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.
