My 2007 Accord with 666,800 miles (Valvetrain Shots)

[tbm3fan]

Have lobes that show similar wear pattern on my 98 Sable cam with just over 200,000 miles. Surprised me but I didn't own the car it's first 10 years. No matter as there is a brand new engine waiting to be assembled for it.

I'll probably try to look into buying another 06-07 with lower mileage from a non-rust state if this one dies.

When my wife gets bored of her's, I'll call you.

Looks like a good case for the use of higher viscosity oils.

might have made it to 700,000 with better oil

 

[Bjornviken]

666k miles, that's insane . Change the cams and run a other 600k

 

[Sequoiasoon]

I'm thinking Berryman's piston soak and VRP in like 5w-30 to maybe get rid some of the piston ring oil issues if possible.

Even if not it's at least pretty good oil.

 

[dnewton3]

Be a real BITOGer ...
Put new cams in it and run some Amsoil or HPL loaded with ANs to liberate the ring pack.

See all you have to do is change your oil with a major store bought brand and you will be fine...No H igh P riced L iquid needed....

Unless it could have avoided the lobe wear and oil consumption

Very impressive. I would run it until it starts misfiring and then scrap it.

In regards to oil choice, it would likely make little to no difference IMO.

Indeed, if there's a materials issue with the camshafts, it's unlikely a different oil would have made a difference. My above comment is a bit tongue-in-cheek based on a recent interaction on this same subject.

I do think there may be some merit about the impact on oil consumption though.

 

[SatinSilver]

I paid $2700 for it 8 years ago. I think I got my money's worth.

I think I remember when you first bought it and posted about it. Did you buy it from a Honda dealer if I remember correctly? Surprised they weren't asking more since the exterior looked so good.

I attempted to change the valve cover gasket on my long-leaking high-mileage Accord yesterday, but one of the nuts holding the valve cover on was stripped and would not come off. I decided to take it in to the dealer to have them do it, and adjust the valves while it was there. I asked them to take some photos while the cover was off, and here is what they sent me. In the 95k miles I've owned the car, I haven't adjusted the valves or had the valve cover off. I am not sure if the valves were ever adjusted before. The timing chain is original, as far as I know. The previous owner put 571k miles on the vehicle, bringing it to the dealer about once a month for an oil change (every 5-7k miles). It burned a lot of oil when I got it, and I suspect it may have been run low on oil a few times based on the large wear scars on the cam lobes. It still runs well, but the wear on the lobes tells me it may not last a lot longer. Hopefully I can get a few more years out of it, as the body is too rusty to justify replacing the engine. They may have already been heavily scarred before I got it, as I never run it low on oil... but who knows at this mileage. It does look exceptionally clean otherwise, probably due to the constant inflow of fresh oil every 1000 miles or so. Enjoy!

Would you know the approximate oil change interval the car had for those 667K+ miles and what brand/type/viscosity oil was used.
That's the first question that comes to mind for me when I see a high mileage vehicle like the one you have.

it’s in his post. previous owner did 5-7k intervals at the honda dealership. Honda spec’s 5w-20 for these cars and a filter change every 2 OCI’s.

 

[jkasch]

Waiting for a smart *ss Restore & Protect post.

 

[Warlord]

If I got to 666k I’d be very tempted to try to get it to a million. I would then bring it up ad nauseam in general conversation.

You are taking over half a million miles on that car...most other cars are already in the junkyard...

Yep, I know. Remember those discussions about at what point it might make a difference to run a higher quality oil? IE, how many miles would you need to accrue for it to become relevant? Well, that dovetails with this discussion.

 

[We're Metals]

Bad cams yes, but I would just run it until it dies.

 

[ecotourist]

Someone recently posted about having just covered 1,000,000 miles with a 2007 Honda Accord V6 6MT 2 dr. That engine had never been opened (unless you count cam belt changes).

For the last 40,000 miles or so there was a burned exhaust valve. He later posted about the tear down results. That valve was too tight.

I don't remember whether there had been any significant oil consumption.

 

[ecotourist]

I have a 2007 Accord V6 6MT 4Dr. It has about 120,000 miles on it. Bought new. Getting its second set of tires next week.

I've always run 5W-20 in it. Seeing those cam lobes I may switch to 5W-30 when my 5W-20 supply runs out. But that'll be at least 5 years.

I plan to have the valves adjusted by 500,000 miles

 

[LongTime_Lurker]

If my main lobes wear out I'll just get a tune that makes VTEC kick in all of the time (yo).
