Was told I need to have valve cover gaskets replaced for about $600.00. Is this a fair price in 2013 in Nassau County, LI?

It is easily observed with a flashlight that oil is coming out of both valve covers. There is enough oil leaking to drip onto the exhaust and burn as well as leave quarter sized spots where it is parked. The valve cover gaskets will soon be replaced and will most likely solve the problem.

Car started dying out, sputtering. Took it to shop after engine light started blinking. Misfire on 3, 4, 5, 6 cylinders. Found valve cover gasket leaking. Filled spark plug tube with oil. Probable cause. Maybe. All new plugs and ignition coils. Replaced gaskets, seals, and o-rings. $969.00 later, it should be fine. Really like the Avalon. This better be the only thing.

oil leak from valve cover gasket near fire wall took out bolts to valve cover coated threads of bolts with sealer fixed problem
Replace valve cover gasket. Front is easy, rear requires the removal of the intake manifold.

Toyota Avalon 98. This vehicle ran very well but was leaking very little oil in past years. Over time the oil leakage increased and I feared that loosing oil suddenly can cease the engine completely and make this fine vehicle useless. Preventive Maintenance done 1) Replaced both valve cover gaskets (Gasket Cylinder head) 2) Replaced Cam Shaft seals (Valve Sub Assemble Vent) 3) I also replaced the spark plugs ($ 75.00). Seems like the prices of spark plugs have dropped significantly. Cost: $845.00 for parts and labor ( The labor was about $700 and well deserved) This was a important preventive maintenance and the car runs like a watch.
