What causes an oil leak in a VW Passat?
When the VW Passat front crankshaft seal is leaking you will see a trail of oil down the front and side of the oil pan. This is many times misdiagnosed as a leaking VW Passat oil pan gasket (Image 5). The rear VW Passat crankshaft seal will cause a collection of oil to accumulate and drip from the bottom of the bell housing area (Image 6).
Why does my VW Passat have a burning smell?
When the VW Passat camshaft adjuster seals and valve cover gaskets leak, they typically cause a burning oil smell. The passenger side cam chain tensioner seal is located on the backside of the cylinder head and will drip oil onto the down pipe causing this smell.
What kind of oil to use in a VW Passat?
A previous rough service life doesn’t have to mean the end of your car’s engine. Take action and immediately start using the recommended VW oil specification in your car. To prevent this buildup, Blauparts recommends using Ravenol motor oil in your VW Passat.
What to do if you have an oil leak in your engine?
If you do end up changing the plug or oil filter, just make sure to get new oil when you go to the parts store, since you’ll lose engine oil when dealing with either one. If the oil is leaking from the valve cover area, get the torque specs and see if tightening them up will fix the problem.
