The EGR Valve cost about 65.00 from Advance Auto, Mark's installed the part after approximately 5 hours (which could have been crazy for Labor Rate at $83.00 an hour). This seriously labor intensive job was done at a fraction of what he could have charged. Another shop in town quoted me $379.00 parts and labor! Mark's is the #1 shop in Southern Maryland to get your work done, by expreienced professionals at a great price. Military friendly as well!
