In this video I show you how to perform the BMW oil Priming Procedure that must be performed anytime the oil circuit is interrupted. For any replacement such as an oil pan removal, oil volume control valve, Oil filter housing gasket, et this procedure must be performed before starting!
In the video I demonstrate the procedure using a BMW N55 engine that I recently did repairs that interrupted the oil circuit.
This is the ending of a project where the serpentine belt failed. I will post video links below in order of the repair which will include the fan removal procedure.

Thx! This tip with disconnecting the DME connector was exactly what I was looking for since I didn’t pull fuse 165 and run the car out of fuel in the fuel injectors prior to starting. Also didn’t feel like removing pipes, etc in order to get to all of the coils and fuel injector connectors either. Much simpler approach. Great idea.

Would adding an oil additive like LiquiMoly Cera Tec be advisable to the initial oil fill up (5w30) before stepping through the oil priming procedure on a new engine and for the initial 500mi. engine break in?

@AskTheCarExperts 8 месяцев назад

Hi Patrick, I would say yes to that! I have started using Cera Tec in my BMW E70 with the N55 notorious for lower end problems. I am hoping the additive will also help prolong the engine life and turbo life. Prevents direct metal-to-metal contact, thus increasing the engine service life. The low-friction effect reduces fuel consumption in gasoline and diesel engines. CERA TEC provides wear protection for engines, transmissions, pumps and compressors. CERA TEC should be added to the oil and is self-mixing. If anyone is looking for this product I will provide a link below: amzn.to/3Rnwcyj I do make a small commission if the link is used but it does not cost you anything.

⁠⁠⁠hey man I have a question, just installed new timing chain with guides, also cam ledge trays and new seals for camshafts , I turned the motor clockwise twice to see if I’m good on timing , timing is there , the car has been sitting for over a year , do you recommend priming the motor a couple times before actually starting it? Keeping the coils and injectors disconnected?

@AskTheCarExperts 2 месяца назад

Sorry for the late response, Yes absolutely do the oil priming.

@keithbailie3014 5 месяцев назад

Great video! I’m doing my OFHG and cooler gaskets soon. The BMW bulletin I read on priming talks about removing the fuel pump fuse but I’m also reading some people do that and car still starts so I’m not sure if I should try that method or not. I noticed you’re doing the manual engine cranking AND the other priming method (10 on 20 off…) is the manual turning of the engine required then? If so, what size of bit do you need to do that?

@AskTheCarExperts 5 месяцев назад

Hi Keith! Yes I would recommend the manual engine turning. This is BMW's updated procedure. I think it is a 21 or 22 mm socket if my memory serves. Best to remove the DME connector because this will cut spark and fuel completely and will prevent it starting on you. Or you can manually disconnect each coil and injector plug.

@keithbailie3014 5 месяцев назад

@@AskTheCarExperts the BMW bulletin I saw was from 2016 and like I said, it just mentions the fuel pump fuses. So does manually turning the engine 2-3x, actually cause the oil pump to pick up oil then and lubricate things? For some reason I figured the oil pump was electric so wasn’t sure what the manual turning was doing.
