The whole experience has been real humbling, I wasnt nearly afraid enough of water before. xD Ill avoid it like the plague in the future, an never forget that damn cap. Hopefully the insurance does a thorough investigation tho and pulls me through. There were like 4-5 other cars that had the exact same problem at that puddle that night, it was kinda a joke, half of us had pushed our cars out the water in costumes cuz it was the saturday before halloween, Im pretty convinced that the stock intake wouldnt have survived it. Hope insurance sees it that way |

If water was above the grill, factory intakes would have eaten it too. |

the issue with going back to a magnesium cover from the plastic cover is that the PCV system is completely different. It's way easier to just put the plastic cover on the longblock. |

that's just how water and engines works.
There's nothing that would have stopped that, throttle blade closed or not. I have plenty of experience with hydrolocked motors. like pulling plugs on the side of the trail and shooting 20 foot geysers of water from engines and then driving them back home experience. |

In July this year I hit a lake across the road, again at night. I hit it at 60MPH in my E90. Again the car hydroplaned across the water for about 4 seconds. Again no water in the engine. Again, the water was so deep it stopped the car. Both my cars have stock airboxes and air intakes. |

Yeah the insurance is its whole own issue, but given the nature of the road and having gone down into the water it seems like they will cover the damages at least partially.
But I finally got some word from the mechanic and they got the engine running. It was at least able to rev pretty healthily and shoot a gallon of water out the exhaust. They said it had two cylinder misfires shortly after though when they tried to drive it. I think I will go to the shop tomorrow so I can talk to the techs and get a really clear idea of what is known and what still needs to be looked at. Overall though its potentially good news, the 3 stage mani conversion sounds alot cheaper after having engine swap price tags in my head for a few weeks Those of you who have had similar problems, if it gets running again are there any long term worries I should have about water having gone throughout the exhaust system, or that it has flooded the intake manifold etc.? DISA valves maybe or a compresion problem? UPDATE: I went to the shop today and talked to the guy who worked on my car and picked her up, drove her home. Sounds like they flushed the oil and cleaned the housing and changed the oil filter but thats about it other than new spark plugs. They drove it around and had a couple cylinder misfires but it worked again on restart, I can't remember the codes but he said the ignition coils were his best bet. Everything seems fine driving so far, engine seems to run and sound as strong as ever. I might've just gotten that lucky. I'll have to keep an eye on her and any codes for sure but I seem to have avoided the worst of the probable damage. Headlights are a bit foggy and I'll take her for a real drive tomorrow and make sure the valvetronic and everything high rev range works well, do a thorough cleaning... Fingers crossed though and she's alive! Hopefully now the real work is just the intake mani swap! Last edited by Jonas.Steffen; 11-16-2018 at 04:33 AM.. |

Just curious what is the basis of your information/conviction?
I posted on this earlier on this thread there are 3 types of oil pan on an E90 N52, and even gave the part numbers. But maybe a visual presentation better works :P |

No they didn't, we thought that if the engine is running smooth and the idrive doesn't detect anything then the compression would be fine. Is that not the case? I can definitely go back to my mechanic and berate him for the test lol. He seemed confident that without any codes thrown or stored it is most likely fine unless theres some electrical damage that emerges after a little mileage. I like this guy for sure but maybe I should go to a serious bmw tech for this car...

Ya, I see the same thing.that rwd pan is showing a dipstick, which isn't available. They don't list a manual pan, there no such thing. The two pans are rwd, or xi. There are other engines which may list, like n51, and n53. I've looked into this tremendously, I have a 335 pan that I planned to use on my n54 going in an e60. The 335 ps pumps are smaller,and different mounting bosses. It's different on a pan that's made for a 5 series car. I've found over the past year while digging for answers on what compatible between all these engines. The 3 series are more common for parts than the 5 series. Real oem has always listed different part numbers for the same parts that has no physical differences.

You can even see the steel pan in this oil pan gasket DIY: https://www.e90post.com/forums/showthread.php?t=1180020 Might just be a cost cutting move. E60 uses the "automatic" pan regardless of transmission type. Last edited by Terraphantm; 11-17-2018 at 09:07 AM.. |

Same reason why all AWD oil pans are aluminum casting too, regardless of transmission type: the front differential bolts on to it, and the pedestal that passenger half axle goes into. You cannot bolt onto a steel pan without leak issues plus steel pan structurally won't be strong enough to support the front drive components like that. |

The steel pan manual RWD's use have a tube welded to the pan (if they are for magnesium valve cover n52 engines), aluminum ones (auto or all XIs) have a hole that a tube or plug goes into depending on valve cover version. Quote:
