My toyota pickup is leaking oil around the aluminum sleeves that surround the spark plugs. This engine has sort of a double cavity on the spark plug side and these aluminum tubes isolate the spark plug from this cavity. Why is this?

Hi Kevin,

The sleeves and rubber seal needs to be replaced after a certain period of time and when spark plugs are removed.

It is the designed thus so no other way around it.
