The Exhaust Systems Australia TOYOTA-LANDCRUISER-HZJ70-75-78-79-80R-105R-1HZ-ENGINE-4-2L-6-CYL-DIESEL-2-X-3-PO is a steel header gasket with a 2 x 3-port layout listed to fit the Toyota Landcruiser HZJ70, 75, 78, 79, 80R and 105R with the 1HZ 4.2L six-cylinder diesel.
A header gasket seals the joint between the cylinder head's exhaust ports and the extractor or manifold flange, holding that seal through constant heat cycling. Steel is used here so it lasts under exhaust temperatures. The listing describes a 2 x 3-port arrangement, matching how the 1HZ's six exhaust ports are grouped at the head. It's a service and fitment part — its job is to stop exhaust leaks, not to alter performance.
It's listed to fit the HZJ70, 75, 78, 79, 80R and 105R Landcruiser with the 1HZ 4.2L six-cylinder diesel. That covers a wide spread of 70 and later-series bodies on the one engine, and a gasket only seals with an exact port match, so confirm your specific 1HZ head arrangement with the workshop before ordering.
A header gasket is replaced whenever the extractors or manifold come off the 1HZ — during an extractor fit, a head job, or to cure a blowing leak at the port face. Refitting an old gasket onto a disturbed joint is a common reason a leak returns, so a fresh one is cheap insurance once the manifold is off.
Oak Flats Muffler Men fits header gaskets like this as part of extractor and manifold work across the Illawarra. We clean the mating faces, check the flange for distortion and torque the fasteners evenly so the seal holds across all six ports. At a recommended retail of $34 it's normally fitted alongside a larger job. Send your details and we'll confirm it matches your 1HZ.
