Where is the oil leak coming from in my Opel Astra?
Hi lads. I have a 2005 Opel Astra four-door saloon. there is a lot of oil leaking from what looks like a plastic valve about two inches in length at the front of the engine. It leaks when driving. Looking into the engine on the left side above the alternator. What is it called and what does it do?
Thanks a mill, Michael
