|A hot affair
My 1998 Integra has served me well. A year ago,
a leak in a radiator hose caused the car to overheat
a few times. I kept putting in coolant whenever it
overheated until I realised it was a hose leak, and
got it replaced. Now the car starts and runs well
until it gets hot. Then It starts to misfire and have
very rough idle.
There was grey smoke from the exhaust after
driving for a while. When the car is cold, it runs
well for about 30 minutes before starting to misfire and smoke. I also have to refill the coolant.
It looks like when your car gets overheated, the
head gasket becomes distorted and allows coolant to
leak into the combustion chamber whenever the
engine heats up. When the engine is cold, there is no
expansion of the cylinder head but when the engine
heats up, the expansion allows the leak to occur.
