why is there water in combustion chamber?

is there any way to fix it?

Fix what? Didn't determine what(if anything) is 'broke' yet. No answer to my original question.

it also happened to my 95 ford Thunderbird. it only has 31,000 miles. it is a 3.8 v6. 40th anniversary car. it got into the #1 cylinder . on the 97 f150 it is a 4.2 v6. it got into the back cylinders. i changed the rod in it because it was bent. not knowing what caused the problem. other than the water in the cylinder.

Hard to get the full story on line , but what kind of driving conditions?

the f150 was a driver. drove it all the time.. around here it is mostly 65mpg hwy. also we have some mountains & a lot of mountain roads. i replaced the rod before about a year ago it lasted for about 6 months & it happened again. so it has been sitting. the t-bird we just bought it from a local lady. her grandmother just died & it was her car. it sat for the last 4 years cuz of the engine. any more info .. just let me know thank you

Other than hydro-locked from coolant (blown head gasket) , or running through a puddle and water getting past the air filter etc. , I'm at a loss as to why you'd get a bent rod. Need to have an EXPERIENCED local professional (the oldest old man at the oldest independent garage in town type) look at it BEFORE tear-down , if it happens again.

thank you for all your help.
