So everyone loves k series. its an awesome swap to do if you have the funds and ability. however, if you go through what i do then you might not enjoy the k as much as everyone else. I am on my 3rd piston and ring replacement job in 10 days. I am doing it on k24s in 08 accords. if your asking why its because I work for honda as a tech. and everyone knows the k24s from accords in 07-08 and some 09s burn oil excessively/ so honda has us replace pistons and rings and pay us 13.2 hours. I have luckily been able to do it in 6.5 hours. bring the car in, tear it down, and put it back together and test drive. there are worse things out there. on the plus side i know these like the back of my hand now.

also sorry for this being in the civic section. just figured people like k swaps and didnt know where else to post

 

We have a Hybrid section. Since no 92-00 Civic came with a K-series engine.

 

Sorry. Mods please move to approprate section
Thanks

 

that's why nobody swaps those k24's in stock form. the only k24 worth a damn to drop straight in is the k24a2 from the tsx.

 

so the moral of the story here is you can do a head pull in half the time and/or make double the money for it?

 

I think he means the k24s from accords in 07-08 and some 09s burn oil excessively/ so honda has us replace pistons and rings. So people now know those K motors have a weak spot.

 

apparantly he thought i was just trying to say how fast i could do it. but yes. i was trying to say those ones are junk and it makes you not want to look at a k series when you have to fix em constantly for little pay

 

Thats rough. I didn't know dealerships did overhaul anymore?

 

Good to know. Thanks for the heads up

 

Hmm that's funny I have been working for Honda since 2001 and have never replaced pistons on an accord, let alone for 13.2 hours..... The new si however has a problem with some blocks having the wrong pistons installed and after an oil consumption test there is a recall for piston replacement which I have done several of for let's just say alot more the 13.2 hours....

 

well believe it cause I have been doing the same thing too also I just did that to a 2012 civic si , but its whatever , tho its fixed now

 

I had an '07 Accord that burned oil from the day I bought it (new). This is the first time I've heard that it's an actual "known" issue. Thanks for sharing!

 

this goes to show dealers all around are getting different stuff. ive yet to hear about any si blocks with wrong pistons. online host i cant believe you havent seen any of these accords burn oil. theres actually a bulletin now.
dougnuts if i were you id bring it to the closest honda dealer and tell them about your problem and they should be able to help you depending of your honda rep. we warranty everything at mine and ive done a piston and ring job on one with over 100,000 miles

 

good info...most people who use the accord blocks usually swap the head for a type-s or tsx,which will require the use of aftermarket pistons..there are valve-piston clearance issues with the type-s/tsx heads on accord blocks

 

True statement.

OP, have you seen anything on CRV motors?

 

nope. yet to see any problems with any of the crv motors.
and i never mentioned this but most of these oil burning issues is mainly because of the dumb maintenance minder system. it has these cars going a min of 7500 miles sometimes even 9000 miles between oil changes and thats if the customer actually does it when the minder says to. i like to check the history on the cars i get and sometimes they have only had on average an oil change every 10,000 miles and yet they expect the motor to be perfect. haha

 

How long do you normally prefer on those? 3-4K like normal?

 

I change mine every 3k based off the odometer with royal purple 5w30 and honda filter, all i do is city driving.

 

i preffer 3,000 miles on any vehicle no matter what oil or manufacturer. i dont get how any car manufacturer can think that the car can determine the life expentency of oil and when it breaks down enough to change it. oil changes have been done 3000 mile intervals since the beginning why change now.
on my personal cars i hate going over 3000 so even at 2800 i get ready to do it. i have a 98 mustang i change the oil in once a year and i dont even drive it 2000 miles in one year. i change it in the spring when i take it out drive it then it gets put away.
id love to see people with 07-08 accords change their oil every 3000 miles and i bet they wont have oil burning problems

 

I didn't change mine at 3k (does anyone anymore?) but I rarely let it go until the minder told me to change it. I sold the car a few years ago @ 88k miles and it burned oil every oil change, including the first one.

 

you seem to love wasting money. can YOU determine the life expectency of oil and when it breaks down with the naked eye?

you make it seem like the engine will instantly seize up at 3k miles if you havent done a change yet. i guess oil technology hasnt changed since 20 years ago.

 

That's another good point I forgot to mention....I had multiple black stone analysis' performed and they all said I could go further on my oil changes. My guess is that Honda went too smooth on the cylinder walls or used rings that allowed too much blow-by.

 

Honda had this same problem in England when the K-series was first introduced there, except in that case they were replacing the entire short-block. What they should've been doing is replacing the drivers! Something no one here has brought up yet is, what's the root cause of excessive oil consumption to begin with? Inadequate ring sealing is at the root of all of this, and in most cases its the ignorance of the driver that causes it. Its deeply engrained in the British mind that engines need to be "run in" (broken in) slowly and gently, and while that might have been necessary with English made engines of decades ago its certainly not the case with current Honda production engines. In fact its the worst possible thing you can do.
Seating a ring-set to a given cylinder bore is a lubricated lapping process where the effective cutting edges are what you see as the 'crosshatch" pattern in the cylinders. With the rings and crosshatch Honda uses the rings can be seated sufficiently to achieve less than 2% leakdown in about a half hour if its done properly, and "done properly" means putting your foot deep into the throttle over and over again. If the rings aren't loaded HARD against the cylinder walls there's very little or no lapping action taking place, and once the cutting edges are worn down there's no way to lap the rings to the cylinders and you're forever left with an engine that doesn't make as much power as it should, and one that burns a lot of oil.
The long oil change interval caused a lot of English drivers to run their engine out of oil completely, hence the short-block replacements under warrantee.
The kind of people who buy Accords will probably never put their right foot down on the pedal hard in the entire life of the car, so it makes sense that they're the cars you're having to do unnecessary work on.
When I break in a new engine its in break in mode until I see the leakdown at 1%, then the oil and filter get changed. Since I build racing engines all of this happens on the dyno within the first hour of the engine's life before it ever gets installed in the car, but its actually easier to seat rings when driving the car on the road if you know what you're doing.

 

Thank you for saying this!! I've been preaching this as long as I have been involved in this industry. I know its not a new process or theory... many builders out there believe as we do but its not shared in public forums! Most of those that know dont frequent these places.

I've been met with disbelief or funny looks and its nice to hear it from you because you are respected (at least in my book). Lets just hope a lot of people read this!

 

does honda fix the problem for free?
