Hi Folks, what is your opinion on the following: Car was totally out of power and I was told it was not firing on one full bank of cylinders.

Got call today to say inlet manifold was removed to access spark plugs which were found to be sitting in (rain) water. I asked how that was possible and I was advised bad design where water had run off the shelve area under the windscreen and filled the plug wells!

I don't know much about how the spark plugs sit, but is this possible?

I don't know the set up of the inlet manifold but if that has water also flowing through it and wasn't sealed properly when the spark plugs were changed a few months ago, then this to me would be a more logical explanation.

Thoughts and comments appreciated.

 

PS - This is for a 2003 S-Type 2.5L Petrol Car

Didn't specify which type of car

It's possible.  

Itd have to be a heavy rainstorm to get to the plugs though  

Do you park under a tree or pressure wash your car?

If they have identified where the water is getting in then you need to look at drain holes being blocked.

it may be worth while taking the scuttle panel off and cleaning them out.

Hi Andy,

 

Car was parked at a friends and I haven't been aware of any massive rainfall or pressure washing. Garage says drains are clear as I did ask that.

Just strange that the whole of that side was not working. Is there any water running through the Inlet manifold that could have leaked onto them?

Thanks

I'm not too clued up on the petrol inlet but I think there is some kind of water passage in them but if that was leaking you'd notice coolant drop and the garage would've said coolant and not rain water. 

 

I've had the inlet off mine to do this job and there was no water around the plugs. The plugs are well protected and the poor design comment is not valid IMHO.
