I work in a shop that services BMW's. I've owned four of them, and will soon be buying my fifth. Two of my co-workers have one. However, if there's one thing we've all learned, is to stay away from the four cylinder engines. The problems start with the timing chain guides, and end up with a catastrophic engine failure. This looks almost as if it's programmed to occur just after the 100,000 kilometer mark.

a good service whit this engine, and it's the best !!! ;)

[@zahkam7322]

11:20 So that Rattle noise at startup is normal!

[@jacx11]

n42b18 here. I'm adding 0.5l of oil every 1000km. Engine mileage is 100,000km. Sigh...

[@freelan89]

This is the n42b20 engine.

[@giorgibuzaladze844]

BMW N42/N46 need Replace every 100000 km Valve Stem Seals and chane. so You will not have an oil expense. and eny problem. its very good engine. need longlife oil too.

[@minilogoguy18]

LOL, the whole point of a timing chain is that it should never need to be serviced. Honda chains outlast the rest of the car.

[@giorgibuzaladze844]

@@minilogoguy18 honda engine is legend.

[@4539716]

why this engine consume so much oil? piston rings problem?

[@Jack-qn4vt]

If it's smoking when accelerating after leaving engine to idle for 5-10min then valve stem seals, very common

[@alvin5603]

[@archermo3215]

[@michaeljoslin5598]

Why aren't any of those techs wearing safety glasses?

[@ahmedza9303]

[@KDOS_SSDD]

N20 is so much better than this

[@blame182]

n20 is indented to change 6cyl, of course it is better. n13 nowadays replaced old 4cyl
