I Found The Best Kept Secret In BMW Engines!

[@workwithjp170]

Just want to say that I just recently bought my first bmw , a 335i e92, and I found it has a ton of issues (after buying, of course) and the dealership quoted me $14k+ to get it running well again. I’ve been binging your videos to help educate myself to do the work at home and they have been super helpful. Thanks for putting so much effort into them 🙏

[@VehicularDIY]

Glad to help, that's why I do this. Thanks for watching.

[@LucidLoki]

Definitely want to do a complete cooling system refresh.

[@BozoBlaster12]

A LOT of routine maintenance, I'm gearing up to do a valve cleaning here when I find the time, oil blow by gets into the intake tract and creates carbon build up inside the intake valves choking off air flow to the engine. I took the manifold off and LOTS of carbon crud on the walls and valves themselves, an upgraded PCV valve and oil catch can should alleviate the build up but it still needs to be cleaned.

[@teekay_1]

I thought the secret was that they all end up leaking oil.

[@BozoBlaster12]

They do, the oil filter housing gasket will eventually fail, leaking oil down the front and drivers side of the engine, oil will get on the serpentine belt and over time saturating the oil and stretching the belt which can then result in it slipping making awful belt squeaking and then it can slip out and get wedged in between your harmonic balancer and push its way back the front main seal I to the oil pan, and if your lucky the power steering pulley might hit the subframe from hitting a pothole and breaking the guides for the pulley and can shred the softened belt up like it did to me! Which can also push pieces instead of the whole belt into the front main seal. It's a plastic pulley like everything else so I replaced with an aluminum pulley. If you don't replace the gasket this can all happen and lead to catastrophic engine failure.

[@VehicularDIY]

Thanks, I only found one guy pushing the platform but he started with a 330e which means the pistons would be the limiting factor and the hybrid assist would skew the numbers. Nobody pushing the standard engine which shares the pistons and rods from the B58TU which go 700+ HP.

[@chrispetty5058]

The only failure I’ve seen to the balance shaft was from a customer over revving to 9k. The idler sprocket wobbled off the bearing and broke through the side of the block. The rod bearings were in good shape.

[@VehicularDIY]

Good to know, thanks

[@mike_oe]

How is it possible to rev to 9000rpm??? The rev limiter should prevent that. Only way to do that would be downshifting a manual in the extreme, but there are not many manuals left, if any with the later engines.

[@aztecvspec002]

Glad I found this video! I have a G42 230iX and so far not many channels have touched on modding the B48. The B48 in the Minis get love but not so much on the BMW side. Def looking forward to following your build.

[@princeali316]

My favorite BMW engines overall were the N52, N55 and B58. N55 was very reliable, especially in the EWG and M2 variants while being tunable as you mentioned, and the B58 just improved on every aspect into one package. Just my opinion and experience from owning all three. B48 is also giving me a good feeling as a quality engine.

[@bmwlane8834]

I totally agree! I drove my 2005 530I 400,000 miles...the car was great. Now I'm in a 2019 430I b46/48 engine....I'm blown away with it. I went from 6 years saying I would never buy a 4 cyc. to now....Mercedes metris van(4 cyc.)..which I love...moto,camp dog rescue and everything else, wife X3 and my 430. All three of our cars have the same cylinders as my old 850i lol.

Just found your channel and instantly subscribed. I love when people actually know what the fuck they are talking about. You sound very competent and experienced, unlike the majority of clout chasing youtubers who can barely change the oil. You don't need an M2, m3 or m4, this is something I've been saying for a while now. I've been tracking my 230i and absolutely dominating with my b48 engine. I was skeptical about the power at first but it is more than adequate. Glad I got a b48 because the handling characteristics from the lighter front end is better than a MX5, and GR86. It is that good!

[@VehicularDIY]

Thanks for subbing! There are two places where even stock it impresses me, sometimes if you hit the torque just right at around 20 mph it'll put you back and from 80 to 100 mph it really moves. Might be going into an over boost. The lighter front end really sets it apart, the G80 M3 had an amazing front end but you could still feel the weight. The M340i felt clumsy at times, if you get it wrong that back end would want to swing around quick.

[@boostlee876]

Nice key point to mention the N55’s potential if it had forged internals. The M235i and OG M2 have forged connecting rods and forged crank so power potential is substantially higher than with a 335i N55. But because of the N55 being sandwiched between the N54 and B58 the N55 ends up being underrated and overlooked.

