Honda Civic Dual Carb 1989 Head Gasket Question
 

Hi, I have a Honda Civic 1989 Dual Carb that is leaking terribly around
the Join between the black head cover and the engine so I am assuming I
need a new head gasket (correct me please if I am wrong). This leaking
oil is then burning up on the hot engine and manifold and smoking and
causing bad smells. How easy is it for a newbie such as myself to
replace the head gasket? Also, the grey plastic cover on the right of
the engine would be the cover for the cambelt? If so, why do I get a
sort of hissing sound from that side of the engine especially when
idling? I probably need to get the cambelt changed also soon as my car
has done 189,000kms.

Any help would be appreciated on this subject

Thanks

Matt
