Why Is the D17 The Worst D Series Ever Made? Blown Engine Teardown

To check out our parts inventory and parts cars please visit www.Importapart.com or email us at [e-mail] for part inquiries.
If this is the very first teardown you've found on this channel, here are some of my favorites:

Ford 6.8L 3V V10 • FORD 6.8L 3V V10 TEARD...
Dodge Viper V10 • This Dodge Viper V10 E...
Mercedes AMG V8 • Mercedes M156 6.2L AMG...
Today's subject is a very ruined 1.7L SOHC Vtec D17A2 from a 2001-2005 Honda Civic EX. This engine is also found in other Honda and Acura vehicles in other parts of the country.
This particular engine has over 200K miles which is pretty common for this generation. While it did look like this engine was maintained fairly well, something caused a catastrophic failure which led to this engine being on my stand. Lets tear it down to figure out what may have happened here.
Why am I doing this? I own a full service auto salvage yard in the Saint Louis Missouri area called Importapart. Part of our model includes buying core or bad engines and dismantling them to salvage the good parts from while recycling the rest. We do not rebuild engines, merely supply parts to those who do.
I hope you enjoyed this video, as always, I love all of the comments, feedback and even the criticism.
Catch you on the next one!

Lived the exact same scenario with my daughters 04' Civic, and you definitely hit all the points on the mark with this engine. Got 240K miles out of the old one with a head gasket done at 210K miles. She didn't check her oil and the oil pump/pan started to leak slightly, which lead to a shattered #4 rod. Luckily, about $200 got me a 160K mile shortblock from a PickNPull, pulled the 50lb block with my bare hands, resealed everything, dropped the new block in, swapped the old head on with 2 new intake valves and she's ready for another 200K miles.

I have an 02 civic that has been turned into a "farm car". It has been beat on so much, overheated a handful of times, and hits the limiter on the regular. I keep oil, and coolant in it, and haven't overheated it yet after fixing the fans. It runs so smoothly, so quietly, like a sowing machine. Ironically out of my 5 vehicles I have, this one has been the most reliable. Only ever "breaking" twice. It needed a starter, and the fuel pressure regulator fell off the pump which was fixed for free with a zip tie.

[@dougrobinson8602]

[@runningawayvagabond5876]

I drive a Civic and am a maintenance freak because of video's like this. And you're absolutely correct - no one checks their oil levels anymore which is a real head scratcher since all manufacturers are going with extended drain intervals. Much higher likelihood of burning off a bit of oil between changes. Personally do it on the 1st of the month every month so I don't forget. Because I change my oil so often my oil never darkens and Honda uses an orange tip on their dipsticks, I hope there is a special place in hell for whoever came up with that idea. Trying to read honey coloured oil on orange? Dumbest idea ever.

[@jake6483]

What oil do you use? Just out of curiosity

[@Slaktrax]

It's more to do with the soft tension piston rings they started using in the quest for lower internal friction. This is what causes oil consumption problems and they've made the rings more thin (narrower) which adds to the problem as well as narrower oil control rings too that gum up much more easily. But agreed, extended oil change intervals allow sludge to slowly bulid up inside the engine. When the oil is no longer clear and honey colored it needs to be changed.

[@CptSideSlider]

Oh good! I'm not the only one with hatred in my heart for the muppet who had the orange dipstick idea.

[@dougrobinson8602]

I'm pretty old. Let's just leave it at that. I worked at a gas station, and we always checked the oil on every car. For regular customers, we kept mental notes on oil levels, so we could often tell the customer if they were having oil consumption issues. Now that nearly everyone fuels themselves, I doubt many people ever check their oil. I make it a habit to check it every other tank, and a couple times a week on my BMW, because you just check oil level on the Idrive screen. Car manufacturers' oil change interval recommendations are a joke. Don't wait for the car to beg you for fresh oil. Just do it every 5,000 miles.

I think you nailed it. Good maintenance, but low oil level and high revs killed it. That piston looked like it was accidentally installed backwards, so It may be a case where this engine was rebuilt and reassembled improperly.

[@AB-nu5we]

Just knead some Raman into some JB Weld and that block hole is patched.

[@stephenkramme7063]

The reason for the disintegration of the lower timing belt cover and all that crud on the block in that area 10:48 is the worn oil pump housing o-ring. It is visible at 21:32 at about the eleven o'clock position. When that o-ring contracts from age it allows oil to exit, attracting all manner of road grime. It also lubricates the timing belt. This leak is often misdiagnosed as a leaking crank seal. This engine also requires a fair amount of patience and technique to remove all the air from the cooling system whenever the coolant is changed.

