Wheres my oil going?

[MyLittlePony]

Ok, this is a newly rebuilt engine, new oil pan gasket and everything. Car still leaks oil. Not as much as it did when it was a v6, but theres definitely not a full quart staining my driveway. Anyway, Ive been driving the car for about a month now, and Ive already had to put in an entire quart. I dont know where its going. Theres only a few drops where I park, am I losing it all while driving?

Have you looked to see if you could, at least, get an idea of where the leak is coming from (front, side, rear of motor, etc.)?

Its from the oil pan. It always drops from the same spot, and I always park in the same spot... ...but the amount of oil leaked is no where near the amount I have to put in the car

Well while your engine is running you are building up more crankcase pressure than sitting with the engine off. In other words your engine
is going to leak more oil while driving and moving vs. sitting parked.. Does the leak appear to be coming from only the front or rear of the oil pan?
Oil pan gaskets are common to leak on 5.0s, but not nearly as common as Rear Main seals (also called rear crank seal) which would look
like just the rear of the oil pan leaking.

you say it's a new motor.....it will use some oil till it breaks in and seals up.

trace the trail to see where it's coming from.
