Start by removing the decorative name plate that sits over the valve covers. It's removed by loosening two nuts: 13mm on 1989-1993 trucks or 19mm on 1994-1998 trucks.

Using a 15mm socket, remove the 6 factory valve cover bolts. The factory valve covers should lift off. If stuck, lightly tap the sides with a rubber mallet until they break free.

On the heads, clean the gasket mating surfaces and bolt holes of any dirt, debris, or old gasket material.

Install the provided gaskets onto the XOTIC PERFORMANCE covers. Optionally, dab assembly lubricant in a few spots between the valve covers and gaskets to help hold them in place during installation.

Fit the provided O-rings onto the new bolts before placing them into their holes. Assembly lubricant can be used on the bolts and O-rings for smooth torquing and a tight seal.

Install the new valve covers, starting with the rearmost cover and working forward. The single valve cover with an oil fill cap should be installed on the frontmost cylinder for ease of access.

Start and idle the engine. Verify there are no visible oil leaks from the gasket surfaces.

Once satisfied, stand back and admire the instant improvement to your engine bay.