[@hdfxrs9121]

Oh man, I just remarked on that and then saw your comment. Yes, you are correct about that stupid little O-ring.

[@jfulton1795]

I have oil everywhere on that side, and I do believe it's from that seal. But at 180,000 miles I don't know if I should keep the OEM oil pump and just replace the seal or replace the whole pump. Any thoughts?

[@hdfxrs9121]

@@jfulton1795 Pump rarely goes bad. Just replace the O-ring. If you're close to when your timing belt is to be replaced, do it then. To replace that O-ring means a timing belt service and removing the oil pan and oil pump.

[@SPAZTICCYTOPLASM]

I think the low oil theory has some merit, but i've seen these engines fail first hand in the same ways or similar, i think it's a design flaw. I'm an engine shop in Toronto and i've seen my share of D series engines (usually guys who want them rebuilt and don't know the costs associated). In my opinion the issue with these engines is the rods. I've measured the rods on these and they're always ovaled out up and down even on lower mileage engines. These engines also have a lot of rod bearing failures and i think it's for the same reasons. These engines are a substantially under square design, that means the stroke is MUCH longer than the bore, under square designs are great for torque but the piston velocity puts a lot of stress revving on the rods, but these things have a redline of 7000 or so. The diffrence in bore to stroke's huge it's 75 mm × 94.4 mm (2.95 in × 3.72 in) that's a 1.26 stroke to bore ratio, again great for a high torque lower revving engine, but throw in the redline at 7k and it's not so great. Comparing it to other engines: 1zz-fe 79 mm × 91.5 mm (3.11 in × 3.60 in) under square but much closer ratio 1.15 and lower redline at 6500 B20: 84 mm × 89 mm (3.31 in × 3.50 in) under square but almost square at 1.06 ratio and lower redline 6800 R20 that replaced the D series: 81 mm × 96.9 mm (3.19 in × 3.81 in) ratio of 1.19 and redline 7100 I think -and this is an educated guess not really a tested thing- the D17s massively under square design puts a lot of stress on already very weak economy rods at high rpm and it's rev limiter is set way too high for what it should be, and it's oiling and clearances are just not able to cope. I think overtime and with RPM these rods like to deforms which means even if you have good oil pressure you have tight and open spots in the rods and a loss of total lubrication that's just based on measuring them, i don't think that's what happened here specifically but it maybe related. I honestly don't believe this engine was ran low on oil. The rod bearings on these engines are a common thing to go if they've seen RPMs and i think that's rod deformation related. Another thing specifically the rod bolts are known to be a weak point on these engines, and that's my guess for what happened here. I've personally seen these guys launch rods at parking lot meets where someone thinks their 1.7 and drilled muffler sounds good. The way that rod bolt stretched into a bullet is fairly common, and typically (if someone wants these done properly) you gotta get the ARP replacements and resize the rods (not generally done or worthwhile).

[@xddstudiosbywr3cked845]

so, if one wants to run these at high rpm, they should get a different engine instead? or is there a way to make them withstand high rpm?

[@dougrobinson8602]

Hmmm. I didn't know Honda had cylinder deactivation in the early 2000's. Very impressive!

[@liver.flush.maestro]

One thing that comes to mind about the piston turning is that because of VTEC, some valves don't open fully and thus create asymmetry, and perhaps the piston hit an open valve on only one side, and since the valves are at an angle, they bend and sent the piston in a spin... Also if you look carefully at 16:42 there is only one valve bent, the 3 others seat correctly, supporting this theory 🙂

[@Stevethemiller]

Do you think that would break the connecting rod though? I think it would damage the valve and top of piston yes. But twist a rod and turn the piston 180 degrees on the dot is a little suspicious and there's not a lot of damage to the head. Could it have been assembled wrong? Idk much on v tech Hondas. Just curious

[@mtbridingog9083]

A bent valve won’t cause a piston to spin in the bore .. a broken valve maybe but not a bent valve .. it’s not possible unless the connecting rod was already separated from the piston wrist pin .

