you are correct about valve guide leakage,but if the oil has a change interval of 3to4 I lean to wards a non synthetic,its far to soon and very costly if not. the other thing that troubles me is the miles,seems far to soon for the guides to be bad,have your Indy do a pressure test ,valve covers off ,see if you get leek when pushing around the top of the valves,if the guides are tight it will not leek.go to a higher oil like 10/40 or 15/40. and be very sure that the light blue is oil and not trans fluid,aleek in the modulator can give the same result.JNT
