The car is a Toyota Camry V6, 1992. The valve cover was leaking oil, so I changed the gasket. Inside was a lot of thick dark sludgy oil. I cleaned that off the valve cover, and replaced it. But now - the car starts easily, but makes a high pitched sound of metal on metal, and idles at 2000rpm. If I wait ten minutes it will recover and idle normally. If instead of waiting, I drive it, it starts to smoke from the engine compartment.
If I put it into reverse gear while I am waiting, the idle speed drops and the engine sounds better, the grinding noise stops.
Any ideas what to do? What could I have possibly done when I changed the valve cover to cause this? (I didn't drop a bolt in there!!!). Thanks in advance, Kali

You probably knocked a vacum hose off somewhere.
Double check all your hoses. good luck.

The most probable is the valve cover was installed backward.

I've done this on a Chevy v8 long ago.
The valve covers on your car may be similar in design whereas they are tapered one direction to allow rocker clearance during movement.

Double check to make sure it's not installed upside down.

The other possibility, is the valve cover gasket is too thin causing the valve cover to be too close to the cam shaft.
