Buick Skylark Problems
RepairPal has identified the most common problems with the Buick Skylark based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
An engine oil leak may develop from the rear of the engine. This is commonly caused by a failed oil pump drive o-ring seal. The leaking o-ring should be replaced to correct this concern.
The front or rear exhaust manifold may crack causing an exhaust leak. Our technicians tell us the manifold should be replaced to correct this condition.
The timing chain tensioner and guides are prone to wear and may develop an abnormal noise, requiring replacement.
The engine vacuum hose to the MAP sensor may crack resulting in a vacuum leak causing the engine to run rough and/or stall.
The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.
A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.
