  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

FE/FC 2017 fx350 Water in oil

I got water in the crank case oil. I'm trying to figure out how it got in there. My theory is though the crank case vent. I was hoping some others might have input on this.
 
When a hot engine hits a cold waterhole the engine cools so fast that it will suck water up the transmission vent hose out of the water hole like a drinking straw. Either run the vent higher up under the tank or in the air box or poke a small hole in the vent hose near the engine case and it won't be able to siphon water. My Italian WR250 did it twice before I figured it out.

That's a lot more than I think could be siphoned. Mine was maybe an ounce of water which did turn it to a milkshake since it doesn't take much water when it's whipped up by the gearbox. If you inner water pump seal was leaking and you topped off the coolant a few times before you realized the oil was milky that would make more sense.
 
Your 350 I think should hold about a quart and half for oil change with filter. So being half quart give or take over max level is quite a bit. It doesn't take much water in oil to make a milk shake but the quantity on contaminated oil is a real concern. Unless it was over filled with oil after oil change. I'm guessing over fill and either water pump seal leaking or head gasket. Water pump seal is easier than head gasket so I'd start there. Only other thing and this is a long shot had a buddies bike do this. After he washed it he got too much water in exhaust pipe and it found its way to oil.
