You can try switching to a full synthetic compressor oil to alleviate the problem.

Carbon is caused by the over heating of oil. Your problem is most likely an undersized compressor, or worn valves and piston rings.
Regardless of the problem synthetic compressor oil will help.

Hope that helps,

    You should also check the inter stage pressure. A failed valve in ether the hi or low stage will cause the compression ratio on the other cylinder to rise, and overheat the oil. On a two stage compressor discharging at about 150 psi you should have about 50 psi on the first stage.

How do I replace the thermostat on a 1999 Johnson 50 hp outboard.

Thermostat on a 1999 50 HP Johnson is easily replaced. It is located at the top of the cylinder head at the top rear of the motor, just above the spark plugs. The thermostat also functions as a pressure relief valve so when you remove the old thermostat make sure there is no debris, (shell, weeds, etc.), where the thermostat seats. If there is anything preventing the thermostat from sealing the engine will run cold at low speed. This is a problem because it will cause a lot of carbon deposits in the combustion chamber. Eventually the carbon deposits will cause the piston rings to stick in the piston hindering their ability to seal to the cylinder wall. This will damage the cylinder and the piston and the engine will need to be rebuilt. Replacing the thermostat is easy to do. Make sure all components are clean and use new O-rings and/or gaskets.

2545 is a piston compessor if so you've got a busted rod on one of your cylinders , this will fail catastrofic and break out side of compessor but if caught early can still be rebuilt with a few new parts

Pump direction of I R model 2545

Don't bet on it, I once saw a compressor that had 5 belts and hooked to a 400 HP motor and set to run the way the arrow indicated. When they fired it up it sucked the exhaust flat! It should when standing in front of it turn CW as does the motor. I would put a pressure gauge on the output of the compressor and just bump my motor until I got positive pressure on the output of the compressor.

Engine diagnosis and causes for spark plugs carbon deposits

common causes of carbon deposit in spark plug:

1. blown head gasket.
2. faulty piston ring.
3. cracks/leaks in the cylinder head. this is quite serious.

possible solutions for number 3 are:
1. resurfacing of cylinder head
2. reboring of combustion chamber
3. resleeving/replacing of pistons.

Can i substitute common motor oil for the proprietary oil sold for my AM78 Emglo 2-tank air compressor?

Dewalt claims that motor oil will cause carbon deposits to form on piston/cylinder head and on the inside of the discharge tube. I see carbon deposits on most all compressors that come in for repair. The carbon is not reason for repair. Usually forgot to add any oil causing rod failure. I believe that most compressor oils are just mineral oil. If the climate in your area is moderate, and you do not use the unit for 8 hours a day, motor oil will work just fine. The crank is steel and the piston rod is made of aluminum (no bearing shell). What makes the unit last longer is change the oil more often (holds very little oil). Good luck

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.

Check valve

I have replaced countless checkvalves that were stuck open due to debris produced/ejected by the compressor. Most frequent problem was carbon deposits due to wrong type of oil in compessor. The carbon deposits form inside head and discharge hose. All carbon must be cleaned from head and hose when new checkvalve is installed. Use synthetic oil in compressor to prevent carbon deposit. Leaky valves and gaskets in the pump will also casue problems because this greatly increases the air temp discharged from the compressor. I use checkvalves pruchased from and not the sears valve. Good Luck

No pressure

Unloaders fail due to carbon deposits on seat. Unloaders can be found in the head or in the tank. Failed unloaders /check valves cause the motor to strain but rarely prevent pressure from building. Events that prevent pressure from building are as follows: restricted intake; cracked or dirty valves in the head; gaskets torn or burned causing pressure to be redirected into the intake. Root problem is caused by carbon deposits and heat. Carbon can be formed if oil is drawn into cylinder due to worn rings or the wrong kind of oil is being used. Compressor oil is formulated to prevent carbon. Engine oil will cause heavy carbon deposts. Replace gaskets worn or broken valves and bad check valves to restore pressure. enjoy
