SPARK PLUGS GASKETS ? IS THERE SUCH A THING

enduring_soul · 09-28-07, 11:47 PM

so i went in yesterday to get my spark plugs changed cuz i started noticing my engine seemed to be choking at 1500 to 2000 rpm. The guy changed them and told me that there is oil leaking into the sparkplugs, apprently i have to change the spark plug gaskets. As far as i know i never heard of gaskets for spark plugs but anywho i live in toronto so i went down to this store called autospot and asked them for a spark plug gasket kit they gave me the most puzzled look. They were like valve cover gasket ? so ya is there such a thing as spark plug gasket is that even what its called or was the mechanic refering to the coils? and how much is it gonna cost me ? another thing is that i am guessing this is the reason y i am getting bad gas mileage. i usually only get like 10 km out of 1 liter of gas.

There is the spark plug o-ring.

I was talking to kenso and he told me that part hardly goes out unless the engine was rebuilt and the mechanic didn't replace the o-rings.

I have the same problem. there is a small puddle of oil in every spark plug tube. I'm replacing the valve cover gasket that should take care of the problem. If not, I'm going to replace the spark plug o-rings.

probably talking about the o-ring.. you have to take off the valve cover and theres o shaped rings in the hole where the spark plugs go... it stops the oil in the head from getting onto the spark plug... the valve cover gasket is the gasket thats on the outside of the cover connecting it to the heads....

Acura refers to them as "rubber seals". I would ask for: "cylinder head cover rubber seals".

They are also called "tube seals" and should be part of the valve cover gasket set.

How difficult are these to replace, I changed the spark plugs and I noticed some oil settled by where the washer is on 2 plugs.

but all in all it is a spark plug gasket. it goes btwn the valve cover and head, in the tube that the spark plug goes down in.

It IS common for those to fail over time.

usually valve cover gasket kits already come with these, as u might as well replace it if u have the valve cover off, works the other way, if take the valve cover off to replace the spark plug gasket, then u might as well replace the valve cover gasket.

Just to clarify, there are 2 different seals that can leak. The tube seals that fit into the valve cover and commonly leak. There are also o-rings farther down inside the tube that don't normally leak. These o-rings fit between the rocker arm assemblies and the head itself. Generally, replacing the tube seals fixes the problem.

Thanks for the clarification. I replaced my valve cover seal about a year ago and i had oil in my passenger side cylinders on this last tune-up. well i figured this, and I know this is like - very wrong and lazy of me, but I figured why not put sealant around the ring where oil could be leaking from. . . like actually coat the place where oil could leak with gasket sealant? what are some risks involved with doing this?

do it right, or dont do it at all.

ari_one · 12-11-07, 05:20 PM

The problem with using gasket sealant or something else is that it will at some point fall off and when it does it will fall into the cylinder via the spark plug hole when you remove the spark plug. Not to mention what it may do sitting on top of the hot spark plug!

yeah i paid for it. . . 3 days after i applied that stuff, my car left me high and dry on the freeway. . . .gasoline spewed out all over my header and i lost quite a bit of oil. . . i had her towed, cleaned out that crap, replaced the gaskets with felpro rings and the black gasket sealant like i was supposed to and now she runs better than ever. lesson learned.

To replace the o-rings between the rocker arm assemblies and the head, how do you do it? Just remove the rocker arms, replace the seals, and bolt the rocker arms back down? Or is it more complicated? I haven't pulled my valve cover to look yet, but theres over an inch of standing oil in two of my spark plug cylinders.

The o-rings are not your problem. Listen to Kenso and replace the tube seals and the valve cover gaskets at the same time and your problem will be solved.

Ken may know more about these cars than anyone walking the planet other than Christan, Pete, Diaz & MikeD so you n00bs need to perk up & listen when they speak about a mechanical issue.

its been about almost months since i replaced the orings and the valve cover gasket my car has returned to its rough driving state and i can feel the throttle being all rough and i probably have to change the spark plugs again cuz the engine chokes at 1200 rpm. As well as my engine seems to consume a lot more engine oil i am not sure whats causing it but could it be i have a head gasket leak ? my temp gauge doesnt go up and down neither does my rpm gauge what could be causing the engine to burn more oil ?
