"hardly ever get that on a honda - pressure leakage from the cylinders
is confined to the water jacket, and the oil passages are well sealed so no coolant gets into the oil. *commonest symptom is excess pressure in the coolant." Jim, thanks. I do get excess pressure in the coolant. So i really have a failed cylinder head? The cylinder head have been refaced already since i had the car overheated a year ago. Thank you. |

Jim, again thank you very much for sharing your thoughts.
I've been asking around here regarding buying a surplus cylinder head. Suppliers here in our country confirm that there are available surplus cylinder made from Japan. If I have to convert it to dollar, the cost of the cylinder head including the cam and rocker arms would only be $340 - $360 (i am from asia). Do you think this is worth buying? I mean it's cheaper than buying a new or low mileage engine but can i similarly trust the head's quality? Just last weekend, i approached a shop (200kms away from us) that specializes in HONDA engines to do all test to check why I have difficulty starting when the engine is hot. They found out the following: 1.0 I have small leaks on my radiator. (this has been repaired today) 2.0 They found that two of my four cylinders have low compression - position 2 and 3. Position 1 and 4 is ok according to them. I also mentioned I overheated the car and they recommended an overhaul - to see if my cylinder head is warped and how the pistons conditions are. So I see that I don't just need a cylinder head replacement but probably piston sets for the two cylinders having low compression? Would I still need the block also replaced aside from the cylinder head? The local shop which i approached told me it would still be okay to run the car despite the leaking radiator and low compression engine. Unfortunately after coming out from the shop and after travelling about 130kms going back home, the oil pressure and the battery warning lights flashed telling me there's something wrong with the engine. It happened as I go downhill after going through uphill. The WORST thing that happened to my automatic car when the lights flashed was that the breaks has been disabled and I could no longer use the breaks. I used the handbreak instead to stop the car. It was almost an ACCIDENT... Again, thank you very much. I really appreciate all the thoughts you have today. I think this is the price of my limited knowledge on engines...Good thing there are forums like this to help me understand. JD |

I have been starting this car with the gas PEDAL all the way to the floor and it helps the engine start (this is only when the engine is hot to start the car). Where can I find the O2 sensor if thats the problem??? I have a lower gas mileage these days... Isn't this related to the overheating problem I have beed discussing? Thank you very much also for your thoughts. JD |

If that's the case, then yes it's related When the O2 sensor fails, it defaults the ECU to command a wet mixture as a fail-safe measure, cause a dry mixture will overheat the engine instantly. That allows you to continue driving between repairs. The thing is, it may not throw a code, or if it does, the code may not be reproduced after you reset the ECU. Now, a wet mixture is a burden to the cat converter. If such condition persists for a certain period of time, then the cat will become clogged, and when that happen, the headers go red-hot and overload the cooling system. Oh boy, you just open a full can or worms... lol |

I had the overheating a year ago. I don't have any clue actually if
the flashing of the oil pressure and battery lights are symptoms of overheating now but according to the technician who helped tow the car, it was due to overheating. Here's the big BUT: the temperature gauge DID not rose to the maximum indicating that i really have the problem of overheating. The car's engine just turned off after flashing the two lights - oil pressure and battery lights...What is this indication? Overheating or O2 sensor failure? I have difficulty understanding if this is overheating since I have still lots of water remaining in the radiator (about 3 liters left and 1 liter was gone due to the small leaks). Probably the engine turned off because there's just too much air pressure already in the cooling system? How about head gasket failure? When the two lights are on, what happened is that the brakes and gas pedals are disabled making it difficult to stop the car using its own brake. I have to use the parking or hand brake to stop the car. JD |

I don't know about now, but a while back folks in Asia lived with a blissful ignorance of emission controls in motor vehiles and their ill- effects on the engines when emission components start to fail. Catalytic converter is an ill-conceived idea, if you ask me. It was invented because Detroit was unable to produce fuel efficiency engines. So there came the cat converter as a convenience and a band- aid to gas-guzzling, hot-rod pieces of sh*t. Japanese manufacturers took the cat converter negatively when it was first introduced. But then again, they wanted their cakes in North American market, no? Well, i gutted my Honda cat converter, before it has a chance to f*ck up my ride. Global warming caused by emission? F*ck that bullsh*t. Why did the dinosaurs come to an extinction? They warmed the globe by the emission from their buttholes? haha Anyways, your car is severly overheated. Don't drive it until you fix it!!! |

Hahaha. One more question: Do cars experience OVERHEATING without the
temp gauge RISING to the maximum??? The Civic here I think is just the same with the US versions - VTEC, 16 valve etc... JD |

The same Honda year/model for different markets have the same engine mechanical, the differences are in emission controls. In this case, two mechanically identical engines may be designated two different model names. Check to find out what kind of emission controls your care is equipped with. Now for your question. In most Hondas, the temp gauge sender (seperated from the coolant temp sensor) feeds the gauge on your dash board. It may not function properly, telling you the the engine is cool when it's hot, and vice versa. Not sure about the its location on a 97 Civic But the temp gauge sender usualy has one wire, disconnect this wire from the sender and ground it. Now, insert the key and turn it to ON (II), you should see the gauge at the maximum. If not, replace the sender. And do not leave the wire grounded for more than few seconds or you risk damaging the gauge. Cheers |
