Where To Locate PCV Valve On A Honda Accord 1986 Twin Barrel Caurburetted Engine

Posted in Ignition Systems | Asked on May 18, 2010

How to check vaccum leaks as the car is idling rough and stalling. Carburettor was cleaned and Coil, distributor cap have been changed with used parts. Fuel Pump was changed (but not the filters as I could not get it).
So I have to spray it at the areas after the carb outlet, right? and then how to seal them? use firegum etc? Also pinching the pcv valve will identify something? I cannot ask anyone else to help me so i have to do everything myself. Thanks in advance.

    With the car warmed up and idling, spray some carb cleaner in and around suspect areas of your intake manifold. An increase in engine rpm indicates vacuum sucking in the very combustible cleaner. This hose/gasket/seal needs to be an air tight vacuum.
    The PCV is located in place on the top of your valve cover. It’ll have a <1″ dia rubber hose ran to it.

    The pcv valve is located on the air cleaner housing. There is a hose running from it to the top of the valve cover. It is rectangular shaped. As for the vacuum leaks use a vacuum tester gauge (you can buy one at any part store or some store that sells car parts. it will cost you 20-50 dollars.) I honestly think it is a vacuum leak but if the car has a idle that bounces up and down like the car has a cam in it it could be a plugged EGR valve But it could be some of the following like a the Intake Air sensor the Air control Diaphragm a plugged Catalytic converter But I’m just a motorcycle mechanic so what do i know about cars.

    Try the small things first like cleaning and replacing cheap parts like the PCV valve first. If the problem persists then pay the $30 or so to get it put on the machine to find the real problem. Just because you have them test it and tell you what is wrong doesn’t mean you have to let them fix it. You pay enough for the diagnostics alone. Let them tell you what is wrong and then fix the problem yourself if you can.
