Thank you, Dan. Perhaps I should see how others have upgraded their intake "filters" (such as they are) to a more modern and protective one. I have a very early boat (1986, hull #38) which may need upgrading. Maybe Stu and others of this vintage can advise how best to do this.
Brent,
Like everything in boating, there is no "Best." Everything is an OPTION. Those options have been discussed in this post and many in the C34 Tech wiki.
I have chosen to use a modified version of Ron Hill's "beer can" but I used a "peanut butter" jar with a hole in the top for the hose and multiple other holes for venting. I did this primarily because I could never get the elbow connection to the engine to move and I didn't want to break anything.
Others, like Steve W described, have routed their crankcase vents to the air intake, with many different ideas as to whether or not to just hang it on the intake or to drill & tap and to make a positive connection. Whether you use a K&N filter or use the newer version of the air take "filter" with the foam cover, is your choice.
If you look at the engine manuals or the Torreson website (
www.marinedieseldirect.com), you might see the "old" and "new" (1986???) air filters.
This is NOT rocket science, and only has a few options.
Your boat, your choice.

Sorry if I'm a bit cranky today, I'm still wrestling with my darned galley sink drains. Hadda buy a Dremel tool to get the danged plastic nuts off. Yeah, I used to have an early Dremel tool, but its motor bit the dust like many of the earlier models. Lets hope this puppy lasts longer.
