my engine is running fine, the gearbox feels great...but when park up over night my 320i is leaking oil - it leaves about a 4cm in diameter patch in 12 hours.
are there any common problems that lead to this, i am getting it looked at, but dont want to be stitched up into paying lots....
Depends on what engine you have.
Some (325 - not sure about 320's) have an oil control valve near the filter.
The gasket in this can leak. It is a fairly simple and inexpensive fix.
my coolant light has come on, and after i ragged it once last week, there was a claer/yellowy liquid that appeared to have been squirted out of something at the front of the engine bay....
I had something siilar on 325 sport - turned out to be leaking from the distributor gasket. the oil was mot as much as you have but clean off engine and then go for run amd look to the front of the engine
