You'll need a pry bar (to take off the old ones) then go to Lowes or Home Depot.... buy new ones (a bratt nail gun would help) and replace the old ones with the new ones. You may want to take a section of the old ones to the store with you to make sure the new ones you have are the same size. Good Luck.

When a customer come in my shop for an oil change your car is checked out completely. The last thing We want is for your car to break after it leaves the shop this is one of the reasons to have your oil changed at a repair shop,we will look it over top to bottom.The EGR valve runs the exhaust gas thru to be burned a second time.This is required to keep your car running at its best.If your state requires inspections to licence your car a bad EGR will cause your car to fail inspection.
