FIRST OIL CHANGE ON MY REBUILT MINI COOPER S!

[@LynxStarAuto]

I've been working on exclusively German cars for 20+ years now. I would say that engine sounds pretty healthy, and the knocking to me is the injection system. Maybe some lifter tap, but overall I consider it normal to my ears. Btw a quick tip I would recommend on oil changes. I don't recommend you pull that expansion tank all the way up. The hose that runs from the tank to the turbo feed line has a plastic T that loves to break. Also, the coupling at the bottom of the tank doesn't have a guide tab. It just allows the hose to pop on. So it free spins. After some mileage, the hose will stick. As soon as you raise the expansion tank up, the stress will twist the hose, and it will want to spin. This damages the o-ring inside then it develops a slow methodical leak. Easier to remove the fresh air pipe on the turbo, and use a long extension with the 27mm. Less stuff to stress.

Remove the vacuum line to the brake booster by the pump and cover it partially with your finger, if the noise goes away it’s coming from where the vacuum pump shaft engages into the camshaft.

Ticking hydraulic lifter noise is common on BMW N52 engines after 50,000 miles or so. When hot revving engine at 3000 revs for 2 minutes can lubricate the noisy lifter and fix the noisy issue.

[@j.burton7574]

The engine in the R56 is prone to piston slap. Mine developed a similar noise at 31k after regular 3k oil changes. Exchanged it for a Honda Civic. No more noises.

[@dantheman7370]

But the civic looks shit compared to the mini 😂

[@pmcd1]

I have 2013 63 plate R56 N16 engine, it doesn't sound anything like that, it is quite quiet at tickover, it does however use the usual 1L of oil/1000 miles.

[@richtrevithick1113]

Ditch the pattern oil filter and use a genuine item (or a Citroen item which is identical, but without BMW tax added) We had a low oil pressure warning on our Cooper several years ago, after much investigation it turned out to be nothing more that a collapsing pattern oil filter. 38000 miles later, and the engine is still sweet as a nut....

[@GeorgeAusters]

Yeah i've got a genuine purflux one to go in at 1000 miles

[@boazplays7239]

My mini makes the same rattly noise when cold too. I've always heard that it can be normal, but keep in mind the "death rattle" that can happen if your timing chain guides start to fail. I started running 0W-40 oil and it seems to help a little.

[@GeorgeAusters]

It has all new timing gear👍🏻

[@Hitmanzero47]

Timing chain isn't an issue at 500 miles after being rebuilt.

[@AutoRevisieOutOftheBOX]

Becuse the story of your dipstick, i hope you install the timing chain correctly becuse the plastic chain cover, so i think, when you use the chain spanner instead of the dummy 0.06 d.a.n, when titening the chain the cover is not straight give noises and the dipstick is maybe not propperley fitting

[@F06M6]

Does sound like a lifter. Sometimes they just are "like" that. N14s are incredibly noisy, valvetrain wise especially. Some of it comes from the VP or HPFP. You can do a bleeder lifting procedure Procedure preconditions: Engine oil level correct whilst warm- neither underfilled nor overfilled Engine running at operating temperature 1.) Bring the engine up to an operating speed (no load) of 2000-3000 rpm and maintain this condition for three minutes (bleeding procedure). Let the engine idle for 15-30 seconds and reevaluate whether the noise is still present or not. 2.) Engine quiet - procedure is finished. 3.) Engine noise is still present - repeat the procedure; perform steps #1 and #2 up to a maximum of 5 times. 4.) Only if the noise remains after performing the bleeding procedure 5 times: proceed by performing the procedure for a final time, also at an engine operating speed of 2000-3000 rpm, but for a total time duration of 15 minutes.

[@F06M6]

Something to mention here, in the shop, we place a high flow fan in front of the car in order to keep it cool-

[@GeorgeAusters]

Yeah that’s what I was thinking of doing or taking it for a good hard drive. It has a brand new HPFP and VP 👍🏻

[@teifear7528]

I now a little of petrol engines but that noise tells it's some hydraulic lifter ticking stuff. Should be Easy to fix.

[@LeedsHypnotherapist]

Have you tried Forte Top End Treatment? That's good for rattles

[@GeorgeAusters]

I don’t believe in oil additives much

[@LeedsHypnotherapist]

@@GeorgeAusters if it's the lifters it's really good for that

[@9585sam]

Mine is the same after rebuilding, not sure what it is but i did have a similar noise on my 335i which ended up being the mann oil filter sucking itself in. May try a genuine filter.

[@GeorgeAusters]

Yeah i'll be using a genuine purflux filter at 1000 miles so we'll see if that makes any difference

[@LynxStarAuto]

Mann is the OEM filter on the N54/N55. You sure it wasn't a counterfeit? Plenty of issues with fakes around. You have to be very careful.

[@mickeymini9522]

The noise will be the vacuum pump, might find replacing it reduces the noise level.

[@GeorgeAusters]

It’s brand new👍🏻

[@Hancock_nl]

Hmmm it sounds definately different compared to first startup. Maybe buy a cheap stethoscope thingie and poke it on various parts while engine is running. Would not hurt to do a compression test or leakdown test just to rule out any errors there. Good luck 👍

[@31docdoc]

Exactly same noise on same engine on my Peugeot but with 120000km Normaly these sound comes from the timing chain, when the chain is loose or the chain tensioner is bad, but everything is new on this engine, so i'm little bit surprise Interessting to see if you find where it comes from Sorry if my english is bad, i'm from France ;)

[@wakeskimming]

I have rebuilt mine at the same time as you, mine does not sound like that, but has other problems. It sounds to me like a lifter. remove the valve cover and crank it.

