I am getting ready to work on my car this fall and winter, I have a good oil leak under the car i know the oil return from the turbo is leaking and the the original cap on the valve cover lets oil by, probably just need a new cap.... but was wondering if any one else tackled oil leaks and what i should be looking for or what is common to be replacing, its an 84 300SD with 295K
thanks
