First time poster here. I just got robbed at a mechanic that diagnosed a coolant leak as a bad intake gasket and charged me 600 to replace and flush the coolant and the gasket. They told me I need a new cap, rotor, wireset and plugs and pcv. They quoted me 500 dollars for this because of some expensive type of plugs and cap. I went to rockauto.com and priced it at 150 for parts. Is there any trick to getting to the plugs and cap. It just looks like I need to remove the box located over the cap and rotor and then move a few hoses. Am I getting in over my head, or is it that easy. Thanks for the help.
