Valve Cover Gasket Replacement #lexus #toyota #ls430 #sc430 #v8 #3uz

how to replace valve cover gaskets and related components on a 3uz-fe engine. this is on a ls430 but the process is the same for sc430 and very similar process to the tundra Sequoiah lexus and toyota v8 engines with timing belts. during this job i recommend replacing valve cover gaskets, spark plug tube seals, engine breather hoses, valve cover bolts/washers, pcv valve, pcv grommet, pcv hose, and spark plugs. The evap hoses may also brittle, so they may need replacement as well. i also recommend using toyota/lexus original fipg seal packing for engine sealing ( the black one)
