Mostly visible on cold start ups. I just switched to conventional coolant from evans just a few days ago. Has been almost 2.5 years since milled head/new felpro head gasket. Should I try a head bolt retorque first???
Burning coolant did not seem to be an issue before the switch to conventional coolant.
thanks for the help!

It seems like one or more cylinders is missing on cold start up....I guess some coolant is seeping into the cylinder/s.....it smoothes out in roughly a minute.....but I definitely know coolant is being burned....
I will check the plugs in hope of finding where the problem is........what aggravates me is that I just installed a Cloyes double roller timing set and the car runs much stronger now.

You ought to see some evidence in a color change on those cylinder's plugs and some crusty particles or deposits; might not be much but it'll be there. A retorque is worth a shot, but not likley to fix it IMO so long after the gasket was installed, unless a head bolt really backed out a lot. (Again not likely.)

Thanks, I know it is wishful thinking but I will inspect the bolts/tightness on tear down....I guess I know what I will be doing on one of my upcoming weekends!

Ok, no leak down or compression test performed but I think I can be pretty confident that I found the problem. One or more of the I/E studs near #6 are leaking and streaking downward on the block. That's my focus now.
