2007 Toyota Mark X Oil Pump — Purpose, Care, and When to Replace

Based on Toyota’s service information for the GR-series engines (4GR-FSE/3GR-FSE) used in the 2007 Mark X, the model is fitted with a crankshaft-driven trochoid-type engine oil pump integrated into the front timing cover. This is confirmed by Toyota Repair Manual sections for “Lubrication – Oil Pump” and the Toyota Electronic Parts Catalog (EPC) listings for GRX120/GRX121 Mark X models, as well as exploded parts diagrams commonly published in technical parts catalogues used by workshops.

The oil pump on a 2007 Toyota Mark X keeps the GR V6 happy by pushing pressurised oil through the bearings, camshafts, VVT-i actuators, timing chain tensioners, and piston-cooling jets. Without strong, clean oil flow, the engine quickly wears, the timing chain can rattle, and the VVT-i can grumble or throw fault codes. It’s a compact trochoid pump driven off the crank, tucked behind the front cover, designed for long service life when the right oil is used and changed on time.

There’s no scheduled replacement interval for the oil pump
