My car acts funny when i start it up in the morning.......the idle would drop as if its about to turn off, then jumps back up to 900rpms, then drops again. I rev it up to 2krpms and keep there for 5 seconds, letting go of the gas it sits right on 1,000rpms.

I notice the car it blowing blue smoke out the muffler and oil on the ring of the muffler. Can anybody tell me whats going on?

 

blue smoke ususally is a result of burning oil. check your gaskets and seals, oil might be getting into your cylinders...

 

head gasket

can jump to conclusion...if it was the head gasket he'd more than likely be losing coolant along with the oil. are you sure it ws oil on the ring of the muffler or condensation that mixed with the soot in the exhaust???....also check you PCV and see if its good...i know its weird but that little thing can cause your motor to burn oil,...if its good get a leak down and compression test.....goodluck...when i had blue smoke at start up my valve seals were shoot

 

also do a compression test to see if the piston rings are bad or not

well....if just the oil control ring is bad a compression test wont show a compression loss...but its worth it to do one....check the oil level....might have over filled

 

If it is only in the morning, then it is not really ring or gasket, but more like valve sterm seal. Getting those fix is much cheaper than ring or gasket.

 

blue smoke! sounds awesome i wish my car had blue exhaust

Please tell me your joking.....

 

i have some liquid in my tailpipe, but it's very thin, viscosity-wise, like water. not sure if it's oil or water, but i'd guess it's water since the products of a hydrocarbon combustion reaction are carbon dioxide and water. FYI, i have a 2.5" 49-states legal cat, 2.5" exhaust, and bullet muffler w/ silencer.

 

My car used to run similarly in the mornings. Honestly I just didn't care, let it heat up a bit and it was fine. It's most likely a faulty cold-start valve, basically what it does is keeps the car ticking over when it's cold. Take it ou and give it a good clean out with carb cleaner or something similar.

Anyway the blue smoke means the engine is burning oil. What happens is before the engine heats to its running temp. and everything has expanded to it's nice snug fit oil will run into the combustion chambers and be burned. don't worry about it, as long as you keep an eye on the oil level and keep it topped up it'll be fine. Japanese motors are notorious for burning a drop of oil, I wouldn't be overly concrned about it.

Hope this helps.

 

i bet it is you spark plug grommets. Happens to all hondas sooner or later. Just get a new valve cover gasket that comes with the spark plug grommets. And at the same time you can adjust the valves

did mine a couple years ago.

 

yea i was joking but cmon that sounds awesome.. take a picture

 

ur burning oil man. check out the head gasket

more than likely if his headgasket was bad he'd be losing coolant and have white smoke...also his oil would be milky

Now how is the oil going to get though a spark plug i don't think that it will. you are not going to be burning oil cause your gromets are going bad. I thonk that it is either your rings or your valve guides. Since your not burning coolant your head gasket is fine. go to a shop and get a leakdown test it witell you what is wrong. If you are that worried about it.

 

ive seen it a million times on Hondas at my shop. They say that there is blue smoke coming from the muffler and dont know what it is. I pull out the plug wires and they are coated in oil. I tell them to go get the valve cover gasket and spark plug grommets replaced. ALL of them come back and thank me for saving them alot of time and trouble and has fixed every one of them.

First i would pull out the plug wires and see if they are coated in oil. I bet they are but if they arent, then it could be your piston rings or head gasket

Good luck

it'd more than likely be the valve stem seals

 

Just because your oil isnt milk and its not loosing coolant means nothing. you can have a blown head gasket and not have milky oil or burn coolant. i would exhaust all options before i would spend hours tearing off the head and theres no way on gods green earth that oil on your plug wire will make it burn oil.not possible. misfire yes studder yes burn lean or rich maybe but not burn oil.oil has to get in your cylinder to burn. i would start with checking oil level and pcv, next valve seals then last head gasket then rings. also a leak down is a good idea. How do your plugs look??some of the time if you blow a head gasket only 1 or 2 plugs will get oil in the pistons. good place to start checkin.

and i heard that a compression test would show loss in adjascent cylinders. i can see how the plug gromets can cause oil to leak into the cylinders

 

and around and around we go...

everything everyone has said is right in SOME cases.

we need the results of a compression and leakdown test before we can bother trying to diagnose. Also pull out the oil dipstick and check for FUEL smell in your oil. Also note the rpm at which the blue smoke is worst. Is it when you mash the gas at idle, or mostly at higher rpm??? Also check your coolant to see if it has been contaminated.

With this info we can be more likely to pinpoint your actual problem instead of just guessing.

 

Most of the blue smoke at regular idle, im going to check it out tomorrow becuase i didnt have a chance to look at my car today. Hopefully it is the plugs because i dont want to replace all of my gaskets and start ripping out the head. This will be my first time doing engine work if the headgasket is blown.
Wish me luck guys and i hope my head isnt warped.

when i had smoke at idle it was my valve seals,,,the smoke only happened at idle and start ups

 

the car is overheating and starts up really wierd..........i have to give it a lil bit of gas till it sit at 1,100rpms. there isnt any smoke while i'm driving just when its not in gear. Everytime i start it i have to give a bit of gas till it sit at 1k rpms. Does anybody know why it's like that?
