Spark plug in water

[Odwa_M]

Hi Guys

I need some help with regards to my car, you have always pointed me in the right direction in the past.

Yesterday I noticed a slight misfiring, rough idling and loss of power. I got home, decided to look out for the common issues, oil and stuff. Oil seems to be fine, no water-oil mix or whatsoever.

This is where it gets interesting, my spark plugs are in a hollow position. I took the lead cables leading to spark plugs out and noticed some water in the left one, all other three were dry and normal.

I drained the water, put the lead cables back and started the car, car idles normal and no rough idling.

I have been trying to figure out how the water got in there,but can't seem to get it. There is a cover that you need to remove first to get to the plugs.

My question is, could this be a leak of some sort from underneath where the plugs fit in? Could it be a a blown gasket?

TIA

Next time, see if the water smells of anything like coolant, or has a colouring to it. Might provide a clue.

Could just be dew/condensation?

Have you cleaned your car's engine recently?

No, careful not to do it myself.

I doubt it, dew/condensation would not fill it up till the entire plug is not visible.

So its a block where the sparkplug effectively sits inside an open ended cylinder or pocket

Is it leaking? Why is it only affecting one out of the four plugs?

I am asking to establish what car this is.. so that I can visualize the block and tell you if it could be a water leak or not.
I have only ever dealt with one case where the plug became hollow and some oil was present in the sparkplug recess.

Seeing your profile says you're in Strand, we had a lot of rain yesterday over the peninsula, so its possible you got water in under the cover, somehow

I doubt it's an engine leak. There's no coolant channels in the tappet cover/space, which is what surrounds the spark plug in most cases.

That's what I thought too...

Depends on the car.

I know BMW engines to have an issue with a head seal after an extended time where cooling fluid/oil will "sweat" out of the head. I had to have my seal/gasket replaced a few months ago. Common issue on the E90/91 engines.

The vehicle is a Hyundai Getz, I also thought about the rain. I opened the bonnet, I couldn't see how the water could possible land there.

Is this your engine? is the spark plug with water the one closest to what looks like the thermostat housing?

Your plug lead may not be sealing the plug well properly causing water to seep into the plug well properly.

Time for a new set of leads.

I don't think it is that type, it is not the sealing type like the ones on DOHC engines it is on the side and debris and stuff often find its way there. My Corsa is the same.

 

[Spliffcat]

There is water going from your CDI unit through your spark plug leads this is to keep the spark plugs cool.

Nope not possible.

Check your coolant system is not leaking anywhere

Head gasket leaking most probably

I have the same problem exactly .. and also using a Getz. Rained heavily and the next day, noticed misfiring and loss of power.
Quick one, how did you drain the water?

Stroll down to your local China/Pakistan supermarket and get this, improvise and make it work.

The positioning of the spark plugs make it easy for water to splash into the holes. But it's hot there and the water is supposed to burn off from the heat generated by the exhaust before it finds its way into the cylinder.

Design a shield and use it to cover that area, make sure it's secured.
