BECAREFUL! Do NOT use a magnet to remove the parts, because that can cause them to twist and alter the timing. Use a pair of pliers or carefully remove the metal peice with your fingers. You might be able to remove the socket, replace the rubber gasket and reinstall it without taking out those peices. I do not know the procedure to adjust the timing, but it should be done by a pro. If you do have problems, the dealer will tow your car to the shop, remove the injection pump and send it off to have it rebuild/retimed, and its not really cheap after u add in towing, labor to remove and reinstall the pump, cost for retiming it, etc.
