If the heads were taken apart most likely the valve plate was place backwards causing air to come out of the intake. If the valve plate is on correctly, air coming out of intake is caused by faulty gaskets or leaking reed valves. Good luck

How old is the compressor ? This trouble shooting is directed to the vane and screw types of air compressors.

Caution,
For exact information on the equipment you are working on, go to the manufacturer’s maintenance and repair manual.

Here are some possibilities.

Compressor does not reach design pressure or capacity:
Air Pressure safety valve is leaking
Receiver air valve is open
Unloader valve is leaking
Loose Piping or fittings

Compressor will not load or unload:
Unloader valve defective
Air control valve is sticking or dirty
Unloader pressure is improperly set too high or too low
Water in the control lines
Plugged control lines

The air compressor CFPM is low:
Dirty air compressor air filter
Defective air intake control valve
High idle on power source improperly set
Damaged or worn rotor blades

SOURCE: Compressor is building up pressure very slow.

It could very well be the valve plate however before you order parts take a look at the cylinders. Unplug the unit, remove the cover from crank side and turn the compressor by hand till the/a piston is at top of stroke. Examine upper cylinder for scratches /wear or failed vinyl piston ring. On oil-free compressors, dirt and grit is sucked-in from the bottom of the cylinder and causes leaks between cylinder wall and piston. If scratched, air pressure is leaking down thru cylinder wall. Failed reed valves cause a pulsation at the intake port (air seems to be pumped out the intake). If you see a model number anywhere on the pump that begins with " WL", your pump is made by Campbell Hausfeld. Parts can be ordered from www.chpower.com. other-wise order parts from sears parts. Cylinder kits are around $40. Good Luck on the repair and email if you have questions.

the back pressure valve has failed it costs about 15.00 and can buy from any truck parts store That's Peterbilt trucks or any large truck stores it's one of two sizes 1/2 inch or 3/4 inch when you pull it off be sure you know which way the air flow is or it will not build up.

SOURCE: Air leak on top of cylinder head

Hello,
In all likely hood a flapping noise coming from the cylinder head means an issue with either the intake/exhaust valves or one of the restrictor plates. If you click the link below you can find a diagram for the cylinder head, page B part #107 and #110. You can also get replacement parts from them if needed.
I really hope this helps.

Why wont my steelcraft 13 gallon 5hp model ta25 build up no more then 20 pound of pressure and all i did was change the oil?


Check all connections for air leak including the water drain valve with soapy water. If no air leaking from connections, spray soapy water on head area where head attaches to the cylinder checking for gasket leaks. If no leaks are found, most likely problem is in the head /valves /internal gasket leak. If head gasket or valves are leaking, you will notice that air seems to blow out of the intake filter (normally there is good suction at the intake). Good luck

How to remove muffler intake from Porter Cable CPF6020-1 air compressor


To remove the air filter intake muffle you will need to remove the 4 screws that hold the head on to the pump.
There is a O-ring under the head you will want to put a little vasoline on before you reassemble the head back to the pump.

The new muffler kit should be the KK-4981

Alton 1/3 hp 2 gallon air compressor, building no pressure and sounds funny


Is your compressor a piston compressor? It may be that the valves in the head are shot?
Remove the Air Filter and quickly place your hand over the air intake hole, if you feel it **** AND blow, then theres your problem (It should only ****) these can be replaced.

Hitachi Ec 119 compressor will not build pressure beyond 25 pounds; no air is heard leaking after I power down the machine. Is it likely the check valve or pressure switch?


If your compressor keeps running and only builds to 25psi, I would suspect the reed valves, head gaskets or a leak. With the compressor running spray soapy water on all fittings, around the head area and tank components. If no leak is found, remove the air filter and feel for suction at the intake(make sure head is not too hot). If you feel good suction at first then suction is lost after reaching 25 psi, most likely reeds or gaskets (with bad reed valves, sometimes you will actually feel air blowing out of the intake). Good luck

Hi Jim,

Disconnect your main air supply from the comp head to the receiver/tank and see if their is a reasonable air supply to atmosphere.

If not check that air is being taken in by the head intake filter

My ssl5l compressor builds pressure real slow now. Rings or Valves? it did get a little warm while sandblasting lately....


Very rare to have problems with rings. Blow-by would produce high pulsating pressure in the crankcase causing oil to blow out the oil filler plug/ dipstick. If normal crank pressure, suspect problem with valves or gaskets. Remove air filter cover and check for air blowing out of intake or very hot head or air discharge tube. Leaking valves or blown gasket will cause low volume/ low pressure and hot discharge air. Remove the in-tank checkvalve and look for carbon deposits /debris build-up. If the checkvalve and the interior or discharge hose are coated with oil deposits /carbon, most likely problem is valve plate/ gaskets /head. Good luck with your repair.

Air blowing out the intake


Cylinder head has two ports, intake (clean air coming in) and exhaust (air going into tank). Problem with my Sears compressor was the gasket that separates the two ports was blown. This causes exhaust to come out the intake port. Blown gasket may be a result of adding to much oil. Disconnect power supply, remove cylinder head, order or make new gasket, and reinstall. Connect power supply and watch the pressure build. My first attempt with home made gasket material allowed the pressure in the tank to build. Air was coming out the side of the cylinder head. Going to NAPA to buy the correct gasket material since Sears don't seem to sell the cylinder gasket anymore through Sears Parts. Good Luck

95 xr7 wont start after head gasket up replacement,got spark got fuel set timing. only thing is intake blows instead of sucks? is that normal? what could the problem be?


Do you mean the air intake? If your air intake blows and the motor doesn't run it may mean your valve timing is wrong. How did you set your valve timing after you took off the head? If you weren't careful you may have set the timing for number 1 cylinder on its exhaust stroke and not its power stroke. This will put your timing 360 degrees out.

Incorrect valve timing may produce the effect that the engine pumps air out of its intake when it is cranked.
