Compression in cooling

First thing to check is the cap. I blew up a relatively new expansion tank
because the cap wouldn't release the pressure like it was supposed to. If
that's not the case, then I'd suspect head gasket leak. Check for
oil/coolant contaminattion. Best way to check for coolant contaminiation in
oil is in the morning before starting up car. Check oil cap for what looks
like a Wendy's frosty underneath (coolant + oil mix).
Hopefully, it's just the cap.
