This compression testing tool will provide users with a compression reading for the cylinder and sleeve to determine engine wear or damage. An initail test by turning the engine over as if you were starting it will show the psi as a starting point. As the engine wears out or is damaged, the psi will show a lesser psi value. It makes a great tool for determining if you ingested dirt into your engine or if it ruined the piston and sleeve due to high temperature. It can also help with shimming the engine head for performance. Retail price for this item will go for $30 to $40. Posted with eBay Mobile
