You need to clean it, then start looking.

Could be the front seal on the crank.

The oil pan can have a hairline crack. It will expand with the heat and leak like a ****. The bottom corners of the timing cover where it meets the oil pan is a good idea to use a little silicon too. You can also check the torque on oil pan bolts but be very careful.

sub'd This ought to be interesting.

I would put it up on jack stands and let it idle after a good cleaning again. Let it run for certain periods of time and then inspect with the car off. Driving it is clearly blowing the oil around everywhere. A one time drive that leaks that kind of oil will be obvious sitting still if you let it run for cycle. If idle brings no leak then rev the engine to get the pressure up and reinspect.

That is a tough one. I would think from front of motor some place. Cant see that much working its way from front to back.
Valve cover, valley cover, front cover.

I agree with timd38, thats coming from the front of the motor, likely a crankshaft oil seal. Mine looked the same way before I replaced the seal

No but its the same as replacing the harmonic balancer. The rack has to come out, drop the swaybar, disconnct the driver side shock and both tie rods and drop the cradle about an inch, remove the balancer then get the oil seal out then replace. Its about a 4-6 hour job

I'm going to try the UV stuff first before tearing it apart. But thank you for the info.

Look the the motor from the top, above the balancer and just behind the balancer, also look inside the balancer at the bolt and see if oil is seeping there.

Is the oil up on the block too or just limited to underneath in the pan area?
UV wont work because of the volume of oil you have leaking, if that much did come out after cleaning and on one drive. Is is above or below the exhaust ports?

Sounds like "the engine builder" should be revisited and questioned. How long or miles has it been since the install?

It appears that the dipstick tube is already out, so checking it should be easy. Of course, if you never removed it when you pulled the exhaust, then the cause of the leak is obvious that the tube was never installed.

I pulled the dip stick out and there is a lil rubber grommet on the dipstick and nothing at the hole in block...

About 10k on motor now.

You do not need to drop the cradle or pull any shock side. Just put the car up on jack stands, drop the sway bar down, unhook the two PS lines, remove both ball joint ends from rack, remove rack mounting bolts, slide rack out passenger side until you have clearance. Then you will have access to the balancer. Remove the puller and install new seal.
