I use a leak down tester that applies air pressure from an outside source to the cylinders.
the signs of a valve cover leak are oil on the engine oil is the only thing that can leak from a leaky valve cover
ck for vacuum leak at the pcv valve hose
With a new valve gasket
This depends what shut off valve is in question here. Where the leak is and what type of material is the shut off valve made of.
Schrader Valve is often used to service the A/C system by charging the refrigerant. So, it is possible that the leak could come from the Schrader valve. It could be leaking for other reasons too.
There SHOULD only be oil inside the valve covers. If they leak coolant you have a serious problem.
that is a severe overheat find and fix the leak change the oil and hope you didnt burn off all the gaskets or score the pistons. trade it in soon if you get it to run again.
I am having a stalling problem and I heard it can be the cause of a vacuum leak and if that is true how can i fix it and where is it at?
I would not expect a valve cover leak to cause a car to stall. A valve cover leak can fill the spark plug area with oil which can cause rough running.
it maybe out of timing or the valve seat is leacking use a compression tester to find out if is the valve leak
Dear Honda owner, Valve cover leak? I assume you are refering to an external oil leak from the valve cover, replace the gasket, be sure the new gasket set comes with spark plug seals.
Spark plugs do not leak oil. What you have is a valve cover gasket leak. This allows oil to run down on the plugs. Try slightly tightening the valve cover bolts. It that does no help, replace the gasket.Spark plugs do not leak oil. What you have is a valve cover gasket leak. This allows oil to run down on the plugs.
