Hey guys! I recently did a major service on my 2013 BMW approximately 3k miles away, we changed the rod bearings (OEM), we did a turbo rebuild, turbo lines, Engine Oil Pump Chain Kit, Timing Chain Kit N55, valve cover gasket and so on. good! I rode thousands (1000) miles with the first oil on engine, no hard pull, no over 3k rpm, and I changed oil. A lot of metal in oil of course, due to the break period, I carried out the change using an OEM BMW filter and Molygen oil. I drove a total of 2000-2200 miles with this oil and last weekend I changed the oil again but I noticed a lot of metal in the magnetic drain plug that I decided to replace the OEM, I even recommend it to all BMW owners! What really intrigued me about this was the amount of metal I found in the oil filter and also in the magnetic oil drain plug. Would this metal still be derived from the period of breakdown and wear of recently installed parts or would it be a wear problem with some other part inside the engine? At the moment he has no symptoms, no knocks, he is in great health! oil pressure is coming correctly and the car does not hesitate at any time. I am attaching some photos but I am considering the next oil change (1000) miles, sending an oil sample to the laboratory. I bought this car with 82k miles and it currently has 109k, always with a 5w40 xcess engine.

Define alot?(1st oil change after bearings replaced).
I wouldnt chance it and continue driving,get it checked.

Yeah brother, I don’t know if it’s possible classification the photos but the photos with orange glove it’s the first oil change I made after 1000 miles and the second photo of drain plug it’s the second oil change after 2000 miles with out baby drive. I don’t know if I drive more 1000 miles and change the oil again and see or if better don’t drive.

To me thats too much especialy after that mileage.Did you cut up the filter and check?either way thats too much in the oil filter housing.Rather get it checked now,if its serious they can save further damage.

[rmf30]

Yes! I atacched photos. It’s like aluminium flakes. Like a hair.

[Shirazkhan]

How many miles have you done after the last oil change?That dont look good in the pics.

[Shirazkhan]

Aluminium is not magnetic.Not sure if the screw driver is magnetic,or those shavings are stuck to it.

At least BMW dealers can examine metal shavings and determine what parts were involved. Also suggest to get a thorough inspection and soon.

Let's go, the car had an oil filter house gasket and valve cover service, after which the car was apparently normal until a malfunction appeared and white smoke came out of the exhaust a few times. I went to the same place and they diagnosed that it was the injectors, so injectors were installed but the mechanic doesn't know why he put EUR6 in my car.
The car had lean mixture errors for a few days until I discovered this myself and went back to him. He confirmed that he had installed the wrong nozzles and fitted the correct injectors, but soon after this the car started to tick a bit at the bottom of the engine, so I decided to open it up and see what was going on. There were two or three pieces of thicker metal that had passed between the bearings and the crankshaft bearing and scratched them, as well as the oil pump. We did the recommended repair and I also replaced the chains and guides, along with the turbo repair as it was leaking. After that the car was ready and I drove a total of 1000 miles with the oil that was in it after we fixed the car. I drove below 3k rpm in a civilized manner, so I had the oil changed and there wasn't much metal in the oil, it was apparently okay, apart from the fact that the new rod bearings had broken. I drove a total of 2k miles normally, sometimes coming close to the red line but nothing crazy. So I decided to change the oil again when I reached the 2k mile mark and was faced with this huge amount of metal in my engine. There are no new noises, it works perfectly, but this metal has me intrigued because it can clog oil passages and ruin everything. I'm going to do another oil change soon to send it off for analysis, because of all the frustration, I forgot to store it for sending off. I'll post new information here soon.

Did you prime the oil system after either repair as required by the manual? If not there are several instances of wiping out bearings from failing to do so. I hope I’m wrong but your rod bearings are likely toast again.

[QUOTE=E36M3;31069757]Você preparou o sistema de óleo após qualquer um dos reparos, conforme exigido pelo manual? Se não, há vários casos de limpeza de rolamentos por não fazê-lo. Espero estar errado, mas seus rolamentos de haste provavelmente estão torrados novamente.[ /QUOTE]

brother I don't really know about that, the place where I leave the car for fix its Bmw specialist but we never know. Im sad with this situation.
