Honda Accord Engine Questions
I bought my Accord 11 months ago and has put 7000 miles on it. It's auto transmission. I properly broke in the engine and had my 1st oil change at 4500 miles.
In local and on highway, I tend to accelerate hard and rev the engine up to 5000-6000rpm frequently for passing. I know the CPU will automatically up-shift the gears on the auto transmission if the engine rev to 6000-6500rpm redline.
Will frequent and hard acceleration 'hurt' the engine? I think VTEC engines 'like' high rpm. On my Accord, the 'sweep spot' for torque is between 2800-4000 rpm I think.
What's your experience and suggestion? Thanks.

So you suggest for 'severe driving' with high rpm, the fluid change interval should be 30,000 miles instead of 50k or 60k. Please clarify. Thanks.
You should check the fluid every month (level and condition) to see if it smells, or looks burnt. You should check the fluid right after driving. That's when everything is still floating around in the fluid (before it settles back in the pan).
What rpm range is this engine ideally tuned for?
What would be the idling rpm and cruising rpm to expect ?
What rpm ranges should I expect to look for when accelerating?
Any thoughts are appreciated..
When merging, I sometimes hit 4,000 RPM if the ramp is short.
Idle, around 700 RPM.
Cruising in top gear (5th), you'll turn 1,000 RPM per 30 MPH, or speeds such as:
45 MPH/1,500 RPM
60 MPH/2,000 RPM
75 MPH/2,500 RPM
The engine is tuned to rev freely and smoothly (after 600 mile break-in), but if you keep your foot out of it, you'll get great economy (i've gotten 39.9 MPG on a trip before).
Finally, what all is involved so that I know the right questions to ask? I want to make sure that I get everything right. I plan on keeping this car for a long time.
Thank you anybody who can answer these questions.
This is the most important part. Even at the dealership, you have good, experienced techs, who know what they are doing. And you also have the guy who is a rookie, and still learning working next to him. Which one ends up working on your car, is pretty much "Luck of the draw". My advise is to find a mechanic you can trust. Ask friends and relatives who they use.
If something goes wrong, most likely Honda will make good on its error. The shadetree mechanic may or may not.
According to my '96 Accord's owner's manual, you're about 23,000 miles late to the party under normal service and 53,000 miles under severe service. I don't want to frighten you into a panic dither, but Accord engines are "interference" designs which will destroy expensive internal thingies if the belt breaks in operation and an irresistable force in the form of moving pistons slams into equally immovable objects in the guise of partially open stationary valves. It's time to get very serious. Another item up for prophylactic replacement during a timing belt changeout is the timing belt's autotensioner, a nifty device that properly tenisons the belt over its expected service life. Most of the charge involved with a timing belt replacement is the hourly labor charge - an avoidable premature repeat of which is cheaper in the long run. As some unknown bit player in the role of a sleazeball mechanic said in a mid-'50s era oil filter commercial regarding preventive maintenance, "Pay me a little more now or a lot more later." (then drove the point home with a deliciously evil grin).
So thank you for your time.

Anti-freeze, in addition to protection from freezing and increasing the boiling point, has quite a bit of 'lubrication' capabilities. It helps keep the shaft seals 'lubricated'. With straight water, the shaft turns on the seal without this lub, and then leaks.
If you don't believe this, stick your finger into some, either 50/50 mix or out of the jug, rub it between finger and thumb, just feel how slippery it is.
This is why owners manuals caution about always using antifreeze in the coolant system.
Once again thank you for you story so now I know more about what could go wrong with the car.
You could always decide to
But I wouldn't...
...Big bucks, big bucks, no whammies!
I thought it got the point across quite well, if I do say so myself.
Best,

Thanks anybody for responses. I like this board because everybody seems to know what they are talking about.
Again thanks for the response.
This may sound dumb, but is there any real reason why one would use the manumatic shifting, meaning 1,2,D3,D4? Is that for greater control on ice and in slippery conditions?
Honda sez there was a catastrophic oil loss and filter was incorrectly installed and failed. Oil filter was buldged out at end, a sign of major oil pressure. Honda sez gasket was incorrectly installed by quick lube guys.
Quick lube guys (oil change 4k miles ago) say oil pump pressure relief valve stuck and that blew oil filter due to high pressure.
Any ideas on how I independently can confirm what happened???
Honda sez timing belt broken and crankshaft bent...engine is fried and will cost $7000 for rebuild...
Thanks, John
Now, at best you can try to get the "quick lube" shop to call their liability insurance company. $7000 is probably half to 75% the value of your car.
That would be logical if every dealer charged $24 for an oil change. Unfortunately my dealer recently changed hands, and prices for oil changes went from $23.95 to $38. Outrageous. I'll be going there for the length of my warranty, then I'll have it changed elsewhere. I'm already taking my old 1996 (174,750 miles) to Texaco/Jiffy Lube.

I don't think your engine has a timing belt. If you have K-series engine, which I think was introduced on the 2002 CR-V/Element and was installed on the 2003 Accord, then you definatly have a timing chain.
Did you see the buldged out filter? I think, ultimatley, it is Honda vs the Jiffy lube. After seeing the hidden camera videos from Jiffy Lube, I would not doubt that Honda will win.
Let us know how it goes.
Sorry to hear about the original poster's misfortune.
Unfortunately, I'm not sure how you could prove or disprove anything at this point. Either way it's outside of the warranty period, correct....so Honda isn't on the hook to HAVE to pay for anything.
You might consider replacing the engine with one from a pre-owned wrecked vehicle (side or rear).
If it doesn't stop, then the problem is internal to engine or transmission.
External accessories are usually the problem.
I just have a question. Yesterday I was on a website comparing these two vehicles and it said that the 03 was rated at 160 Horsepower at 5500 rpm and the 2008 is rated at 190 Horsepower at 7000 rpm. It makes sense that there would be more power at higher rpm's, but wouldn't most people want to keep the engine out of redline? Isn't that what we're always told to protect the engine?
Anyway, since the one is rated 160 at 5500 and the other is rated 190 at 7000 wouldn't that mean that they are both about the same? I'm not positive about this, but it's just been something I've wondered about.
Thanks to any who respond.
When i try to put my gear from neutral/drive to D4 of the engine. it would take about 1.5 seconds to accelerate.. is this also a problem? tnx..
It's close, but not quite redline. Redline starts at 7100rpm.
Not to nitpick, but the 2003 Accord LX actually has closer to 156 horsies based on the new rating system for hp (if you are comparing apples-to-apples - the 2008 Accord uses the new SAE test procedures for hp).
Also, the 2008 Accord LX has 177hp, not 190hp. The EX and EX-L models have the 190hp at 7000 RPM. The LX model's 177hp engine doesn't rev quite as high.
Just so we're on the same page, the numbers I was looking at were on www.kbb.com comparing a 2003 LX Coupe I4 with a 2008 Coupe LX-S w/out PZEV, the LX-S seemed to be the closest match to what I have. Both were automatic. I went to the compare section to get the info. I know that site is wrong about a lot of things, but I would think those numbers would be fairly close.
I don't know how to link to other websites or I would have.
They are mostly wrong with accessories. Like with mine it said that the immobilizer wasn't available and I have it. Anyway you can look and tell me I'm looking at the wrong numbers. I guess it's just a case of curiosity killed the cat.
