Starting noise

4.0L problems that aren't problems.

Mine does that at every start up. 185,000 miles. The actual issue is that the valve cover is extremely thin and does nothing to quiet the valve train noise.

Really nothing to worry about unless it sounds like a cop knocking at your door.

Any way to correct it?

It really is not an issue. It involves the type of lifters it has. It will not cause any issues with reliability. If it bugs you that much you could do the following: Roller rockers and there's a thicker aluminum valve cover out there. Quadratec has them.
