Can't break what's already broken, huh?
Thanks, Gene! And yes, if this had happened down South somewhere, I would have been in a real tight spot. I still have some hopes that this is just a thermostat. I'll have the oil tested and see what happens.

Yep, coolant level is fine. Fan was coming on fine.
The reason I want to get the oil tested first is because when I let it cool down and re-start it, the overheat message comes on within a matter of 2-3 minutes. That combined with oil found in the coolant tank - I want to know for sure whether the gasket is leaking from the lifters issue.

The lifter issue is limited to the N52 engine, btw, so don't worry
Reposting the service bulletin on the ticking noise from another thread:
(I believe, this is the correct SIB #, but am not 100%; definitely the correct SIB though) SI B 11 09 07
September 2009
This Service Information bulletin supersedes SI B11 09 07 dated January 2009.
SUBJECT
Intermittent Hydraulic Valve Adjuster (HVA) Noise
MODEL
All E82, E83, E88, E85, E86, E60, E61, E70, E90, E91, E92 and E93 vehicles with N51, N52 or N52K engines produced approximately up to November 31st 2008; refer to cylinder head casting identification attachment.
SITUATION
An occasional ticking or rattling noise from the camshaft hydraulic valve lifters (HVA) may occur during cold engine starts, due to frequent short-distance driving, or the noise may occur for an extended period of time even though the engine is at operating temperature.
Improved parts were phased into production beginning on 10/1/2008 and fully implemented on November 31st 2008.
CORRECTION
Do not perform the bleeding procedure that was previously provided in SI B11 09 07 which has now been deleted.
All vehicles produced between 10/1/2008 and 11/31/2008 must have each vehicle's cylinder head casting number identified before hydraulic valve lifters (HVA) replacement, due to staggered implementation. Refer to the attachment for the casting number location. Vehicles produced after 11/31/2008 have already been fitted with improved parts. Vehicles produced prior to 10/1/2008 will require the new parts.
Improved Casting Numbers
N51 (B30)
7588277.01
N52 (B30)
7588273.01
N52K (B30)
7588271.01
A cylinder head casting number that does not match will require replacement of the 12 exhaust camshaft hydraulic valve lifters (HVA) as per Repair Instruction RA 11 33 050, Removing and installing/replacing all rocker arms. Only the exhaust camshaft and rocker arms have to be removed in order to replace the hydraulic valve lifters. Do not remove or replace any intake camshaft valve train components.

V, awful to see and here. My N52 engine has the same ticking noise when cold do you think I should get it checked out? I mean I have made BMW aware of it but they give me the run around sayings its fine. My warranty expires in 2 months so I need it done ASAP.
Keep us updated.

Thank you!
Thanks, brother!
Dude, quit acting like you care, man - you've got warranty! 
Seriously, if you're covered, just forget it - worst thing that can happen is you'll have to drive a loaner for a few days 
Thank you! Theoretically, there's still a chance it was just a thermostat, but I want to get the oil analyzed and make sure that it is clean.
It will be fine. Worst case - I'll have to buy an N54 engine off eBay and have Motorcepts shoehorn it into my ride
