One of the cylinders showed only 60 psi on my first check,so i put oil in the cylinder to check for bad rings,it made the compression go up so i cranked the motor to get the oil out and also ran it for several minutes,but when i rechecked the compression it was still up to 160 psi.What does this mean?When i first checked the compression i did it three times and i was sure it was the correct reading. What could causae this.
how to do a proper compression check on 2001 Mitsubishi Eclipse
Asked by for the 2001 Mitsubishi Eclipse
make sure you unplug the injectors, so fuel doent wash down the cylinder walls, it sounds like you have a ring issue, if compression comes up when you add oil, it.
thanks. after i ran the motor and burned out the oil the compression was still higher than before .from 60 psi to 160
