    Hello, I am new here and pretty sure this is where I should post this. =)

    My 93 civic has white smoke coming from the exhaust when it is warmed up. Previous owner had no antifreeze in the radiator, just water... I got the car about 2 weeks ago.

    Oil does not appear to be milky
    Car has a very harsh idle. (sputters and wants to die.)
    Started car with the radiator cap off and bubbles came out of radiator.
    Radiator appears to have small shavings of metal in it? or something metallic.
    Took out sparkplugs that I replaced about 3 months back all appear to be looking good but one is a little orangish and stand out from the rest. looks like it got burnt or something. (oil was on plugs)

    What I have done so far.
    Drained radiator and flushed it out with water
    Pulled plugs and checked them. (stated above)

    Pretty sure it's my head gasket. Just started happening, hopefully its not the head. going to buy a book for my car and replace the gasket if that is the issue and replace my timing belt while I'm at it.

    Thanks for any advice, Joey. =)

    Edit, this is my first post not sure what else I should add but engine has 190,000 miles and it's the stock engine. nothing modded. automatic.

    Seems like the HG is on its way out but hasn't COMPLETELY failed yet. And since your changing the TB might as well change the tensioner and water pump while your at it since they are all together anyway.

    Another thing. what the trim level of your civic and what engine do you have in it. Knowing the engine will allow the others here to help diagnose issues and give pointers that may be engine specific.

    have the stock engine. not really too smart with cars lol :P
    this will be my first time tearing one apart besides replacing plugs, thermostat and other stuff lol.

    will be doing this with the book and online instructions. Will also have a friend help me who has the same car and always messes around with his. (he knows about the fuel system and stuff) only part I think I may be confused on.

    yeah, Thinking about buying new belts, tensioner, will check my TB once I take it all apart.

    Also how would I go about finding out what my idle is set at? It's a automatic. Will a car tester tell me my idle? My gf's grandpa has tons of tools and car testers he said I can borrow. Just wondering for when I start putting everything back together lol

    1. do you know if you are burning oil
    2. the previous owner could have used a liquid gasket to fix your car, thus copper or metalic flakes could appear to be in the radiator
    3. how much bubblding is going on?-is it one or two small gasps every now and then or is it foaming?

    since theres no coolant in your system and just water, your oil will is not going to be milky. drain your oil and see if theres water in it. water and oil don't mix well so you should be able to see it pretty well.

    not burning oil.
    have metallic flakes in radiator.

    Will drain oil on monday since that's payday and post back with results =) Pretty sure it's the HG since when I bought the car they said I need a new radiator cap since it burns water.

    Kinda funny since I got the car from my parents brother lol.

    Well, oil looked pretty bad and i believe there is water in it.

    going to replace HG in around 4 days. anyone know about how long it will take? going to try and get it done in about a hour and a half. Tearing it apart that is. Then paying a place near here 40.00 to check out my head. Will be having a friend with the same car & engine as me help. =) this will be fun lol

    Hello i have a 94 civic dx and it had a blown headgasket when i bought it. It can be time consuming depending on what tools you have to work with and your level of experience, but it is a great way to get to know your car. Take your time and make sure everything is right. Dont cut corners and you;ll be ok

    alright its a b7 I guess, found it located on the bottom of my engine :p

    but I'm guessing pretty much all i'll have to remove besides the head is the timing belt, plugs, wires, and distributor? Seems like that's the only stuff in the way. Took some pictures just to show you =)

    But that seems waaay to easy lol. Or do I gotta remove everything around the head? Already drained radiator and oil. :P

    Thanks for the help so far everyone! kinda hard at first when you have no idea about cars lol.

    The belt has to be removed, valve cover, exhaust, and intake manifold, then the head should come right out. NOTE! be sure to remember the location of the bolts holding down the head. If i remember correctly there are four of them that are longer than the others and you want to make sure they go back in the same. Do you have a manual? Your going to need the torque specs when putting back together. Removing the stock intake may be a little tricky, as the bolts are a little hard to get to. If you have that problem and find yourself stripping out the bolts, stop. you can find behind it where it is attached and undo that bolt whick wil allow you to lift the head with the intake still attached up to about a 45 degree angle which will allow you to get at the head to clean it and replace seal.

    You'll have to remove the distributor first, then the valve cover, then remove the belt, then the cams, then the head bolts. Oh and the exhaust manifold. Leave your intake manifold on though, if you get under the car you will see (i think 2) bolts holding the Intake manifold down, just take those out n you can remove the head with the intake still attached. Then take the intake off once the head is off if you are having it shaved. When you put it back on make sure you tighten the head bolts in the correct pattern and torques, and just make sure when you set your timing you set the cam and the crank pulley to TDC. I always buy cheap sandwich bags and mark the bags with what bolts are in them and seperate everything. Will be a lot easier on you when you put it all together again.

    Thanks for all the help so far!

    Just got a 195 piece tool set =) But when I take off the timing belt and put it back on will my timing be messed up? Heard I will need a timing gun to get the timing right.

    going to start on removing everything so all I'll have left is the head on Monday (payday) =)

    Also, I heard there are springs inside the head that will shoot out, is that true?

    alright so far i have done

    took off distributor
    took out plugs and wires off. (left them on dizzy)
    Took exhaust manifold off.
    Took air intake off.
    all hoses off head.

    But I am a little confused.
    How do I make sure the timing is right when I put belt back on?
    When do I put my engine to top dead center?

    And when I take my headers off, I'm not sure what to do. lol I am scared. Are there fuel hoses connected to the headers? Was just wondering since the fuel injectors have to come off also. Or can I just take out the bolts and slip the head out with the Headers still in the car?

    I'll do some research while waiting for a reply =) this is going easier then I expected lol thought I was going to get stuck even with what I just did. :P Already took the valve cover off but put it back on since I wasn't sure if I needed to TDC my engine before taking the TB off. :P

    you have alot of guts doing that yourself. hopefully you do everything right. If you mess up something it will cost you even more. I found a place near my home, Inland Empire that work on honda cars and got my HG replaced for 400 bux. plus another $40 to replace other gaskets on my own. Most mechanics where charging me 800-1000 bux for my 97 honda civic ex.

    But dont forget to change your gaskets as well. there is one behind the head that connects to the intake that the mechanic replaced. change the head cover gasket, its so cheap. Mine started leaking because the old one could not be re-used. And hopefully you are using a genuine honda head gasket. dont go cheap with that part by legit and you should be fine.

    Also, Just make sure you have a torque wrench at hand, because you want to torque the bolts to exact specifications, if not you could snap them off and will give you more headache. I get mine loaned from Autozone for free.

    well i got a nice understanding kinda searching on the throttle body right now, will be changing gaskets as needed. Only thing i may have a problem with would be the timing lol. But then again I don't have a book (getting one tomorrow) =) should be a lot easier then trying to find answers online :P

    will be using a torque wrench =]
