The customer said it was over-filled with oil and leaks when running.  I used my Smoke Wizard smoke machine to diagnose the leak and found it at the front crankshaft seal area. I advised the customer to replace the seal and the timing belt.  After removing the front end and the balancer, I found the oil seal pushed out of the front cover. The excessively high oil pressure forced it out.  I replaced the belt and the seal. What an oily mess!
