is it normal for the oil temp to go slightly above 120degrees? Mine goes to maybe 123 (slighly past the middle) or so when im in slow traffic or just crusing around town for a while and starting/stopping at lights etc. if i go on the freeway for even just 5-10 mins it starts dropping to 110-120

its an n54 335i

[7smurfs]

On hot days or lots of start/stopping the car will heat soak very quickly and go above normal range.

It should drop back down when the car is moving again however. Our cars like any other turbocharged vehicle runs very hot!

[/335]

yeah thats what happens. just wasnt sure if it was meant to pass the centre lol

[Brule]

I live in Darwin where its 30+ everday and around town oil temps sit on average 105.

At the track I cant continually wot. After 2 laps I have to drive moderately or it will go over 120.

I have the bms thermostat mod.

It also makes a difference if you are driving in manual mode (which I'm personally in 99% of the time) versus standard auto mode.

[MJ80.]

Iv noticed that, manual mode makes a huge difference, runs noticeably hotter.

[/335]

Yeah I/ve noticed that as well

[Fuji]

I noticed this just the other day too! I started to freak out a bit when I slowly rose from 110 --> 120 whilst stuck in traffic... Glad to know this is normal

[T1M]

Yeah the N54 has a high operating temp. It's normal.

What are some
Mods to combat the high engine temp
Heats ?? Which lead me to believe is the main cause for those pesky bloody gaskets to always start leaking

One of the cheapest mod I found was a side effect from installing the BMS cowl fitlers, after removing all that plastic cover onto top of the engine and letting the heat escape more easily I've seen an reduction of the oil temperature about 5-10 deg on average.

Used to sit around 110-115, now it usually sits around 100 and only reaching to about 115 after I've being crawling in 40+deg C traffic with A/C on max.

BMS oil cooler valve.

Yes I was gonna pull the plug

What kind of temp drop would we see with this?

Radiator that is found on the BMW 1M, 335is and cars that have the PPK2 upgrade:

Good idea if you ever track your car or have a tuned car that runs hot, I'm seriously thinking of retrofitting this.

Theres some oil coolers on the market also, but there were a lot of complaints about fitment and having to modify and cut stuff to get it all fitted.

Theres also some aftermarket radiators but there's no data on them and I don't think they fit automatic cars.

BMS thermostat would do nothing to decrease temperatures in the OP's scenario. It will just take longer for the car to heat up.

I never seen that before .... So that kit isn't a plug and play straight forward install ?

The ECS kit I linked will bolt right in and fit properly. The only extra thing you need is a plastic air duct for your bumper. There's a bunch of different 335i bumpers and each of them has a PPK duct that you can get to direct air flow to the new radiator.

[EB89]

Whats the BMS valve do then? they advertise...

"This simple engine oil cooler valve increases flow to your fender mounted engine oil/air heat exchanger resulting in lower engine oil temperatures and more consistent performance during heavy throttle"

Is it not for when idling in traffic but for heavy driving?

The external oil cooler in these cars have a thermostat (located in the oil filter housing) that opens when the oil reaches around 120 degrees. When the oil is below this temperature oil does not flow to the oil cooler.

The BMS thermostat just directs flow to the oil cooler 100% of the time. It slows down the rate at which the car will heat up. On a hot day driving around in traffic the oil will already be up to temperature and the stock thermostat would already be open. Its certainly useful in situations where the car is not under constant high load with low airflow.

The downside to the BMS thermostat is longer warmup times. There's an AD engineering thermostat which actually opens at a lower temperature which is best of both worlds, although for some reason he doesn't spec the temperature (I would guess it should be somewhere around 90-110 degrees).

[Jeff@TopGearSolutions]

The downside to the BMS is it's a thermostat delete but it's only a downside for cold climates in sub zero temps often, IMO. AD engineering as mentioned above does have a thermostat.

I'm typically used to Farenheight here in the states so if you see yourself exceeding 260F you should consider a factory oil cooler retrofit or oil cooler upgrade depending.

The stock thermostat starts to open around 238F

Coincidentally, we might be able to get our hands on an AD engineering thermostat in Aus here:

Ima call you Beamer yoda from
Now on ..... I'll def be looking into this extra kit
