On a Baja trip two months ago I noticed a slight rear main seal leak - 2006 Tacoma V-6, 4.0L with about 150,000 miles. It's still very slight, a drip or two per day. So, do I just let it go until it gets worse? I figure the repair will be pretty costly to install a relatively inexpensive seal. What's your experience? Will it turn into a gusher overnight?
