header size......question


I'm putting a pass through in the wall between the kitchen and dining room. Here are the specifics:
single story ranch. No basement/slab and above the kitchen/dining room is the attic (no 2nd floor)- The wall is load bearing in the sense that the attic joists rest perpendicular on it but no 2nd floor.
The opening will be about 5' wide by 4' tall. I was planning on using (2) 2x8's with 1/2" plywood sandwiched for a header. I plan on supporting both rooms with temporary wall- I will only be cutting 3 studs.
Questions:
1. Does that size header sound adequate given the span?
2. I know the tempoary wall needs to be "Snug" but I noticed when I placed the temp wall gently with towels on dining room ceiling...there is the chance that it might put a little pressure on sheet rock....I'm guessing that is OK
3. Does the header need to come in direct contact with the top plate? Or can I use cripple studs? One 2x4 on each size attached to the king stud would be supporting the header- thoughts?

For that short a span I would use 2 X 6's not 2 X 8's. If you have them already no harm done just a little over kill.
Cripples will be fine.

So you are on a perimeter foundation then? What's under the wall you are calling load bearing?

under the wall I call load bearing is a concrete slab- The entire front of the house is on a slab (living room, dining room , office, kitchen)- the back half of the house splits (3 stairs up to bedrooms- 4 stairs down to basement)- it's like a split level turned sideways.
So directly under the kitchen/dining room area is slab- directly above kitchen/dining room is a standard attic. In fact- I can stand on that actual wall I am trying to build a pass thru -in the attic- I can see the ceiling joists that span the dining room and kitchen rest on this wall- but the only thing above where I am standing is the roof- Does that make sense? (yes it's a weird house)

Ah. In you opening you said no basement/slab, I took that to mean "no basement nor slab", not "no basement, is on slab". Sorry, my mistake.

You say that the joists are sitting on the wall. Are there any connections from the ridge of the roof straight down to this wall, is there a truss system connecting rafters to joists? ala:

Do any of these resemble you attic space?

yes- there are some 2x4's going from the top of that wall (in the attic)- up to the roof (but not the peak of the roof)- the peak of the roof is farther back toward the rear of the house. Does that make sense? thanks

Are they on every/other ceiling joist? Are they holding up either end of a beam attached to the rafters?

Image *suggests* to me that you are transferring load from the roof to the wall you want to put a hole in. On the plus side the wall you are wanting to mess with isn't your center wall. An interior wall like this isn't taking as much load as the center would be.

That said, I would treat this as if you were putting a hole in a full load bearing wall.
