2005 Z4 Advice Needed
New to the forum and new to being a bmw owner... Purchased a 2005 Z4 with 40,000 miles on it a month ago that was in very good shape, pristine engine compartment and you could tell it was taken care of... Anyway, my wife took it to see some family and the service engine light came on which I pulled a code for - P0442 Evap leak. Since I didn't have a good scanner for bmw, I just didn't drive it while waiting for the code reader.
Today I went out to start work on it and when it started up, smoke came out the tail pipe which was a first. I drove it around the block to warm it up and when pulled back in my garage the car was smoking out the hood. On further inspection I see smoke coming out of the rear engine area towards the firewall. Taking an extension mirror and looking all around I see no oil leaking and the engine itself is spotless. There are no signs of an oil leak under the car either so I really don't know what to do... Do I assume it is the valve gaskets and replace it or could it be something more serious in the engine itself? I can't find any indication this model has engine issues, especially with relatively low miles on them but who knows.
Any advice you could provide on determining the cause would be greatly appreciated. Thanks.
