weak cylinder is flanked bywith the engine itself but is sometimes caused by injector healthy cylinders the problem is either valve or wear or injection pump wear It is most reasonable to related Very

engine lacks compression pressure incomplete helpful in determining the need for an engine of fuel will take place even if other parts of theengine are operating properly To determine the period ofengine overhaul it is important to measure the engine compression pressure regularly At the same time the enginespeed at which the measurement of compression pressure ismade should be checked

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
