Lifter Noise ?
 

I have a 2004 Santa Fe W/ 3.5L V6, It has 15500 miles on it. Up to now there
has been no problems with it. I am using Mobil 1 5W30 with Hyundai oil
filters. The other day When I started it there was a lot of noise coming
from I believe the valve train also it was running real rich, I could smell
the unburned gas. This went on for about 30 seconds then cleared up and has
not happened again. When I test drove a Santa Fe before buying mine that car
had the same noise coming from the engine only it did not go away. The
salesman said some of the vehicles have that problem and something there
shop does to correct it. Has anyone run into this problem. Lifters leaking
down ?
