It sounds like your fault could be worn rings on the compressor pistons causing slow pressure buildup and excessive oil in tank. Replacing rings, checking poppet valves for proper sealing and having cylinder bores honed should fix problem.

SOURCE: craftsman 1 gallon direct drive oil filled wont build air pressure

It sounds like you may have a broken reed on the diaphragm plate. This is located at the block. Remove the cover, and look for a cast metal assembly with fins. It will be attached to the side.

Stanley Bostitch compressor cpack model runs and runs but won't fill tank.


check for any air leaks and fix as needed. then look for oil coming from cylinder heads , if oil is coming from heads you have blown head gaskets ,it wont build pressure like this. you might also check the pop off valve to be blown open. push the pin in and see if air starts to build up then. If so get a new valve.also check the drain valve under the tank and make sure its closed.

Air compressor slow to build pressure, and noisy.


All large air compressors are very noisy.

How long it takes to come up to pressure depends on the size of the compressor piston(s), how fast they are running and the size of the air tank attached to it. (and if the tank or hoses have leaks)
A 20 gallon tank could easily take 10 minutes to get all the way up to 120 psi. 120 is very high, and probably the limit for the compressor. Depending on what you're using it for, try dropping the setting to say 80-90psi.

Vt558705 campbell hausfeld sounds like running good but not build up air in tank


Sounds like the compressor itself is bad. If it's an oil-less one, the connector sleeve for the motor and compressor may be bad.

86 harley oil leaks out carb when you start it


Your crankcase vents into the carb air filter. This was required by the EPA. All crankcase vented pressure has to be cycled through the engine. So, If you'll look behind your air filter to the rear of the bike, you should see a pipe coming from just behind the oil pump up to the backside of the air filter. The air pressure exhausted from the crankcase has an oil mist in it. There are baffles in the pipe but sometimes during servicing, these baffles get left out. Still, even with the baffles, there is some oil mist that makes it's way to the air filter. This oil builds up over time and causes a drip out of the air filter. Regular cleaning of the air filter assembly reduces this.

If you're getting more than the usual amount of oil, your engine could be "oil sumping". This is where the oil in the oil tank seeps past the check ball valve in the oil pump and builds up in the bottom end of the engine. When you start the engine, the oil pump cannot pump it back to the tank fast enough and it's blown out the crankcase vent tube right into your air filter. You can "reseat" the check ball and may be able to get it to stop doing this.

Or, you could remove the crankcase vent tube going up to the air filter. Put a piece of tubing about six inches long on the nipple coming out of the engine case and plug the hole in the backside of the air filter backing plate. Then, the oil will directed onto the ground instead of into your air filter.

Good Luck

Oil is transfering up to the pipe that goes to the intake of the carb. 1985 Harley 1340cc


The pipe you are talking about is the crankcase vent pipe. EPA regulations required that the air vented from the crankcase be run through the carburetor and burned in the engine. If it's a lot of oil and your bike has been sitting for a while, this is common and is referred to as "oil sumping". The reason for this is that when the bike is left sitting for long periods of time, oil will seep past the check ball in the oil pump and build up in the engine case. This is because the oil tank is located higher on the frame than the engine. When the engine is started, the scavenge gears in the oil pump cannot pump the oil back into the tank fast enough and it is blown out of the crankcase vent. If it's just a small amount of oil that accumulates over time, this is also common. Although the pipe has baffles in it, some oil mist still gets into the air filter. Most riders get tired of replacing or cleaning the air filter and simply disconnect the hose down at the crankcase and replace it with a piece of hose run straight back under the engine with a filter on the end of it. Plug the hole in the backside of the air filter.

Good Luck

Water gets cold to fast have a very old rheem electric water heater and have no idea to change so water stays hotter longer


Hellol Vcja,

I understand that your hot water runs out to fast when you use it. You state that this is a very old unit. The cause of this is calcium build up, their is not enough space in the water tank for water. You are suppose to flush your tank at least once a year to reduce calcium build up. Over many years this gets bigger and bigger and eventually the tank does not heat water at all. I would suggest looking in to purchasing a new tank, as the scale in it is like a big stone and will not break up and flush out of the system.

Thank you for choosing FixYa.com
