Was The N20 A Mistake? BMW Tear-Down: Opening up the 328i Engine and Cooling System

► Creating something worthy of BMW's motorsports heritage from one of their more standard offerings was always going to take a few parts. Just how many, though? We're about to find out.
Digging into the F30 328i for the first time is going to reveal everything it has and needs. Thousands of miles of ownership have taken its toll on the car, and left more than a few things to address immediately. With little time to waste, Gareth tears right into the project to prep it for its makeover.

I own an F30 335i, but I'm still going to watch this, because Gareth working on BMWs is highly entertaining!!

Man, if you pull one of those mickey mouse hoses off without it breaking apart, you may as well go buy a lottery ticket. I've pulled like 50 of those in various F30's, E90's, F10's, etc and not a single one was even remotely intact, and that's including cars with 70k miles on them. The plastic cooling system components really do not survive out here in Arizona.

About to replace this mickey mouse hose (upgrading to an aluminum one) flange on a 115k mi N55 that also need a new valve cover and gasket.

@dylangomez562 Ай бұрын

I'm in SoCal and surprisingly did mine 2 weeks ago on a 95k mile N26 and I had to cut my hose because I couldn't get that flange off. Was surprised it made it that long.

Needed an excuse not to do away with my little 175k mile 428i. Cars had it's issues, timing chain, thermostat and compressor being the heavy hitters. But routine maintenance on the rest of the smaller preventative measures like arms, bushings and gaskets have kept the car going fighting the Texas heat. Appreciate you guys giving the n20 some love. The M54 in my 330ci has proven itself and looking to see that the L5 in the junker V70 T5 I just picked up can do

I’ve owned N20’s, B48’s & B58’s. The N20 is by far the least reliable, but I wouldn’t say they are terrible. If it weren’t for the timingchain failing, which is a big failure, this engine would be solid. I’ve only had my thermostat get stuck open and had to be replaced. Due to gearing, a lot of these 28i’s cars feel quicker in the lower end compared to the 30i’s cars with the B48. Outside of that, B48’s are a much better engine and I am glad to see BMW was able to improve the N20 into what it is now. The N20 is definitely an interesting engine, seeing that’s BMW’s modern day turbo 4.

@fcpeuro-media 20 күн бұрын

B48 is for sure a sweet spot, but with so many N20s out on the road we might as well learn to love them for the long run!

@losertown2785 Ай бұрын

timing chains can feel lose at times due to the tensioner not having oil pressure to apply pressure and due to where the cams and crank are at but id say its definently best to do it while your there then take a gamble on a 100k+ mile set of original chains.

Why does BMW not just key way all Tom mg gears and crank timing items? It would be so easy.

Awesome video, more so because I own the same car... Would you guys say that the timing chain is the only major reliability thing to worry about when it comes to the N20?

Its for sure "THE BIG ONE" other than that most of the other things we mentioned are pretty typical of most modern BMWs.

@@masinicustefan I have a video against 328i and also some slight acceleration videos. The difference is absolutely huge as the stock car boosts only 8psi and stage 1 20psi so it has way more torque and hp at all rpm ranges My car did 6.9 sec 0-100kmh stock and now 4.8sec Im xdrive though
