After answering Bill's question, here are a few other 54-specific questions:
1. Do you have a PCV system (probably not)?
2. Do you have a valve cover with vent-slits in the top (54 had slits)?
3. Do you have a vented or non-vented oil-fill cap in the valve cover (no need for vented cap, if you have the 54 valve cover)?
4. How often do you drive your truck?
5. What is the length of your driving when you get the drips? And, what was your average speed?
