In this video, we completely disassemble and strip back the cylinder head from my Turbo Mini. In doing this work, we can clearly see why the engine wasn’t running smoothly, even after the walnut blasting procedure. Considering there is still that much sludge on the intake valves, I would have loved to see how much more there was if I was able to take the cylinder head off the engine before. Also, the extra sludge on the valves would make it harder for the air to enter the cylinders, and the added weight on the valves would make it harder for the valves to open and close. Regardless, the head is off and we’re taking it apart. Enjoy!! Here are the tools and goodies I’ve used in this video.

@robwalker8530 3 года назад

I know this was three years ago, but I find it odd that you did not remove the valve seals before you took out the valves and esp before you did the milling. Thanks for the video!

@milanmastracci 6 лет назад

Thanks Daniel :) Cheap and easy way to clean out small intricate areas!!

@petemiller5813 6 лет назад

I believe that you may have mistakenly called the valve seals, the valve guides. However, speaking of valve guides. Will you be pressing out the old valves and installing new. If so, you will have to lap the valves in to achieve proper valve to seat sealing.

@milanmastracci 6 лет назад

Yes they will be lapped, and I have other valves coming in with a 3 angle grind. This engine is getting lots of love :)

@duks38 6 лет назад

Question: i notices when you you took off the head that all the valve springs were the same. i recently changed the valve cover and noticed two were compressed more then the other. is that normal? currently having trouble with 2010 mini cooper s. its cranking but not staring thanks in advance!

@therealpeterburke 6 лет назад

"more presentable cylinder head" - the holy grail of the anal mechanic's quest for perfection. I so can see myself going to town on the inside of my R53 head, but luckily, the R53 doesn't suffer the same levels of carbon buildup

@Zonedout-ou2wl 6 лет назад

Just had a mini in the shop I work at for a misfire cylinder 1 I after basics I check compression and 1 was at 0psi so I did a cylinder leak down test and had 85% leak down to the crank case. Disassembled and cylinder one piston had two cracks on the side between compression rings. Pulled the rings off and about a 1inch wide by half inch tall chunk of the piston fell off. Had a slight scratch on the cylinder wall but only visible it could not be felt so new set of pistons and rings reassembled and she purrs like a kitty.

@dkdzyn 5 лет назад

The destruction of ring lands like this is due to LSPI: Low Speed Pre-Ignition. It is a real problem with direct injection engines and everything from Minis to Corvettes are suffering from it. There are new oils coming on the market to address this issue that are expressly formulated for DI engines with less calcium detergent in the oil. It has been found that the calcium in the oil mixes with the unspent fuel and creates a solvent which has a lower octane number and is able to leak down into the rings on the pistons. If the engine is still cold and is put under stress on acceleration, the solvent created can pre-ignite before the piston is at a full downstroke and prior to the spark plug firing, thus the bottom of the ring land is cracked and eventually blown down into the oil pan.

@jafxdwg 6 лет назад

The question : With modern engine management combined with engineered fuels, how is carbon build up to the point that valves are semi seized in their guides and valve seats are unable to properly seal due to chunks of carbon deposits. Isn't this car an over engineered BMW product ? What is their excuse ?

@milanmastracci 6 лет назад

These engines work very well when they are well maintained, however they require a lot of maintenance. If an owner skimps out on something, they will see the results of that down the road. This is also Mini's first vehicle that is Direct Injection. The generations before this were port injection and they never had this problem. If they were designed with a direct fuel injector found in each cylinder, AND another port fuel injector, there would be the benefits of both systems. You would in turn get good reliability, performance, fuel consumption, etc, and you wouldn't have this carbon build up problem that regular DI cars have.

@rsiboy87 6 лет назад

All direct injection engines suffer carbon build up... just seems to be more pronounced with the german vehicles for some reason. One really effective way to keep it at bay is with a water/meth injection system. The water/meth spray flows over the valves and cleans them, much like conventional engines that have port injection, where the fuel is washed over the back of the valves.

@NVRRVN 6 лет назад

Use good quality oil to prevent "varnishing" in the head. Good luck!

@sebastianogorek6159 6 лет назад

Just an FYI: valve guides are still in the head. These cap looking things are valve stem seals. If you want your valve guides replaced they have to be pressed out by machine shop.

@milanmastracci 6 лет назад

You are right. I was just doing as much work as I could to save myself some money :)

@sebastianogorek6159 6 лет назад

Yeah man, I know what you mean ;) Are you planning to install any additional intake fuel injection to prevent carbon build up on the valves in the future? I've been watching your channel for a while now, I am subscribing now:) Keep up the good work!

