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: Oil in #2 spark plug chamber. How do I fix

This is not good. There are two ways to get oil in your cylinder..best case, valve guides..requiring a head job, worst case, blow by the piston, requiring an overhaul. Wish the news was better. Good Luck! I hope you find this very helpful!

Does anyone know the spark plug wire order on a d15b7


Oil is leaking into your spark plug holes from the valve chamber. It's not a good idea to leave the oil in the spark plug holes, as it can pool high enough to damage the rubber boots of your spark plug wires, will make the plug hole really messy, and it may eventually become a fire hazard. Below is how to fix it.

Honda's preferred spark plug location means that the plugs (and their wires) must pass through deep recesses in the top of the valve covers to get to the combustion chamber. This gives better plug placement in the combustion chamber, and more zoom for your Honda. It creates a small problem though: Under the valve cover, all around the spark plug recesses, is an open space that is constantly being showered with oil, and that oil will get into the spark plug recesses unless something is done to keep it out. Honda does this by sealing any joins between parts with little rubber donuts (AKA "grommets").

The rubber donuts eventually get old and stop sealing, letting oil seep into the spark plug holes and puddle there. The cure is replacement of all four (or six), along with the valve cover gasket itself (themselves) at the same time. It's an easy project for anyone who's done more than just oil changes.

However, there's a fly in the ointment here: Certain Honda engines, specifically the 4-valve-per-cylinder, single-overhead-cam ones (such as the D15B that's used in many Civics), have an additional rubber seal under the one I just mentioned! This one also gets old and starts leaking, but these are a LOT harder to replace! Not a job for a beginner!

NOTE: The rubber parts under discussion here are not actually red and orange, they're black, I just used colors to make it clearer which was what.

Audi a4 19 tdi takes long to start n makes clouds of black smoke what can b da problem


Pull out the spark plugs and check for oil on the spark plugs. If you do have oil on the spark plugs, the valve seals are leaking. The top of the engine has to be taken apart to repair it. If this is not the problem, then the oil rings on the pistons are worn out and leaking oil into the combustion chamber. This is a very expensive repair.

Why is there fuel on my spark plugs.?its an 2.8


I dont know about fuel but if it is actually oil, heres what that can mean. Oil is leaking past the worn valve guides or piston rings into the combustion chamber. Causes hard starting, misfiring, and hesitation. I recommend checking and fixing any problems with the guides or rings and changin the spark plugs once you find the problem. Please let me know if this helps and please rate my response for me. Thank you

Eng. shakes spits/sputters oil in spark plugs


I just had this fixed on my suby today. The cause is that the spark plugs, go through the valve covers on the 2.5 l .When the o rings in the cover go, the result is oil in the spark plugs. The cost of the repair in Canada was about $500 including diagnostics as well as new plugs and wires About 1.5 hours labor and new seals and gaskets. It now runs like new. This is a common problem for this subaru engine as well as for the dodge neon.
