And this thread is a perfect example of why you need to check everything over before buying an n54 in today's market. Why are there so many dishonest scammers out there?? I'm sorry but people who dont take care of there crap and push it onto unsuspecting victims make bmws look bad. Karma always swings a 360 and gets you back even worse. The amount of dishonest posrs on ways to screw someone else over is terrible for the bmw community. You bought a BMW, that has it's high costs and just because the value plummeted doesnt make it cheap. Repairs will always cost more than the cars worth.

Nothing wrong with that. Dealerships F people all day every day. Nothing wrong with #winning once.
Honestly i was joking kinda sarcastically i can't see you sneaking that past any sane person in charge of purchasing. Obviously you would never want use gear oil. I would really find out more before you do anything like that how would you feel if you sell this and buy a car with check engine light bulb disconnected to con you. I know if i bought a car with undisclosed blown engine i doing everything i can to find out if they played me like including checking forums. At that point could be legal mess or could be a psycho and just bad karma I'm the nicest person but stuff like that can bring out worst in people. This us a great community with people willing to help, you might get surprised and end up way better off than expected.
That is why he sells it to a dealership and they have to deal with it. Lemon law will protect the next buyer.
What's this "lemon law" you are referring to for used cars? In SC, if it's used, it either has an expressed warranty - typically 3 months/3k miles, or AS IS, no warranty. Some of the buy here/pay here lots, which is arguably where these cars are starting to end up - do 3 days/3 miles so they can say it has a warranty, lol. I'm fairly certain the lemon laws apply to new vehicles with the same issue 3 or more times.

You are right. I forgot that in some states it does not apply to used cars.
Wasn't directing at you just seemed like started running away and anyway didn't want him walking into dealer and having them be like wtf
For what it's worth, I have seen a rod bearing failure on an original owner N54 with around 65K on it. Car was stock aside from a Dinan stage 2 tune and owner was overly cautious with maintenance doing everything recommended plus more and usually early on everything. He had asked for a quote at my work for the "upgraded" turbos Dinan lists on their site (wastegate rattle repair done and nothing more) as a preventative measure. That kind of owner/customer. He ended up bringing the car in for a noise diagnosis a couple weeks later and it was a rod knock. Although it's not "normal" and the N54 is a very stout engine, it can and does eat rod bearings. OP, I would take others advice and take it to another good shop that is familiar with the N54 and BMW's in general and get at least a second opinion before diving into this or making a decision. Good luck!
Looks like minimal time, research and investigation prior to purchase, and same pattern after you encounter issue.

Hello everyone,
Thought that I give you guys a quick update. I took apart the oil filter this week just to see what it looks like. And sure enough as you guys can see there is plenty of little pieces of metal inside. Side note, when I was taking out the oil filter the top part as you guys can see from the picture was stuck inside the cap. If you look in my first picture the top is still stuck inside. I ended up having to hit the top of the oil cap with my hand and it ended up coming out that way. I tried with a pick tool but it would just lift one side and there was not enough clearance to get it out. So I'm not sure how this would of happen, It seems like a defective part. How does the top of an metal mess oil filter come apart so cleanly, and I'm not sure if any of the metal inside is from the oil filter from when it separated. Anyways looks like my oil filter broke off some how. How this happen I don't know, not sure if this could of led up to where I am at now. I will keep everyone posted, not sure what I'm gonna do still. using my bike as my daily, have a little Nissan but life is just to boring inside that car.

Are you using OEM oil filters? It looks like a cheap filter. This isnt the cause of your rod knock though since the filter still worked, but it just broke at the top. Small pieces of metal in your oil is bad though, usually piston rings or crushed evalve shavings if you skipped timing. The only way the filter is the issue if your filter blocked all flow to the engine which Is highly unlikely.
Have you tried running the car with a new oil filter? If the knock is gone then the filter was the problem, but statistically that doesnt happen unless it's a super cheap China filter.
I wouldn't keep running the motor like that If it is a spun bearing. Your spreading the debris from it throughout the motor and can damage the crank journal beyond repair. Ive replaced a few rod bearing on a car that was ran on low oil. Its a lot of labor but I was able to save the crank.
This is the shadest most chicken shit advice you can give. Your such a piece of shit. This exactly is why OP has his issue. FUCK YOU SIR
