I've been tearing down engines on camera for 2 and a half years! Search my channel to see what I've torn down.
Today I tear down a 2.0L Ecoboost from a 2015 Focus ST. This is the same 2.0L Found in the Fusion, Edge, Explorer Etc. I found this engine in the core area of a local salvage yard with some other cores I bought. During the teardown, I discover heat tabs placed on the engine. Heat tabs are glued to an engine by salvage yards and rebuilders. If the engine reaches a certain temperature, character of an overheat condition, the center will melt out. The existence of these tabs mean that this engine wasn't a core, but a sold engine that was returned. Why was it returned? We tear the entire thing down to find out.
Why on Mercury am I doing these teardowns? I own and run a full service auto salvage business in the Saint Louis area called Importapart. Part of our model is buying blown, core and unwanted engines and dismantling them to resell the good, usable parts. We do not rebuild engines, we merely supply parts to those who do.
I really hope you enjoyed this teardown. As always, I love all of the comments, feedback, and even the criticism. Catch you on the next one!

The spark plug wires bouncing up from pressure was inexplicably funny to me
Same here. rofl
Me too!
I thought it was time to play Whack-a-Mole.
Coils, no spark plug wires on these. They are coil on plug.
Yes, I found that amusing too.
As a 34 year retired auto mechanic, shop foreman, etc, If i lived close to Eric, I don t about 700 miles away, I would love to volunteer to help him do these tear downs. I will be there one day cause visiting Eric s shop is on my bucket list. I never miss a video
Yeah, me too. I'd sweep the floors and make great food and get the beers.
Same
A Live Show.... 😮
I'm all in !
Thanks, but that gets creepy when strangers want to show up and be pals
@@mitchhedberg4415
We’re all car lovers, aren’t we?
@@Conservator.without a doubt
I think I see what was going on here. The yard sold the customer a perfectly good engine, but customer had driveability issues that they falsely attributed to engine mechanical problems, so they returned it. I'll bet the customer bought another engine after that, and had the same issues.
May missdiagnosed..Turbo failure?
Maybe electronic issues?
Customers are quick to blame a fault on the last thing that changed. The term "it was working before" is one I've heard all too often. My bet though is on the turbo. I've heard stories about turbos on these engines in the ST.
@@keenanmolver9689 Maybe it was the turbo. Customers are quick to replace things instead of performing accurate troubleshooting techniques
Seen it before, dude replaced an engine and had exact same issue. Catalytic converter was plugged lol
I'm going to say it's the carboned up vales.. it probably was causing a misfire, as well as the staining you see from it possibly being lean.. great video as always!
Yep you beat me to it! I guarantee you that's all that was wrong with this engine probably cylinder two and three weren't making good compression due to carbon and somebody just said the hell with it swap the whole engine instead of fixing it
Yep I have one of these in a 22 Maverick. They are known to carbon up the seats of the valves, been told it's the number one problem. I installed two oil catch cans on the PVC system to help with this issue. I know when he looked in the ports it did not look good, should have removed the valves.
@@richs7362 You also have to consider that its direct infection, and what kind of codes that will bring up while in a starting sequence. Couldn't be good .
Ford, circled the problem
Mine were worse on my 2L EB and I had no misfires. It is possible though.
Very educational, shows what happens when an engine gets frequent oil changes, man was that engine was very clean! Thanks for sharing Eric!
And regular BK engine flushes would result in much cleaner rings and lands.
yes,,but it was driven like a horse & cart,,not a fkn race engine, like it should of been, direct injection is the problem.. carbon.. de carbon that engine, last forever.. there basically bullitt proof if DRIVEN.
That engine has the coveted "Whack-A-Mole" option! Seriously, I'm with you on that keyless crankshaft - I think they're saving a dollar by eliminating the keying operation - and gaining several dollars by selling those magic washers. That little pep talk at the end reminded me of a painful lesson I learned as young man : I bought a rim from my local salvage yard, and took it to a tire shop to have a tire mounted on it. The tire shop had the foresight to check the rim, instead of just putting the tire on and sending me on my way - and the rim was warped. So I took the rim back to the salvage yard and they gave me another. This time, I mounted the rim on my Jeep and checked it before going to the tire shop with it - and it was also warped! I went back to the salvage yard for another, and asked them if they had a way of checking them. The gentleman said "We sure do - we sell them to someone like you, and if they bring it back, we know it's bad". Ouch! So glad to know you don't do business like that - and I really enjoy the videos!
