Can you post a picture of the front of the car? I'd like to see exactly what BMW is/isn't doing to cool the car via frontal air cooling. All of a sudden I may have an example to explain the hole in my hood on the ehvoh. Edit:: Supposedly a good cylinder head can handle 240 degrees coolant temp before major damage. Oil temps are typically 50 degrees higher than coolant (depending on where the reading is taken from). Apparently BMW shuts the car off right before major damamge. That is a GOOD idea that I wish more OEM's did. However: 1. Shutting off a car cooking at 300 degrees 2. Getting to 300 in the first place. Owie, maybe too much NVH insulation? Design dictated by NVH? Or just bad cooling system design? _________________________ “ the only people that care about this aren't car people anyway. we don't consider EVs for anything other than point to point transportation like a bus or a plane. do you care how fast your plane can taxi down the runway? the dodge is a drag strip monster, and a hell of a good one at that.” -Rex B16, June 11 2024

At the same time, other stories are coming out about similar experiences. However, one 335i driver revealed that his owner's manual states that 340 degrees is withint he normal operating temperature of the engine's oil. Wow!

danl danl Post Master Supreme Registered: 07/14/00 Posts: 12783 Loc: Maryland USA	340 is much too high. I know they are relying on synthetic oils these days but that is still much too high. BMW is pushing things toof far. They have been having motor problems then they start pulling these stunts. They are also famous for voiding warrantys. A person in pittsburgh was denied warranty work when they scanned his ecu and saw that he did a lot of spirited driving. FWIW (because its all I really know) many Evo guys are seeing 210 oil temps on hot days when lapping their cars. Coolant gets slightly above normal and rests at about 200 degrees (tstat is 180 on the evo). _________________________ “ the only people that care about this aren't car people anyway. we don't consider EVs for anything other than point to point transportation like a bus or a plane. do you care how fast your plane can taxi down the runway? the dodge is a drag strip monster, and a hell of a good one at that.” -Rex B16, June 11 2024

MikeYOX MikeYOX Post Master Sr Registered: 07/03/00 Posts: 7607 Loc: West Boemfugk, Egypt	That's what I just don't get. If I look in the bumper of my friend's 325is (1987), not only does it have a giant oil cooler there, but it actually has its own dedicated opening in the bumper and is closed in with ducting so that it gets direct cool air. Now how does a company that took oil cooling that seriously for a meager 160HP engine back in the 80s allow such a thing to happen? I wonder if that 340 temp is the oil pan temps, or after the oil cooler? I mean, I've seen some road racers complain bitterly that their oil temps hit above 250. Now it's got me wonder what the average oil temps are in a 997 being driven hard. But then again, a Porsche turbo oil cooler is more of a radiator than a cooler B'GASS LOL. Either way, I hope the issues have been resolved. This is definitely one of the coolest cars BMW has made in a long time.

beerslurpy beerslurpy Post Master Supreme Registered: 05/04/02 Posts: 15480 Loc: Spring Hill, FL	What the fuck, seriously? Also, why wouldnt coolant temps rise as well if the oil is getting so hot? And wouldnt exposing the coolant to air cool off the engine? Or is the antifreeze and radiator just for decoration? This seems like evidence that BMW seriously fucked up. My car is probably not as euro-quiet as the average bmw, but when my temps go above 94C I start to get worried. Above 110C, my ecu cuts redline to 4000 rpm and doesnt let me into boost. This has only happened 2 times- 1) when my water pump belt snapped and 2) when I drove in full boost for about 20 minutes with the AC on. Turning off the AC dropped me immediately back down to 92 C. And I'm still running a completely stock cooling system with an intercooler in front. BMW fucked up.

During the summer months here, Evo/STI/turbo powered cars seem to have to pull off the track after 5-7 laps to cool off unless there have been some cooling mods done.

However I looked online and found that the oil cooler is tucked ahead of one of the front wheels since the intercooler is taking up space in the center. I can't comment on airflow to the cooler because the pics online suck.....but I will try to look at one at work. I also checked for any service bulletins related to oil temps and I found nothing.....

DPG23 DPG23 Post Master Sr Registered: 04/15/01 Posts: 4771 Loc: Los Angeles, CA	We did some investigating at work, and it seemed like the only 335s that got oil coolers had to be ordered with manual trans and sport package. Surprisingly it's a rare combo because I've only seen a handful with oil coolers. EDIT: In that article they show an automatic with an oil cooler, so my theory goes out the window.

si=yes si=yes Newbie Registered: 02/22/07 Posts: 51 Loc: Los Angeles	Since I will be getting a 335i in July I have been following this issue very closely. There was a batch of early US bound automatic equipped 335i's that were built without oil coolers. When run hard the oil temperatures could go to or above 300f. However, all manual transmission equipped cars had the oil coolers. Those cars had no issue. I was recently at a track day where one of the instructors was driving a 335i stick. He pounded the snot out of his car and never saw oil temps over 240. This guy even had an add-on module that raised boost about 2psi so he was making about 340hp. When asked he told me that he has never had an oil temperature issue. IMHO I think reports of this problem were greatly exaggerated because of the internet. In all I have counted about 15 cases of owners reporting high oil temperatures. From a purely statistical standpoint 15 out of thousands of cars sold is not a huge issue (although I would be really pissed if I was one of those 15). And FWIW it was not all e46's with engine issues...it was the first year of the e46 M3.

There's some other thread about the high pressure fuel pump going out on these too, maybe you should look into that. Like I said before, another year or two and these things are going to be awesome $\:\)$ _________________________ "On the street where there is no lap timer, feel is all that matters" - scootergeek "A bunch of nerdy douchebags chasing a ghost." -Ob1 on bitcoin

They recalled the motor and extended the engine warranty to 100k miles (from 48k), shit I almost wish that would happen to any car I buy, lol.
