M25XP Air Intake woes

[vanilladuck]

Just making the rounds on my Universal M25 after having the mixing elbow, water trap exhaust and alternator bracket changed out. Like most, the air filter contraption is bumbling around atop the engine with no real ability to filter air and more potential to imbue disaster into the intake manifold

Figured I would update: this is what I'm ordering currently: https://www.amazon.com/gp/product/B00062YQRA

Cheers and happy sailing!

Since so many of us are maintaining good-running Universal diesels, it seems like a good idea to bump this thread for the benefit of newer forum members.
(IMO)

Such and easy and effective peace-of-mind upgrade

I agree this upgrade is essential, based on the mess I found when I opened mine up.

Would be great if we could curate some threads like "M25 Maintenance Essentials"

There's a nice new K&N air filter waiting to be installed on our M25. I notice in the following posts that some folks put on extra contraptions when routing the crankcase vent to the filter.

Universal 5432 K&N air filter modification

I've been searching the website to find the type of K&N filter replacement that will fit the Universal 5432. I know some of you have done this modification but I can't find the blog posting. If someone has the link to their blog that would be appreciated. Thanks!

What are your thoughts on the necessity of including either of those?

On my M18 when I got the boat the valve cover vent hose was run to a disposable plastic water bottle to collect any oil vapor. There was some oily gunk in there. I routed it to the air filter as per Maine Sail. But I just read this Sailnet post which has me reconsidering. The original system might be safer.

M25 what is this and where does the hose go?