Whew! Good to know I'm not the only one with the Whack-a-Mole thought...
I think Eric is wrong in his statement about yards caring about what they sell. The mantra in that biz seems to be "you pays yer munnys and it's yours".
Great story, a little bit sad but it made me smile nonetheless. Tx!
It's called having integrity, or pride in your work. Sadly it is not the norm today. Find the good guys out there and stick with them! Also spread the word about them!

💯
Gummed up valves caused low compression and/or leak down. That is why the plugs were out.
thats what I think
valves looked horrid
these do not have hydraulic lifters, the buckets come in several sizes and are matched for a fixed gap. This is fine for 50-60k miles, then it needs adjustment. To do so, the shop has to remove the head, measure the gap, order specific buckets, remove the camshafts, swap the buckets, put the head back together, check the gap (and prey they got it right...), bolt the engine back together.
This costs over $1k to do, takes about 3 days (waiting on parts) during which the shop has a non-driveable car taking up space, so it's rarely done when it's supposed to and the valves and seats get beat to death from the excessive gap, causing compression loss. All because Ford was a cheap c*nt.
@@AKAtheA Jaguar got away with this scheme for 40 years on the XK engine. But it was not meant to be a mass-market engine for the riff-raff who couldn't afford the shop charge and a back-up vehicle. In the design phase some boy wonder must have convinced somebody that through a miraculous new process, wear in the camshaft, bucket, valve, and seat would be eliminated.
It is sad to see so many of the new engines, with so many wonderfully designed and built aspects, have one or two fatal flaws. This is the nature of piling-on so many innovations into one new product: all it takes is one mistake and all that good work goes for nothing. EV buyers should take note and tread cautiously.
@@tomscott1159 Honda (bikes) and Toyota (the legendary 2JZ) use this successfully for years, but in applications where it makes sense - like revving the engine to the moon and back. It's kinda' retarded on an econobox that redlines before 7k RPM, the customer literally gets no benefit here. Whatever was saved on a set of rocker arms and lifters (heck, ditch the lifters if you must, but give it adjustment screws) is eaten by the adjustment procedure...
The key thing is just them saving money by not machining the cranks and the pulleys for a key. I've been a machinist for many years and key ways usually have a .001 tolerance on the width and key and the location is also usually a plus or minus 1 degree tolerance. The current machining rate (my shop) is about $145 an hour so if they can save that for the millions of cranks they produce, that;s a huge amount saved.
I worked for a car manufacturer as a trainer and field support. When theb keyways went away in the early 90s the info was that tolerance drift and market emissions adaptability were why gears quit being keyed. The cam setup and crank positioning was blueprinted like hotrodders have done for ages. If deck height or cylinder deck to cam centers varied then it was handled. If turbo and non-turbo engines had two ideal cam setups then the robots and the dealer service tools handled it.
Your hitting the sweet spot.
Isn't slotting one of the more expensive processes? Like, the joke I picked up is that the best way to make money with a slotting machine is to not buy one.
Wow 2 years since the last 2.0? Feels like 10 months ago. Time sure flies when you work hard! Keep it up.
I rented a 2018 Focus ST in Germany and drove several Alpine passes with it, 2 laps on the Nurburgring, and cruised at 140+ mph on the Autobahn. Great car and great engine/trans combo. Even the Recaro seats were excellent (if you're under 200 lbs).
They are good cars but the engine does have its limits. They can't be pushed too much as the pistons and rods are only safe for around 300-310hp (at least for uk build focus st250). However, the block is pretty strong.
I weigh 240 an the seats are fine for me mine was great for 5 years I gave it to my son for his 16th bday an bought a type r
I in no way feel shorted if your teardown reveals an operable engine. It was an interesting video, Eric.
Another great teardown, as always. There's just something fascinating about seeing how these engines come together, or sometimes violently fall apart
Always enjoy watching your teardown videos. Keep the content coming. Hope all turns out well with the Porsche!
Still absolutely loving your tear down videos and your often successful attempts to get those lost cause engines to run. Thank you.
You always provide good info on engines that have not much feedback.
I love your videos they are relaxing and informational keep em coming bud love all that you do
Will leak-downs make their way into teardown videos before they come apart after this experience? Might add a few minutes to each video, but it would definitely help explain the situation too.
