I wasn't using the 40 oil when it burned that much. I currently have that oil and will see if there is a difference if any

Oil pan gasket requires dropping the sub-frame, eh?

It does ... but a $70 engine support bar from Harbor Freight makes that an easy thing to do. Add $55 for a genuine bmw oil pan gasket, a couple bucks for dipstick tube o-ring (where it goes into the block), maybe $50 for new engine mounts while you are in there, and the cost of your oil and oil filter if you are changing that as well (so another $50 or so).

The hardest part really is getting the oil pan in and out because the oil pump gear sticks down quite a bit and reduces the clearance, but it is still very doable. If you have changed a ccv valve, done the ofhg, or changed out the cooling system, then doing an oil pan gasket should be feasible and will help move you up the learning curve quite a bit.

Mechanics don't like when a customer tells them specifically which parts to replace without allowing them to first diagnose the root cause. They know there's a good chance the customer is wrong and will have to deal with that situation. Assuming the CCV system is the reason for the oil consumption problem is a risk and may come back to bite you, especially when you're paying $100+ per hour in labor. I always perform a few tests to isolate the failed part BEFORE replacing, which ensures I'm actually fixing the problem and not guessing.
You're right on this. I assumed the CCV system was the cause. Had my mechanic check it out and turns out there were multiple leaks (non-pressure though). I couldn't tell because the leaks never dripped to the ground. Mechanic said the CCV system was measuring on the lower end and not the cause of the high oil consumption.

The hardest part is the numbing monotony of torquing all those little screws!

That and remembering the "hidden" screws in the bell housing.

It is usually quite messy because it is often very overdue.

Yup, a series of repetitive and tedious tasks that just takes time to work through. The total volume of things to do is intimidating, not so much any individual task by itself.
