Ok, So I normally do oil filters and fuel filters every year at end of season.

Was looking at my parts list and there are 2 pricey parts that I change that never look used and was wondering if others change them every year or every other.

Breather Element
Air Filter

The breather is $116 time 2 motors.
Air Filter is $60 times 2.

Thanks.
 
If they look clean with a light shined through them wait till next year.
 
My air cleaners and breathers are airseps and I just clean them as needed which is a couple times a year. No need to replace.
 
Just bare in mind Walker recommends replacing the elements after 4 cleanings or ever 3-4 years based on condition. But I have seen them look good after many more cleaning than that. Just look them over very well each time you clean them.
 
I should clarify. All I do is brush off the filter and knock off any debris that may be on the outside. Since replacing the originals two years ago I have only done the "service" cleaning once as I do not put 250 hours a year on the motors. In fact I did not even have 100 hours on them last fall when I serviced them.
 
It is sad that we are approaching that time of year again I don't have many weekends left to use the boat this year due to travel plans to visit my kids at school. It has been a great season!!!!
 
Was on the Walter Site and I see they make airsep for my motor.
Can someone explain the pros and cons of the walker?
I didn't see prices.
 
First, they use a very, very good reusable air filter element made by K&N I believe.

Second, this is what they do:
"The Airsep® Air/Oil Separator eliminates crankcase emissions by actually closing the crankcase on your diesel engine. The Airsep® is the only current system with a patented design that uses induction air to coalesce the hot oil vapor into liquid."
 
If you have lots of smoke in the ER from crank case blowby airseps May be useful otherwise save your money.
 
No smoke. Like I said earlier normally air filters are clean as a whistle and breather too. Seem like waste of money changing.
 
some older diesel engines have had trouble getting the blow by cleaned up, a good example is the Cummins 6BTA.

if you don't have blow by problems I wouldn't spend the money to change the air filter system. there are two places to look for blowby issues, the engine room in general and the aftercooler where the crank case gases are ingested on the intake system. if you find significant oil deposits on the aftercooler fins the walker system is a consideration. an alternative is more frequent ultrasonic cleaning of the aftercooler.