[@GeorgeAusters]

Interesting.. what other problems have you had?

[@jimmygee1969]

I’d recommend the Cravenspeed dipstick, George. Pricey but worth it - I’ve heard of the OEM one snapping off when half way out!

[@GeorgeAusters]

Ive considered it but can’t see any difference to the cravenspeed one and the ones from China

[@jimmygee1969]

@@GeorgeAusters agree-wasn’t aware that others had now copied their design at 1/6 of the price!

[@LynxStarAuto]

The JCW dipstick is the best option. Factory part, with big improvement, and costs less than the Cravenspeed.Thing is, it might be discontinued I heard, and what's left in inventory is what's left 😢

[@davehughes6501]

My mondeo has a peugeot engine aswell and although the dipstick is different it is also abit of a fart.

[@GeorgeAusters]

Will definitely be upgrading it!

[@chrisfarr9983]

The vanos valves can tap a little.

[@deanrobinson3210]

I had my timing chain changed and I didn’t know you should do the vanos at the same time, they didn’t say nothing and ended up doing a bad job of the chain anyway 😡 ended up taking it to a professional garage to get it sorted

[@GeorgeAusters]

Has a new vanos solenoid and check valve :)

[@FlatEric971]

Mini oil dipsticks are the worst. Used to drive me batty just trying to check the oil level

[@GeorgeAusters]

Honestly!

[@barryhall7]

Mine sounded like a bag of spanners as well. Apparently it's normal.

[@philipslater9450]

Sound's like hydraulic lifter to me. My mini with similar engine doesn't make that noise. As you say give it a good run and hope it goes away.

[@GeorgeAusters]

That's the plan!

[@Simontrebilcock]

Is that the vacuum pump making that noise?

[@GeorgeAusters]

It could be!

[@simonh870]

The rattle could be the high pressure fuel pump.

[@GeorgeAusters]

It’s brand new

[@nistorz]

@@GeorgeAusters This is the normal sound of it. Have the same sound on a new pump.

[@dantheman7370]

My high pressure pump ticks too, also ticked when it was new and still ticks occasionally

[@dantheman7370]

Mine sounds the same

[@TurboTimsWorld]

As mechanic of 30+ years its funny how your ears work and with video/stereo sound on the tube Ive nailed it down to....Erm are scratch chin...expensive LOL no go with the dog cog on the vac pump then work your way back to the lifters the sound on the mic is not good enough (not its a poor mic set up its the wrong muff the tone is wrong)

[@deanrobinson3210]

Love your videos mate just spraying my subframe at the mo. That knock noise has drove me mad I was praying you would know what it is, a lot of minis have it but it can’t be normal 🤷🏻‍♂️ one garage said it could be vanos? and like the comment said vacuum pump? I know nothing about mechanics I just keep having to pay out for things and hope

[@GeorgeAusters]

I do know the vacuum pumps are supposed to make a knocking noise

[@GeorgeAusters]

Good luck with the subframe too!

[@colinscutt5104]

it does sound serious but microphones can be misleading and the oil was fine so it cant be as bad as it sounds

[@dantheman7370]

@@GeorgeAusters I’ve put a new vacuum pump on mine too, still sounds like yours

[@GeorgeAusters]

The vacuum pumps are supposed the making the rattle noise, it’s normal👍🏻

[@boothy4879]

Sounds normal on Idle they do have a rattle.

[@GeorgeAusters]

Noted cheers👍🏻

[@jasonleeandersen]

It should sound kind of like a sewing machine.

[@MegaReddevil71]

Wouldn't put fully synthetic in yet not enough miles

[@GeorgeAusters]

What makes you say that? It's as run in as its ever going to be

[@leiflillandt1488]

​@@GeorgeAustersA month ago I bought a 2011 (12?) F25 X3 30d. Once it was new! The first owner changed the oil after 33,000 km! And ever since the oil has been changed at about 30,000 km or slightly less. Now it has 246,000km. I don't think much has been done to this car during all these years. Brake pads two times, and two bushes in the rear link arms. A big question in this case is of course, how long will the engine last? Another 100-150,000 km?

[@MegaReddevil71]

Can take more than 500 miles to bed rings in would still take it easy but not as easy as the first 500 miles fully synthetic oil slow the process down personally I would have done 1000 miles at least before using the synthetic oil

[@pmcd1]

What brand oil and version used in this oil change?

[@GeorgeAusters]

Where are you getting your information from? Rings will be bedded in after 100-200 miles👍🏻

[@jamesgarage4327]

Your dipstick shouldn’t stick like that removing it - you may have something unintended in the oil pan

[@GeorgeAusters]

It’s just the nature of the design, the dipstick goes through the timing chain guides

[@jamesgarage4327]

@@GeorgeAusters maybe my N18 has a different design

[@GeorgeAusters]

The upgraded dipstick just drops straight in and out

Don't sound to cleaver does it.....bloody good show though young man

[@GeorgeAusters]

Hopefully it's something easy!

[@derekgb3780]

My wife has one. These French engines just aren't the best

[@spikepike42]

Normal mate mine sounded like that before the rebuild and after. Just your typical n14 engine sound unfortunately 👍

[@GeorgeAusters]

Interesting👍🏻

[@t5jerry]

NO. Engine is " run in" at 500 miles mate, 5k- 10k is more like it.

[@GeorgeAusters]

Nah mate piston rings are usually fully seated after the first 100 miles or so👍🏻

[@t5jerry]

@@GeorgeAusters piston rings " may be" , engine isn't.

[@GeorgeAusters]

Piston rings are the only thing that needed running in. What else would you expect to run in?

You havnt left a spanner in there have you...ha just kidding I know nowt about the mini engine.

Maybe 😅