[@Stevethemiller]

@@mtbridingog9083 exactly man! I think the piston and rod where assembled incorrectly and put in the block backwards it explains why just that rod gave way and that it was almost perfectly 180° the opposite direction from the rest. It'll still run with a back ward piston! The question is for how long..?? Or the rod broke first which had the right amount force to rotate the piston when the two peaces hit each other again but the hole in the block says other whys cause that rod left the building probably ended up a couple counties down yonder. Over there 👉👆👇👈

[@PistonAvatarGuy]

They all open, it's just that one intake valve opens more than the other when the engine isn't running on the mid lobe (or the larger lobe, in this case). If one valve remained closed, fuel would pool in the port.

[@crazzywolfie]

got a 04 civic and am constantly making sure the coolant is topped up on it since replacing the head gasket would likely cost more than the vehicle is worth. best thing i have done is buy one of them radiator caps with the lever to release the pressure. if i release the pressure while the engine is hot when i am done driving it generally sucks most of the coolant back into the engine. it is definitely much easier than pumping the coolant from the over flow into a jug just so i can put it back in the rad again which is what i had been doing for a bit.

[@The513Warning]

I remember those days lol. Before I did my head gasket, I had a whole routine of taking a transfer pump and hand pumping the coolant from the reservoir back into the radiator. I recommend replacing the gasket. You'll get your money's worth out the car in the long run. What we consider "worth it" is different to every person, and it's not always monetary. Even if you do it yourself, it's not a difficult job and these engines are great for learning to work on cars.

[@crazzywolfie]

@@The513Warning it also needs a bunch of other stuff including a wheel bearing, lower control arm bushing, and a alternator if i attempt to remove or adjust the belt since the bolts will likely snap off inside it since i live in the last of salt and sand. the head gasket the honda guys recommend is $100 on its own and if you ad in the cost of all the other parts you should replace it is at least $1000 in parts. like i said i have found the radiator cap that you can release the pressure has helped a lot. been driving the vehicle for nearly 3 years with a bad head gasket.

[@The513Warning]

@@crazzywolfie You can drive with a ripped lower control arm bushing just fine. Both of mine are completely ripped. They're on my list of things to replace, but they're not urgent. Worst case scenario, you get some steering wheel drift or shaking when braking. Honda sells the compliance bushings separately for $25. The challenge would be to get the old one out. Wheel bearings are also pretty cheap. You can get front KOYO bearings (an OEM supplier for Honda and a few Japanese cars) from NAPA for about $50. Take the spindle off and have a machine shop press it in for you for cheap. The rear bearings are stupid easy to replace too. I believe that the adjuster (butterfly bolt) and lock bolt for the alternator and A/C belt are aluminum. I live in an area where we get a lot of salt and even at the junkyard, those particular bolts are never rusty. It'll get kinda hard to remove due to different metals and constantly heating and cooling, but it usually comes out fine.

[@The3chordwonder]

I have to wonder with how clean it was and with no scoring or anything, if the engine wasn't rebuilt, but the assembler put in #2 backwards from the start. I don't know Honda engines enough, but for others, it would affect the rod being too loose on either the front or back, and the other direction being clamped too tight. And that would explain the heat build up in just one crank throw. If not that, then a single-cylinder detonation comes to mind, but I still don't think it could spin a piston.

Thanks Eric for something new and interesting again on the channel. I personally like it when you try different engines (if I'm honest I'm a bit bored of seeing GM V8's in particular). I'd love to see something left of field from a different brand on the channel. Say something from Peugeot/Citroën, Renault, Mitsubishi, Fiat, Alfa Romeo, Landrover (older pre-Ford stuff), Suzuki, Volvo etc. Anything totally new is what keeps me coming back more than anything. Of course it's always entertaining with your witty quips. Keep it up Eric

[@mahcooharper9577]

Another great video, thankyou Eric. I've been up for 25 hours but just saw that you uploaded your weekly teardown and stayed up half an hour to watch. Worth it as usual. Never seen a piston do a 180 in the bore. Good effort! Keep it up :)

[@davidg3944]

I just saw the video title again and FINALLY got the joke! I can't believe it took two weeks, especially as I've worked in Astrophysics tech support. Argh...

[@mikeybhoutex]

I had to comment on the thumbnail because that's awesome: Supermassive Block Hole indeed. :D

[@94XJ]

I really like that crankcase ventilation! Who needs all those fancy hoses and stuff when you can just put a hole in the block? Brilliant.

[@Mittencarpentry]

Always enjoy a good Sandler reference.

