You have to remove all the electrical and mechanical parts till you have a good view of the head and are able to pull it out of the engine compartment, then just remove the old one and put the new one on and bolt it down, its a long job.

I have a 96 Civic EX, 124k mi. Last week driving from Boston to NY and back I notices the temp gauge get up to red line. Brought it in to a local garage and they saw oil in the coolant reservoir, diagnosis head gasket leak. They wanted $500 to repair. A slightly less shady garage quoted $909, as did the dealer, so I took it to the dealer. They call this morning saying that the reservoir was melted, indiating etremely high temps, which may have caused cracks in the engine, too. If this is the case the repairs would add up to $2500, if no cracks $1000. Does all this sound reasonable? Problem is, they won't know if there are cracks until taking apart the engine, which will cost $500 (included in the total repair costs given). Should I take the car somewhere else and just swallow the $100 that Honda took for their initial diagnosis?
Thanks for the advice

Well, I would be concerned about repairing the engine if there is a deeper problem in the block. However, there really isn't much of a way to find out if the problem exists without pulling the head off. There could even be the possibility that the head is warped bad enough that it can not be planed. So, I would entertain a couple of ideas that would range from a rebuild, purchasing a new or used engine, all the way to getting a different car completely.

1992 Honda Civic 4 cyl Front Wheel Drive Manual

Hey, I got a 92 civic and I was out one night and ofcourse my headgasket blows, but I was 1 hour away from home and I did not have any money for tow truck or anything. Desperate times makes us do Desperate risks, so it took me about 3 mins to get it started and i'm driving down the highway about 50-55 on a 65, (good thing this was at 2-3:00am when this happened)
i figured since it was winter time the cold air might help cool down the engine, which it did, but not good enough. I finally made it home and my radiator and it's resivor was boiling spark plugs connected to the plugs was melted to them, the timing pulley/belt cover was also half way melted to it aswell. Next morning I go look and disassemble some parts and the radiator was fill with this black oily muck, also the resivor was fill. I check the dip stick and surprisingly the oil was still the same color when I added it. I took the header cap off, everything looked good. Other then those things, I was able to turn it on, I was shocked what a trooper this car is. But shut it off took some parts off but havent done much to it since. I want to make sure if theres any internal Symptoms I may not know about, so my question is, other than the hoses, radiator, gasket, etc. What els you think it could be wrong? Because people say don't drive with blown gasket but I had no choice, so 1 hour drive is long, and I know I have done internal damage, just wondering what internal damage when I dont got any coolant mixed in the oil. Im just in a super buget and I know im a self fixer unless its major requiring block and header replacement or refernishing them. I have high hopes for this motor.

Thank you.

Thats quite the predicament. First thing you must do is get a cylinder cmopression test, wet and dry on all the cylinders along with a leakdown test. That way we can find out what damage is possible with the vehicle

My engine was rebuilt less than a year ago, within that time, a head gasket blew, my mechanic says it could have been from a leak in the radiator that caused it. It got fixed, and ever since it has not had the power it used to, it hickups every now and again sometimes causing it to die.

It has always hesitated when getting up to a higher speed, the hesitation usually happened right around 25-30 mph. Now, it does the same hesitation at three different time during the speed up.

It never used to hesitate going up hills, now it does.

It is acting like it has bad gas in it.

What do you guys think?

Hi there,

Since you mentioned lack of power and also tendency to stall, I believe it should be the carburettor accelerating pump.

Check the ignition timing to ascertain lack of power is not due to rertarded timing.

If the distributor vacumn and/or centrifugal mechanism is stuck, you also lack power.

Engine Mechanical problem
1996 Honda Civic 4 cyl Front Wheel Drive Manual

Well first off I have a 96 coupe powered by a b18c. All round teins 4wheel discs with willwoods, car works fine for the most part but I have a problem with the engine that seems to b baffling my friends and I have little mechanical knowledge.
Here goes, im used to an idle between 1000 - 1500 rpm or around 8000 rpm with a/c on. Now I find that I idle at 7000 rpm with a hard start (unusual). Personally it sounds like the car is misfiring, and it sounds like a damned lawnmower =
i have to give it gas to start which is unusual aswell and recently I changed my plugs and saw oil on one dont think that thats a good sign.I overheated once but dont know if thats related, dont think my headgaskets blown as my radiator dosent bubble or spit back water and im not gettin an engine check light so I cant diagnose myself. Plz help =/
if u can it would b much appreciated.

Hi transplant-civic,

Cold start rpm should be between 1500 to 2000 depending on engine and ambient temperature.
After warming uo, it should be about 700 rpm.

If during cold start rpm drops drastically and engine seems like misfiring, it could be due to valve clearqances too tightly adjusted. Readjustment should solve the problem.

It could also be due to failing head gasket, there are minimal leaks resulting in compression leakages when cold. Are you losing coolant fromthe radiator and the reserve tank is always higher than what you put in? If yes, the head gasket and cylinder block surface have faults.

If the idling speed is too low after warming up, you need to clean the throttle body an IAC (Intake Air Control) valve. Misfiring could be due to spark plugs or wires that are bad.

Our son's car overheated. Turns out it's a head gasket. 1989 Honda Civic under 100,000 miles, standard transmission. Distributor cap damaged from heat. Spark plugs are blueish. One cylindar is 150#, the other 3 are 50#. 4 questions-
1.) Is it worth repairing;
2.) How much is a reasonalbe price to repair if just the head gasket is blown?
3.) If the head is warped or cracked?
4.) If the motor is cracked?

Thanks.

It sounds as though you had a compression test. It was not good and though I might suggest a leakdown test, I don't know that I would spend all that much more on the vehicle. Those 3 weak cylinders are going to continue to drop. The car will run very poorly and the expense of the work will not pay off. However, as I think about this some more, let me say that the compression test on a vehicle with a bad head gasket is really not that accurate. I would venture that the head gasket is sooo bad that compression is tough to read.

Even if the head needs to be planed, it should not run over an extra $100 and should be less than that. Now, the labor is the problem. $600 is about what I might expect for the whole process, plus the distributor if it needs to be replaced.

Here is my last comment, I don't know where you live and I don't know the age of the son. This car got hot and I mean real hot. I would abandon repairing the car, mark it down to experience and get a different vehicle. I wouldn't stop there but I would note that driving this vehicle to the point that it was showed very poor judgement or lack of knowledge. Anytime that temp gauge elevates from the normal position that it is used to being, I would be looking for the problem. It will be there and then you can prevent this type of major loss.

My machanic thinks my car has a blown head gasket or warped head. Which I dont believe because my car runs and drives good. It does not smoke, overheat or loose coolant and the oil is clean. After the car warms up at idle the check engine light comes on and rpms drop down below 500 but car does not die also the light comes on if you rev over 4000 rpms when driving. Most of the time it does not start on first try.

The head gasket is blown or it has bad head or possibly cracked block because it is now leaking coolant that is mixed with oil and white smoke from the exhaust but it does not over heat.
The machanic is not sure which it is.

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

I have a 96 honda civic ex, I thought I had a blown head gasket cause I am loosing coolant and it is in the oil. The guy I bought the car from told me he changed the head gasket. I took the head off and the gasket was in good condition. Why would I still be loosing coolant and the oil is cream with coolant in it? I dont kno if he had the head re surfaced. Would that cause coolant to go in the oil? Also I dont have any white smoke comming out of the exhaust or the car running rough. Thank you.

Hi there,

A leaking head gasket may not always be that visible, but with what you have water in the coolant I would be checking for a cracked head.
