  • hi! can someone help me with the strange noise on my honda accord 97 model. it sounds like my bearing squeaking and usually when the engine is warm already, if i step on the gas. the sound will disappear. i tried changing bearings from timing belt, also water pump and, still the sound is there. i believe its on the left side part of the engine (facing the engine). is it my transmission? i have automatic transmission.

    Take the accessories belt off, start the engine, and see if the sound is gone. If it is, then one of your accessories (or the tensioner) is bad. Turn the pulleys by hand, and see if you can feel or hear the problem.

    If it doesn't stop, then the problem is internal to engine or transmission.

    External accessories are usually the problem.

    I'm having the engine on my 1999 Honda Accord 4 cylinder sedan replaced (turns out it had a blown head gasket when I bought it and the engine had been seriously abused. Just easier to replace it.) The problem is, there is a connection at the very back of the engine, underneath the plenum, that doesn't seem to have anything to connect to. The Honda dealership/maintenance guys say that yes, it is supposed to connect to something. We've looked in the aftermarket maintenance books and can't find anything. When we disconnected those connectors from the original engine, one of them totally disintegrated. At present, the newly installed engine won't start. Any ideas? :confuse:
  • Hey all-

    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.

    They are both 2.4 liters. The torque is about the same. I would think the 190 would be more fun with a manual and less noticible with an auto. Search the threads,someone was comparing them and/or test drive them both in you preferred configuration to see which you prefer for the money.
  • hi kiawah! thank you for replying to my problem.. i'm not really sure but my suspect is it might be my transmission.. any ideas how i can fix that? or how much would it cost to fix that?

    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.

    tankbeans,

    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.
  • You say tomata I say tomota. ;) I was just curious. I thought it was weird that they would rate one at 5500 and the other at 7000. That must just be the new standard for rating. Not that it's important or anything like I said I was curious.

    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.

    I've gotcha now. When you said just "LX" I was thinking Sedan (the only model that comes designated as such now). All 4-banger coupes have the 190hp engine.
  • Sorry about that. I just assumed that they would have the same engine specs. I forget that they are completely different now. The two new Accords Coupe vs. Sedan don't even share the same lights. I know with all the options available it is very confusing to try and figure out what is what.

    no problemo! Merry Christmas!

    This operates just as my 1996 2.2L Accord LX does. That isn't a problem, just the nature of the transmission - it takes a moment to engage. I have 177k miles on my Accord, and the transmission has NEVER been a problem.

    I can't answer your other questions, but they might be able to in the 1994-1997 Honda Accord Maintenance and Repair forum. Good luck! :)
  • tnx for the advice thegraduate.. i'll try to check on that forum. btw, when i try to bring it to a mechanic before, they cannot find where the sound is coming from. so weird. :D
  • thegraduatethegraduate Posts: 9,731
    That is odd. Best of luck accord 97, sorry I couldn't help you any more; I'm not very mechanically inclined!

    I have a stupid question, but it's something that's been nagging at me. What the heck do the liters in an engine correspond to? I mean what does it mean? I know that the greater number of liters means the larger the engine and the more gas you're going to use, generally. I don't think it corresponds to the amount of gas in the engine at any given time and I know that it doesn't correspond to the amount of fluid, transmission, coolant, brake fluid, etc. I'm a moron I know, but this is been a question that's nagged at me since I started driving. This may one for the gear-heads out there who really understand the internal combustion engine.

    By the way, lest ye get offended, being a gear-head isn't meant as an insult.

    I know this a completely random question, but I've wondered for a long time and have never gotten a straight answer.

    The last answer I got was that a liter equaled 56.5 cubic inches, but that still doesn't make sense.

    Signed,
    Confused Automotive Moron :blush:
  • you know that your engine has pistons, and the pistons move up and down in their cylinders.
    When the piston moves from top to bottom, it sucks in a certain amount of air. How much air it can suck in depends on how big around the piston is, and how far it moves when it goes from top to bottom.

    Let's say that the piston in your car is 4 inches (10.16 centimeters) in diameter (also known as the bore), and it moves 4 inches from top to bottom (also known as the stroke). That means that one piston in your engine can suck in:

    radius ^ 2 * pi * height = volume of a cylinder
    5.08 cm (bore/2) ^ 2 * 3.14 * 10.16 cm (stroke) = 823.3 cubic centimeters

    If your car has 4 cylinders, then it has a has a total displacement of:

    4 * 823.3 cubic centimeters = 3,292.1 cubic centimeters, or 3.292 liters

    A car manufacturer would round that up and say that your car has a 3.3-liter engine. This means that the displacement of this particular engine is 3.3 liters. If you were to turn the crankshaft of this engine through two complete revolutions, the four pistons would inhale a total of 3.3 liters of air.

    For example, the capacity of the Accord's "2.4L" engine is actually 2,354 cubic centimeters.
