Hey Guys, I own a LandCruiser and it currently has a leaking rocker cover gasket and the guys at my local Repco are not sure between the sizes which they have. They have a 3mm and a 6mm Gasket but i'm not sure which one will fit. Car is a: 2000 Toyota LandCruiser 100 series 4.2l Petrol, Straight 6, 1FZ-FE engine Any help would be greatly appreciated, Thanks in advance, Liam_Poor
