I changed my rocker cover today which involved removing all the spark plugs (well not the actual plug but the leads), when I pulled out number 2 it was all orange and rusted its made of plastic so it was actually corroded but coated in rust.

I've never notice a problem with the car it doesn't sound like its running on 3 Cylinders or lumpy in any way it never skips a beat but obviously this is a concern to me.

Any advice?

If there's water in the cylinder that points towards the head gasket going.

Strange place to get coolant. If its the head gasket starting to let coolant into the cylinder the only way I can see it getting to the tube is passed the spark plugs threads. Is the spark plug tight in the head? If water was getting into the cylinder the exhaust would contain steam and the coolant level should be dropping.

From the photos I cant see any other signs of coolant, corrosion or mustard looking deposits (emusified oil due to coolant).

I'm not sure how the tube is sealed into the head or if it is possible for water to get passed the base of the tube if the tube is loose.

I dont wish to alarm you but it may be due to a cracked head.

I think this may be one for the font of all knowledge Mr. Relic

it would be a good bet that the engine washed at a time with a power washer and water has gotten into the plug tube
was a common fault on ep3s
if your coolant level isn't going down don't worry

Thanks for the reply's, my bet was that water got into the tube from the top, it doesn't look like it got past the plug, everything is tight and firing on all 4.

I have never used a pressure washer on it but the previous owner or dealer may have, the oil and the rest of the workings under the rocker cover seemed in order (more pics in my build thread) no foaming oil or anything like that I am reasonably happy to leave it be at the moment I cleaned up the lead and replaced it so will check again in a few weeks.

Thanks for all the help, if anyone else has any opinions I would be glad to hear them.

been avoiding it.
I hope...someone cleaned the plug leads with water and shoved them back on.
Hopefully it is the result of one wet lead.
Im kinda hoping its the metal lead tube that has reacted with said wet lead.

If not... Im cringing TBH.

 

[dodger]

Water from cleaning isn't something I've across but on second thoughts it is possible.

Sorry to drop you in it Relic.

 

[Relic]

Its OK mate....I agree with what you said...just exploring other options....

...I would pull that plug out though and check it for cracks.
A perfect burn should give a golden brown residue.
In fact I might consider changing the plugs to be on the safe side.
But I would also be counting the turns it takes to seat that particular plug compared to the rest.

+1 ensure that the plug hole is dry before you crack the plug the last thing you want is water in the bore

The vicinity of the water jacket can cause water leakage if it cracks.
But I dont know what the honda head design is like without cutting a head in half.

This is what dodger is concerned about I think.

I'm not sure exactly where the water jacket is but I just wondered if it was possible for a crack in the head to allow water into the bottom of the plug tube.

Before refitting the plug cap give it a good clean and see what it is like in a couple of weeks and keep an eye on coolant level. If you start to use a lot the time has come for immediate action.

A said above hopefully its water leaking in rather than out,

First thing I would do is clean the coilpacks, replace the plugs and change the coil seals, no.2 on this page

I fitted a new rocker cover so its a different set of seals fitted now, thanks for the links. I did buy that seal pack from eBay, but I couldn't work out how to get the old ones out in order to fit new ones :S

I hope its was just water getting in the top, will check it in a couple of weeks.

Thanks again for the help
