ECP oiled the clutches

[Mighty]

What would be the effect of leaving the cap off of the bottom and letting it drain on its own? would the carbs take in too much air through the hose decreasing the evac system for the the oil etc. or would it still be able to take in both and still allow the water to drain?

Your engine would then suck in un-filtered air.

I want to know what the new rings do in the 05's :ORC

I added the ECP and Evac at 300 miles - put 750 on in the last 5 days. Had frozen solid crap in the bottom 1-2" of the tube every time - I am assuming it contains some water - if so, why is water coming from my crankcase?

The kit performs awesome in the bottom to mid. I hadn't run a top end run yet as I was breakin it in before the addition so I am not sure what it would reach before installation. After install I am only getting 104 on speedo (over 1/4 mile hard pack run) - this might have been the case before install as well - might be because of something else.

kenlacy: With a four stroke you will have moister in the cases. Look at your oil after a long run. It can look milky like it's got anti freeze in it. Don't be fooled it's moisture.


What did you do cluthcing wise on your RX-1 with the Filters? I'm running a solid 120mph on the speedo on a icey road with Ulmer Clutching and ECP filter "no evac". On hard snow it will only run 110mph on the speedo.

I'm going to test the LP evac system and see if I get an increase. I'll post my results

I haven't touched my clutching - that will be for another time. Was just looking for a quick pcik me up. Was under the impression the ECP wouldn't affect top end MPH and it likely hasn't.

I just have a hard time swallowing the fact that my speedo wont read over 104 on hard pack and I am hearing others reading over 120 (I do realize this is not actual speed, but I would think I could get the speedo over 115).

I am not excited about clearing the ice out at every stop - I had to do it 3-4 times a day for 3 days straight - always 1-2" of solid ice/crap plugged up in there.

Want to pull the EVAC off now but then I get to hear about oil getting on belts.

Just trying to figure out my best option.

Make you drain tube longer....I made my evac hoses from clear tubing that I bought at Home depot.

I can see how much water is in the drain tube without removing the plug!!

I lift the hood once in a while and have a look.

Same as the 03 & 04's. Not enough!

I did blow out one of the half-moon shaped plugs on the valve cover gasket on the chain case side of the engine. It was because of a plugged evac kit. There is not enough heat from the engine to stop the water from freezing in the bottom of the tube, when you are riding at 10-20 degrees below zero. Couldn,t find a new gasket in central NY. Still waiting since last Saturday for one to arrive at my dealer. I will take the air evac system off. I never had it last year and had no problem with oil blowing out onto my clutches. Lost a planned trip to Canada this week, or the NY tY ride because of this problem. Time to go back to Polaris. 10 Polaris in 20 years, and never had to go to the dealer for a repair ever.

BIG BLACK WARRIOR: Your blaiming Yamaha for your mistake????

slit in 05 hose that comes out the catch. hope people are doing this if they use anything other than the stock hose (cut a slit in it), if not might not be covered under warranty.

The problem is definately NOT with the ECP kit...its with the engine. And it IS a problem. You shouldn't be getting as much crankcase pressure as we do with such a small motor. I own several 4.0 liter engines that get run hard, one of them a 4.6 stroker based on a 4.0, and the only crank evac they have is a 1/4" hose running from the valve cover to the intake, and that hose attaches to a fitting on the valve cover with about a 1/8" orifice in it. I have no oil problems with those engines. That PCV hose is what was used from the factory on those engines. I also work on a race car with a 1.8 liter engine that runs 6500-7500 rpms for long races, and it only has a 1/2" hose for a breather...and I don't think it even needs to be that big. There is never any moisture or oil in it.

1. You shouldn't be getting any noticable crank pressure because of combustion pressures unless the rings are bad.
2. With an inline engine with an even number of cylinders such as ours, we shouldn't be getting pressure because of piston movement because as 2 pistons are moving up, the other 2 are moving down, keeping crankcase volume the same. Air is moving around, but its not pumping in and out.

Water also shouldn't be in the crankcase unless its getting there by pushing past the rings (water from snow intake, and also from burnt fuel...water is a byproduct of the combustion process). If you are getting water in the evac hoses, then its another sign that something is wrong. And just because 10, 20, or 100 people on here say its normal, it isn't...just because it happens to a lot of people doesn't mean its normal.

This motor is spinning 10K plus all the time. The Water in the cases in condonsation. The problem with the motor is the Venting itself. Where is the 1/2 inch vent on teh motor your talking about? I'm betting it's on the Valve cover on the top on the motor.


I'm going out to the today to test a new Crank Case breather.

 

[Indy]

OK, here is my 2 cents worth. I don't understand why when we had a stock breather and the catch can, reservoir, and the hose vented back into the stock air box there wasn't a problem. We virtually have the same set up now with exception of not using the reservoir but the problem happens. The only thing that seems to be missing is the reservoir. Why not just include it in the EVAC system?

Please respond to this post.

 

[kenlacy]

The way Freddie explained it to me - and he should clarify if I get any of this wrong - is that the Evac system is generating significantly more of a vaccum than the stock setup due to no large airbox in between.

I assume, because of this large amount of vaccum, we are getting more moisture than normal.

Personally I dont like the idea of a 1"-2" plug of ice in the bottom of the tube every 100 miles of riding (that is what I am getting). That means this moisture is all getting pulled out of my engine.

I will likely dump the Evac but then I wonder about the oil on the belt issue.

I absolutley love the added low end and sound from the ECP setup so I am going to figure out a way to make it work.

 

[PARX]

I included the reservoir in my evac, still getting milky substance. Correct me if I'm wrong, I assumed the moisture was the warm air flowing thru the plumbing of evac or stock setup & swetting inside plumbing. What is the exact purpose of that OE reservoir?

 

[nhrxrider]

I still say, if you are getting enough moisture to plug an aprox. 3/4" dia. hose, there is a moisture problem somewhere. Air (and moisture) doesn't just appear in the crankcase needing a way out...if that much air needs to escape, then its coming from somewhere...thats where ring issues come in. That wwuld also explain the moisture, since water is a byproduct of the combustion process. Thats 2 different pieces of evidence showing that there is a ring sealing issue. Maybe not enough to reduce power and cause serious problems, but enough to create excessive crankcase pressures.

By the way, not sure of some of the others with opinions on this matter, but I have some experience here, as an ASE certified Master Engine Machinist, an ASE cert. auto technician, and a Chrysler/Jeep trained dealer tech. I do know a bit about engine internals, and about whats normal and not...and about what certain symptoms mean.
