Whats a rocker cover for a Perkins 1006TAG engine?
Where does it fit? I have just bought one, do I need this as a spare part?

Rocker covers, are covers that are bolted on over rocker arms. They are sometimes called valve covers in the United States and Canada, and occasionally rocker boxes in the UK.
In early engines, these covers did not exist. As the rocker arms are critical to having the intake and exhaust valves operate, it was necessary to keep them constantly oiled. With these early engines, the rocker arms would have to be frequently oiled as the oil was constantly being thrown off or contaminated with dirt from the outside environment.
Do you need one as a spare part?


No, the only real reason to replace the rocker cover is if you damange it.
If you had an oil leak you might want to replace the rocker cover gasket.
