Any update fella.

Look at my case. I was driving 20milla brake to cross and turned off did not want to turn on more seemed battery out of control. well the engine was very hard to turn with a wrench remove all spark plugs and run still a little hard turn turn testing oil change after loosen up chevere gave it a start like this and everything normal. when you plug the spark plugs and light it, it turns on by giving it, giving it about 30 seconds after giving it, it gets hard again. Bonda oil and fine probe has no oil canister and its oil was normal. The bathroom solenoids clean them. when it is hard I put everything down again I give it again and very slowly it comes loose. No fucking idea it can be. I watch the roar of cam and it's fine. It seems that a part is filled with oil and gradually blocks the engine.

granted I have a N54 and have actually only done 3 oil changes myself and the rest were dealer ones since I am basically low miles every year, what is priming? The sad part is I don't even give it any thought, maybe I should. I just make sure I replace the o-rings, I absorb up all the old oil in the OFHG, and our a little into it (measure out 6.5 qt. and that's all I pour in total), basically lube the cap and torque it back to whatever might be 18 ft. lbs. Sure hope I don't forget a step etc. I suppose I always viewed it as "just an oil change..."

Sounds like I will never let anyone but the dealer change the oil in my X5 with an N55. They break it, they bought it.

That seems to be the only piece common in all these instances.

I agree with this.

One of the possibilities of this failure is the oil filter cage gets pulled off with the
old filter and thrown out. Then a new filter is put in without the cage. Big problem. I read a post by someone on the x3 forum that did this very thing and had engine issues.

Here is a picture of the n55 oil filter cap. The cage has the green o-ring attached at the bottom. Without the cage, major problems. Thoughts?

OP, you are in Canada, how cold was it when the car was started? This seems to be a common failure on the N55 in below freezing temps. BMW does not know why it happens yet.

[TunafishE93]

What was the oil pressure after oil change, what did the oil temp get up too, was there any warning lights?

[ricx]

Never heard of this, an oil change could destroy your engine.

[TunafishE93]

Never heard a broken belt could destroy your engine either.. Till BMW..

[Tambohamilton]

I know it's not what you meant, but there are many many cars with timing belts, where a broken belt will cause your engine to eat itself instantly.

Also think about VW's TSI engine, where under tightening or over tightening the oil filter can cause total loss of oil pressure. Doesn't mean they're bad engines, but it does mean they're sensitive...which isn't great.

[TunafishE93]

I have had two cars timing belts broke on me, 92 4 cycle mustang going 80 mph on highway and a 95 accord going 35 in town. Both replaced belt without further issues. I have heard of valves getting bent on certain cars but never experienced this.

But thats off subject, its pretty good engineering to design a car to toast engine with a gasket change or belt failure. What they call it job security. Just make it last long enough then self destruct, genus!

Can you tell us how you did your change exactly. The steps you took. Are there any codes present ?

Did you run the car by any chance without oil at all even for just a crank because of a mistake ? And then put oil in after you realized ? Just asking ...

Lol... I remember that thread

Shush MMT, I brought up this possibility two years ago and was widely poo pooed. At the time I read something indicating that there were a bunch of failures during cold weather in the Chicago area. I suspect BMW will say or do nothing, and is hoping these cars will simply go away. In the DFW area I see fewer and fewer of them by the month.

Ohhh by your username I thought you were in Australia, which I was like how did he get a failure if it happens in cold. So when yours happen it was freezing weather to?

[yellowlotus]

just a defective engine

We had a bulletin from BMW to contact them when we get any N55 cars with seized engines in cold temps. Personally, I feel like it has something to do with our variable oil pumps. Something gets stuck in there and stops oil flow. Seems to happen much more in the X3 and X5.

[C4maro]

Question : is it necessary or recommended to crank engine on n54 after oil change to get oil flowing by removing coils or something similar to stop engine from starting?

[Tambohamilton]

I believe you can code a start delay in CAS...it makes sense to, if there are potentially going to be issues, I think.

[Ozzie335i]

Nah, I am not an Aussie, I am a Yankee transplant to Tejas. Like fatty, I changed out the rod bearings proactively. You may be on to something with the oil pump.

[TunafishE93]

Shouldn't there be a warning if the oil pressure is not there? All the stories I have heard is the engine just stops, with no warning. This tells me the oil is flowing... Or there is important information being left out..

I am N54 and I still did it for peace of mind, just take 10-20 mins more to the job. I did it by unplugging fuel injectors. I think you can just remove the ignition harness to but I rather do the fuel injector method.
