Mac2400 leaking air at oil breather hole

I have read both your questions and after taking both into consideration it sounds like it needs new piston rings. On a gas engine it is called blow by but both have a piston with rings on them, as they wear the end gap gets bigger and bigger allowing compressed air to bypass the rings into the crankcase where the oil is, the breather is there to allow air from the room to enter and exit as the piston goes up and down to avoid pressure or vacuum in the crankcase, the air on the top side of the piston is supposed to go into the tank but in your case some of it is going around the piston rings and into the crankcase building pressure and blowing oil out. There is not much inside a compressor like a gas engine, taking the head off and the oil pan should let you take off the connecting rod bolts and push the pistons out the top. This answer is based on the two comments of cant build all the air pressor and it is blowing oil out the crankcase breather. If you hit the 80 psi and unplug the compressor can you hear air coming from the limit switch box that the power cord goes into ? I will wait for your answer to continue.

How do i check the pump

  1. The FIRST STEP in diagnosing any heater problem should be checking the output of the air pump. Determine the air pressure required for the heater model that is being tuned. The air pump, in turn, is responsible for fuel delivery.
  2. If you do not know the required pressure look for a decal on the side (usually) of your heater. This decal will state the model number, serial number, fuel capacity, pump pressure, etc.
  3. If your plastic end cover looks like this......
m29609t.jpgM29609 has 2 threaded holes. The hole on the left has a square plug inserted. Remove the plug. Screw in the nipple end of the gauge into the threaded hole. Check for air leaks with soapy water.
If your plastic end cover looks like this......
m16545t.jpgM16545 has 2 threaded holes. The shorter projection with a hole on the left has a square plug inserted. Remove the plug. Screw in the nipple end of the gauge into the threaded hole. Check for air leaks with soapy water.
4. The other hole (longer projection) has a screw with a hole which adjusts a ball and spring relief valve assembly. Carefully adjust the screw until the gauge is reading the pressure level that is specified on the heater's label. If operating properly, the pump should produce more pressure than is required to operate the heater. The relief valve allows the excess air to escape before being sent to the nozzle.
5. Replace plug. Test for leak.
6. If you are unable to reach the desired pressure spray soapy water around the seal of the end cover- at the same time check the plastic cover for a crack. A cracked end cover will not allow the heater to perform properly and will not allow for an accurate reading. The pump must be set at the specified pressure in order to have adequate fuel delivery an adequate fuel atomization. Replace if needed.
7. If you set the pressure to specs and the heater does not perform properly or the cone does not glow a soft red, then check for other fuel delivery problems such as a clogged fuel filter, cracked rubber hose, clogged or worn nozzle, or a cracked nozzle adapter. Soapy water lightly sprayed in these areas will quickly identify the problem most of the time. Any air leak will create problems.

Echo PB 500H will start and idle but dies under wide open throttle.

turn back on fuel adustment screw for high this will let more gas to carb or rebuild carb

Bank 1 sensor malfuncatoin/lean fuel/slow to react

what engine, no engine size stated so i must generalize. (hard)
you got a CEL then pulled the DTC, bravo that.. well done!@
B1S1 or B1S2, posting the actual DTC wins here,
any other DTC'S or running symptoms?????????????????????
my guess is B1S1 , due to lean lookup. bank 1 sensor 1.
S1 is the keystone of engine fueling (at idle or steady cruise) .
It determines the final air and fuel air mixtures.

the sensor can be bad.?
or any cracks in the exhaust near it.????? (fresh air is 20% oxy)
or engine really is lean.
see , 2 logic reasons, sensor bad or good and is lean for real.

if car has 100k on it, its due, for a change, anywhy
so do that.
then if it comes back, then it real (no cracks)
why is my engine really real.
its lean for a large number of possible reasons...
1: low fuel pressure.
2: MAF stuck high, or if MAP car, map reading to high.
in simple English the air sensors are fibbing showing Low air when it really air.
the air sensors. are the prime sensors.
all fuel is injected based on them. (and temperatures)

3: air leaks, on MAP cars, it dont go lean only races.
3b: air leaks on MAF , causes lean conditions, (most modes)
on a maf based engine any induction leaks too big will cause
the B1S1 sensor to loose control at idle or low speed cruise,Hot)

there are other reasons.. many.
the above is basics.
let it be said, the engine that misfires, sends a slug of oxygen
to the sensors. and causes it to mess up.
this is the bad deal with all narrow band oxy sensors...
they dont see misfire. correctly.

what we do in a shop is see if we can wake up the sensor
(no cracks found in header)
(S1 is the PRE CAT sensor , one more way to say it)
we force the EFI rich, and scan and graph the S1.
how? , well there are 2 ways.
1: is add propane gas to the induction, (air cleaner works)
2: or force fuel pressure higher, on MAF cars, we pinch the vacuum
'hose to the Fuel pressure reg, this makes it go about 10psi higher.
now you know a trick. or two.
the o2 will go rich showing that it is alive. if not , its dead.
or has horrid levels of oxygen flowing by it.
(gross misfire, burned exhaust valves, gross induction air leaks., etc)

Dewalt Aircompressor model 55168 type 2 is leaking on small hole under the adjustment knob how do you fix it from constantly leaking?

Assuming your talking about the regulater it is repairable. first remove from comp. disassemble bottom needle valve and seat by simply unscrewing round cap on bottom of reg. check to see if the valve is hanging up . normally due to air comp. oil blow by. clean lubracate and check for o ring or seat damage. remove 4 screws from top of reg. first loosen adjustment knob to release spring tention once you remove make sure diapham isnt torn or damaged clean lub. reassemble bottom valve push the needle down to make sure it releases and works properly. reassemble top diaphram spring adjustment and cap test if the through cleaning doesn't work and in my experiance it does 85 % of the time you can buy a rebuild kit for it. hope this helps it is a simple repair

My ts4000 trigger is leaking gas from the small hole on the side of it, it will empty the cylinder. if you put your finger in the hole to try to stop the gas coming out it will eventually stop. the ruber...

While it is most likely a bad seal, I would recommend replacing just for the sake of safety. There are just too many horror stories out there about leaking torches, and while propane may not burn as hot as oxy/act, It is still enough to leave you with a lifetime of regret at best. Consider the biggest financial investment in your toolbox ... yourself.

How do I fix a bosch portable air conditioner leak

leaking water? or refrigerant?

if water i would suggest a good sealer/adhesive to seal any cracks in the drip tray, and ensure all pipework insulation is intact and replace as required...the cold pipes can condensate and sweat giving water problems...

if refrigerant, you will need to have:

im presuming all the gas has leaed out hence no reclaim equipment

Blow torch/Oxy Acetalyne rig
Nitrogen Oxygen free
Vaccum Pump
Refrigeration gauges
Refrigerant suited to unit
Leak detection spray
torr gauge

You must be adequately competent to carry out such a repair!!!

1, Pressure test and find leak using leak spray
2.vent system of Nitrogen
3. braze broken pipework
4. repeat 1 and 2
5. if no leaks found vaccum system out with vac pump to suitable torr
6.charge to required weight

like i say only a professional should carry out system repairs.

all the best

Turned on gas at regulator and heard a loud high pitched whoosing noise accompanied by a smell of gas. Taps on unit were in the off position

this could be the rush of gas when you turn the gas on , and the gas coming out of the breather hole on the reg try turning it on slower and test for leaks on the reg with soapy water if it bubbles up you have a leak on the reg, then you would have to change it .
