Hi I知 new to following the forum and have loved my V10 since 2011. The dealer tells me the cam has excessive wear even though I always changed the oil on time and used the correct oil. I need the contact info for a good V10 mechanic who has experience in replacing the cams and possibly rebuilding the entire engine. We love this car
You may or may not have cam wear. I NEVER trust a dealer's diagnosis on something like this. You CAN, and should, have a used oil analysis done by someone like Blackstone labs to confirm/deny the dealer's opinion. The UOA should cost less than $50. Use a MityVac pump to pull the 2 oz sample up the dipstick tube. If the sample shows abnormally high iron you probably have cam wear. Blackstone has a HUGH data base of many engine designs and can advise what is 'normal' and what is not.
The fact that you have faithfully used the correct oil does not necessarily assure you that a previous owner (you have owned the car only since 2011) used the correct oil. Many seem to think that 'oil is oil' and that's that! Just ONCE with the wrong oil is enough to begin the wear cycle.
STAY AWAY from the instant oil change places (Oil Can Henry's etc) you will NEVER get the right oil there.
