A few questions on my Hino 220(39)s-gctid388851

[Guest]

1. I have a tube from my valve cover breather that looks home made and extends over my filter. Quite a lot of oil in the mesh filter. Should I replace these with the K&N's and put a breather filter in place of the line? Here is a picture....

However, when I fill it up in the pilot house, it ends up over flowing the reservoir on the motor and then leaks down in to the bilge. Is this because of a bad cap or is this just a crappy design?ToddSlack Tide

I like the K and N air filters on Hinos. You need to add a slobber catcher made with PVC and stainless pot scrubber material to allow valve cover to breath and still keep air filter clean mostly. Output of slobber catcher goes alongside air filter like you have. Those foam filters are crap IMHO. You should find directions and photos of slobber catchers with a search of this forum.

How much antifreeze dumps out, that is why you never get heat exchanger completely full to allow for expansion.

Seems like a Quart or two ends up in the bilg and doesn't matter what RPM I cruise at. Not sure about your comment on the heat exchanger. Engines run 165......

Sounds to mer like you guys are overfilling your heat exchanger with antifreeze. I fill my heat exchanger with antifreeze till it just comes up to covers the brass appearing "strap" that is a couple of inches down in the heat exchanger when you look in it. As mmichellich says below, you need to leave rooms for the heated antifreeze to expand or it blows outt.

And you had better get that slobber catcher installed and the air filters changed before you take the boat out again!!!!!

You guys aren't getting it.....my Stbd motor has a coolant line that runs up to the pilot house. I am not over-filling that as I leave about 1-1.5" and the coolant is not coming out that exchanger's reservoir. It is coming out down on the motor which is gravity fed by the pilothouse exchanger. I am 99% sure that I have a bad spring in my engines cap causing it to leak out at normal pressure until the system gets low enough.

Radiator caps are cheap. How much empty volume do you leave in highest point in the system.