[@kars4me2]

Awesome thanks for sharing from Fulton Mississippi

[@user-kk8uc9st5y]

The best thing was the gorgeous E34 at the end of the video. Love it.

[@mikikum1]

Man, that E34 behind you is the best part of the video 😍😍😍

[@Madpegasusmax]

Once again ,cool video, amazed by the picasso rod ,quite impressive as élongation . Keep up the good job... l’m curious for the suite on the cl55 injection system ;)

[@FeralPreacher]

Excellent video. Total description and step by step tear down. Should be able to sell the block at premium price with the added inspection port. Right? Always a pleasure to get your videos. Thanks for sharing.

[@paulburns73]

I like your videos because you know what you are looking at

[@randallmunson9909]

The crank journal lost it's love for it's connection rod and set it free ! 😂

Happy Gilmore really knows his way round an engine.

[@lizkrinsky5209]

Gotta pause and head to work. Crocheting during an overnight hospice shift and watching engine autopsies. I have a lot of different interests lol.

[@mikek5298]

Strange. Just strange.

[@monomille1]

Loved the Halloween creaking door sounds the head bolts made!

[@pontymighton6300]

This astrophysics joke on a preview image got me rolling! My man, good sense of humour. All the best!

[@evanholman4876]

a youtube channel that is super chill, makes me giggle, has a host whos voice is soothing enough to fall asleep to AND helps me learn more about cars? this is the perfect youtube channel

[@666cemetaryslut]

I've tried to fall asleep to this channel but the sped up impact gun montages always wake me up.

[@chowchow2386]

My '04 Civic had that engine in it, I got near 400,000km on it. Only reason i scrapped car was due to a failed transmission (2nd time) and main wiring harness was developing shorts. Engine still ran great, started on 1st turn every time. Even had decent compression still, about 110 each cylinder.

At 2:51 "Needs to be machined condition...." You mean, "pristine, needs to be machined condition...."

[@PistonAvatarGuy]

It was definitely time for Honda to retire the D-series by the time the D17 came out, but my ex had one that I maintained from 100k miles to 240k+ miles, and it showed absolutely no sign of being worn out. It didn't burn oil, but it did have a coolant leak at the back of the head, I suspect a new gasket at the water passage (as Honda calls it) would have solved the issue, but we split up and it was no longer my problem.

[@douglasmaier3066]

Good I've been going through carnage withdrawals!

[@billb3444]

I rebuilt my daughter 05 and when removing the head ended up with two rubber O rings! Looked everywhere, even bought old dealer parts books and very little information. Only place they could have come from was either side of the oil restrictor in between the block and head. The O rings are different sizes so put one either side of the removable restrictor, they fitted, and put it all back together. Engine still running 10k later. Great video. Thanks

[@billbaber6653]

Good show kid better than weekend football thanks.

[@alanbradford3130]

I don't have any experience with the previous gen (2000 and older) engines, but my experience with the D series engine has been good, as long as you aren't looking for any kind of performance. I fixed up one of these cars as a COVID project and gained respect after doing a lot of work on the car. The engine was reliable despite being mistreated by its previous owner. even in with over 200k+ miles the engine ran flawlessly. I think these are good engines (as long as you aren't looking for any performance) will last a long time and be reliable. Maybe the pre 2001 civics had better engines, but when compared to other cars they are still very good.

[@markr.1984]

Install a turbo kit, there's your performance. Just kidding....😆

[@alanbradford3130]

@@markr.1984 - from what I understand, you cannot "tune" a D series engine, and putting a turbo on the engine would not get much of a horsepower increase.

[@punkhead4312]

Never get tired of the "waterpump throw."😂😂😂

[@PardnerCLUTCH]

3:05 I can see the CL ad now... "ran when parked!"

[@rickbaker4571]

Some well placed JBWeld, and KABOOM!! Good as new!!

[@localcrew]

I agree. Low oil then instantaneous starvation. Really surprised that only the one journal was smoked. I got nothing on the 180.

[@dudemelonhed8508]

I love this, all of this. Thank you Eric for another great teardown.

[@nagyzoo85]

29:50 What a beauty in the background!

[@paulburns73]

Also you teach us about every issue that you see on all the motors you tear down

[@joshuac837]

Darn! Should've done this teardown a month ago, I would've totally bought that PCV breather from you! My D17 at home has one heck of a vacuum leak from a rusty breather
