Alrighty, now I'm really confused. I used the block tester kit today. The liquid stayed blue. Followed the directions and ran the test twice with no color change noted. I checked the #2 plug which is closest to the leak and it looked normal. So it appears the leak is only external, yes? Then why do I have the constant condensation out of tailpipes? And why am I having the hard starts with a warm engine?
I didn't have time to check compression but will do in morning.
