Help, I was thinking about adding some blown insulation to existing loose insulation (6yr old home) and noticed there was a significant area about 4x4 which was open from the attic of the attached garage (no insulation there) and the attic where I was going to add some more insulation. Both sections have there own venting, before I cover this up is it required to be open? Thanks so much for your info. and sorry if the question is confusing.

The area I thought about installing more insulation is the attic of the house (higher than the garage attic) The garage has no insulation in the attic (I plan to leave it that way). Just an opening which is somewhat large where the two connect (both have soffit vents) I just didn't know if the heat from the garage would somehow interfere with the efficiency of the home? Thanks

It's best to leave the crawl hole open. The garage is not considered 'living area', but if you insulate the garage ceiling, you'll have a cooler garage in the summer, and a warmer garage in the winter.
The garage ceiling not insulated does not affect the rest of the house.
Attic ventilation is required.
In the summer, it lets heat buildup out.
It's either 1 sq. ft of vent opening per 150 sq ft of attic, or 1sq ft per 300 sq ft of attic is required.
Your sophite openings need to be clear of insulation also for circulation.

If I understand you correctly, this opening that connects the two attics is above where you intend to insulate?
If so, leave it open. More opportunities for ventilation and exhaust of moisture.