As a last gen F30 328i owner right before they introduced the B48 and 330i name (again). I always wondered why there was no major performance parts for the 328i. Other than those early N20s having that timing chain failure looming overhead the final year of the 328i was the N26, still open deck etc but no timing chain issues, and some other throw ins for reliability/efficiency. For the 4 cylinder community this is one of the few vehicles that has a longitudinally mounted engine that sits behind the front axle. It’s such a fun car to drive and handles great. Compared to some of the understeery fwd “fun” vehicles. Plus I agree with your take on the pricing of the 330i and M340i. It’s tough to find a low mileage example of the M340 for under 45k. Meanwhile I bought my 2016 in 2019 with 16k miles (spotless carfax) for 25k. BMWs are BMWs and they’ll still do BMW shit but my car has been reliable since I’ve owned it. Tires, oil change, and brake fluid change and bleed is the only maintenance I’ve had done but I am just hitting 56k miles.

[@VehicularDIY]

Yes just needs the fueling system upgraded where the G20 has a stronger fuel system for emissions compliance.

[@309gti8]

I can’t thank you enough for such an informative video. I wouldn’t be modifying this, just curious about the reliability as a daily driver for years to come. I’m concerned about the timing components being at the rear, but I do feel better now knowing that the balance shaft is gear-driven. I believe these have 3 water pumps, which also seems a little concerning for long-term reliability, but on the other hand, it’s good to see cooling is a priority.

[@dinosoarmotorsports]

I agree the 4-cylinder BMWs are way overlooked...everyone wants power and xDrive, so M340s and M cars make sense for them. But you lay out a great argument for modding a B48 car and you'd have a lighter car, and better turn-in too...imagine a great handing BMW! I have a 2022 230i M Sport and am excited to get even 300 RWHP, but maybe an easy 350+ would do me even better. Great video, thanks! I'll be watching all your upgrades.

Thank you for this video. It affirms that Bmw hasn't made a good reliable 4 cylinder engine in a long time. The main failures of most 4 cylinders from most manufacturers now are balance shaft and chain failures. Vehicle manufacturers are going down the Colin Chapman route. But instead of making them last till the end of a race, it's now keeping them running until the warranty period is complete.

Main caps are the main weakness in the B46/48. They should be 4 bolt per cap and extend the width of the block to aid in crankcase rigidity.

I'm curious to see what turbo you get, I've been eyeing the Pure Turbo.

In the same boat as you man got a 320i stage 1 plus I call it. Cause its literally the same as a 330i stage 1 now! Crazy right

[@yearight6294]

man im excited to see more from this engine/car . i miss my e90 and e92 so much im looking into buying of these asap.

[@dhjhi]

Awesome explanation and analysis. Does any of the BMW X3 SUV have any of these engine?

[@phoenixosprey7455]

The balance shafts in B48 are 1:1 from N47 diesel engines. The same concept.

[@brandonwallace9059]

Yup after already knowing this and you owning an m340 and still wanting to mod the b46 just sold me to full send🤝🏾

[@davec5237]

Great information. Thanks for sharing. 👍

[@ravszee]

[@shhhpark]

Glad I finally moved on from my N20 428i...was always a concern to me and finally moved on to a b58!!

Great video and project. Long time viewer that appreciates the return to a more original DIY content…IMO 👍👍👍👍

[@VehicularDIY]

Thank you. Yeah being alone with my thoughts in my garage sometimes can be nice.

[@LordHolley]

I don't even think anyone at BMW would argue that Honda makes the best 4 bangers. So why not copy the strengths of a K-series, fix the weaknesses, build your own engine that is better, and build legends in the process?

I am a new subscriber and simply want to praise you for the informative and helpful content of your videos. I came across a video of yours from approx 5 years ago titled long cranks on your E90 if i recall correctly. After beginning my research on an issue with cold cranks on my 2007 328i. I am thinking it could possibly be the fuel pressure regulator.

[@VehicularDIY]

Thanks for subbing and for the kind words! Yeah it's one of the first places to start on a long crank. If its got over 100k miles might want to just replace it for maintenance anyway.

[@ALEXNERI3]

@@VehicularDIY Yes sir, thanks.

[@6ixvamp]

This was extremely informative. I learned a lot from this, thank you 🙏🏾

[@grahamharris7010]

got a 335i e92 like 8 months ago, took it for a major service when I got it and it was well looked after 97 000 kms on the clock. So far it has been treating me well and drives like a dream. Standard kept except for miltek exhausts but will add aluminum charge pipe eventually. Here in sa we do not have issues with the HPFP but I heard this is common in america due to the petrol ethanol ratio's or something to that effect.

[@leosam6824]

Nice video! Very informative! Would you be interested in doing a k swap video into a e90 or f30 chassis?

[@VehicularDIY]

Thanks! I didn't know that was a thing, can you link me to anyone else doing it?

[@leosam6824]

@@VehicularDIY You would be the first if you consider doing that swap
