Review on 🔧 DAYUAN 17 pc Diesel Engine Compression Tester Kit Tool Set - Ultimate Automotive Compressor Testing Tool by Nick Granner

Purchased to test compression on a Westerbeke 12.5 BTDB (4 cylinder) diesel alternator. a 10mm glow plug adapter is required for this. the kit was ok, very good for the price. The sensor appeared to be within specification. The pressure relief valve worked perfectly. So for $49 I did my own compression test in under an hour. It would cost $300 to pay a technician with a boat ride and back. What's not to like as it's already paid for itself!
