    • Volvo D4 which test do you trust

      This topic has 17 replies, has 2 voices, and was last updated byTony Athens 4 years ago

      October 17, 2019 at 8:12 pm Fighting lack of power loss of rpms . Computer scan shows weak compression/ power output on cyl #1 & 4, and full output on 2&3. Mechanical compression test shows cyl 1&2 equal and cyl 3&4 equal . However 1&2 are 50 lbs less than 3&4. Which test do you trust ? If computer scan is reading wrong would that mean the computer/ecm is bad ? Thanks

      November 16, 2019 at 11:17 am So far so good, but that looks like an intake valve? —————–Is that #4, the most likely one to have seen water unless this was a v-drive application , then #1..Exhaust valves are the ones that will show what is going on as to water.
