Can a leaking intake manifold cause misfire?
A vacuum leak caused by a bad intake manifold gasket can throw off the engine’s air-fuel ratio and cause engine performance issues such as misfires, a decrease in power and acceleration, a reduction in fuel efficiency, and even stalling.
What causes a vacuum leak?
The most common cause of a vacuum leak is a broken tube or hose, but many parts within your engine can wear out and throw off the air/fuel ratio. Several regulators and valves require a vacuum source to operate properly and gaskets/seals help keep the system airtight.
Can you drive with a leaking intake manifold?
Generally a really bad intake manifold gasket will make a car run rough at idle and/or cause a service engine light to illuminate. As far as driving the car, as long as you don’t have a fluid leak or the car is not stalling or running rough, it should be fine to drive for a few months.
What causes oil to leak from the spark plug?
Oil can also leak to the spark plugs through a faulty piston. Pistons operate at high speeds, and they are subject to wear and tear. Likely the piston rings, if there is a crack, damage, or a melted piston, the oil can find its way there onto the spark plug.
Can a spark plug be covered in oil?
This is bad for both the ignition coils and spark plugs as it can cause misfires, and it can also cause these parts to fail. If your whole spark plug is covered in oil, you should definitely replace the valve cover gasket and the O-rings around the spark plugs.
