oil leak

my sons 1987 turismo 2.2liter non turbo has two oil leaks that i can not find. I installed a new head with cam, new valve cover gasket, new oil pan gasket, new cam gasket. the seals on the passenger side appear ok. The seal on the drivers side is impossible to see. The leaks are persistent and a real nuisance to the driveway. the car runs fine. any suggestion? bruce.

You didnt tell us if you the leaks are from the top or bottom,, you might what to check under the car to see if you have front or rear main leak...not uncommon for the seals for be install wrong....was there any head work done too? you might have a warped head...I had one of those turismo back in school, those heads are bad ones to work with...always warping at a over heat...check to see if the car is leaking while running...(warp heads)...if the car leaks after you turn off the car..(seal leaks)...
good luck Bruce..
