I am totally and completely D17 ignorant.

Looking at a 2003 Civic that is D17 powered...I'm actually looking at
it as a project to drive for the winter and then sell in the spring.

Do the D17's have any common problems?
Shitty oil passages leading to rod knock? Consuming oil like F23's?
Blowing up if you tap on the head with a wrench? Some great engineering idea gone wrong?

This Civic's body looks to be in pretty good shape for Michigan. Really wish they'd switch to beet juice and get rid of salt completely.

I've done a lot of head gaskets on those engines, from an incoming customer perspective. They don't seem to tolerate any amount of overheating or hot spots. The common failure root cause of the HG's appeared to be from people just not monitoring their coolant overflow tank level and letting it run dry over a long period of time, which will cause air to enter the system over a longer period. You will know the HG blew because the rad end tank (usually the top one) will explode/rapidly disassemble due to over pressure. It's a scary unexpected sound when they go.

Timing belt tensioner failure. Honda makes an updated timing belt tensioner bolt for this engine. The original protrudes past the tensioner pulley like barely more than 1/4 inch, leaving hardly any threads to work to retain the tensioner against the block. Seen many of these cars come in on a rollback with a no start symptom because the timing belt tensioner bolt threads gave way and the tensioner fell in the cover. To fix, you have to drop the left side of the engine low enough so that you can get a drill bit flush with the tensioner hole, drill it out and helicoil it, then new timing belt/waterpump/component kit with a longer grade 10.9 bolt that protrudes past the tensioner at least an inch to ensure a secure fasten to the block.

Thanks for the responses. Seriously. More details than I even expected. I appreciate it.

And Transzex, The roads here have seemed to buckle more than before. I swear to God, it's like having speedbumps on Pennsylvania, Eureka, Northline, Goddard. So knock that 30k down to 15k. Once I started riding on coilovers, it got way worse.

Even over a decade ago TimtheStick had airbags on his del Sol because of the bumps as "Pops" (RIP) had severe back issues. He could also raise the car WAY up so Pops could get in easier.

I miss those days in Taylortucky....

Ive been away from DSO and lookie here, another d17 potential.


First of all, check the alternator mounting. DOES NOT MATTER if belts are not making noise.

My loose alternator killed an ecu with the voltage spikes from occasionally loosing the most important ground of all, alternator to engine/chassis.

Same alternator, but I just killed a SECOND ecu. So Im not fixing it until I have a new denso or mitsu alternator. Stay away from remans for the 7th gen civics.


Front bushings are capabale of lasting far beyond 15k miles on shitty roads.

You should be able to squeak out at least 25-30k miles on even the worst roads.

However, since you can use EP3 and RSX bushings, I suggest searching on amazon or ebay for old stock of the BLOX spherical front bushings/bearings. I got a set for $50.

I bought cheap ebay chingo arms, and the plan is to stuff the new bearings in palce of the already shitty looking china bushings.


I gotta buy another ecu first, and have honda again, setup an immobilizer

I just finally dug a deep-ass fire pit. Time for some bon fires and beer. If you're down, I'll be having some nights in August and September where I plan on getting shitfaced and burning stuff in the heart of Taylor.

Also, I had a Sami's Popeye omlette the other morning. Goddam' addictive. Heading back in the morning for another round.


I still have those Slushies, man. A really nice Z6 and a B2. If you want'em, we can figgr' somethin' out. I'd trade you for a cup of Ohio soil or something.

Will take ALL your advice, man. Solid. And thanks!
That's crazy that your alternator / ground managed to do that. Freightening, actually.

Easiest way to find out EARLY if the alternator is looking for ecu blood, is snap it to 5500-6000 rpms while driving, and see if she cuts out and needs a restart.

If that happens, simply avoid going over 5k, find a suitable ecu replacement, and have a nearby honda dealership on your scope
