On the 1990-1996 Chrysler New Yorker, the 3.3L and 3.8L pushrod V6 engines in the New Yorker develop multiple oil leaks with age, particularly from the valve cover gaskets, rear main seal, oil pan gasket, and timing cover seal. The rubber gaskets and seals harden and shrink from heat cycling over time. While these engines are otherwise quite reliable and long-lasting, the oil leaks can cause exhaust smoke, oil dripping on the driveway, and low oil level if not monitored. The rear main seal is the most expensive repair due to labor access requirements.
Diagnose the leak by thoroughly cleaning the engine, adding UV dye to the oil if needed, and inspecting common leak points on the 3.3L/3.8L V6 including the valve cover gaskets, oil pan gasket, timing cover/front crank seal, and rear main seal. Repair involves replacing the failed gasket or seal, checking the PCV/breather system so crankcase pressure is not forcing oil past seals, and resealing mating surfaces with the correct RTV where specified by Chrysler. Valve cover and oil pan gasket repairs are usually the least expensive, while timing cover and especially rear main seal repairs require much more labor because of front accessory or transmission removal. Typical costs range from about $150-$400 for valve cover or minor upper-engine leaks, $300-$700 for oil pan or timing cover resealing, and roughly $700-$1,400 for a rear main seal depending on labor rates.
Parts and tips from 180+ owners who fixed this issue
On the 1990-1996 Chrysler New Yorker, power window motors and regulators fail frequently, especially on the driver's side which sees the most use. The motor gears strip and the regulator cables can fray, leaving the window stuck down or inoperable.
Replace window motor and regulator as a complete assembly. Driver's side typically fails first. Check the master window switch on the driver's door as switch failures can mimic motor problems.
