It could be leaks out of the timing chain tensioner, held in behind the block with 2 10 mm nuts. Take a paper towel and wipe the area below the tensioner to see if there is any oil.
It could be leaks from the front engine seal. To fix take out the belt, crank pulley ect, remove the front cover and reseal with automobile-grade high temp silicone.
You should have someone degrease the engine top and bottom, run engine until hot, then put the car on lift to look from underneath. Then you can find out exactly where the leaks are.
