Oil Leak
I own a 94 993. I cannot seem to fix the oil leak on the bottom rocker Cover on both side. It always end with a pool of oil on the floor on both side after the engine comes to a rest. I have put new rubber seals in the rocker cover. Use slightly longer bolts to get slightly more torque to the covers. Round Gaskets on the bolts and still have no luck. How do you all duel with this problem??

You shouldn't have to tighten the covers very tight to seal properly. In fact, you can warp the covers if you get too brutal with them. I'm thinking that you have another leak(s) that is running down the back of the cam carriers and on to the bottom of the valve covers. Perhaps oil return tubes, or maybe rocker shafts. It's going to take some cleaning and investigation to find the sources of the leaks.
