So I have this 2004 325i, it has very obvious over heating issues, bad expansion tank and thermostat confirmed with an external leak. Now where I get stuck is at this part, the other day I was driving and randomly started dumping white smoke from the tailpipe, it’s done this before then went away this one also came and went on cold start it don’t show up right away until about 20 seconds after, the oil is fine and there is no misfires so if anyone can help thanks here’s what the smoke looks like.
