Hey gang- I'm looking for opinions on how to approach the issue of leaks with the mechanic that did my rebuild. Here's the story:

Rebuild was performed by a very reputable Porsche specialist (has appeared many times on this forum, generally very positive reviews, tons of experience) just under 3,000 miles and 1 year ago, came with a 1 year warranty, cost was top dollar. The rebuild was comprehensive: Top and bottom end, new Ps&Cs, CIS reseal and refurb, custom cams.

At about 700 miles a large leak developed at the front main seal which the mechanic took in and repaired in connection with the "1,000" mile service. All was well after that except I noticed a few things amiss:
-He used the Tom Amon collar and sealant on the nose/#8 bearing area (maybe this is a good proactive move, but I would expect this to be unnecessary on a fresh engine)
-The O2 sensor connector had broken during the R&R and just tucked up in some wires, unplugged.
-The charcoal canister out line from the airbox was unplugged and the nipple on airbox left open (sucking in all kinds of dirty air behind the filter).
-The roll-over sensor connector on the airflow plate was disconnected or switched with the other identical sensor, causing cold start issues (I switched them, fixed it)
-I failed smog for extremely high CO, took it to another shop with a sniffer and the CO was at like 4.8 - wayyyyyy too rich.
-The car shudders significantly when pulling away in 1st gear

Now, about 2,800 miles after the initial rebuild and 2,000 miles after the first service, I have a number of small leaks and weeping which are noticeable and leaving multiple drops on the garage (valve covers/cam towers on both sides, some random case nuts are wet, looks like new leaking from front main seal, and possibly more form the rear main/nose bearing). The only thing I have done is one more oil and filter change using Brad Penn 20w50 (he used Swepco).

I assume I'm right to expect zero leaks, regardless of the oil change, for at least this amount of time and miles? Should I insist that these all be fixed and the warranty be extended for some reasonable amount of time at least with respect to major leaks?

It's truly gut wrenching to pay someone as much as I did and have issues so soon. I understand these engines leak a bit over time, but basically right away from multiple places? The other issues noted above contribute to my unease.

Any thoughts on how you would approach this with the mechanic are helpful. I'm fairly new to the big-dollar car repair world (typically do work myself). Thank you.
