Hmm... Blue Smoke. I got an automatic DEQ failure yesterday. I didn't even get a chance to pull into the testing bay. I was pulled aside and out of line by a very condescending DEQ employee. In it he pointed out that I had blue smoke emitting from my tail pipe. I hadn't even noticed it until I was idling in line for about 15 minutes. The engine runs clean when I'm on the highway and on the surface roads but when I got home from DEQ last night, I let it idle in the drive way for about 10 minutes and Yes, you can easily see blue smoke.

I did some research on the matter and everything I've read has me thinking that it is the valve seals and valve guides on these new cylinder heads. You know I bought these back in 2009 from clear water cylinder heads but I never removed them out of the packaging until January of 2014. I wouldn't have imagined that could cause bad seals and guides but now I'm not so sure.