@Drzdevildog 6 лет назад

How do you prevent carbon from building up in a car's valves?

@milanmastracci 6 лет назад

There are a few ways. A few ways to prevent it from building up is to install An oil catch, a PCV delete, and/or running a water meth kit. Those will all help reduce / almost eliminate that problem.

@klegolas4088 6 лет назад

very cool video with good tips to those oil channels.

@Magnus908754 6 лет назад

Great video Milan. Can't wait to see the results when you're done ;). The engine is actually not made by BMW. It's made by the PSA group (Peugeot and Citroën) so the engine is from France. I work at a Peugeot workshop in Denmark as an apprentice, while studying mechanics at the moment, so i see these engines once in a while ;)

@milanmastracci 6 лет назад

Oh I didn't know that. Well whoever made it, Peugeot or Citroën, that is one thing. Allowing BMW to accept that quality is another story. Regardless, I know mine is good now :D You're probably more familiar with these engines than me ahah

@Magnus908754 6 лет назад

If i had a Peugeot, it would probably be with this engine. Even the N/A version runs great. I think it was a great idea that you started the rebuild of that engine, and replacing the internals with better components. it's gonna be better than ever! ;)

@stephaneperigny5452 Год назад

My R60 need to be rebuild at 200K! Great tutorial!

@buddha65281 5 лет назад

I'm sorry but you still have not explained precisely why your car had a miss in the engine. I can tell you what I think it may have been just from your videos... I video #1 when you removed the intake manifold, I saw oil on the "4 intake seal... You can look at this video and see the #4 intake valve seat as well as the valve have excess carbon build up. My guess if #4 was not properly sedating and you were getting blowback... Will you please verify. thanks again for your videos.

@HobbyistLifestyle 6 лет назад

Quick question? What service manuel do you used for the mini cooper? I'm trying to buy one but not sure which one is good to get that has good detail information.

@milanmastracci 6 лет назад

@500bht 6 лет назад

I would not re-use that cylinder head just buy a cnc ported head from thumper . There expensive but well worth it .used with an agressive cam (catcam) the results will shock you coupled with a dyno tune is the way forward .If your fitting forged pistons & rods do the right thing and fit a thumper head or a RMW big valve head too.

@DeaDheaD97 6 лет назад

What tool do you use to get the valves back in? Every compressor tool I try is to big.

@baitse7676 5 лет назад

Valve guides or valve stem seals? I would think the valve guides are pressed into the head.

Should of used petrol to clean the head, much more effective. And the milling part was so extra not even gonna be seen😂.Anyways good video

But at least the head doesn't look like a blind person inspected it lol I know they're clean, so I'm happy 😁

@kodys_corolla 2 года назад

What engine is this?

@DavisSgt 6 лет назад

Are you going to do a port and polish tutorial?I've heard that that helps with carbon since it can't cling to smooth surfaces. I wonder if there is a way to add port injection to eliminate carbon buildup?

@milanmastracci 6 лет назад

100% 😊 I'll be doing that before I sent the head out to get some work done on it. I'm looking into running a water meth kit, which acts as a port injection system

@saucy3809 6 лет назад

Would break cleaner not be more effective for cleaning?

Yup i did the same thing to my cylinder head...went down to autozone bought some degreaser and washed it several timestook me one week was on vacation so was worth it.used tooth brush and picks.....a shop would have charged me upto 600 ..all i paid a shop was 75 to make sure the head was leveled

@milanmastracci 6 лет назад

Yep!! Its crazy the results you can get if you're willing to put in a bit of work

@AaronBonBarron 6 лет назад

Don't know where you're getting quotes from but an acid dip at a machine shop costs well under $100, even less if it's part of the machine work you're getting done.

@_-KOEN-_ 6 лет назад

Again I enjoyed watching. But is this really cheaper to DYI if you need to purchase so many special tools?...

@milanmastracci 6 лет назад

For the most part, I already had most of these tools. The only one I didn't have was the cylinder head organizing tool and the electric toothbrush, which was like 30 bucks. Considering what I've done in this video, at a machine shop, it would cost far more than 5 times that to get the same work done, so I think it is well worth it do do what I've done. Price out how much machine shops charge, and you will see it will be far cheaper to get this work done.

@HeldigDansker 6 лет назад

As Milan said, just consider how much a mechanic charges by the hour, and by doing it yourself you gain a better understanding of the engine, and you make sure it's done properly.
