Bring a large pot of water to boil for the pasta.
In a large saucepan, heat oil and butter and add celery and onions, sauteing until translucent. Add clam juice and mix well to integrate flavors. Stir in clams and continue to simmer until clams open. Discard any clams that do not open. Season with salt, pepper and crab boil seasoning. Remove clams to a utility platter.
Salt the water for the pasta and boil linguini until al dente. Drain well and transfer to pot of clam sauce. Stir to coat and transfer to serving dish, topping with the clams.
