Here's the back story:
I put in a used euro e21 316 bottom end with a rebuilt 1.8i head and all stock everything else. Head was torqued to spec and given the first angle torque. I started it up and let it idle for a bit to check everything out, and everything seemed fine, so I figured I'd take it for a quick drive and get it warmed up for the final angle torque.
I got about a block down the road and the coolant temp started climbing fast, so I let off and coasted to the nearest turn. The temps dropped when I let off. I turned around to try and limp home, and the same thing happened. Temp following revs, even with shifts. This time it had almost no power and was blowing smoke out the back. So I coasted again till I got home and shut it off.
After I let it cool down I started it back up with the radiator cap off to see if there were any bubbles when I reved it. Vapor came out, but I didn't see bubbles. When holding revs while parked, the coolant guage will still climb.
Then I checked the bolts to see how tight they were, there were two adjacent bolts that were really loose. Standing at the back of the car looking forward, they would be the two frontmost left bolts. I had cleaned the holes and threads prior to intalling the head, and the bolts threaded down easily til they bottomed out.
So today I pulled the head after months of the car sitting, and noticed a difference between the new and old headgasket. I also noticed the coolant was REALLY BROWN. The new gasket has a copper ring around the area where I think oil travels up from the block, where the old one does not:
Would this cause oil to go into the coolant and/or the cylinder?
The copper isn't chipped, it just had a piece of dirt on it.
I can't see any areas that look damaged or point to a leak, but I did notice this part:
This is on the exhaust side by #1. I had been seeing a little bit of smoke coming from this area. I thought it could be some smeared antiseize buring off but maybe it was steam from escaping coolant?
I put a straight edge on the head, and couldn't fit a .002 feeler completely underneath it at any point, so the head seems to be good.
I'm going to get a magnifying glass and look for cracks in the head, and check the block for straightness, but other than that, the only clue I have is the difference between the two had gaskets at that one area.
