Hello all.
2004 echo, 109,000 km. P0301 came up and upon investigation I discovered that my no.1 spark plug well was filled with what I believe to be coolant. The top of the valve cover (where the coil packs are seated) was bone dry. The oil, from what I can see on the dip stick looks ok - I intend to replace to investigate further. Coolant is low. Spark plug wells for cylinders 2 - 4 are ok.

Does anyone have an idea as to what may have caused this and have suggestions on what could be done to troubleshoot and to repair?

Thanks,
George

I once had a 1993 Ford Escort. Something was wrong and I rebuilt the engine along with a better man. Eventually this didn't work either because the engine block had cracked and leaked out coolant along with exhaust. Does your car stinky but you winky.

Thanks for the replies.
So far dried spark plug cavity, replaced all spark plugs and changed oil and filter. Oil looked normal (no sludge or milkiness). Car runs like before. I've been driving for a few days now with no codes comming up and no water or otherwize moisture noticed in plug well. Will continue to monitor and investigate.

What has the result been since you changed the plugs? I am suffering a #1 cylinder miss, and changed the plugs. #1 appeared to be damp. All was good for a few weeks, and this morning it appeared to be missing again.

I haven't had time to really look into it, but for those in the know, is this a sign of a head gasket going, or something less serious?

Thanks.

ASC08:
I've had no problems whatsoever. Since I dried the well, and replaced the spark plugs, I checked periodically the spark plug well and it has since always been dry as a bone. I keep checking periodically. Last check, just a few days ago actually, there was rain water caught in my bug deflector that ended up falling near the oil fill port. I realised that this little bit of water then got traped on top of the valve cover, adjacent to the coil packs.

My theory is that when i washed the engine compartment last fall, water got caught on the valve cover and made its way based the coil pack boot. After a while, that water made its way past the spark plug and created a fouling condition. I keep my fingers crossed that that is what it was. I guess I'll see over next winter when the conditions are better duplicated.

Hello,
12-3-2015

I have a 2002 Echo. Bought used with 134,000 miles. Car began to misfire, chug on take off. Resolved at higher speed, became worse over a few days.


Took off #1 coil pack and looked into spark plug well. Wet with lots of rust on and around spark plug. Cleaned around plug and dried well. Removed spark plug, very corroded and rusty??? Unknown how long plug exposed to water???? Judging from the rust probably a long time. All other spark plugs and wells --no rust--clean.

Replaced all Denso plugs, --may have been the original OEM plugs?

Runs perfectly now with NGk iridium plugs.

Where did the wetness come from? Did not appear to be coolant. Condensation?? Why just on cylinder #1 ???

One thing I really want to see on a used car is an engine covered with clean grime appropriate for the miles. Rag-cleaned valve cover and exposed surfaces is OK. Evidence of pressure washing is a deal breaker.

It's a design flaw on these cars. The belt can sling water up and get water down in the spark plug tube. It's fairly common, it happens on mine.

Confused

Hello. I own a 2000 Toyota Echo, that I purchased used about 6 yrs ago. I have not a single problem with this car, until recently when I discovered water in the #1 spark plug well. I'm confused about why all of a sudden this well is taking on water. I have removed the plug, dried the well and replaced the plug with a new one three times within a month. I have even purchased and installed a Coil On-Plug Insulator kit, thinking maybe the rubber seal was worn out, but even that hasn't helped. I live in Florida, it's been an unusually wetter summer than normal, but even at that, it has its rainy seasons here, so I have trouble believing it water being thrown up by my belt. If that was the case I would believe that it would have happened from the start. I do have a theory that it's tied into my A/C somehow. I'm not big on using my A/C, but lately, I have had to use it more often, when my brother is riding with me. He suffers from COPD and has trouble breathing when it's hot and humid. I don't like using the A/C, because it seems to put a terrible bind on the car. After replacing the spark plug for the third time today, we drove to Alabama, which is about 40 mins. from where we live. We ran the A/C on the trip up. The car ran great when we first started out, but by the time we got to AL it was starting to miss again. Did not run A/C on the return trip, thank goodness it had clouded over. Car still has a miss. Was unable to check if the well had water in it, since it was late when we got back, but will check tomorrow. Please any suggestion would be helpful. I've read all the remarks on here, but none seem to be helping my situation. Thank you for your time.

I no longer have my ECHO, but if I recall, there was a problem with the gasket on the hood, up by the firewall. It would let rain down on the engine and it would get in the spark plug tube. I re-positioned it and all was well.

Guess I need to check my #1 spark plug. Might as well put some iridiums in while I'm there. Maybe do a valve cover gasket since there is overlapping work involved.

