Oil is not milky colored, dark brown actually.
When the problem happened I immediatelly felt loss of power and engine started to overheat.
Then I pulled over and temp went back to normal.
Just called an experienced mechanic who works aeros and he says I probably fried a wire on a manifold component.
I will post his diagnosis later on.
Thanks to all for your help!!

So the engine lost power suddenly & THEN the engine started to overheat ? Any hissing going on under the hood ? Pinging under load.
Sounding like a leaky valve to me, if you fried a plug wire you would likely have a permanent misfire & the CEL on. Leaky valve could also mess up the O2 sensor feedback, causing incorrect fuel ratio, which in turn can cause plug fouling & misfires. I'd say first problem to sort is the low compression. The engine shaking is probably a misfire, this would also lose you power immedietly. Probably all connected somehow.
