That's a common chemical test for combustion gases in the cooling system. As I stated before, unless the head gasket failure is pretty bad, that test us usually inconclusive.

1st of all thank you for reading my Question. You guys are wonderful your service is gr8t and im gr8tful. If I have blown gasket, does there have to be milky whie fluid or not. My car has been doing weird things such as idling up and down in park and jumping when stopped.I took it to a mechanic and he replaced a hose next to the engine that coolant goes through. He didnt rip me off cause I checked the hose as well. The problem persisted a few days later and I want to get down to the bottom of this. Thank you guys so much

Have blown head gasket which has been confirmed by two repair shops, suggest gasket replace with valve job if necessary, or used motor replacement (dealers idea, 3000.00). Have taken very good care of the car it has stopped only once since I bought it new. Everything has been replaced over the last two years except the carpet, air compresspor and the rear struts. Everything else is new. 3000.00 is more than I want to spend for sure, have done a head job many years ago as a kid, 73 dodge challenger, 360 with a thermoquad etc. No problem with buring oil. All miles are basically highway miles, car hits a 100 mph with no problem or strain, is steady and runs smooth even now but I wouldn't dare. I want to drive the car another 100000. Suggestions

Was head gasket failure confirmed with a compression test?

If so, then you will have to replace the head gasket and check the head for warpage.

Head gaskets generally will fail because of an overheating event, or a headbolt is broken.

Use car repair link in this thread or get a Haynes manual for your Honda and review the procedures to see if you want to take on the job yourself and have the tools.

You could replace the engine with a used one, buy a reman'd head or just replace the headgasket.

I would think that just having the headgasket replaced should cost around $1000, unless there is a problem with head (warped, cracked).

Also shop around, you may find a shop that repairs only Honda's. There is a local shop where I live that deals only with Honda's.

My car is smoking (grey smoke) and when it idles sounds like it wants to cut off. Also when I drive over 45, I hear rattling in the engine. Someone said this sounds like a blown head gasket. Can you tell me if this sounds right and give me an estimate on a repair cost?

Thank you!

Hi angeleyes63,

When head gaskets goes bad, the engine would overheat and coolant would be pushed out to the reservoir leaving the radiator empty.

Do you have the above symptoms?

Grey smoke indicae oil is being burnt in the cylinders or getting to the exhaust. That is due to bad valve seals and/or piston rings.

The nosie could be engine lubrication related rather than coolant. Did you check the oil level?

Thanks for the response!

My car did not overheat.

I had put three quarts of oil in the car the night before it started smoking and there was a tiny bit showing on the dip stick, so I wasn't completely out. It wasn't time for an oil change yet, by the recommended mileage.

No. This was the next day I heard the noise. It wasn't a loud 'knocking' or anything. It sounded like a rattling sound.

Thanks!

Without understanding the nature and source of the noise, it is not possible to provide any suggestions. You would have to try to locate the source of the noise and continue from there.

Engine Mechanical problem
1994 Honda Civic 4 cyl Front Wheel Drive Automatic 160000 miles

I recently changed the head gasket on my 1994 Honda civic, 1.5L, 16 valve engine. Last spring the head gasket blew at the #3 cylinder and I recognized the issue right away and shut off the engine. I took it to a garage and had good compression on all cylinders, except of course the #3 cyclinder. I recently chaged the head gasket and followed my Hayes Repair Manual and everything for the project ran basically smoothly. I started the engine for the first time today and on the cold start I was very pleased as it ran good and I figured with a little adjustment with the trottle body I was in good shape. As the engine started to get warmer, more and more white smoke stated coming from the exhaust. By the time it reached normal operating temperature it was smoking pretty good. I know it was water as it disipated fast and was pure white with a smell of unburnt gases. Now the only problem I can think is that the gasket did not seat properly around the fire ring. We had a little problem with the guide sleaves on the block sticking and it made the head difficult to sit on the block properly at first. We then took out the sleaves and cleaned them with some 220 grit sand paper. This made them sit better in the block and the head, but we still had to take a block of wood and a rubber mallet to get the head to seat on the block properly. We checked all around the two surfaces and they seemed to be properly aligned sitting flush. We then torqued the bolts the the specified 49ft/lbs in stages and continues with the repair. Everything else in the repair ran perfect and I figured I was good, till she started buring antifreeze again. I let the engine cool down again today and tourques the bolts agian to make sure they are coorect and they were right were they should be. My biggest question is if there would be any vacume, or coolent lines that may be switched or in the wrong place, that would cause this problem? Is there a ggod chance I need to take the head off again and replace the head gasket again? Should I replace the head bolt this time as maybe the present ones are streched?

I hate to say it, but something went wrong. In addition to replacing the gasket, did you have the block and head checked for warpage? If the head was warped, it could cause it. Also, as far as the cooling lines, there isn't anything you could have done wrong to cause coolant to get into the combustion chamber.

Check engine compression again before removing the head. Determine if it is the same one again, #3. If it is, chances are the head is warped or cracked.

One last thing, the guide sleves. They shouldn't have required you to hammar them on. If you cleaned them up, they should have slipped right into place.

Let me know what you find with the compression, and yes replace the head bolts.

Joe

Actually I took the head into my local shop. They stripped it down and I had them put new seals in it that came with my fel-pro kit. They vacume tested it and passed. It turned out to be warped by a couple of thow, so they planned it for me. There must have been something wrong with the installation of the head. I will replace the guides when I put the head back on. I take it I will need a new 200 dollar gasket, thats awsome.

Wow! Is that what the gasket cost? I do recommend checking the compression again before removing it. Make sure the problem isn't in the same place.

Let me know what you find.
