I detail vehicles for a Ford dealership. I am very good friends with the shop foreman. My 2004 Ford Lariat, 5.4 3 valve engine, has 51K miles on it. I had my shop foreman friend replace the transmission cable. He was listening to my engine and said the VCT solenoids need to be replaced. I was going to do a UOA on my engine after he advised me to. Will the VCT'S affect the outcome of the UOA?
