Hey guys and gals, hows everyone tonight? I need some help with my car, its been fouling out plugs.
First a little info: i had the head rebuilt in 07 and the bottom end rebuild in 08. Maybe 10k miles on it since then though. Ever since a little after the rebuild the falcon has burnt about a 1/2 quart every 3000 miles. I always thought that the oil was being burned in such small amounts that the plugs were not being effected because i would always pull the #1 plug and it always looked great (should have checked them all i realize now.) A month ago i went on a little road trip with a friend and developed a misfire in one cylinder an hour out. We turned around and made it home. I decided to pull the plugs and see if anything was out of the ordinary and why i lost a cylinder. And i found the #4 plug like this. This is the plug that stopped working. On a side note, the cheap autolite plugs rock! The misfire was not constant, so this plug was sparking still, just not every time.
Its not one cylinder that is burning oil though... #1 cylinder is perfect, #2 burns just a little oil and then it gets worse and worse the farther back you go, except #4 is the worst. What would cause almost all the cylinders to start burning oil and not just one?
I dont know if its rings or valve seals yet. Tomorrow im going to do a leak down test (thats what its called?) to see if its the rings. Is there a better way to see where the oil is leaking from? What else can i do? Also, is there anywhere else oil can get in from, or does it have to be either rings or valve seals?
Thanks everyone.
