Need some help, a while back, my cel came on, and of course i go and get one of those free diagnostics at autozone. i get code number P0432, and assume that it is something that can wait for a little while. Well, today, i just swapped out my spark plugs and changed the air filter, but when i changed the spark plugs, i had four that had oil on the threading of the plugs, and two that were completely normal. any ideas of what this could indicate?

 

:Main catalyst efficiency below threshold (bank 2)

 

yes, i know what the code means, but ime wondering if that has anything to do with why the spark plugs are oily.

 

lol no spark bad spark plugs would make your engine stumble

 

ahhh, ok. i was afraid that i had blown a head gasket somehow.

 

if you blew a head gasket your car will smoke and be using alot of oil

 

It's a valve cover gasket. Ours have 2 pieces, mine also leaked around the spark plugs. There is a DIY on passat forum

depends if he has a 1.8t or a 2.8

 

it's a 2.8, not using much oil at all, and no excessive or blue smoke coming out of the exhaust. it has been starting hard this winter though

 

well just change the plugs use ngk's by what i understand people on the fourms say the ngk's work better than the bosche and im running the bosche with no issue's when you change the plugs just check back in a few 1000 miles and see what you get but i wouldnt worry about that at all
