Oil inside of were my spark plugs go?

I have a 99 eclipse GS and I have oil inside of were my spark plugs go and i have to replace my valve cover gaskets and what i wanted to know is, if i got oil inside of my spark plugs and inside of the spark plug boot, is that bad and if so how bad and what can i do to fix it?Oil inside of were my spark plugs go?Assuming it's a 1999 Mitsubishi Eclipse 2.0L MFI DOHC

it sounds like the spark plug tube seals are leaking.

AZ lists a Felpro VS50455R gasket set ($18) w/the description

%26quot;With spark plug tube seals; Permadry molded rubber gasket included.%26quot;

Proper installation of this set

(ie: clean all gasket surfaces so they're clean enough to eat off of)

will prolly fix this common, minor, easy correctable problem.



Spark plugs aren't usually hurt by being submerged in oil but it's a moot point as we change them since they'll be removed during the gasket/seal replacement job.



Plug wire boots may be damaged by the oil. Only inspection will tell. Damage includes swelling, being softer than usual

Clean the spark plug wire boots by spraying carb cleaner on and in them.

It's best to not soak/immerse them in any solvent.

The short period of time the carb cleaner is in contact w/the boots/wires will not hurt a quality wire set.

If there is damage done, it's prolly best to replace them anyway.



DO NOT ALLOW THE OIL TO DRAIN INTO THE CYLINDERS

unless you know there is no dirt/grit in it... and I mean 110% sure.

That makes about as much sense as running w/o an air filter element.



Using a little patience,

some carb cleaner or laquer thinner,

decent rags or paper towels and

an air blow gun

one can have the wells clean and spotless in short order.

This plus blowing off the engine, engine compartment and underside of the hood along w/other clean work practices will help keep the dirt/grit from the inside of the engine where it doesn't belong.



It pays to spend the time and

do a repair correctly the first time

regardless if one is a DYIer or a flat rate mechanic.Oil inside of were my spark plugs go?Find a good mechanic and quick.Oil inside of were my spark plugs go?Sounds like the valve pan cover gaskets are leaking and the oil is running down the side of the head and into the area of the sparkplugs.Pretty common for this kind of problem.Plus the age of the engine that i'm assuming is over 100kOil inside of were my spark plugs go?Get the engine properly tuned. It is giving excess oil to spark plugs that can't be burnt properly. This affects the mileage also.Oil inside of were my spark plugs go?Your on the right track. The oil on the plugs and boots are coming from the valve cover gasket. Change it and you will have no more leaks.Oil inside of were my spark plugs go?There are separate seals/o-rings used to seal the holes where the spark plugs go through the rocker cover and into the head.

Just replace the valve cover gasket and the four spark plug seals.Oil inside of were my spark plugs go?you'll just burn oil for a Little while. see lots of smoke from exhaust.Oil inside of were my spark plugs go?After replacing the cover gaskets, if you've slopped oil all over everything (I think this is what you're saying) you can remove it with some engine degreaser and water.



don't leave oil on the plug wires or boots as it will ruin the rubber after a few months and they will need to be replaced.Oil inside of were my spark plugs go?Better start looking for another car.Oil inside of were my spark plugs go?It will ground out your spark plug wires and smell bad when the motor is running.



It's not that bad of a problem. You can wipe the area out with a soft rag doused with some WD-40 after you get done fixing the oil leaks. what doesn't wipe off will boil off when you run the engine. No Problem.Oil inside of were my spark plugs go?It sounds like the valve cover gasket, which you are replacing, is leaking and getting oil on the plugs and wires. The wires should be replaced and the plugs removed and the oil cleaned off. That should solve the problem.Oil inside of were my spark plugs go?clean the spark plug boots and spark plugs off and wipe the oil off of everything. Remove your spark plugs to wipe them off. This will allow the oil in the spark plug hole to drain into the motor. (this wont hurt the motor as long as the oil isnt lots and lots of oil)

Then replace the valve cover gaskets and spark plug tube seals! If you dont have any missfires now you are probably ok!Oil inside of were my spark plugs go?I assume this is a DOHC motor which means that the spark plugs are in the middle of the valve cover. This is a VERY common problem with these cars. The only real damage it causes is it can destroy the spark plug wires and cause a misfire which is bad for the engine. I would change this as soon as you can. Pull the plug when you change the gasket to let the oil drain into the cylinder and if your going to change the plugs at the same time I would recommend putting the old plug back in the cylinders that had the oil filled in them and run the car for a couple of minutes until the oil burns out of the cylinder then put the new plug in so you don't oil foul your new plugs. You should probably replace the wires if they feel weak or have been exposed to the oil for a long period of time. Make sure you replace the tube seals some valve cover gaskets don't come with them this is what is leaking the oil into those holes.Oil inside of were my spark plugs go?Changing the valve cover will prevent future oil from getting in spark plug holes, but the oil thats already in there is conductive to the spark coming from your wires and could cause a skip or miss later. While your changing the valve cover, pull the plugs and let the oil down in there drain into the hole. Clean the plugs and plug wire boots good with brake cleaner, they'll dry on there own as the cleaner evaporates. After you put it back together and crank it up, it will smoke like hell, but that is the plugs burning off the oil you let in the hole. Then your good to go.
