My purpose is to encourage people to do things themselves!
Plus, this is a nice hobby for myself and at the same time I have the opportunity to save a lot of money by doing all the maintenance myself!
I’m not a professional with cars or motorcycles, I just want to learn how to do things myself.
If you do this service yourself, always check the correct instructions in the official service manuals. This is just my way of doing it!

Excellent as usual!
Ok let’s go !! My turn now
Handy video , thank you.
Thanks for the information, but I’m asking about the timing of oil pump and the balancing shafts, as I saw there is no need for oil pump timing , it’s only required for the balancing shafts. But according to the video there a possibility to make a mistake of one complete turn when you install the blocking metallic angle am I right?
was the old one stretched? do you think it makes sense to change it? like the upper one usually stretches after sometime
@Jani when you say replace, wash and oil the bolts - do you mean you need to buy brand new bolts for the oil pump goign back on? Struggling to find them - conrod ones seem fine to get but the oil pump ones less so! One of the torx ones deffo wants replacing as it lost some of its head coming out it was that tight in. And what do you wash them in? WD40? And il with normal engine oil? Thanks - super useful your videos as i've never done this before but getting there. Polishing the cranks at the mo as got a few marks on there - hoping i can save it!
Wont the balance of the oil pump be rotating without the crank bolt in ?
Could you share counter balance locking tool n42 purchase link?
Did you let the front frame just hang ? Only remove steering u joint ? Thanks
In our case, after a long, fast journey, the oil pressure drops. Warning lamp "red oil can" lights up. Otherwise not.
How long did it take to cure the bedplate loctite sealant? And the oil pump counter balance has to be synced to the timing of the engine right?
I don’t know exactly how long it will take for the liquid seal to cure.
BMW manual tells that; "Balancing shafts must be readjusted after installation of chain tensioner".
Exactly what this means, the BMW repair guide does not tell you.
Before removing the oil pump, I locked the balancing shafts in place with a locking tool and did not remove it until after the new lower chain was tightened.
When the engine is locked in the TDC position during disassembling and also when assembling and the balancing shafts are locked in the original position all the time.
I think the balancing shafts are then in the right position.
At least no problems have come to me in this regard.
@@JaniVoutilainen Mutta eihän sulla ollut kampiakselin pultti viellä lukittuna joten ne pyörivät vapaasti.
@@JaniVoutilainenis it possible to torque the crank bolt with no subframe attached? Thx
I ordered engine mounts and what I bought do not look like the ones on the N43 car that have some hoses that seem to be some vacuum that go up to the engine and are connected to engine mounts
don't you know what role they play?
Hi mate i liked video but issue to me struggling to understand, where you finding that maintenance handbook? Tightening torques etc. if you can tell me source you get informations i’ll appreciate you
It called Bmw TIS
@@bigdeal87 I have TIS but are there any torques for the pump itself? before inspecting the pump I need them.
Jani please an answer ... I want to open the oil pan to change the gasket to the N43 engine / the 10 mm tubular wrench cannot enter to loosen the screws, there is not enough space there between the oil pan and the gearbox ... you how did you do ?...thanks, I appreciate in advance 😊😜😎
undo the 3 bolts you see on the plate that is blocking your access and you remove cover on the gearbox and can get to them. A bit awkward to get to but I also found this issue.
@@dj0men666 You're absolutely right, I was a little scared at first that I didn't have access, ..but a day before I did this and all I needed was that protection,thanks anyway!😉👍🏻
@@Marcell-ux7rb im just waiting for my timing kit to come so i can lock it off and take the oil pump off and see whats occurin on my crank.
Hello Jani, please, oil pump tensioner has hydraulic or mechanic tensioning? Thank you
I think it's mechanical
@@JaniVoutilainen Kyllä sinne öljynpainekin menee.
The tensioner has a spring but uses oil pressure as well.
Jani, please can I ask some quick advice? I want to replace fuel filter on my N43 but I cannot locate it anywhere, have you any idea where it is?
I read on a forum that it is in the actual tank. However, other forums says it's under the car somewhere. Do yu have any advice please?
Thanks Jani
Ive heard that the n43 doesnt have a fuel filter. Only a mesh in the fuel tank to keep bigger pieces out
@@ToMsOnLV Yeah I also read this somewhere, thanks for the answer. Perhaps Jani will confirm this
Hi! There is no seperate fuel filter in the N43 engine.
The fuel pump in the fuel tank itself has a filter. And if I understand correctly, each fuel injector inside its own small filter also. These filters alone cannot be changed.
Scavenge air line on fuel ventilation system have activated Charcoal Filter (part 16137074464). But that's another thing ...
@@JaniVoutilainen Thanks Jani, I will be reasearching the charcoal filter. cheers
