Hey john here from the netherlands, special thanks for posting these kind of video's about the n43 engine. Learning a lot sinds ii bought one myself , 3 days after pursues the car i start getting trouble true inside computerscreen oil pressure .. Can't even drive anymore so.........
@@johnvandenbroek9926 i will have a video on oil pressure regulator soon. But could probably also be broken chain guides, clogged oil pickup, oil starvation. Check oil filter for plastic debris.
Whole life i drove used cars but had zero knowledge off car mechanics (even my first car was used Yugo from 80s) and i had always 5-6 used cars in same time and had 0 problem maintaining them ,but when i bought my used BMWs (X5 E70 and E93 with N43 engine ) now watch mechanics videos every day ,on X5 car engine died after just 2000 km (40D) with out any warning ,no codes at all just died instantly and N43 after 5-6000 km low oil pressure when engine heats to 96-100 Celsius but car still run normally
Ive just done a rebuild on my n43. First engine rebuild. Never done it before and very little guidance out there. Wish id had these vids when i was doing it. I think ive done good but the oroofs in the pudding. Just got wngine back in and on box and reconnecting everything. Fingers crossed!!
You can replace a oil pump with a simpler one without the heavy and power robbing balancing shafts from an N43B16 1.6 litre engine. The crank no start could also be caused by a faulty reluctor(either crankshaft or cam sensor)
Hello, love ur video’s. Could you please help us. I have a 1 series e81 N43b16 and my lower oil pump chain is pretty loose and i have oil pump problems. We found out that the oil pump sensor is defect but we want to know if the chain should be tight or not?
Should be prety tight but it also depends on if tensioner is filled with oil and if chain is under counter tension. Check out my N43 rebuild video series part 1 where I assemble oil pump.
Hi I have exact same problem spun bering cylinder 4 and crankshaft to be replayed did you buy used in good condition or new ? I seen some offer on eBay new crankshaft but a bit afraid of them Thanks for vid
That is stated in the BMW repair manual for this procedure. However, I think that this is just a standard procedure to avoid any complications when doing warranty work by BMW. In a DIY setting like mine I think I could have used just one rod from the donor engine and all would be OK. The problem could arise if the replacement rod would have significantly different weight than the other 3. In that case it would be possible to weight match and balance them, but that would mean more work:)
@@BimmerZen Aaah. Thank you for the answer. I would think if original replacements are used that, given german engineering, it's unlikely that there would be such a weight difference to actually create any problems... Since I'm replacing 3 conrods I hope this to be the case.
Hi, Are you based in UK? I also have a N43 engine 3 series 2008 and to start my car it takes a while and then it works. However during driving when I accelerate it causes serious hiccups.
Oh damn! I love these N43 units. Been keeping me busy for the last 15 years lol. Nice video buddy.

And how did it go ? If i May ask ?
@@johnvandenbroek9926 running great so far! En route to 500 mile service on ruuning in oil. 🙂👍

Could you also provide some codes for the latest revision of tensioner and other timing parts?
How mutch kilometer ?

@@Gogolxd i managed to find good used bottom end so i swapped crank and conrods.
Nice job man!))) Can you please tell me what is the clearance in the connecting rod bearings? I have 3*0.05 and 1*0.055. Is this normal?
Large connecting rod eye (without bearing): 53.600 ... 53.616 mm
Radial conrod bearing play: 0.025 ... 0.070 mm
@@BimmerZen Thank you.
Can you explain around 48:45 why all the conrods have to come from the same set?

Not in UK, check for errors with compatible scan tool, I would suspect injector issue.
Can it be vanos problems? I am from the netherlands..........
How many km on the clock?
216.000
