Thanks, I checked this out and found some interesting info on the change-over. Not sure I want to go through the process yet, seems to be an issue with the oil sending configuration ie complications. Liked the engine cover idea but searching several local salvage yards turned up nothing so far. Let me know if you ever find decent valve cover replacements for the 3.4 might take mine off to powder coat.
