How is oil getting into my intake manifold


All vehicles are equipped with a PCV (positive crankcase ventilation) valve that is located on top of a valve cover and connected to the intake manifold with a rubber hose. When the engine is running, there is some pressure from the combustion chambers that gets past the piston rings and into the crankcase. This is known as blowby. The PCV valve allows this pressure to be relieved and vented into the intake manifold. A thin film of oil will form in the intake manifold since the hot gases from the crankcase contain an oil vapor that cools and condenses once it is in the cooler air of the manifold.

Ford escort wagon 1997 code p1443 displayed. what does this indicate & where is the cannister? thank you.


P1443 - EVAP Control System / Vacuum System Purge Control Solenoid Or Purge Control Valve Fault. A fuel tank pressure change greater than minus (-) 7 inches of water in 30 seconds occurred with a purge (fuel vapor) flow at less than 0.02 pounds per minute.

Possible Causes:
  • Blocked fuel vapor hose between the EVAP canister purge valve and the FTP sensor.
  • Blocked fuel vapor hose between the EVAP canister purge valve and the engine intake manifold.
  • Blocked vacuum hose between the EVAP canister purge valve solenoid and the engine intake manifold.
  • EVAP canister purge valve stuck closed (mechanically).

  • Possible Solution:
    Check for blockages between the fuel tank, the EVAP canister purge valve, and the engine intake manifold. Check for obstructions in the EVAP canister purge valve diaphragm and ports.

    The canister is on the passengers side near the firewall if I recall correctly.

    Hello, i have a coolant leak i thought it was the water pump but the leak is above the mount bolt of the water pump beside the valve cover no coolant has gone in the valve interior, could it be a cracked...


    A crack in that area of the block, while possible, is highly unlikely. A crack in the block usually happens in between the cylinder walls on the side of the block. It is most likely leaking from the intake manifold gasket that connects the intake manifold to the heads, or if the upper radiator hose connects to the intake manifold, it could be leaking from the thermostat housing or hose. There are also coolant temperature sensors that are mounted in that area. Or last but not least, it could be leaking from one of the freeze plugs in the end of the head. Coolant runs through the block, heads and intake manifold.

    Vacuum leak


    mine is doing the same, it's your pcv receptor on the manifold. that hard plastic cover is actually part of the intake itself, if it "came off" it would cut your intake in half. that seem seals the two halfs together. you gotta pull the whole intake off and replace it... or jimmy rig it.

    I have a 3500 chevrolet pickup 454 engine, i need a diagram of the intake manifold something may be blocking the ports for the performance of the egr valve.


    The egr valve is pluged up from carbon build up and it quit functioning. take it off clean it up, and also inside of intake with a screwdriver and shop vac. and then purchase a new gasget thats like a screen, they sell them at autozone and put it back on. the screen gasget is for any chunk that you missed in intake and trys to plug up the egr valve again.

    Leaking oil bad


    If you're certain it isn't your oil filter, then it can only be three other things. The first (and easiest) thing to check is a small diamond-shaped plate on the side of the block, under the intake manifold, towards the alternator. It has a bolt and a stud in it. Verify that both of those are tight. If they are tight, check the four bolts that secure the "push rod cover" to the side of the engine. The push rod cover runs the length of the engine and is located directly under the intake manifold. This was the culprit of my oil leak, and I imagine it will be yours also. However, if you find that those bolts are tight and no oil can be found leaking from that area, check your valve cover. The Fiero valve covers were stamped from very pliable steel and it is difficult, at best, to get them to seal correctly. Problems usually occur when people torque the bolts too tight and bend the valve cover. I recommend a product called "Indianhead" gasket shellac. Remove the valve cover and ensure all gasket surfaces are clean. Ensure the valve cover's gasket mating surface is straight - straighten with a hammer and block of wood if needed. Follow the directions on the bottle to the letter, making sure to coat your valve cover gasket surface, both sides of your gasket, and the gasket surface on the head.
