Default Oil leak - 352 motor

I've replaced the oil pan gasket and there's still a good sized leak that looks like it's coming from the front right corner (passenger side) of the oil pan. What else in this area could be leaking? Timing chain cover? Any suggestions on how to track the leak down?

I've found the majority of leaks to be either from the valve covers or intake manifold. If it's a large amount of oil I would suspect the intake.

Definitely check the front of the intake manifold. My car is in the garage from getting a rebuilt 390 engine installed. After starting the engine for the first time they discovered an oil leak at the front of the intake manifold. They took it off and used black silicone instead of the front gaskets. That seemed to fix it. I was supposed to pick the car up yesterday, only to find that they had discovered an oil leak in the same area again. This time the are going to use the grey stuff used on diesels.

I have done some online research and I find that oil leaks on FE engines in this area is a common problem. One other area to check is around your distributor opening. There is a seal but they can be installed wrong.

Default oil leak

I had the intake manifold pulled to replace a leak on the back a few weeks ago. I will check it again for a new leak in the front. Thanks to you all for giving me areas to check out.

Default Leak found

The big oil leak was coming from the timing chain cover at the bottom right corner next to the oil pan gasket flange. While i had the cover off, I also replaced the water pump since it was leaking just a little. Slowly but surely, the process of getting the old bird ready for the road is happening. All the oil and transmission leaks are sealed up now. Next big job is to address the overheating problem, and she will be ready to roll. Thanks for your support.
