What do you guys think. I have checked everywhere for leaks and cannot find any. So i did a pressure test and lost 4 psi over 2 days. Car runs fine and i have checked plugs for wetness and there is none. If i had a bad water seal do you think i would have lost a lot more pressure over the two day period? Also when i pressured system it was about 100 degrees outside and when i got home a couple days later it was around 70 degrees when i checked gauge. Thought maybe the change in temp would effect pressure.

 

you are fine.
