I have a 1994 Mazda B2300 and I noticed last week that I have been using about a quart of oil every 250-300 miles so I decided to do a compression test to see if it was my valve seals or rings.
Well here are the results:
Cylinder 1: 150PSI
Cylinder 2: 140PSI
Cylinder 3: 120PSI Dry/ 150PSI Wet
Cylinder 4: 145PSI
Looks like my rings are shot in cylinder 3, that also explains my rough idle.
Also about a month ago my engine knocked on start up but it only happened for about 10 seconds on one day. Then a week ago my engine started knocking again and did so for about 2 minutes but it hasn't come back. I sea foamed the engine Monday also.
