I have run into this before with other compressors I have worked with over the years, mine never seemed to do this but now it is;
First let me say that my compressor is an Emglo 1987 vintage, 5HP 220-powered, 80 gallon upright with a 2 stage 4 cylinder pump. I am not sure I think it may be a "GU" model? (I used to know exactly what it was>> but I CRS any more
I bought used about 10-12 years ago and it has been fantastic; never misses a beat, even when I do a decent sized sandblast project (not that often any more) it never lets me down; I have never had to stop work and wait for it to catch up as with my Dad's old compressor...('70s vintage 25 gallon single stage Sears on wheels made by DeVilibiss)
I have definitely gotten my $500 worth of use from it.
All it has needed was oil changes, a couple sets of air filters (having it mounted in my shed away from the garage and the dust has helped keep it from ingesting dust and fumes) and the outlet tube from the 2nd stage to the tank split on me so I went to the local hydraulic hose place and had a stainless braided hose made up for it. not bad for that many years of good service The PO owned a body shop at one time and this was his "backup"/"makeup" unit. He retired and sold the building and didn't need 2 compressors at home.
The issue is that it discharges a white gooey oily sludge with the air, but it is never down on oil level, doesn't knock, and still builds up pressure/ keeps up just fine like it always did. it has just been having this problem for a few months now; probably the last 10-12 times I have used it... I don't use it as often as I used to.
I have 2 water seperators in the shed in series, right where the outlet is and they always fill up with this ****, never used to. I admit i dont always blow down the tank (drain the bottom) as much as I should, probably do that once evret month or 2 (more in the summer when it is hot n humid out but still not dailya s I should) but in the 10-12 years I have owned it, that has always been the case, this white oily gooey **** is much more recent than that.
is this a sign of weak rings?
I guess the good thing may be that being this seems oily, maybe it serves to rust proof the innards of the tank (LOL) ? Maybe not....
back when I bought this, I directly talked to a rep at the Emglo factory in Pennsy. about it on the phone; they even sent me some literature on it at the time
it seems like their customer service really had it together then... there is a local compressor dealer that sells Emglo among other brands, who offered to buy it from me for more than I paid for it, about 2 years after I had it; it was supposedly "that" good and well built of a unit, in his opinion. It still builds pressure, the system gauge is as good a "compression gauge" as you can get (comparing to working on an engine) so I know the issue cant be that severe of an issue to resolve.
If anything. the buildup *may* be a little slower than before it started doing this but for what I use it for (and the frequency/duration that it gets used) it sure doesn't effect me when I use it
The issue I have is this; I know that DeWalt or jenny bought out Emglo (buyouts are often bad things, often making a shell out of a formerly great company) so I am concerned about internal parts availability for this compressor unit... at least the motor, belts and controls/popoff are parts that do not have to come from Emglo. but internal compressor unit parts do, as far as I know. I have rebuilt many engines from lawnmowers to cars over the last 30 years so i have no doubts that I can do a compressor head;
upon rebuilding a compressor;
1) can they be bored out?
2) is it often that they need this or can they usually be honed and standard sized rings etc be put back in?
3) the answer to #1 will answer this are oversized parts available?
4) is the manufacturer themselves the only source for rings bearings pistons and such or do any of the aftermarket autmotive companies (Perfect Circle, Sealed Power etc) make parst for these?
If the cyls are worn to a point of being tapered, out of round etc, while I know that the cylinders come apart seperate from the crank case on this unit, I don't suppose it would be worth replacing the cylinder to restore clearances for what a new compressor could be bought for.
What parts seem to be the more common ones that go bad on a compressor? I do not imagine them running as hot as an engine since they don't ignite fuel within the cylinders
