Civic 97 --- "Boiling" sound from the engine --- Please, advise!
Hi everyone,
I'm hearing a strange "boiling" (even a little "hissing") sound from the engine *only* when I accelerate. I hear it much more distinctly in low gears. At first I though something in the AC system was causing it, but even with the AC completely off I hear it distinctly. Is this a problem with one of the belts? After a "visual inspection" of the timing belt it looks very good---no cracks, no excessive wear, the "play" is within limits (according to my Haynes manual). Car info: Civic 97, automatic transmission, 60K. All hoses under the hood are in perfect shape. There are no leaks of any kind. All fluids are in norm. Any insight will be much appreciated! |

It makes that sound when the ignition timing is a teensy bit too advanced. The advance isn't bad enough for knock but it sounds like a pan of water on a hot burner just at the point where tiny steam bubbles are forming and collapsing. Get the knock sensor checked if it has one, otherwise retard the timing just a hair. |

As a continuation of this saga, I went to see my Honda mechanic and---as it always happens---there was NO "boiling" coming from beneath the hood!! He drove my car around the block (and, boy, did he drive it!) but couldn't hear it! I can swear I was was hearing it all the way to the JFK airport yesterday! It's kind of quiet, but discernable. I'm totally puzzled now---if your timing is off, it's off (or am I wrong?) I'm ready to believe that performance of my gets affected by the weather. :) Along these lines, CAN it be related to weather? Could it be something in the cooling system? Not that it's a dry desert here, in NY, but it was much warmer yesterday than it is today. I cheched the pressure cap and it was allright. When you accelerate, the coolant flow should be increasing, right? Is this what I'm hearing? The temperature gauge stays at approximetaly 1/3 all the time, so looks like there's no overheating, and the coolant level is fine, but still.... Oh, also, just recently I replaced the spark plugs with NGK (the ones recommended for my model). The old ones were nice and "clean" which indicated that there was no detonation, oil spilling, grease, or anything. If timing was off, I guess I would've noticed something on the plugs. |

Adjusting the timing just one degree would probably put it solidly into buzzing or silence. I adjusted the timing by ear after I bought my car because it was badly off (18 MPG) and the corrupt dealership I bought it from didn't want to look at it. I've had to retard it slightly a couple of times to compensate for carbon build-up. My car, a 97 HX, doesn't have a knock sensor. |
