KN filter
Would it be a waste of money to get a KN filter on a truck that has blowby problems. I get oil on the filter pretty frequently. Is it possible to clean the oil from a KN filter. Thanks in advance.

Welcome to FTE 86xlt
I don't think the K&N is a waste of money since it supposedly lasts so long. Much more than paper filters, so they say.
The jury's still out as to whether they're better or not. I do know that most racers use them.
As far as the blowby, either the cotton or the paper is going to get saturated.So, being cleanable, the K&N might be a wise choice.
And yes, the cleaner that comes with the filter will remove the oil.
Again, welcome!

[updated:LAST EDITED ON 04-Dec-02 AT 07:58 PM (EST)]I wouldn't do it. They recommend strongly that NO oil other than their own stuff ever be applied to the filter, so I think that means nasty engine oil would be a No-No. 
It's a $40 gamble if you do, rather than a $6 paper filter. 
Clean out the PCV hose & fitting & replace the PCV valve before you risk it.
Besides: you're not gonna see any of the benefits of the K&N on a worn-out engine, anyway.

I agree. The oil in your filter is most likely due to a bad PCV valve. Change it and you may solve your problem.
Hotrod magazine (I think) did a test on the different air filters, and unless your running 5000+ RPM in a dragster, the K&N filter has no noticable difference from my $6 Fram. I think it was like 1 or 2 horsepower at normal RPMs. Many guys will tell you differently, but the dyno doesn't lie.
It does a good job filtering the air, but nothing for performance.
