[101Volts]

Short reports:

1: I'm not convinced the RLI additive works much. Mistakenly overtreating it may have caused smoke to come out my tailpipe on heat-soaked hot starts. I'll continue using it at the proper treat rate now that I stopped using it as much these last few tanks.

2: The car starter's being replaced soon; the one I've been using turned over slowly and it finally died.

3: I removed the air dam in January; the plastic supports were junk after riding 70-80 MPH on I-80 for 250+ Miles. I plan to reinstall it with improvements.

Tips:

If you're thinking of making an air dam don't waste your time with plastic, just buy small metal corner brackets; they were 58¢ ea. at Home Depot when I bought mine.

If you want to make an Air Dam for an 84 Caprice Classic 4-Door Sedan the bottom of the bumper isn't flat; it goes sharply downward around the grille. I'm not sure if they kept the same bumper shape for all 1977-1990 Caprice cars, Coupes and Wagons included.

EDIT, years later: In case you went to the last post here instead of reading the first one, I have to report that this car was wrecked on September 3, 2017. Sad day, but I'm happy that my Dad survived not only the wreck, but also the "fallout" afterwards. He had an ulcer issue a month later.
