Sorry forgot to edit this. Did some tests looking for combustion gas in the colling system. Car passed. Checked oil, it's good.

The expansion tank blew the plug out of the bottom and spewed coolant all over. Next day there was some sluggy oil at the back of the car on the ground. So I thought... Crap blew head gasket and that is why I've been running lean and throwing o2 codes and mixture deviation codes.

Well I refilled the cooling system and fix the plug on the expansion tank. Ran the car and it must have just been the crqppy BMW plastic plug that gave up the ghost cause it ran without blowing it off again. The old plug was cracked and finally split it seems.

Might have figured out my lean issues also.... Air filter wasn't on the maf all the way and I think the maf had oil on it from the k&n filter I just put on. As the codes started when I replaced the filter. I cleaned the maf and put the filter on correctly and so far she is running tip top with no codes logged in the DME with my data logger. No rough idle or anything.

Did another cold start today and still no codes. I'm pretty sure the head gasket was just a scare, thankfully.

I'm running 10 psi at max boost rpm.

So for right now the Packard is back in business. The Eastwood clear coat paint came on Friday.

Good to know your still following along z3 buddy. I didn't post on the z3 boards, there was enough info on what might be wrong just from google searches.
