I RECENTLY bought a five-speed 1988 Holden Commodore sedan which has done just over 200,000km. After starting the vehicle, you can hear a ticking from the engine. This disappears after driving for a few minutes. I have been told it has something to do with the tappets. What do you think and how can I prevent it?
IF THE noise is a light rattly one heard only when the engine is cold, then it's more than likely to be the hydraulic lifters, or tappets, as you've been told. You don't say if your car is a VL or VN, which was released in August 1988, but I'll assume it's a VL. The reason for the assumption is that the Nissan engine in the VL suffers camshaft wear and lifter rattle. The way to fix it is to replace the camshaft and lifters.