I suppose it may on engines with no obvious problems
@@I_Do_Cars the fact that 2 and 3 were not making enough compression to pop the coils out was concerning. wonder if the customer did a compression test and found that 2 and 3 were low. if the rods are compressed even just a bit, or even a bit bent, it would lead to poor running because of lower compression.
@@chubbysumo2230- yep. Could have idled just a tiny bit rough due to even the carbon build up on the valves and was declared as “not good enough” and pulled back out. 🤷🏻♂️
@@I_Do_Cars As others have said, the coils not popping on some cylinders could be due to low compression, but could just be you didn't crank it at the same speed on those cylinders. Stuck rings looks to be the most likely cause. The engine otherwise looked barely bed in. Bearings initially look bad then improve in the first 100 hours.
@@I_Do_Cars old bikes, 1930,s had cone clamping.& machines,, easier manufacturing, never had any probs with them. &, id say harleys still use it, cos there pre historic relics of bikes.. i have a focus, tdi. 2.0. goes like a cut cat..5 lt 100. 08..ausie..
Mad respect Eric. I've worked at yards that sold engines that we were never able to test. You have integrity and standards. Please keep being you
Good morning as always, thank you for sharing this with us as always Eric. I will have to look at the website to see if you have any of the stuff that I need. Great Sunday morning and enjoy your day today. Thank you for your time, help, and work.
Eric,
Great video as always! You have a great channel - thank you!
Paul (in MA)
Oh yeah an engine in that condition could most definitely be rebuilt. I was not expecting a teardown like this. What also made my day was the high pitched voice. Not making fun but the editing with that was great. Great job as always Eric.
Dude you're my favorite person who takes engine's apart just to find out why it's there, I'm sure other people do it but they are not as entertaining, I'll say I have a 2.3 version of that engine and I'm glad to hear all of it's shortcomings and why it's bad, I'm glad to know What to look for, you tearing down engine's shows us what to look for and how to fix it before it blows up
2014 ST owner! Saw your last video about this engine, one of the most clean tear downs on the channel
Great to see a 2.0 teardown. I'm hoping for a 2.0 Ecotec Turbo Chevrolet teardown. I always look forward to your Saturday night videos!
the industry you are in looks like fun, that eco boost motor looked ok, thanks for the vid sir
20 years as an OEM Ford tech here, and I enjoy all of your video's, and have even learned a few things off of a few of them! Spot on with the outro about the industry, I see so many mis-diagnosed things come in for repair with sometimes a few thousand dollars of parts store coils/PCM's/ect hung on them over what usually turns out to be a few hundred dollar fix, it's sometimes unbelievable. Proper diagnosis is the most critical part of any repair as you have stated, especially with the complexity of modern vehicles.
Channel is very informative and entertaining. You seem like one of those rare business owners who actually give a shit about its customers, very refreshing to see.
It never sucks! Your videos are always good.
Video is good product is the problem
Thanks for the video.
WOW that van, really need a video about how it got that way.
I very much like that this is a family friendly channel. I can refer kids to this channel without hesitation. Thanks for leaving the machismo behind. Your channel is great! Thank you very much - it takes a lot to make a good video, let alone a great one!
Listening to your last comments on this video is exactly why i like watching your channel..and i like Listening to you
Big turbo on my ST pushing 70k miles now 👍🏻 love this car so easy to work on!!
Another great teardown video, thanks for sharing 👍.
Eric, I think you forgot to check for disconnecting rods. I always look forward for that test.
I was thinking the same thing,
He did manually try to move the big end of the rods though. 18:00
Your other 2.0 was what introduced me to your channel. I had just bought a fiesta st and my pops sent me the 2.0 teardown thinking it was what's in the fiesta. Still waiting for that 1.6l ecoboost teardown. I just got a big turbo for mine so if/when it blows up, I think I'd like to send it your way haha.
I think the first clue was when the coils on cyl 2 and 3 didn't pop up like 1 and 4 did.... maybe valves not seating properly as others have stated...
Exactly my thoughts after seeing that demonstration at the beginning (and then the lack of obvious damage otherwise later on to offer an alternative cause of loss of compression on 2+3)
The only other option I see is incorrect clamping force on the head in those areas with the less tight head bolts (located around the area between 2 and 3), assuming the mating surfaces and gaskets were all in spec.
