About 2 weeks ago, my 87 DX Accord engine (240,000 mi) severely overheated (temp
gauge red-lined) and the engine stopped. Car sat at the curb over night. Had the
towed to a local garage the next morning. When they went to look at it they
1. The car started right up (and even called me to ask why did I bring the car
2. Added 1 gallon on water to the radiator.
3. Did a pressure check on the cooling system and saw no indication of leaks.
They said due to the overheating, the compression on the engine is probably
gas mileage will be less.
I've changed the oil and filter.
But, in the intervening 2 weeks, here's what I noticed:
1. Gas mileage seems to have gone from about 25 to 34 mpg.
2. The values (which previously rattled because they were loose), now are
3. The engine runs smoothly and quietly, even uphill, under load.
So, is the surprising improvement only temporary and the engine will totally die
the not-too-distant future, or have I someone managed to overheat the engine
to compensate for 240,000 miles of wear but not damage it, as it nor seems to
almost as new????
I love the car and thought I had destroyed it, but now I wonder and ask you for
sage advice / opinions.
