Question about 1995 Chevrolet K2500
you could have a valve stem seal bleeding down when the truck sits causing the blue smoke on start up and if bad enough may be fouling that spark plug with oil I have an 89 k5 blazer with 140k on the clock it does the same thing on cold starts and is a common problem on older hige milage gm v8s. also stick with ac delco plugs.
