Relative to the cam tensioners, I don't believe they are very sensitive to oil pressure. Looking at their design, they appear to just be something to minimize chain slap. Regardless, they do their job at relatively high oil viscountcies during the 20 minutes or so that it takes for oil to reach it's operating temps and minimum viscosity.
Anyway, I'm at 80,000 miles on the V10 and 120,000 miles on a 4.6 (similar cam tensioners) in my toad without issues. They've always had at least a 5w-30 oi in them and, in the case of the MH, at least a 5w-40. The V10 also has around 30,000 miles with a 15w-50. Prior to that, I had a 4.6 in a Grand Marquis that was still running fine at 175,000 miles. It also never saw any oil less than a 5w-30 viscosity.