The engine looked well engineered and maintained.
Eric, congratulations on getting a bunch of serviceable, sellable parts. I hope you turn a profit on this.
Dam! That van had a bad day, I hope no one was in it when the side was removed.
Great video as usual, thanks for sharing with us!
Issue i had with mine was the head cracking. Ford Perfromance states manufactering decfect. They had to do an xray to find where it was. Common symptom is misfire MIL that is inexplicable to solve. Once you get a good one though it went 150k miles.
I got up and poured a glass of Bourbon while i let a 2:00 ad for Pillow Cube play in its entirety.
Showing love, friend!
My expectations of Ford are very low and then to have a seemingly good engine torn apart was rather shocking. Nice to see someone actually did oil changes. The engine was super clean.
These are great little engines. Very reliable for the power output.
Ford makes some of the most durable engines around…
@@newfie-dean5803just if you neglect the transmission in the slightest bit. Or look at if funny. Sad things happen
Keep up the great work Eric been away from the channel with family issues first video in a few weeks safe to say I've got a healthy back log off videos to catch up on. Keep up the good work sounds sad but your videos are one off the only things keeping me going at the moment
Keep your head up! Thanks for the comment buddy
Best looking engine on this channel so far. It seemed fine.
Another great tear down! 👍🏻👍🏻👍🏻
Great video. Love your new studio (the van)!!
Good job Eric, thank you
Love all your videos, there's always something new to learn.
Is there a story about what happened to the contractor's van? It looks like Thor's can opener was taken to the right side.
Dangerously close to the 2.3 ecoboost from the s550 teardown I’ll keep beggin for it lol. Love the content bro
Love it Eric!!
Thank you for posting this very interesting video!
I appreciate this video, even though the engine wasn't broken. I own a 2014 Focus ST, and this video was really helpful for me. The internals look far more stout than I was expecting, so I guess I can feel good about leaning on mine a little harder in future. I do wish that they had port injection to limit in the inlet valve fouling, aside from that I'm really pleased wit mine, it does everything advertised on the outside of the tin.
Spray some Seafoam past the air filter and it'll help clean that stuff off
@@Ar0d The ideal thing is to get it into port if possible. 69000 km on mine, no stutter yet, but it must be coming 🤔
Iv owed a Mazda 6i with the 2.3 auto for over 6yrs with roughly 185k. It’s a great work car. Zero driveline issues. Just bought a 13 ST with 70k. These two motor blocks being so similar gives me a lot of confidence. Thank you for the info.
Very good. Thank you men!
I could care less if the engine being torn down is bad or good. A good engine is better for Eric, so as long as I get to watch a teardown I'm happy.
Im gonna go with low compression, hence the difference in tightness of the head bolts which probably caused vibration issues. I notice a bit of skirt wear on a few of the pistons as you were examining them which would explain the minor wear in the crank journals. I would say who ever put this engine back together did a great job except they probably forgot or didn't do a great job of calibrating their torque wrench when tightening the head bolts. It's the minor details that make engine building so difficult to reproduce the same reliability of the oems. Probably ran amazing for the first 20 or 30k.
Love the channel! It's greatly appreciated
thanks, Eric. 👍
Absolutely love that vid - sometimes engines are just perfectly fine. I was strongly looking to buy one of those Focus STs when they were new, great looking super fun car. But the ergo seemed set up for drivers significantly shorter than me, just couldn't get comfortable and ended up with a WRX instead.
I'm 6'2 and bought one brand new in '13. Loved it, I had plenty of room.
Aside from the keyless crank, this seems like a well designed little engine that's easy to work on.
Stopped the video at 20:30 to post this and will finish it in a minute but I have to say that from what I've seen so far is that there was probably a fuel delivery problem causing the carbon build up around the ring lands which if true, it was probably smoking through the exhaust system making the vehicle owner think that the motor was bad.
Unfortunate to see a good $3,000+ used motor go to waste but then again, you could freshen it up with new rings, bearings and polishing and maybe get $4k out of it.
