  • Eastwood Engine Compression Tester
Eastwood Engine Compression Tester is rated 1.0 out of 5 by 2.
Rated 1 out of 5 by from Guage does not measure even close to accurate I bought one of these testers, it did not register accurately, not even close it only registers about 60% of what other high quality brands register. I complained, they sent me another tester, same thing it does not measure accurately, this time they would not replace the unit so I have nothing that I can use. I will be getting a different tester from another company.

Rated 1 out of 5 by from I'm not a fan of this compression tester I bought this a while back specifically to do a compression test on a 2.9l Ford V-6. I finally got to it this weekend. The O-ring and thumb screw were too big that the hose could not grab the threads to screw into the head. I then used the rubber push on adapter. As I was holding it on, the tube pushed through the rubber and was hitting on the piston as the engine was being cranked. I thought for $20 it would be nice to have around. Hopefully it works on the next engine I try it on.

According to the instructions in a PDF posted in the description: "After recording the maximum reading, the pressure may be released and Gauge reset by  pressing the Compression Release button on the Gauge (D)"
