Well, alldata shows the labor rate at 5.9 hrs for the intake gaskets. The usual shop charges 85 an hr. So the labor would be about 501.50, and then if you buy the parts. I would recommend the problem solver gasket for the malibu. It is a metal gasket and replaces the rubber and cork ones that keep going out. Oreilly's sells those for 85.99 plus tax where I'm at, but it is well worth it. I would buy the gasket yourself because most shops will overcharge on the parts and give you the old style one. Don't forget the tax. I would say your looking at between 600 to 700 bucks to do the job. If you have tools including a good socket set with 1/4, 3/8, and 1/2 inch sockets and the ratchets for them, at least a 150 ft/lb torque wrench and a 20-200 in/lb torque wrench for intake bolts you can do it yourself for cheaper. Just print off the intake gasket repair steps off alldata and follow the steps and you should be fine. It is a pretty easy job to do, just takes some time. The problem solver gasket set doesn't come with the egr gasket and you can buy that separate for about 5 to 6 bucks. You can buy the ft/lb torque wrench from any auto parts store. The in/lb torque wrench I would order from harbor freight. They have a good cheap one that runs about 30 bucks.