Outstanding videos BTW. Thank you! 😎
I have a Duratech 2.0 in a 2005 Ford Focus and I have 138,000 miles on it. I have changed the valve cover and gasket, plugs, and coils. I noticed, when I was in there, that I will have to change the timing chain in the next 40-50,000 miles and it seems to be a pretty simple job. It uses the same "diamond" washer on the crank so you have to have a tool to keep the crank in the correct position and a bar on the head to keep the cams in place. Other than it being a tight fit, doing it in the car, it is really a simple job. I have no complaints with this engine. It is much better than the new "wet belt" system Ford is using now.
Awesome video, very detailed, however what you referred to as the Cruise Control System (hose assembly) is actually the Vapor Canister Purge Valve Assembly, which when fail will push a P1450 Code
Anticlimactic but equally entertaining. I second the motion for pre-tear down leak testing. It would also be neat to see the build and use a run test stand. Old school wasn't challenging before ecu but Im sure there's something semi universal that is out there, yeah I don't ask for much.....
I had an fiesta st engine replaced after a blown head gasket, thankfully they did it for free under a recall. this video made me wonder what they did with my old engine because I’m guessing it was still in pretty good shape
18:10 was waiting for u to tap the tops of the pistons w ur mallet like u usually do before proceding especially since u noted #2 and 3 seemed tight at the top of the stroke.
Good evening Eric. I have this engine in my Lincoln MKC 2016. That Van looks like the one someone Said Ray was in a wreck with early this week 😆
Nice clean inside lots of good parts to sell for once it's gotta be a win win for once ....
I would love to see a newer model 6.6 Duramax, or especially a LBZ engine! If I get some money, I will order a LBZ from you. Otherwise, I appreciate your video's, and you do a great job with them. I always look forward to seeing them each week! Thanks Eric!
Valve timing with vvt engines is generally "close enough" as it floats around. So long as its in a safe range
that van looks exactly like my work van down to the welder mount! but more ventilated :) crazy
This is same engine with my 2015 Ford Explorer ecoboost. With regular change oil and ATF. So far no issues and drives like a dream.
I have a NA 2012 2.0, my valve train looked very similar to this. For some reason you do regular oil changes and those valve trains look almost new even after 90K miles.
Love your videos man been watching you for a while. Are you ever going to put out any Merch?
Thank you for another video 🙏🏼 I really enjoy your video wich also give me knowledge. I wonder if you can make a video about the volkswagen 2.5 from mk5-mk6 gen there is no video online. It would be so nice to see how its done 🙏🏼
Another great video! Entertaining and informative... 😁
Thanks for another great video Eric! Could we get a VW 2.0 CR TDI on the engine stand? Particularly engine code CJAA if you come across one.
I think your motor there has major compression issues..Great vid!
I know these engines need a certain spec of oil to reduce these problems, i am in the uk and have a 2012 focus st having some problems with code for catalyst below efficiency, strangest thing is when i was attempting to change the catalyst and had to abandon doing it and tighten everything back up including the flange clamp on the turbo to exhaust connection the problem stopped!
Another fun weekend teardown. Looked awful clean
Would have liked to see the head, valves on the combustion side tell a tail. Color and pattern will indicate health.
Another educational disassembly, thanks for doing these vids. I find it good for my Petrol Soul.
Engine looked great.
Just short of 250k miles on mine.
If you are having misfire and stalling issues at idle, check the fuel tank purge solenoid; they fail open and allow fuel vapors to be sucked into the engine at idle which is overwhelming. Not an issue under boost, but a big issue at idle. Dirty intake valves don't help. I have had two solenoids fail in 11 years so far on the same vehicle (ford parts, not aftermarket).
These engines tuned with no key can usual withstand up to 500whp before the timing can slip. Those friction washers put in some crazy work. It seems some auto manufacturers believe keyed cranks can lead to being a weak or stress point of failure for the crank there. That's what I've heard but not sure its true for the keyed crank.
Hey Eric I own a 2014 Ford Focus SE/ST am been working on it to convert it to an ST about a year I swapped the factory 1.8L to the 2.0L for more pAwer (power) 😅😂 I did used the ford warranty to do this work but to be honest this engines are good for this generation
i have a 2014 fusion with the vel 2.0 engine... 173000 miles on it.. change the oil with full syn every 6-7000 miles..put in 6 quarts and get back almost all of it. .minus a oz or two.. has a tune on it est power it about 280-285.. very quick and in cruise at 70 mph..i get 34/35 mpg.. here in the flat road os sacrament.. but can easily crest donner summit at 90 mph.. to go fly fishing.. the car and this engine is great.. never o issue from new
Honestly, the engine pressure pushing the coils out and sucking them back in just after is inexplicably funny to me. Plus also the way you said "crack the cam caps loose" in this video made me just fukin lose it that's how hilarious it was haha. Gotta love the good ol' humor of missaying things intentionally in silly ways.
