coolant leak

2001 impala 3.8, 165000 miles, external coolant leak on passenger back side of engine. I cant find the leak, and the car has no codes. Is there a test I can do to find the leak, and fix?

when it is dark out use mirror and flash light when engine has cooled,,,you should see leak easier.

you just did the intake manifolds how did the work out other than this leak....

how big of a leak puddle?

The intake manifold swap was a disaster. I am sure I screwed this thing up. I replaced the upper intake, and because I broke a bolt off in the lower intake, I replaced that as well. I have taken this thing apart three times and replaced the gaskets. Each time I put it all back together I get a worse leak than I had before I started this whole process. It will start, but the engine runs so rough I am afraid to even drive it to see if any codes come up. I am at a stand still with this project. I dont want to take it to the stealership, but may have no choice. As far as how much it leaks......It is a constant drip from the frame on the bottom. It gets worse when the engine runs, then slows down when it has been sitting. Is there some pressure test I could do to see where it is leaking?
