Abstract
An apparatus and method for use on an engine to selectively isolate the oil pump assembly from the engine's lubricating system for indicating which of these is producing an oil pressure problem in the engine.
Claims9
A method for testing oil pressure in an engine to determine if low oil pressure is being caused by a faulty oil pump assembly or by a faulty engine lubricating system, said method comprising the steps of:
- a. removing the spin on oil filter from the oil filter mounting pad of the engine to expose the oil inlet passage, the oil outlet passage and the oil chamber thereof;
- b. closing the oil chamber of said mounting pad with an adapter means to prevent leakage of the oil supplied thereto from the oil pump assembly when the engine is running;
- c. directing the oil supplied to the oil chamber of said mounting pad through said adapter means to the oil outlet passage of said mounting pad for lubrication of the engine;
- d. interrupting the flow of oil through said adapter means temporarily so that the oil in the oil chamber of said mounting pad is contained therein;
- and
- e. sensing the pressure of the oil temporarily contained within the oil chamber of said mounting pad to determine if the oil pump assembly is operating at its rated capacity.

An apparatus for determining if low oil pressure in an engine is due to a faulty oil pump assembly or due to a faulty engine lubricating system comprising in combination:
- a. an engine having an oil filter mounting pad in which an oil chamber is provided for receiving oil from the oil pump of said engine and from which oil is supplied to the lubricated parts of said engine through a hollow externally threaded stud protruding from the mounting pad;
- b. adapter means sealingly demountably attached to the mounting pad of said engine to prevent leakage therefrom of the oil supplied to the oil chamber thereof, said adapter means having a passage means formed therethrough for directing oil from the oil chamber of the mounting pad to the lubricated parts of said engine;
- c. valve means on said adapter means and in communication with the passage means thereof, said valve means actuatable to selectively close the passage means in said adapter means to temporarily prevent the flow of oil therethrough;
- and
- d. pressure indicating means coupled to said adapter means and in communication with the oil chamber of the mounting pad of said engine for sensing the pressure of the oil supplied thereto by the oil pump assembly of said engine.
