rear main seal leak

What could cause a rear main seal to abruptly start dripping?

Engine is a Chevy 350 with HEI, Edelbrock 600 cfm, headers etc.

The engine was completely built new in a shop devoted to competition engines.

The engine has approximately 1500 actual miles.

It has never been overheated or overreved.

Engine oil has been changed at 500 mile intervals.

Engine runs super quiet without vibrations.

Engine never lost a drop of oil till now.

Car is driven in summer and warmed completely evey two weeks in winter

Average temps this time of year average 27 degrees at night and 38 daytime.

Car has been stored in a unheated garage.

Is it possible that with the low temps and the inactivity are the problem.

Sure dislike the thought of having to tear the engine apart to replace the seal

Any help appreciated.

AL

I had the Same Problem

Just a thought. My problem was the plastic oil line that came with the gauge split. Either defective or turned the corner too tight. A replumb with copper solved the problem.

My 96 GMC 305 Vortec does the same thing. When I shut it off in the driveway after driving it, it does not drip instantly but as it cools, it will start dripping. Of course this motor has 262k + miles on it but I have replaced the rear seal and pan gasket at around 230k. I think it has something to do with the cooler weather which makes all metals shrink abit. At this time it is still somewhat of a mystery to me too.
