The nasty and dreaded valley pan and coolant transfer pipe - would have required engine removal to replace. Now, an expandable pipe is available. Cut the old one in half, remove, and install new pipe. Tighten as directed. Install new valley pan and gasket...sounds easy? That bastard child of an intake must be removed first.
Search continues. I also tried examining the exhaust for the white color mentioned, but with the cold temps it's a crap shoot. I think my breath was whiter than the exhaust, ha. Still thinking I'm going to take it to the indy next week.

Update:
1) Replaced my coolant expansion tank yesterday and haven't seen any loss of coolant yet. I noticed that the cap seals much better on the new tank than the old one (same cap). Probably doesn't mean anything.
2) When my lady was driving behind me today after getting her car serviced, she noticed liquid dripping out of my tailpipe several times. I understand this can be water from normal engine operation or it could be related to a blown head gasket. I'm planning on testing the exhaust to see if coolant is detected in it.

My stick has been broken for 4 years now. But when it did break I was able to see and pulled it out. I don't need a long stick to tell me how full my expansion tank is.
My coolant temp sensor o-ring was leaking coolant for the past 4 months and I just got around to fixing it last week. pretty simple fix, takes about 10 min if ur hands are big like mine. $30 part.

Where's the sensor? I assume it's not the same as the coolant level sensor at the bottom of the expansion tank.

Sensor was only $20 from an online vendor. I did not have to drain the coolant completely. I was replacing the coolant reservoir and the vent pipe, so I had already had emptied the overflow reservoir. The key is to let the car cool. Mine was parked for a few days. When I removed the sensor, only a few drops came out. You need to be quick when swapping the sensor.

Can someone post up what the sensor looks like? Perhaps the one that came out of your car?
