After whale-watching in Monterey Bay and a bayside meal at Bubba Gump Shrimp Co. on Monterey's Cannery Row, we headed south on Highway 1. We twice diverted within the few miles between Monterey and Carmel to the 17-Mile Drive, which winds past Pebble Beach.
Compression fittings work by the compression of an âoliveâ between two tapered surfaces and the pipe itself. The two surfaces are the body of the fitting (be it a valve, connector or any other type) and the nut. Using a spanner and a pair of grips the nut is tightened. This exerts pressure on the olive and bites it onto the pipe. Compression fittings work well if the pipe is clean and cut properly.
On a 4 stroke, compression could be lost through the intake or exhaust valves, piston rings, or head gasket. On a 2 stroke, the piston ring(s) or the head gasket. As you can see, a compression test will simply tell you whether you have adequate compression or not, it does not indicate where the problem lies.To pinpoint the problem on a 4 stroke, a leak down test will have to be performed.
