs and coils are pretty new.
New vacuum lines.
Walnut Blasting.
RB PCV Valve.

Wondering If i need to or should change the following parts?
-Accessory Belt & Tensioner/Idler Pulley (I see kits for this everywhere)
-VANOS actuators

OR anything else that might be recommended to replace or look into?

Thanks for taking the time to read and help.
Its my first BMW and I've always taken good care of my cars.

Cheers,

I'd suggest keeping an eye on your water pump. Seems the plastic impeller housing likes to crack.

Would do the belt and tensioner as a precaution. I did mine before 90k after reading some of the stories. Especially do it if oil leaked on it from OFHG or elsewhere.

Water pump on watch...check
And yes the OFHG and valve cover have been sweating for some time so we gotta get the gunk cleaned up. I'll order the belt tensioner and pulley kit.
More suggestions and insights are welcome.

belts/ pulleys are a good idea.

You don't mention if you have an auto or manual? Assuming auto, would do the trans fluid flush and replace the pan. also a good time to do valve bodies upgrade, zip kit, etc. while you're in there.

if suspension/bushings are still original, would replace all rubber bushings and ball joints in the front and rear suspension. Also think about shocks/struts.

coolant expansion tank

alternator

water pump/t-stat

boost solenoids

I'm told the transfluid is not require but the differential fluid is?

yes its an automatic.

sorry but what is a zip kit?

will keep an eye on suspension. i know one of the tie rods will need to be replaced soon, will do both sides obviously.

why coolant expansion tank? are they known to crack/leak?

I would change out the PCV valve. Either OEM or RB. Its cheap and easy to install, and a bad PCV leads to pressure related issues (leaks, blowing smoke, etc.)

pan replacement is probably due, and fluid has to come with it.

yes, forgot differential fluid - would definitely do.

Sonex makes a maintenance/upgrade kit called the zip kit for 6hp19/20/21 trans - search. I don't have it but others have said it works well.

yes, just a matter of time for all n54 models. Mine fortunately just cracked last year - others have actually exploded.


Another thing, oil plan gasket and new oil pan bolts are probably due as well.

if you go for the oil pan you should consider engine mounts as well. 335is mounts would be an upgrade

Complete suspension overhaul using better than OEM parts. That's what I did and the car drives like new. I'm good for the next 50-80k miles

Imy suspension seems pretty good still but I'll keep an eye on it.
As far as the 335is motor mounts suggestion, don't think that will work as I have a 535i.
Trans pan has to be changed or just the gasket??
Oil pan also or just gasket?

I'm pretty sure both oil and trans pan are sweating a bit. Subframe must be dropped for both correct?

My bad I missed to see that you have 535i. You should change trans pan and only gasket for engine oil pan. I don't think you need to drop subframe for your trans pan but for 335i you need to drop subframe for engine oil pan not sure about 535i tho

Meyle HD suspension parts and ST coilovers. Everything is solid and tight. Bought the parts from Fcpeuro with lifetime warranty. I've tested them and they're true to their guarantee of lifetime warranty. In other words, when it comes time to replace my suspension, it will be for free except shipping back to them the worn parts.

535i sport auto owner here...trans pan/filter is easy access and it will come with the gasket installed. Oil pan gasket is a subframe drop for sure and it is recommended to replace the aluminum (blue) bolts...lots of work for a diy. I only changed mine because of leaks. Diff fluid is easy. Regular brake fluid flush/replace is recommended and might as well change out the steering fluid and coolant.

i'll definately look into the fluid flushes, thinking maybe i'll do that and the oil/trans pans at same time.

If you have 100K and suspension is all original, it's time.

yeah, 335is mounts don't think they will work on e60

trans pan and trans filter assy (Again strongly recommend zip kit, valve bodies - wish I had done that last year when I did my pan)

Just the oil pan gasket and bolts, not pan unless it's damaged. Also good time to look in bottom of pan when you remove it for debris/sludge/shavings/etc.

Hi, my 335i is approaching 100k miles too. With 530 european HP, I am considering changing the rod bearings. What do you think? I've read that many engines were destroyed due to the rod bearings failure...?

Also I might add the HPFP, if you have not changed it. Mine died abruptly at 90k km.

I got the ECS belt kit a couple years back and it has been working like a champ. Zero issues.
