oiled air filters bad?

I keep hearing all this stuff about oiled air filters... are they really that bad?

I suggest that every one that has one should look very closely for tiny dust trails in their intake hoses and decide for themselves. I personally have seen two trucks with K&N large cone style filters and both had dust trails. I have also seen several factory trucks with dust trails. Spend you money how you want but I have done several DIY intakes for under $40 and have never seen any signs of dust in them. A new engine can cost $6,000-$12,000, it cost me $4,000 in just parts to build mine myself after dusting.

The best way to check is to do a $20 oil analysis. Blackstone is one company. That will tell you if you are sucking dirt and a lot of other information about engine wear or lack thereof and oil performance. By the time you see dirt streaks, it may be too late.

The biggest thing with any air filter, make sure it is installed correctly and is sealed properly. If you use a K&N or similar filter, make sure that if you reoil the filter not to overdo it and DON'T put oil on the inside of the filter.
