Injector (44k, warranty)
Rear wheel bearings (current)

Replaced preventatively/for modding:
FBO modded
OFHG
VCG
Belt
Pads and Rotors

Maintenance:
Oil every 5k
Spark plugs every 60k
Coolant flush at 100k
Brake fluid every 75k
PS Fluid at 130k
ATF and Diff fluid every 80k
DIY Valve Cleaning at 80k, 130k and 190k

Work is 140 miles away, four days a week. But if I'm not doing that then I'm probably driving anyway

You need a Diesel. But good to know you are probably one of the few to put that many miles on a 335.. Write Bmw NA when you make it 300K..you might get a gift..

My drive to work is a very unfulfilling ten miles..... Barely enough to get warmed up

What did you do to clean your valves????

Wow. Refreshing to see. If you read these forums enough you would think the engine blows up just before 100K.

Lots of fear mongering surrounding BMW's. As with all things a proactive and knowledgable approach can solve/prevent alot of problems......hopefully.

I am 400 miles away from 100k and replacing my water pump and thermostat this weekend. I have been paranoid about failure since about 60k and everyone I talk to has had it fail way before 100k. Your 172k on the pump makes me think I am wasting my money. Anyway, it is a DIY and the cost is $450 total. I've wasted money on worse and I will feel better about taking long trips which are fantastic in the 335i.

[Miller335]

That is amazing.

Congrats.

I probably will buy a diesel next, but anything beats driving my old wrangler there. A whopping 15mpg out of a 2.5L 4-cyl hahaha

The electrics apparently get battered by the continuous heatup and cool down of the engine. Since mine is run more frequently and for longer and doesn't constantly start, stop, heat up, cool down, maybe that increased the life? Other high-mileage e90s seems to show similar trends but for now there's no telling. One thing is for sure, BMWs are not known for their cooling systems so a little preventative maintenance there could never hurt.

There is a DIY somewhere which I followed but basically I took the intake mani off, found which cylinders had valves closed and filled them up with carb cleaner, let sit, scrub off with gun brushes and wire brushes, suck out with shop-vac. Then just turn the crankshaft to move valves and close the other cylinders, repeat for them. It's very easy to do but it does take a few hours.

Good story! Nice to see a 335 hold up as well as yours has.

btw, any pics?

[lilez19]

Wow lol

That is awesome. Congrats!!! what performance mods do you have on the car. Trying to figure out what mods cause a lot of stress on the drivetrain and motor.

I'm pretty much FBO. Engine mods are as follows:

JB4
Raceland Downpipes
ER Intercooler
Injen DCI
ER Charge pipe
Forge Diverter Valves
Riss Racing OCC (I think they're out of business now)

[catcher22]

sir that is awesome

[srezzo]

Congratulations! That's a great accomplishment!

[_Sinister_]

Makes me proud

[napeHbNYC]

Congrats, man, sounds bit up, but you are right, just maintain the car and it will be fine

Must be a good work to drive 140 miles to work

[e90Mark]

Very refreshing to see this. Also 172k for original water pump? Must be a record.

[fun2drive]

There is no reason we should be replacing water pumps like we are but I think the conditions you have are the main reason. I don't drive short distances and never in salt or cold weather but I keep a new pump and tstat in my trunk.
I have the OFHG leak and the trans leak both which will be addressed soon.
I think your OCI of 5K is key to not getting an overwhelming build up of carbon on the intake valves.
I sold my M3 last year with 284K miles to a friend with everything running just fine to include every switch and control...
I do all my own work but was planning to have the valves done with the OFHG but thinking I might just do those myself now.
Congrats on the miles!!!!

[Blubaron79]

I have 112,000 on mine and still going strong!

But I just ordered a 435... :-(
