The cover will need to be removed prepared for the new seal & re-sealed. When you look at the gasket set you'll need for the job, you will see the seals that keep oil from leaking in around the plug area. You'll also want to check & make sure you don't have back pressure coming from a converter that is going bad or has passed that point already, that's a major cause of seals to leak, that and the heat in the head of the engine caused by the exhaust blockage.

Good luck.

SOURCE: i have an oil leak in a spark plug chamber how do is fix it

depends where the oil came from.of it has leaked down from a valve cover gasket,that is not hard to fix.if it a leaking valve seal that is expensive and if the head gasket is leaking,expensive.look at the outside edge of the valve cover,and check the edge for oil.if there is alot of oil,by the time the plug is unscrewed oil can go inside.the oil would burn off,so if there is oil inside it is dripping down probably from a valve seal.take off the valve cover and inspect the seals they are probably no good.there are 2 seal sets,one is in the valve cover,and that results in oil on the outside of the plug,and the actual valve seal which results in oil in the inside of the engine.

SOURCE: 1999 Chrysler Sebring Coupe 2.5 oil in spark plug

It is possible the tubes are leaking at the bottom but highly unlikely. There is next to 0 oil pressure in that area so the tubes would actually drain if leaking. I would start with the tube seals and gaskets as you have already planned and check it again later down the road like at the next oil change interval. You're on the right track for the repair, just be patient with the intake plenum and you'll do fine.

SOURCE: ON 2002 ALTIMA 2.5 I FOUND OIL

I would try snugging down all the valve cover bolts before replacing anything. A valve cover gasket kit should have the grommets and gaskets necessary to repair this if you find no loose bolts.

Yes, you need a Rocker cover (valve cover) Gasket kit. Remove the valve cover, remove all old O-rings and cover gasket, clean grooves and mating surfaces without gouging or scratching them, put the new gaskets on as per factory recommendations, tighten to the proper torque and you're done. The spark plug holes in the cover are part of the valve cover gasket kit. Any Napa, Car Quest, Pep Boys, Auto Zone will have it.

Changed spark plugs on a 2004 mazda found oil in the pistons #4#3#2#1 was no oil in it


You didn't find oil in the pistons, you found oil in the spark plug tubes. This is fairly common on older engines. Over time the seals in the valve cover begin to leak around the spark plug tubes. Oil then works it's way into the tube and settles in the bottom.

There is an easy fix. Simply replace the valve cover gasket.

Oil is coming out top of moter where oilsendingunitis


If you are referring to tubes as the tube where the spark plugs are installed then you probably have worn out gaskets at the base of the tubes. If you pull the spark plug wire out and remove a spark plug, you'll probably find the plug is soaked in oil. I suspect you'll have to remove the valve cover to replace these gaskets/seals.

What causes engine oil to leak into spark plugs holes?



  • Your spark plug tubes are leaking. The spark plug tubes are set in the valve cover, where the plugs set. It's an easy fix, I recommend a set of spark plug tubes that come with a valve cover gasket. Pull the valve cover and swap the gasket and spark plug tubes, problem solved. Take you maybe 30 minutes to finish the job. I recommend at least replacing the plug that was getting oil all over it. At least wipe it down real well and let it dry good. Common problem, easy fix.

Cause of oil in sparkplug tube?


1.your valve cover's spark plug chamber seal is leaking. Which requires removing the valve covers and replacing the gaskets and seals. 2. Excessive oil spills on to the valve cover and ignition coils when adding oil.

**This excess oil on the plug boots can cause the coils to short and eventually fail.

Spark Plugs


The oil on the spark plug usually comes from the valve cover seal or the spark plug tube. The valve cover seals to the tube and the tube seals to the head. The tube is usually a tight fit in to the head with a little sealant. The tubes can be purchased at the chrysler dealer or possibly at a local parts store. As for the red fluid,it is automatic transmission fliud . It is used in the manual transmission as well as the power steering system. You could have an axle seal leak, transmission shifter seal leak, power steering seal leak, depending on which side of the vehicle is wet.

Oil in the spark plug tubes. engine misses when at an idle.


You probably have a leaking valve cover gasket causing the leaking oil to collect in the spark plug tubes.
The miss fire is probably caused by the HT in the plug lead shorting through the oil and causing a weak spark.
Clean all the oil out and track down the leak.

Oil leak


That is an overhead valve engine and there are seals around the tubes that surround the spark plugs and they tend to dry out and leak after awhile.

Recommend getting a valve cover gasket kit and replace the valve cover and Spark plug tube gromments
