Remove the Intake manifold, Then remove the valve covers and replace the gaskets.

The front is a joke but the rear is a little involved, it requires you to remove the intake manifold to change and while you at clean out the intake manifold with carborator cleaner to gain back some horse power.

A Haynes manual will help alot! I purchased one for about $18. Invaluable knowledge in that book!!

There will be a lot of hoses, clamps, wires, bolts, nuts, air filter, etc. that you will need to remove in order to remove the intake manifold properly. In my 95, I had to also remove part of the fuel rail (?) to access the bolts holding down the manifold in the front. I suggest getting the manual before starting any work on the vehicle. Make sure to set aside a day or two to get it done right. It's not a 30 min. job like with 4 cylinder Honda engines!! LOL! GL!
