Crank case breather

[rat4020]

I was wonderin what yu turbo Apex guys are using for your breathers , now my Apex motor is not in a sled and I run in 90 plus temps . On my last trip when I would run over 10 lbs of boost climbing the big dunes I would get a shot of oil out the breather filter . Any input would be great Thanx

I'm running an extended hose with a high enough loop that it doesn't come out. (Eighteen inches or so.) I've terminated the hose in a water bottle with holes to breathe. It was a quick fix one day that I intended to improve on, but i've never had oil in the water bottle and have had other issues with higher priority.

My Apex is in this. You can see the hose over my left shoulder.

Thanx for the reply : I can see the can ya made what I did was close only rigged up with pcv pipe and a K&N on top on my last dune trip . I think what needs to be done is a catch can "Sorta like the ones that are used on the turboed VWs were they got one hose going into the can about 2in up and they have another going out lower to the valve cover.But the set up I am gona do is use the catch can, but not run the second hose back to the valve cover but run a line out the top of the can and run it into a Morso crank case evap valve and then into my down pipe after the O2 sen . From the research I did the more crank case gases ya can pull out of the engine the more HP yer engine will make . I got a friend runnin a turboed Apex in a car like mine and he is using the Morso set up without the catch can and his will put out an shot of smoke here and there I think the catch can along with the evap valve will take care of the puff of smoke

I'm a bit worried about you guys pushing oil out the crank case breather hose. You shouldn't have that happen. Two reasons comes to mind:
1. oil Level slightly too high.
2. poor ring seal blowing too much compression gases past the rings.

On the sleds we use the hose from inside the Stock air filter, Connect it to the breather outlet, run it upwards and forward then Down towards the nose cone. If it blows oil in this configuration I suggenst point 1 and 2 stated above.

RX your #1 could have a bit to do with it the day I riged up my catch can I ran it for the whole day with no oil on the breather filter the next morn befor the day ride I checked the oil and saw it was just below the full mark and I toped it off and it wet the filter with in 1/2 hr when I went above 10lbs boost and got vert climbin the big dunes .
And your #2 ring seal .. pos but my motor has got about 850 sled miles on it and about 1500 buggy miles . Pos check compression maybe ? what do ya think . Thanx

 

[rxrider]

If it happened only once after you topped it off, and stopped when oil Level dropped Down a bit I wouldn't worry about it.
If it blows oil out the breather no matter what the oil Levels is, then you have a problem.
I would not worry about the rings unless you have exsessive oil useage or blow oil out the breather all the time.
I would recommend doing a compression test, if you are about even across +/- 15 % highest to lowest Reading I would not worry about it.

Awesome machines you guys have built

RX I have another bud runnin an Apex in a buggy just like mine and he had the same breather prob . His remidy was the Morso evap valve that sucks the crank gases back into the down pipe after the O2 sen and he also runs his res far below the add mark ,Which didnt sound like a good idea to me . I was also worderin if the hight of the oil tank could be a factor . The bottom of my res sits about 3 in below my valve cover

 

[rxrider]

The height of the oil tank is supposed to be at the same Level as it's in the sled or very Close.
I've seen oil tank moved on sleds due to turbo kits, they are at the same Level as stock or very Close.

 

[rat4020]

Thats great but could ya give me a picture of where the tank is supposed to be .Man I tore the sled apart four years ago and I have a hard time rememberin last week let alone four years age LOL. Heck I can hide my own easter eggs

You should be able to figure out from the pics the approx height of the oil tank.

This is from "rxrider's Turbo Garage" sled build thread, a lot of information displayed and explained

 

[rat4020]

Thanx RX the way the picts look the stock tank hight is about two or three inches below the valve cover mine is a good two inches above the valve cover .. hum food for thought what do ya think

 

[rxrider]

I do not think 4 inches will cause any problems

Do you have room to route the crank vent line upwards With a filter on the end, any oil should drain back into the crank, while excess air will blow out the breather.

 

[rat4020]

Man if ya look at my picts I routed the PCV can that I riged up a good 16 inches above the valve cover on my last trip . I am thinkin if I turned out a nice AL can and made some kind of bafflein into it .With eather a bigger filter or just do the Morso evap valve . Ya know I checked out the type of rigs that were using the evap valves and the majority of them were on the moded drift cars and turboed ricers. But I dont know a bud of mine that specs in Harleys said not to run a filter at the end just run it open ..... But ya know that dam sand does get EVERY Where. Like I said before it aint a lot of oil but a little makes a big frickin mess LOL.. I am gona do a comp test but the way it runs I dont belive thats an issue cause when I start it it burns so clean it spits out water out the exaust and its done that since 800 miles . If comp was an issue that would not happen . am I right ?

How about installing a Catch can on the line, oil pushing up the line stops in the Catch can and Return Down, then a line from the Catch can to the filter at the end of the hose.
This is how the RX-1 sled is set up originally, it drains into the air filter (it's mostly under vacuum in an NA engine).

I run my breather without a filter, but you riding in the sand... no way you want to run it without a filter of some sort.

Water out the exhaust is all normal, even the cars do that.
When you start up there is sometimes quite a lot of water in the exhaust pipe.

I am with ya . BLW RX Did ya check out the picts of the fine red neck catch can I rigged up on it my last trip LOL.. It got me by any ways
