Went to pull old 70's wood paneling to paint drywall behind it in spare bedroom, but saw there's no drywall behind it. Decided to paint the paneling. Lightly sanded off the glossy coat with orbital sander and wiped away dust three times with wet sponge, then let dry for a day. Put on three coats of Kilz2 latex primer (four coats on one wall) and still getting yellowish brown streaking on the walls. Is the old stain seeping out of the wood. Is there anyway to hide it with paint? How do I fix this without ripping it down and drywalling.

Yeah, which one. Here's what they say about Kilz2 latex. Note the last word.

KILZ 2 LATEX White Water-Base is an Interior/Exterior, fast drying, water-base, multi-surface primer-sealer-stainblocker with excellent, adhesion, sealing properties and very mild odor. Suitable for application on interior and exterior surfaces, including woodwork, wallpaper, furniture, drywall, plaster, paneling,

Kilz 2 and Kilz Premium are both recommended as "light/med" stain blockers - which apparently means they don't block stains (Kilz 2 doesn't even list tannin as one of the stains it "may" block). Kilz Max is recommended for "heavy" stains, and lists tannin stains as one of the water driven stains it blocks (actually so does Kilz Premium, but again, it only blocks "light/medium" stains - tannin is rarely regarded as a light/medium stain, when working with water-borne primers and topcoats).

In its' defense, Kilz 2, could be regarded as an appropriate adhesion primer for "paneling" - but not necessarily as a stain-blocker for luaun, or plywood backed paneling. For wood backed interior paneling, I believe you will always realize less labor, and better results, if an oil, or shellac, primer is applied first.

Don't put anymore latex on the surface - if it hasn't stopped bleed through in 4 coats, it's not gonna block the stain with 5...or 6 coats. Use an oil based p/s/sk and be done with it - then top-coat with whatever you wish.
