Error Code P0315 on 2007 Chevy Aveo

Just drive it and the oil will burn off.

Replace the valve cover gasket and spark plug tube O-r4ings

As far as I know spark plugs only have a metal type washer to seal, and there is no other oil seal needed. I have know oil to leak from rocker cover and fill spark plug wells, but tis also often covers engine. Burning oil smell couldbe from oil going onto the outside of hot engine. Check oil loss via dip stick. Clean all oil from outside engine to find out sites of leaks. Hope this helps.

Spark plug tube seals are leaking and need replaced along with the valve cover gasket. Any parts store should be able to get them for you. if left unrepaired it will eventually cause misfiring.

this sounds like the engine could have some bad valve guide seals allowing oil to be pumped into the combustion chamber of the engine, or you could have some broken pistion rings in the cylinders, i would get the vehichle checked out soon for this problem.

The oil is probably leaking into the spark plug wells from the seals at the bottom of the pipes that constitute the wells. The wells may pull out with the plugs removed and have a seal at the top, but the bottom of the pipes may have been damaged if they are held in place by the plugs. Another method is to hold the pipes in place in the head with 'o' ring seals and these may have developed a leak, allowing oil from the tappet cover to get into the plug well.

Yes. The valve covers have seals that seal around the spark plug tubes where the plug wires go down through the valve cover. A valve cover set should come with the spark plug tube seals. This is a common problem with Honda. I also recommend replacing the plug wires because the rubber boot can get saturated with oil and cause a misfire. Sometimes it may look like the boot is clean when you wipe it off, but the oil is still in the pores and can cause the boot to allow the spark to arc over to the spark plug tube. Most of the time the ceramic on the plugs gets messed up also. This can also cause a misfire. If the plugs have any brown or black discoloration that does not easily wipe off with a rag, then I also recommend replacing the plugs. The discoloration is caused by carbon. Carbon is highly electrically conductive. This will allow the spark to travel down the side of the ceramic to the metal base of the spark plug.

You have oil in the plug holes because the seals that are supposed to keep oil out are leaking-you need to remove the valve cover to replace them.

Hello, this is caused by a valve cover leaking oil. you will need to replace the valve cover gasket to correct this concern.

The valve cover has rubber o-ring seals that fit into the valve cover and seal oil out of the spark plug wells. Over time, they get hard and shrink, allowing oil to enter the plug wells from the top of the engine. You need to remove the valve cover and replace the valve cover gasket and o-ring seals. The seals should come with the valve cover gasket set.

Hope this helps,
