The WMO Hall of Shame is not so much to point out individuals who do stupid things, as it is to point out stupid things that individuals do. There are many different ways to make WMO, all with the same result, but there are just as many way NOT to make WMO.If you are careless enough, your WMO experience may not turn out as you planned and you may find yourself calling AAA or Joe’s Towing.
In the “How To” page, I try to make it pretty clear that filtration is probably the most important thing when it comes to making WMO. Without proper filtration, many things can happen from coked injectors and cylinders to plugged fuel filters and other fuel system damage. The first Hall of Shame item on the list is the old jeans filtration trick. I call it a trick because someone may trick you into believing that all it takes to filter waste oil before you burn it is filtering it through a pair of jeans. This is not a bright idea.
From what I can find, a pair of blue jeans can have a filtration capability anywhere from 5-20 microns. That being said, 5-20 microns is pretty good, right? Well, no, it actually is pretty bad. Consider that a Caterpillar 2 micron fuel filter runs at 98% efficiency. That means that it will catch at least 98% of all particles 2 microns or larger. Can you tell me how efficient your jeans are? If they were even 20% efficient, you would have to filter the oil through the jeans 20+ times to even come close to the efficiency of the Cat filter.
So, instead of ruining a nice pair of jeans, go spend $25 and get a good filter. It will save you money and headache in the long run.
My next Hall of Shame topic is rubber! Get your mind out of the gutter… the rubber I’m referring to is the stuff that is in your fuel system, weather it be return lines, seals, or O-rings. Back in the day, most rubber was made from neoprene, which over time degrades. this process is sped up by contact with harsh chemicals.
Recently, I had issues with air in my fuel system which was causing hard starts and headaches. I began my search for the problem at the fuel filter, then moved to the IP. I found that I had a leak coming from the hard line on the back of the IP to the fuel filter. After further investigation, I found that the olive seals in the lines had not only started to be eaten away, but they were very brittle and cracked. I wish I had pictures.