Thank you, asc08, for that informative input. The rubber gasket on my car is very worn out. Repositioning it is not an option. Not sure if I can replace it, will be checking on that, but was wondering if I could use some silicone to hold it in place and cover the gaps. I know it gets hot under the hood, so not sure if that's what I need to use or something else.

I checked mine this morning, #1 was rusty, the rest were fine. They all showed wear commensurate with 30k+ miles and were not iridium, so I grabbed 4 iridiums and installed them. I always break them loose and the blow out the tube with compressed air, to get the crap out before removing them completely. #1 was a cloud of dust. No oil leaking into any of the tubes so I'll let the VCG go a while longer. Car ran better, filled the tank, and drove to my buddies shop. When I got home I had done 33 miles at 65 MPG! The tank refill came to 51.1 MPG regular gas at Costco for $2.499 a gallon. less than 5 cents a mile for 386 miles, $18.80.

I have been dealing with this issue for at least 5 years now. Water in the #1 spark plug hole, causing misfires. I finally discovered last year that water was leaking past the windshield washer nozzle assembly and onto the top of the plastic cover over the spark plugs. It would work its way down past the oil filler cap. For some reason, the rubber gasket doesn't properly seal the spark plug #1 well (I can spin it when everything is properly tightened). I tried moving one from one of the other spark plugs, but found that while they seal fine at #2, #3, and #4, they won't seal at #1. Something may not be machined correctly at the #1 well. I wouldn't recommend using silicone to seal anything. Silicone off-gases, and it the vapors are pulled into the air-fuel mix, the oxygen sensor will be damaged. I sealed the gap around the windshield washer nozzle assembly with Captain Tolley's Creeping Crack Cure. That solved the problem until a couple of months ago. (Incidentally, I kept getting corrosion at the battery. I sealed the washer nozzle assembly above the battery, and haven't had any corrosion since.) I found that with my latest problem, the rubber gasket that seals the engine compartment to the hood was out of place, allowing water to once again get onto the plastic cover. I fixed that today, and have placed a sheet of plastic over the hard plastic to try to keep water out. Ultimately, it would probably be better to find a better gasket to use at well #1. I may look for some thick rubber sheeting that I can cut to size in place of the current gasket.

I have the same problem, coolant in #1 spark plug tube

Hello,

I came across this thread trying to research the cause of some coolant/water I found in my #1 spark plug tube on my 2000 Echo with 226,000 miles and a 1.5 engine. I found this thread directly relevant since the original poster said his car was also an Echo and the #1 spark plug tube in in his car also had coolant/moisture. My car had been running well until, in recent weeks, it would once in great while momentarily miss and then return to normal for many days. However, this week, it suddenly started missing and stumbling consistently after the engine had been running for 15 or so minutes. Yesterday, I removed the spark plugs to check their condition and they all looked fine, but I noticed some coolant and water on the inner portion of the #1 spark plug coil and the boot that fits onto the plug itself. The spark plug tube was also wet, but there was no moisture or coolant on the spark plug tip that goes into the cylinder. The amount of coolant in the tube was not a lot, but it immediately caught my eye when I removed the boot and saw many water droplets on the surfaces, something I had never seen before. The other spark plug tubes had no moisture. There is no white smoke from the tailpipe that would indicate a blown head gasket and the oil on the dipstick looks normal, no foaming. I am wondering if the cause is one of the following: head or block cracked; maybe a blown head gasket; or perhaps a leak in the intake manifold. I intend to start this weekend by removing the intake manifold to inspect it, possibly replace the gasket if there is evidence of a leak. Any thoughts or comments about your experiences would be appreciated.

I have the same problem. 02 echo. 210xxx kms. Several times either cylinder 1 or 2 have had water and started misfiring. At first I thought it was an injection issue until i looked at the plugs and they were filled with water. Im not 100% on this, but if you do a compression test I think that will tell you if your head gasket is ok. Mine have only had water no oil or coolant. First noticed it about a year ago and I sopped the water up with shop towels. Now Im on a road trip and it started again. Im just going to monitor it and hope for the best. Not sure what’s causing it but if I figure it out ill post it here. Seems like a reoccurring theme.

Hello.
Had this issue on an XB, and on an Echo or two. All cases for me turned out to be from outside sources. I went through a car wash once and it happened in the car wash to my XB.
I used to run them with the engine cover off, but it seems to cause this issue more readily.

I had the same problem once - water in the number 1 plug well. Misfired badly. Got the water out. Changed the coil pack and plug. It was fine after that. No more problems.
