Recently I wanted to replace my spark plugs and realized that the spark plug wells were filled with oil. Looked online and saw that my rocker arm seals were probably the culprit. I ordered a few parts and tackled the job following several written tutorials on this forum and a few videos on youtube. Once done I replaced the spark plugs as well.

I just ran my car and a some white smoke is coming out of the tailpipe. I looked online and it seems everybody has different opinions on what white smoke means: antifreeze (I just added some while doing my repair), oil, steam, transmission fluid. The smoke doesn't smell terribly burnt nor does it smell particularly sweet.

What do you guys think?

 

Just went and tried to rev my engine again but this time no white smoke came out of the exhaust. I hope it's a good sign.

 

A compression test and or a "block check" test can confirm a bad head gasket.....if you are still worried.
