Audi A4 Quattro Engine Oil Leaks

(2 reports)

Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.

Valve cover & oil filler cap gaskets are rubber, and deteriorate badly after about 120k miles. Replace when leaking, or oil will drip onto exhaust manifolds and smoke. Also replace the inlet elbow to throttle body gasket (also rubber) as it hardens and wears, causing inlet vacuum leak. This may cause a false MAF sensor code. -
