Oil leak at the rear end of camshaft
« on: May 07, 2018, 06:37:45 AM »
'87 Montero, G54B engine, has a bad oil leak at the rear of the cylinder head (the firewall end). The FSM shows a circular rubber gasket at the end of the camshaft, and the ASA parts listing also shows a cap in the cylinder head at the cam shaft end. A previous owner tried to seal the cap with silicone sealant but it apparently didn't work.

What is the procedure for replacing the circular rubber gasket and resealing the cap? Is it necessary to remove or loosen the camshaft bearing caps to do this? Is it possible to remove just the metal cap in the cylinder head and just reseal the cap? If so, how is this done?

I don't want to take anything apart unnecessarily. Thanks for the help.

Yeah, it's really that easy. Remove the valve cover, clean and reseal. Silicone only the area around the plug and where the gasket goes over the camshaft then torque to spec.

Fixed, thanks for the advice.  It needed an new circular seal.
