I'm right in the middle of replacing my head gasket on my grand cherokee 4.0 I6 but after watching you do this fiasco I don't feel quite so bad there is no comparison. Cheers from Jacksonville Florida
Curious as to why no valve clearance check?
@17:25, if you have the correct tool – the angle gauge – why just try and estimate it with the breaker bar? Isnt using the angle gauge just as easy?
step 1 and only step:buy a honda
I know if I was doing we would have leftover parts
It looks daunting and tedious, but I think I'm up to the task.
33:56 too much coffee ?? :))
sounds like a diesel engine
Do you know by any what's the estimated cost of changing the timing chain vanos and vvt on a mini 2008 and what's the average labor fee?
Man Eric you are an automotive genius. I don’t think a doctor has any more total knowledge in their head than you. Great video!!!
Thanks Eric for your video this way I'll make sure not to buy a mini Cooper.
woo wowoouu wwooooou you must decompress all lifter.
at min:14:45 do i always have to put the pistons at neutral and same position like here? i need to replace the head gasket. thanks in advanced Eric
sound like a diesel engine
Here is little trick how to install very fast the keepers. I know your system are bit different but you have a tons of more space than my installation had. https://www.youtube.com/watch?v=hnYXvgdCEiw
The fastest speed what I was able to do that job was about 43 seconds, remove the valve, oil it and install back. On the camera it is bit slower but still good result.
My mini has the N16 engine, I’m good right?
No disrespect but that engine sounds like shit
It sounds like crud. . Do a compresion check . Did he regap the valve rocker ? I didn't see it .
I own a 2007 r 56 s and its crap ……crap crap crap….Do not buy Crap ….
16:18 ahhhh the satisfying drop of a cilinderhead falling into place
thanks for you video. do you think bend valve cause by timing fault?
Great info i have an r52 with w11 engine and i have thought about getting a mini with a n14 what mileage does the chain normally fail
Eric your the best very chingon my friend
Maybe you didn’t show it all in this video,but I’ve never seen a timing chain removed without the timing cover taken off and same with installation..to get the timing correct at the crankshaft you have to be able to see the timing marks it’s impossible without the removal of the timing cover.
I thought that extra 90 was only for the bolt for the timing chain @.@'
edit: Never-mind…was ahead. ^^,
Installation of camshafts while 2 open valves are supporting the whole head on the table. Cleaning DI injector tips with carb cleaner and a brush. Lubicating teflon rings. Using the most important crankshaft stress bolt a second time…
Please people, don't try this at home …
Service video send me
Hi Eric may i ask how long a time duration it was from the time you first fitted the new chain and guide rails till it bent the valves,like was it over a period of time or did it happen on fireup? Also how you did torque settings on the cams and crank bolts is exactly how i used to adjust the rocker arm/pushrod adjust on my old small block chev? Good job by the way congrats
I have the same car, the Peugeot engine is problematic.. most problems with these are the high pressure fuel pump. thermostat housing..turbo oil feed pipe(I have replaced all of them) on my 2007 cooper s r56 n14 engine..
That engine sounds so rough guide & nothing like a mini 1598cc. Hilarious but the truth about mechanics.
hi Eric ive just replaced my r56 timing chain as it failed on an emissions test over here in the uk, was showing as the cam sensors advanced timing errors etc, chain was slack and the guides was all brittle, on starting engine with new chain kit and tensioner it is throwing approx 4 vanos codes up and the engine is really flat on acceleration, is there anything i could have done wrong or is there anything else i need to do after changing, help would be much appreciated thanks in advance Kev
Did the motor start running smoother after driving?
What causes valves to bend and what if anything would prevent them from bending? Your a true mechanical genius!
He's is gonna work with new headbolts and head gasket i hope???
Awesome video can u do a tear down on a mk2 Yaris that would really helpfully as I’m having problems with mine….
Eric, you are a legend sir !!!
I’ve recently discovered your mini series, and it’s been absolute gold for me – I’ve had a troublesome mini that’s been on and (mostly) off the road for a while …..and thanks to you videos I’ve managed to get it back up and running better than it’s been for some time !
Thank you so much, you’ve saved me a fortune in garage fees and what’s more I’ve discovered a love of back-street mechanics that I never knew I had ! Keep up the great work and take it from me you certainly live up to your hero (and mine) Ed China !!
All the best, Steve. Yorkshire, England.
I think your wiggling your dipstick around a little too much
You Sound like the guy from dirty jobs! Mike Rowe
Runs like crap! Well done BMW!
with the cost of maintenance on any car, especially the Mini. I have tackled a lot on my own. Just did a trans swap a few months ago, and now need to do a timing chain on my 07 Mini. Thanks to videos like this and having some mechanical ability I am not afraid to tackle those tasks. Besides you can still put it in the trash if its in pieces and doesn't run. What have you lost?
I do not suggest spraying break cleaner on aluminum. Chlorinated one specially creates a harmful gas which you breath. Try Purasolve break cleaner. At least it has lower toxicity then some others.
thanks for sharing ,I do have question what number of wrench do you used for serpentine belt bolt thanks.
Hello, To change the bent valve do I have to take whole engine out of the car? Or I am able to take the cylinder head by keeping the engine inside the car? Thanks.
Greetings.I am from Slovenia and have a good time following your contributions.A second time I apologize for my English.Now to the problem that I have.Last you serviced a mini with 1.6 thp engine with n14 if I know well and now I wonder if it has peugeot rcz 200 the same type of engine? The engine started to smoke and drink more oil than before 1l 1000km.Sumim on teflone.Thank you and so on.
@erikthecarguy why is it okay to have oil in the head bolt holes but not water?
you didnt turn the engine by hand minimum 2 turns? cant believe this its basics when doing timing jobs
Eric your totally awesome dude !!! Hats off !!
What was the reason thats the engine was shaking after The Start?
