2011 pro oil puddle in belly pan

[iceman800xp]

Have a pro and noticed a puddle of oil in front of motor can't tell exactly where it's coming from but it's clean around the power valves. I think it may be coming out my exhaust. Just wondering if anyone else has had similar situation. It was about half or a third of a quarte of oil sitting down there.
Thanks for any info

Same on my end. Its just coming off the y-pipe to pipe connection. Check the grafoil seal to make sure the notch lines up with the y-pipe and if all else fails and you're like me (can't stand a dirty engine compartment) seal it up with some high temp silicone sealant. I used Permatex Ultra Copper and let it set overnight. Worked perfectly, no exhaust leaks at all now.

Thanks I'll give that a try and see what comes of it.

This fall i brought my '11 pro into the garage for pre-season maintenance and noticed the same thing. It is from the power valve vent hose that dumps into the belly pan. Silly/messy design by Mfg. in my opinion. Probably an EPA compliance issue though. Anyways, some people use a "catch bottle" to solve the problem, I just added a little extra hose, and vented mine to the outside on this sled, as well as the new one, to avoid the mess altogether. Works like a champ...no more oil

Cheers!

CORRECT BUT.............DONT USE A CATCH BOTTLE....that hose needs to 'breathe' and any bottle will not breathe like open air. We have elected to run that hose to the outside of the sled, preferrably the near the shock tower. If you dont believe me on the bottle theory, run a bottle for a few hours and then pull if off.

The sled will run noticeably better, and pull harder thru WOT. The back pressure on that hose needs to be atmosphereic pressure for the diaphams to work correctly.

The reward willbe seeing that oil blow-by on the outside of your new $12k toy.

Very interesting... Was this fixed on the 2012's?

Nope. Someone said it's probably an EPA issue, I agree with that. They probably aren't allowed to vent it to the outside as it would drip on the ground.

I ran a new hose over by the dip in the plastic for the chaincase drain. Very easy to clean up there.

I had the same thing with my 11 pro, cut a new piece of tubing a bit longer and drilled a 1/2 hole in plastic, pushing it through to vent to the outside near the shock tower. Still had oil inside and closer inspection had two of the three spring tab sets too close together to put enough tension on springs to keep y-pipe connection tight. Bumped them apart to get some more preload on the springs and seems to have gone away. Would be a good idea to use rtv as well as stated above to be sure.

outside

Any hoses venting to the outside of the sled run the risk of plugging up with snow dust and freezing off. You would have to be checking this setup frequently.

Back to the first post , we saw it on one 2012 pro and it's the y-pipe fit. Take it off clean up the donut and replace making sure the notches are correct then check the spring tabs might have to bend one to get a tight fit

Good call. In my haste, I forgot to mention that if you use a catch bottle, you need to have an "exit" for the air equal to or greater than the size of the one coming into the bottle.

Also, for BOTH applications (catch bottle or venting outside), make sure the hose is in a continual downward path so as not to let water pool in the low areas and freeze. This would plug the vent hose until it thawed out, and performance would suffer until it was flowing properly.

Any one using a vented catch can to collect the mess?

Amazing how many threads come up when searcing the Pro section with oil and belly.

And people say the search function sucks......

Throw leaking in with it and you still get 6 threads, wow......
