2007 Audi A8 4.2FSI....So, back a few weeks when the temps here in the northeast were in the single digits and wind chills much lower, I suspect that my pcv or crankcase ventilator froze up based on the whistling noises coming from my engine after work when the car was parked outside. Then I popped the hood to check my fluids, haven't popped hood in over few months, noticed a nice amount of oil on the front of my engine and a little on the bottom of the belly pan. This was not like this back in sept when I changed the oil last. The oil was concentrated at the front of engine, nothing at the back and nothing at valve covers.
The car is parked in my garage every night and over the weekends. There is no oil anywhere on the floor. The pcv has since thawed since there is no whistle; it only did it for a few days. My question is, what are the chances the oil leak stopped since pcv thawed? It's been about a month since I first noticed the oil on the engine and the oil level has not dropped according to the dipstick. At the time I had no clue what the whistle was and didn't know a clogged pcv could cause oil leaks.
My next plan was to thoroughly clean engine and belly pan.
