Haha no prob. Personally I think it was just luck. Diag-ing over the Internet is a bitch to do

Hi, I read all the posts and wondered if you know of other issues that could cause the smoking out of the lower pcv hose? What I can tell you is this;
1. I am on my 20th injector (all 8 changed 2.5 years ago with 150K/Driver's 4 changed 2 months ago when two of four failed)
2. Head gaskets replaced 9 months ago (both sides)
3. Cylinder balance rates are all normal in idle/neutral (+/- 1 from zero)
4. #6 cylinder reads 7-8 in idle/drive, while other cyls read 3-4
5. Smoke puffing out of oil fill when cap is removed
6. losing about a cup of coolant every week
7. Oil is not milky
8. No smoke is coming out of tailpipe
9. Slight knocking (ticking) coming from the driver's bank (not a fuel knock)
10. Using about 2 quarts of oil per 5k miles
11. Engine is not running really rough, but has slight vibration not noticed before.

I'm hoping it is the hold down bolt. Thoughts?

Thanks,
Chris
