I could really use everyones help! My vw passat wagon 1.8t gls 4motion is leaking oil and I can't find it anywhere! I recently replaced my crankcase breather hose along with all the rubber fittings that connects it all together along with the pcv valve all from the factory. After replacing the pcv system i replaced my vavle cover and cam gear chain tensioner gasket and half moon seal. I took the time to make sure all the surfaces were clean before putting it all back together. Now my car is leaking oil really bad and I can't find the source for the life of me and when my heat is on defrost I can smell oil burning still. There are no puddles under my car and while it's running if I stick my head near the back of my engine I can smell oil burning but can't find out where. I disconnected everything so i could take a closer look at the cam gear chain tensioner and the half moon seal area and it looks completely dry but I cant inspect that area with the car running. Is it possible that I overtightened the cam caps or cam gear chain tensioner which is causing my engine to burn oil on the inside? I also noticed the cgct has a little gasket where it connects to the wiring harness but I cant imagine losing that much oil from there. Could it be an oil feed or return line that somehow got damaged during the work I did? I just did an oil change and I scored the dipstick so I could keep an eye on the level and within 2 days I am almost a quart low. I spent a good amount of money already and I can't afford to keep guessing so please help me figure this out. I will upload some photos as well.
