Where did this oil come from? (outside of spark plugs)

The Rusty Gear · 02-17-2007, 06:30 PM

Changed the spark plugs today and there was some oil just sitting just behind the plug boot. You could see the little puddles when the boots were off. Was there for all 4 plugs, but quite bad on the drivers front one, which partially coated the boot as i pulled it out.

Where the heck could this be coming from?

Thanks,

you have a leak @ the valve cover gaskets-specifically the plug hole seals--you'll need to replaced the valve cover gaskets/plug hole seals/& bolt seals to properly fix this problem. hope this helps. let me know if you've got any other questions.

The Rusty Gear · 02-17-2007, 07:19 PM

Well, if those seals are going, what else is likely to go? ie anything else I should be looking at? I was doing the plugs as part of the 60 000 mi (100 000 km) preventative maintenence.

SubeTek · 02-18-2007, 09:31 PM

not really anything else should need replaced unless you seeing other problems/leaks.

The Rusty Gear · 02-19-2007, 11:06 PM

No other problems so far. Thanks for the advice!

SubeTek · 02-20-2007, 04:23 PM

Glad i could lend a hand.

Rtony103 · 04-09-2007, 06:49 PM

hey i got the same problem... and i just wanted to get some more detail about changing the seals and what exactly it involves... and if its something that i should do like now or if it can wait a while?
thanks

I just had mine done under warranty at 77k miles. Oil soak can ruin plug wires.

wanbol · 01-28-2008, 02:10 AM

Did my plug change last night, and saw some oil on my plugs also in the cylinder on the driver side front...will it be the same problem? But the burn is still ok, just a few wet oil on the threads...and plug is a little black on the rims but burn is fine.

Same problem?

rkramer · 01-28-2008, 09:08 AM

you have to remove the valve cover (fairly easy) and just swap out the rubber seal if that is problem. I've got a write up on here somewhere, search for half moon seal. (that is a different issue, but you have to remove the valve cover to fix it also.)

Acostafan · 01-30-2008, 08:45 PM

Tedious, but easy fix. You will also need some Fujibond for the half moons and key spots by the forward cam caps.

hondabond HT was what worked the best for me. (I had it out at least 4 times trying to get a good seal, the final time I used the hondabond and never had a problem.) You REALLY want an angled wratcheting wrench for this one, trust me!

Acostafan · 01-30-2008, 09:53 PM

Eh, it's just what I call it. I actually used something compatible from Autozone. Worked like a champ. The whole thing was easier for me as I had the engine out when I was building my hybrid. I'm sure it's a little trickier with it in.

LatentWagen · 04-10-2008, 02:51 PM

almost sharted today when i pulled my plugs to install fresh ones and saw oil, good to know it's not the end of the world

anything wrong with drying it up and putting in new plugs? im going to drain the oil and see if i can get the plugs in without fouling them in the process...

Good pictures to give you an idea of what's involved with this job:

They're from a 2000ish RS, so check your part numbers from another source.

Chillun · 04-14-2008, 12:35 AM

Same deal on my 2001 Legacy GTL. The driver side spark plug #4 seal started leaking. The fix is very easy. Thanks for the pics post nardvark. I never could find a torgue spec for the value cover seals until in that post. I'm in the middle of the job right now. (along with a few other oil leak headaches.)

RoadTrippin · 04-24-2008, 11:03 AM

Anyone know where I can get the part # for the 2002 2.5 plug hole seals? Or possibly a website to buy them from, Ive looked around and I cant seem to find them with the description Im using.