I love that you commented on the non keyed crank. My opinion…. Anyone who has worked on a fusion, or any other modern car without the use of a two post lift will often pull the crank pulley to make room to pull the engine away from the transmission and out the top. I would assume that that was done on this engine. So, the timing was enough off that the engine ran poorly, or not at all, but not far enough off that pistons dusted the valves. It happens on these engines. I would encourage any backyard mechanic to purchase a book or subscription to a reputable repair site before attacking a project of this scope. Unfortunately, if this is the case, the seller ended up taking the financial hit for a beginners’ mistake.
Whack a Mole!! You are a good and honest man.
Hey man love your videos thumbs up an all. Any chance can you find a 2.5l inline 4 from a Jeep tj? I just bought a 97 tj for my sons first ride and if life to see the engine torn down. Thank you I advance and keep up the awesome work!
Reverse Whack-A-Mole, very nice! Oh, scared me with the Screwdriver in the chain of the oil-pump a bit.
Eric
I might be a bit new to this channel. I am from South Africa an my name is Jan. It is fun to watch and very interesting. It makes you feel that you can fix anything yourself, you make it look so easy. I most recently watch your video on the Volvo 70 R. What a SCORE!
The reason I am writing you back on this video is once again, you show the carbon buildup in the intake port of a direct injection engine. Why does that happen? Most diesel engines are direct injection and why would the carbon bild up in the intake port so much? What causes it to do that and obviously you don't approve and neither do I.
Fortunately I drive an ordinary single cab Isuzu pick up KB250 2016 with the Gen 6, 4J engine in it. It seems that I am lucky enough to have port injection as the injectors are to one side outside the valve cover on the intake manifold side. Best Pick up ever. No fuss, relaible and hard working.
If you have done an explanation on one of your videos I missed, please send me the link below.

I have been trying to find a 2.3 crank for my 2.0 focus st but they are damn near impossible to find here in Australia, I have always loved the Ecoboost engines but it's a shame they have now made the later ones with a full open deck.
The Best combination is the earlier 2.0 block with the closed deck fitted with the 2.3 crank and rods which one day I'm hoping to convert mine to a 2.3.
Edit - another reason for the non keyed crank is they can be stronger as well, usually when a crank fails through the nose it usually fails at the key way location however that's usually only an issue on cranks with skinny long noses or when they are subjected to high loads such as driving a supercharger or extremely high rpm where harmonics try and rattle everything to pieces.
I used to work at a place that rebuilt parts and engines and I can tell you that we got a lot of returns of parts that tested good on the test stands. Maybe incompetence or maybe a little bit of fraud going on? We got a lot of good alternators back as defective. We also bought cores that were almost new and we loved those. Just about all the parts we good and reusable, though we put new brushes and bearings in everything.
I like Eric holding the chain saying "Yes Yes" and you can almost hear the dollar signs
Were the plug threads ever checked? Just wondering with them missing. Another great video.
In the Mazdaspeed community I've seen a lot of situations when people replaced all timing parts and even rebuilt engines because of accessories side poor maintenance, AC compressor pulleys and so on. It may be one of those cases with this engine as well.
Always great, this was interesting - mystery suspense - I think it was a good engine 🤞🤞🤞
As demonstrated in the closing scene, with the proper amount of force; everything comes apart.
Enjoyed this very much. There's a lot to learn in a damaged engine teardown, and there's a lot to learn in a good engine teardown. Both work for me.
Hey, it's worth mentioning that from 2017 to 2019 a different block was used in fusion, escape and edge. 2.0 in the ST was always closed deck, while from 2017 in the models mentioned, Ford used open deck design and instead of improving cooling, they caused problems with head gasket failures (mostly between cyl 1 and 2) and mentioned cracking of the block.
when guys do big power rs builds they use this block for the strength. mine is stroked to 2.3 and forged…
The 2015 Edge was the first to use the 2nd generation, open deck design.
Wow, great way to check relative compression, take the plugs out, stick the coils back in and spin it see how high they jump! Great!
