I have a Toyota Corolla 1.6L 1993 automatic. I had a oil leak which I sloved with putting a new tappet cover(the rubber seal) and the seals that's were the holes for the plugs are, and washed the oil that leaked all over the Head and Gear box. Well here's the other problem. When I try to start the car there is only I click noisen but after a long while it will start but if u switch it off sometimes it will start again sometimes it won't. I left it to dry the whole night the day I washed the engine, the next day it started normally but today its acting up again today. I put antifreeze today, can someone give we some advice what could be the problem.
