Hi All,

Recently, when starting the car, I get a gushing sound of water underneath the car when I press the gas, even slightly and even when the car is stationary!??

Tried to search for possible reasons.. couldnt find anything constructive. Any Ideas?

Thanks

I had the same thing last week.
It's water pooling in the back boxes of the exhausts.
Give it a good long high revving run 40 mins plus should get rid of it.

Maybe a rattling heat shield over the cat too.

Sennas right though, I took the back of teh R26 system off for an upgrade and the rear silencer had ONE PINT of water in it LOL!

Really? wouldnt it evaporate after a long time, given the temp of the exhaust? The water noise is there consistently. Now matter how long Ive driven, if I rev the car, you hear the water gush underneath!

something to do with Coolant? or headgasket?? Havnt noticed any over heating..

When I changed from the OEM manifold and cat I thought my car sounded like I could hear running water. I got used to it.

what does it sound like outside of the car?

Yep, am in no doubt, this time of the year the cold air meets warm exhaust and creates pints of condensation.
U will not get this in warmer weather...

If its constant its more likely to be a rattle from somewhere that just sounds like gushing water.

Unless you have an airlock in the coolant system, but i'f be surprised if that was the noise. Does the heater work ok?

It is definitely water Im hearing.. can't be mistaken for a rattle.

Havnt listened to it from the outside, so cant say how it sounds.

No changes to heating or running temperature.

Guess it might be water in the exhaust..

but sure as hell doesnt sound healthy!

Thanks anyway.

If you try and move the car when parked can you hear it then? Like when you open the door and stand in the sill and jump a bit?
