Did you correctly install the four spark plug tube seals, on cleaned tubes, as well when valve cover gasket was installed?
Yeah everything is installed right
The first time I change them. There were 3 spark plugs leaking
Now it's only this one giving me the trouble for the last two times
Thanks again for all your help
Try a little rtv sealant along with the seal.
I was gonna try that next
Would it be the PCV ?
I'm not sure what that is
Thanks
Sounds like the seal just aint doing it's job. Positive Crankcase Ventilation (pcv) valve will not cause your problem!!
Ok cool ill try that
Alot of people were trying to tell me it's inside the engine before I can't see it being that
Just seal up everything good and your problem is fixed!
Okay thanks so much !!
it means that you are getting a blow by in one of your piston rings. It either needs to be replaced or repossitioned. There are two rings around every piston and the opening should be opposite from the other
You should really take this vehicle in to be checked out. Without seeing the vehicle first idea would be valve cover gasket, but a blocked PCV could also cause that problem. These can be diagnosed.
the valve cover gasket needs to be replaced. You know where you put your spark plugs, there are 4 individual seals for each of the ports the spark plugs go to under the cover. If that isn't it then you have a blow by issue, meaning the oil is getting passed the piston rings
