That is good news! Nicely done.

How big is this other leak and is he SURE it is coming from that area of the engine? Can you show a picture of what it looks like?
And does he think it is from the oil pan gasket, or the oil pump/front cover gasket, or the front main cranshaft oil seal? Those would be the three main possibilities for where an oil leak in this part of the engine could come from. The second two on that list would require the engine timing system to be taken apart, yes. But none of them are really that terrible of a job. Is the timing belt getting wet with oil? That would narrow it down to the crankshaft oil seal.
The hardest one of the three is the front cover gasket since that one does require the whole front of the engine (timing parts) apart plus the oil pan dropped, tough to do in the car, but can be done if the crossmember is lowered. ngoma had a writeup here of the procedure somewhere from when he and I tackled one together years ago on a 900 series, with some pictures, you might be able to search for it and find it. If you work very carefully you can do it without having to completely retime the engine, by checking IP timing before engine disassembly with a dial indicator and then confirming after reassembly that it has not changed at all. That can save a little bit of time, as long as the person doing it understands exactly what is going on.
But first task is to figure out exactly where the leak is coming from and figure out a plan from there.
And there is still a chance it is residual coming from the valve cover gasket leak! You might need to wash the whole engine to make sure you can find the source.
The idea of looking up michaelovitch is a good one, he seems to not be on here as much as he used to be but he would certainly be a good connection to have if you are anywhere near him.
