86 6.9 VRV question .murrhee
hi everyone,ok, i got the vacume tool and gauge and disconected the top port and hooked the vacume hand pump to it and disconected the bottom port that goes to the modulator and installed the vacume gauge there and then pumped the top port to 20" throttled it wo 5 times and keep it pumped up to 20" and noticed the bottom port vacume gauge was reading 40 or more and the top port after i pumped up to 20" would leak down without doing any thing? does this mean the diafram is shot in the vrv or does it even have a difram in it ? thanks for any help on this one.murrhee 86 f250 ext. cab 4x4 6.9 ats turbo c6 auto 4.11 gears
