Completely Disassembling a Mazda 2.0 Duratec MZR Engine!

I've never disassembled an engine before, and having the extra 2.0 in the garage I thought it would be the perfect opportunity to learn! I spent a couple days removing camshafts, pistons, crankshaft and the other bits from the 2.0 Duratec MZR engine. It was super fun and I hope you guys find it as interesting as I did! Stay tuned to the end for a giveaway announcement!

Tearing the engine apart does nothing but builds your knowledge and confidence. Good job Action Jackson

[@saifaldeen2005]

Hey man you doing great! 👍🏻 I hope you make a video to address the issue with the Engine cover gasket that get a lot of heat from the exhaust and they lake oil every couple months it’s a pain specially the bolts under the Cowell i don’t have a proper way to take them out 😫

[@ron7665]

isnt on the side at the bottom a bolt you can remove and stick a special longer bolt in, to lock the crankshaft?

[@Horatio4711]

Yes, you can, but only for timing the engine, not for unbolting the pulley. Just hold the pulley with the appropriate tool.

[@gordoncox8082]

Oof, the way you took it apart was brutal but seeing you were not going to be putting it back together, it doesn't matter all that much. If you were going to rebuild one, there is a lot more that goes into it like keeping track of where the parts came from, all the valves need to go back where they came from, all the valve covers ( buckets/shims) are specific thicknesses and need to go back in the same place as well as all the bearing caps. It is cool to take one apart and see how it all works together but even cooler building one from where you left off and having it run when done and it sounded like you might have that in mind with a 2.3L or maybe just a swap which I think I already saw a video of you doing a swap awhile ago. I know this is 3 years old but am in the middle of a 2.0L mostly forged build for my 06 and looking for any tricks people have to pass on and came across this one. Very few 2.0l engine videos available. Keep making your videos and keep learning. Preston told me to say hi from GA.

[@BZXT]

Great video bud, very informative for fellow nc owners. Thanks for your effort of filming and posting this.

[@ColoredinLight]

Appreciate that!

[@BeyondEllisBeck]

Hello sir, I'm very curious as to why there is little to no aftermarket turbo parts for this engine? Other cars with N/A 2.0L engines have the ability to do 300-400whp on stock internals but this engine seems underpowered. My 2007 Mazda3 has a 2.0L VVT but I see absolutely no mods for it. Why exactly is this?

[@przemekilski3939]

There is a special tool for Crankshaft dissassambly, but funny way you did this. Just don't do that way, if you want to reuse the engine, or you'll mess it all up.

[@ColoredinLight]

There is a special tool, but this method works.

[@pazak_bi]

Thanks for the video. Can you show the pistons in detail please? Are there oil relief holes? It is said that the 2006 2.0 Miata didn't have these holes and this is one reason that contributes to the notorious oil consumption problem that occurs in some cases. I don't know if it has been fixed with the face lift in 2008. The 2006 should have a pressed piston pin while the 2008 version can be disassembled because it has a free floating pin. The 2008 LF engine also has a forged crank shaft while the earlier version was cast iron. Also is there a reinforcement ring inside the piston?

[@zfreak2808]

you saved me with the video. I didn't know which way the rod caps went. I had them backwards initially and my plastigauge readings were terrible! The pointy end goes forward!

[@andusensei]

Really interesting to see an actual teardown of a 2.0. Great stuff as always.

[@ColoredinLight]

Thanks!

[@galimcan06]

I couldn't understand in the video, is the block aluminum or cast? It looks like cast iron, the block I have is shiny aluminum, looks different, could be dirt too.

[@coinkiller5495]

Hi bud that motor blow it’s head gasket on 1 and 4 you can see it looking at the block and then the gasket and it you look at the bottom of the head and also the cam caps you took off you never take them off and mix up it’s bit now. You place them in order and way you take off remove cam and then put caps back on so you don’t forget witch is witch

[@lowell123]

Me personally think the motor is in decent condition. When it comes to overheated motors the main thing to look for is the crank and rod bearings to see if the oil and coolant mixed to the point where it wasn’t enough to line the bearings/journals. But from what I see I don’t see any bad marring or gouges so I think it’s a great contender for a rebuild to learn from! It’s really simple to read/follow a repair manual when putting it together. Have fun!

[@ColoredinLight]

One thing I didnt show was the piece of piston that was broken off near the piston rings, the pistons weren't in great shape and the previous owner said the engine was overheating. Definitely not getting a rebuild.

[@razgriz1229]

Brother you’ve come so far ❤🎉

[@terryfleming7084]

Taking it apart is the easy part. You need to read a GOOD repair manual before you even think about putting one back together. You have a ton of clearances that must be spot on for it to last.

[@ColoredinLight]

Yep, definitely not going back together though! That's a little beyond my skillset.

[@BudderKing4u]

if you planned on reusing the lash caps for any reason , you cant really mix them up, with not really adjustable hydraulic lifter setups, its best to match the worn cam lobes to their lifters and lash caps to ensure it still runs smoothly.

[@ColoredinLight]

These were never going to be reused. I just wanted to take the engine apart.

[@thekeeperob]

keepers! they are called keepers lol thank you so much for brutally dismembering this specific engine

[@ColoredinLight]

Yep man no prob glad to do it for you

[@bobdadruma]

You owned an electric impact wrench and you didn't use it to break the crankshaft pulley bolt loose?

[@ColoredinLight]

You know not all impact wrenches do everything, right?

[@sachinnaidoo9259]

Great video. Did you perhaps record the removal the engine? Would love to see that.

[@ColoredinLight]

I didn't take this engine out but there's a video of me taking my engine out multiple times in my 2.5 series

[@sachinnaidoo9259]

My NC1 has blown a head gasket on the original 2.0 MZR LF-VE motor. Any advice on the cylinder head removal without dismantling too much of the other components?

[@Sho-np2qz]

thank you very much this is amazing

[@Rot05]

There is something relaxing and intriguing about watching a disassembly video. Man + Machine = Bliss

[@ColoredinLight]

It was really nice to zone out and just disassemble

[@nunchako]

Is it too late for the piston contest? :P Excellent channel, I have an mx5 and learn from your projects. I would have learned to repair that engine. Greetings from Spain

[@coatingsplatingsjas1powder557]

How are you is this a mzr disi engine and what cars do they come in thank you

[@tylercassidy6310]

only video i could find of the MIATA 2.0 getting torn down, good work boos definitely gonna be on this channel more

[@lakessbm]

good thing you were protected from the corona virus inside your engine :)

[@davea1317]

Way to go man! Definitely interesting to watch so thanks for making it!

[@ColoredinLight]

Thanks!

[@diymx5908]

I like how you progressed from calling the bearings for the con rod ‘little metal pieces’ to calling the crank bearings ‘bearings’. We’ve all got to start somewhere. Good job for diving in and getting stuck in 👍

[@ColoredinLight]

Haha like I said, I'm not sure on the exact nomenclature but yeah learning is fun

[@Crotch_Goblin1]

they are little metal pieces-----....they are not fricking little PLASTIC pieces, is it?????
