I sprung a good size oil leak- where to look?

[billschroeder5842]

I completed the radiator and hose swap successfully (see my anxiety in other threads) with a few minor tweaks this morning. I pressure tested with a tool, found a couple of leaks that I was able to fix and I took her out and all is good.

NOW....

I've developed a good size oil leak. It is located "some where" around the oil cooler hose area near the block. I'm getting pools of oil on the top of the horizontal frame and it seems to spray around, but only on the passenger side. The block itself looks dry.

Now, I put new oil cooler lines on a couple of months ago, but that does not mean anything. Funny as I had no leaks from that area prior to the radiator issue? Could I have damaged something oil related during the repair? I'm pretty careful, but who knows?

I'm going to wait until the engine cools, wash/clean it down and then restart and look for the leak. Hopefully a clean surface will quickly reveal the problem.

Are there any obvious things that I need to check? Are there typical areas that leak near the oil cooler line (beside the cooler line)?

This is weird. Beer-thirty is fast approaching!
