Going to make it short.
Have made a couple other posts but this is a new issue.

Just went and grabbed the boat for tomorrow and found oil leaking all the way down the back of my motor. Appears to be coming putting the mouths of my carbs.

Smoked like crazy last weekend in the trash can while working out some other issues, and i find this after its been sitting. What causes This? Is this a sign of a blown oil side pump? Is it safe to run?

Is this finally the day I can the VRO and premix?

Trying to be on the water at sunrise (4/22), please help people convince me it's otherwise not safe. thanks!

1987 Evinrude E40ELCUD w/VRO

Ok, well. Wont let me upload pictures. Says 200mb is too big. Then anything over 40,000 whatever is too big. Will be a thumbnail before its able to post. sorry.

Just envision oil coming out the throat of carbs amd running down under the.motor and dripping out the back down to the prop....

It got hot where I am. If your oil tank isn't vented the pressure will force the oil out whichever way it can. If I were you I'd premix gas just in case and run her and see if the oil alarm goes off and if it is actually pumping oil.

Very good point, sir .well received. Has been in the 80s here lately, too.

Im not up for cutting my oil line just to see off its pumping. I know the alarm works and i have wicked smoke. Confident it's getting oil.

Heading out in.the morning. Will check this again before i leave just in case anyone else has any pertinent information for me. Thanks

thinking Sut is implying to mark the oil level on the tank and check the level after use to determine oil usage...not cutting the oil line to check

Yup. If you suspect issues with your Vro adding oil to fuel for a brief period is pretty standard.

I only have 1 fuel tank. Mixing 50:1 or even less would make sense, but I.wouldn't want to run the VRO and premix at the same time for obvious reasons.

Then if it turns out i am pumping oil, all that premix must be dumped.

Ill update a bit since i did hit the water since i posted this.
I think you were right with the idea of heat induced pressure buildup. Some of my lines could be secured better, probably just pushed it all out.
Seemed to burn up the excess oil fairly quickly at launch and was back to normal.

She ran great that day all the way up to the last 5 minutes of my trip. I made a separate post for that though.

And Faztbullet, are you referring to inside the cap on the oil reservoir? It appears to be a flat circular screw on style cap. But if its inside the cap itself, it may indeed be equipped with said valve that iv previously been unaware of.

Thanks for all the help folks.

Is your fuel tank vented correctly or are the vents closed and the fuel line still connected. What usually happens is the fuel tank can pressurize enough to push fuel out the carbs and when it comes out the gas evaporates and all that is left is the oil. This may indicate a bad needle valve. Another possibility is you tipped the motor up and the fuel came of the carbs and the airbox gasket is bad letting it all drain down the motor. It may just be a bad airbox gasket leaking. I use the VRO have installed it and like it, I personally have never seen enough pressure in the oil tank to drive it through the carb. To pre-mix the tank I like to use the Amsoil 100-1 pre-mix that way if the VRO is still working Less risk of fouling out the plugs. Evinrude actually recommends that pre-mix in the owners manual for a break in procedure so no problems there. Don't dump the pre-mix just keep running it

Im unsure. Im using the OEM OMC 6 gallon metal tank with the 3 position filler cap. Has the worthless little fuel gauge, and the standard pin/clamp style hose connection.

Have been told the vent is in the cap and you have to have it in the 2nd position so it can breathe. Others have said the vent is built into the hose coupling, so im unsure.

And no, definitely didnt tilt the motor. Had it running good in the garbage can the previous week. Came back and found the oil running down the back length of the motor. Appeared to be coming out of the throat of the carbs and leaking downwards.

I also have some small lines with that aren't fully secured. I cant seem to sinch down a zip tie tight enough for the life of me.

But as i said, it appeared to burn out all that bbuilt up oil when i took it out. I have much bigger problems on my hands now i feel. See my other post if anyone feels like continuing to help.

Thanks

You may simply have an air leak in the lines going to your VRO. Air leak in/around the VRO often leads to heavy oil mix. If thats the case it could just be unburnt oil laying around.

Those small lines could be recirc lines for oil to get to the bearings they need to be tight. Get the wire spring clamps to hold those tight and replace the hoses, zip ties won't work on them. Easy to tell if it's the fuel line take it off when you store it. If you have the new style tank it cannot vent out so they tend to build up pressure. Are you using zip ties to clamp all your hoses if you are get oetiker clamps instead and use them. Usually if the VRO has an air leak you will see excessive smoke out the exhaust.

Yes, i do have some leaky lines, ill admit. And only the lines i have attempted at re securing have zip ties on them. They originally had the OMC plastic snap clamps. Which were failing and equally as loose. But this is the 2nd time I've heard of such Oetiker clamps, i shal buy some.

Yes you need to take care of the leaky lines then check the OMC plastic clamps suck they break all the time. I just spent $500 on my new vro pump so I used all oetiker clamps. Also make sure you get the right size that is critical, to small and they break the the plastic fittings, to large and they don't seal.

I jus looked into them. Appears my local fastenal carries them. However, appears they require a special tool to secure them? Any way around it? Money is tight right now.
