So attempted to troubleshoot:
  • popped the vac lines off (that I messed with) and those are not clogged- the 2 on top of the TB
  • disconnected and reconnected the sensors (that I had removed prior to get wiggle room)
  • I've got the harness loom wrapped in gold heat tape- it's not exposed anywhere by feeling around
    • Also started up the car and wiggled it around in case something broke in the bundle)
    • I've been careful to not contort it much
  • popped off the valve cover vent lines- large and small
    • the small spun in place a little - PCV in the gasket (will need a new gasket there I'm sure) but tested the valving of it- blowing sealed it off and sucking lifted the ball (and gave me precious valve cover innard gasses..) - so seems functional and not leaking
    • no clogged hoses
  • checked oil cap again- milky residue is gone this morning- yay!
  • checked the dipstick- no trace of funk there either...measured about over half way on the mark- engine is super cold obvi
  • coolant looked good also- I did put in a little in the reso as it was lower than the "mark" on the bottle
  • I shook all plug wires at the plug side and at the distro- connections good
Started up again and immediate smoke. I let it idle while pluming...shook all the wires and hoses..no change. I cant tell what the smoke smells like...its not sweet like coolant and not oily-like...maybe a combo...but there's lots of it on start up and when adding throttle, theres lot more.

Car is still feeling lobe-ish on idle and on throttle like a misfire- I had cleared codes the other day and they havent presented themselves back yet- also havent run the car too long since. Idle isn't trying to die...its just really rough.

Drove out of my driveway and maybe 500ft down the road...leaving a plume trail...same stuttery idle and throttle sound as I reparked.

Aside from tearing back down the valve cover...anything else I should be paying attention to?

I'm leaving for HI on Saturday so this project may be sitting for a bit..

I think autozone will rent out one of the radiator headgasket testing kits (when you get back from travels)

Crap - I actually have one of those!! Forgot about that kit- thx for the reminder.

I was going to do a compression test when I got back. It just blows my mind that the car was fine (just a #6 misfire) prior..

Will test it out in a few...

I'm going to say inconclusive... but I can't rule it out...

I let it idle a minute and performed the test...directions say 3-5 bulb plumps... I did 5 squeezes- being careful not to introduce lower chamber fluid into upper.. no real change. so squeezed more (10 or so more)..noticed a very minor lightening of the color...so squeezed even more. But color seemed to stay just slightly lighter.

I used this kit on another vehicle before and the fluid turns piss yellow with a gasket failure- I've witnessed it..

I got this result:

So maybe there's a leak?? But it's definitely not bubbling my radiator and not a strong presence...

I’ve posted this pic about 6-9 times but here’s what mine looked like for reference.

Yours looks yellowish to me. If you have time and a kit, send a sample off to blackstone and get your oil analyzed. They’ll be able to tell if there are any traces of coolant in your sample.
