Engine oil filter 1MZ-FE Toyota Camry 2001 - 2006. General information

On vehicles with 1MZ-FE engines, a full-flow type oil filter with a replaceable paper filter element is used.

The filter is installed on the outside of the engine, which allows relatively quick replacement of the filter element.

A bypass valve is installed in front of the filter element, which opens with an increase in pressure in front of the filter, which occurs if the filter element is clogged with contaminants. The bypass valve opens when the oil pressure exceeds the force of the valve spring. In this case, the oil passes through the bypass channel, bypassing the oil filter, and goes directly to the main engine oil line.
