Icebear 150 spewing oil. Help?
« Thread Started on May 7, 2011, 11:43am »

Ok, on the way home yesterday something happened. When I pulled up to my house, I had oil all over the back of the trike. dripping from the engine area. I don't know what happened, and am hoping for some ideas/help/advise.

The only thing I can find possibly wrong is one single line. I'll describe it. The end has some sort of inline looking connector, but I can only find one hole it might go in, but it doesn't make sense as that is into the bottom side of the air intake and looks to be possibly before the filter. It's in the white plastic piece, not the black hose that goes into the engine. The other end of this hose is in a Y. One side goes to the front of the engine on the top driver side corner of the front of the engine. The other side of the Y goes to a black box mounted to the driver side of the frame. I have no idea what it could be for. I see no cracks or broken areas on the rest of the engine. The oil starts about half way back on the engine, and spreads further out the further back you go, which would coincide with that hose whipping around while going highway speed and being pressurized. Like a fire hose with no one holding it. I have no idea what this hose is for. I cranked the trike and didn't see anything coming out of it. Made me think maybe gear oil? I'm not even sure this trike has gear oil. Again no real scooter experience. I checked the oil and it still shows full like it always has, which sets oddly with me as loosing the amount I did should have made it at least low. Yet pulling the dip stick and rechecking it it always comes out full. I did have the trike to it's fastest ever yesterday, approaching 65mph on a downhill. Could that have done something? Maybe sent the engine RPM too fast. I really wish I had a tach to keep track of such things.

Anyways, I'm naturally scared to run the trike until I've fixed the issue. I was thinking maybe a blow back or something due to excessive RPM. Still with the engine oil not showing to be low, I don't know. Anyone have any ideas? I'll be available to check them immediately today. Also if pictures are needed, they can be provided.

Which Trike do you have?

If you changed the OIL you could have over filled it and blew out the overfilled oil. That hose from the top of the Valve cover is a VENT line which can throw oil out if to much pressure it built up in the Crankcase. Make sure that line is NOT CLOGGED or KINKED. Wherever that hose goes to is probably full of oil and it came out. Also there should also be a VENT hose from your Tranny usually right above the CVT where your Clutch is .

Take a picture of what the connections and hoses. Yours sounds like it has some emission canisters.

No, I haven't changed the oil yet. I actually planned to this weekend. I'll get some pics up here in a minute.

The trike is an 2010 icebear 150cc. Under roketa it goes by a MC-102. Under icebear it's a PST150-11.

Ok, there are a few guys that have the -11 trike one guy is WILDMAN on here and he is also on ScooterDoc.Com forum as well. The 150s all have the same engine so I know it very well I have the Ice Bear PST150H trike.

Ok pics.

First this is the end of the hose I suspect. You'll see what I'm talking about by the red circles and boxes.

Here is the Y in the line.

Here is the line coming out of the front of the engine.

Here is where I suspect the line went into the air intake.

Here is where the other end of the Y goes, the box I mentioned is marked by a red box.

What I would do is disconnect the hoses at the "Y" and only leave the hose from the Valve cover and TAKE the PLUG out of the end of the hose THAT HAS TO BE OPEN otherwise it builds up to much pressure in the Crankcase. Put a Fuel FIlter on the end of that hose and tie it up High on the frame so that if it squirts oil out it will drain back into the Valve cover and go back into the Crankcase.

Ok run that by me one more time. Disconnect the hose from the Y that runs to the black box, and the one that runs to the plug then put a fuel filter on the one that runs from the front of the engine to the y? Then what does that black box do? Don't I need it for something? Any idea where that single hose ran to? I'm trying to understand what's going on as well as getting it fixed. The more I learn the less I have to ask.

Ok:
1. The Hose coming off the VALVE COVER is a VENT hose-- THAT has to be open and not Plugged up.
2. Take the Hose Valve Vent Hose and put a Fuel Filter on it and Tie it up HIgh on the frame.
a. If oil squirts out of the Valve cover it will travel up the hose and into the Fuel Filter and drip back down into the Valve cover.
3. Anything else you can disconnect from the "Y" connector YOU DO NOT NEED the "Y" connector anymore. Just run ONE hose from the Valve Cover put a Fuel Filter on the End of it and tie it up high on the frame. It will Breath and not throw out oil.

The Black box is just an emission box to trap fumes and in your case probably oil that squirts out of the Valve cover. But the problem with those is if they get to much oil in there they do not let the Crankcase Breath through the Valve Cover Vent.

Thanks lefty. And thanks for directing me to scooter doc. You and they are both very helpful, and make me feel so much better knowing I didn't blow up my trike! I was near tears when I got home. Just getting used to it and it blows up!

I already have plans to switch to an K&N filter and a Dr Pulley variator as well as the Kenda taller tires. I'd die if I had to instead spend the money to send off for a new GY6.

Weird, the diff does all the oil slinging on my trikes

That's probably what he was seeing too.

Have you noticed any lost in power, specially going uphill? If it's a lot of oil your loosing and you have to top off the engine oil every 3 days or so depending on how much you ride, that means the oil is being pushed out. This happened to me, it was one of the valves that wasn’t closing properly (I think it was the intake valve). I just reseated the valves and problem solved. No more oil spill and got my power back.

BTW Lefty I love the gas filter idea I think I’m going to try that. I’ve been thinking of installing a free flow air filter and I didn’t know what to do with that hose

Sorry I didn’t read the part where you said, you’ve reved the engine so hard. I don’t know if it's normal, but it used to happen to me, like a long time ago way before I’ve noticed any lost in power it only happened when I went really fast downhill, so it might not be related with a bad valve, just some extra compression trying to get out or something. What you need to do is to open the air box check where that hose was depositing all that oil because is full, in my scooter is a sponge that catches all that oil you need to remove that sponge and squeeze that oil out (then reinstall it if you plan to keep the same configuration), also clean the rest of the air box, there should be no oil in there, you don’t want an oil clogged air filter, then you’re set.
Monitor the oil more closely now like I said before if you notice any of the symptoms that I’ve mentioned , power loss and oil loss through that vent hose, then is a valve that is not closing properly.
Cheers.

i also have a pst150-11 with an aftermarket uni filter. i left the hose hanging but noticed that the bike was just not running right afterward. The bike was running soo lean that it was back firing on deceleration, and i also had to crank the idle up just to keep it running. I suspected the hose to be the problem, but when i put my finger over it i noticed it had actually had a vacume to it. Once plugged the bikes idle went back to normal and no longer runs lean. Sounds like im not supposed to have this line plugged up, but how do you keep it from sucking air back in it?

Mine's still hanging and it's running great since I re-jetted the carb to a 100 jet. I like Lefty's suggestion from another thread of putting a fuel filter on the end of it.
