Get PriceJan 17, 2020Doing a cylinder leak down test can tell you more about your engine than you think. Also, a cylinder leak down test can pinpoint issues in specific areas that other tests can not. A Cylinder Leak down or cylinder leakage test is actually similar to a compression test. So, a compression test measures how well your engine’s cylinders are sealing.
Get PriceSEAMTEST leak testing fluid is a low cost fluid for testing tanks, cylinders and bulkheads at 5-10 lbs. of air pressure. It detects smaller leaks than found with other fluids and leaves no greasy or fatty acid residue. To use, thoroughly mix 4 oz. of leak test concentrate with 5 gallons of water. Brush or pour on seams and watch for bubbles.
