Apex turbo Keeps Blowing Secondary Clutch Seal to the Crank Case?

My Apex Turbo on 12 pounds of boost with a Boondocker Turbo keeps blowing oil out on the clutch side soaking my belt and whole engine on that side. I think it is blowing oil out through the crank case seal on the seconadary clutch? Any help? New seal installed correctly made it less than 2 hours if that is the case.
 
Are you talking about the primary clutch seal? Are you sure your not pressurizing the crankcase somehow?
 
There is no crank case seal behind the secondary clutch your not even close to the engine do you mean the primary clutch? Check the gear reduction cover behind the primary clutch and make sure all bolts are in there. I had a bolt back its way out and it sprayed oil all over the primary clutch and belt.
 
if alll the other stuff checks out good, run a compression test,I have seen blower motors(cars) burn pistons and cut a groove right past the rings and they pressurize the crankcase and blow seals....yet still sound good running wise...
 
BD kits are notorious for blowing oil out the crank case breather hose. Follow your breather hose and see if it's routed where it will blow oil onto your belt. You may need to re-route the hose to the front of the bellypan and provide some kind of catch bottle. This is worse over 16 pds boost. This problem will be much worse if your motor was broke in on synthetic oil because your ring never seat properly. This will happen even if you don't have engine problems, but can get worse if you have ring blowbye. It's an issue to my knowedghe BD has never owned up to or taken ownership of and found a fix so you probably won't get much help from them.

I would be very surprised if it was coming from your primary crank case seal, but I suppose its possbile. As has been stated there is nothing on your secondary that would have anything to do with oil.
 
Also make sure none of the hoses coming into or out of your oil tank have any kinks. The main hose that runs down the back of the tank and into the crank case can get kinked pretty easy. I had to put a long spring inside mine to keep it from kinking.
 
Leaking oil on the clutch side

it appears to actually be at the gear reduction case gasket that is leaking,,, I think. I had a new seal put in it the other day and I am still having oil on that side and it is hard to trace as it blows everywhere with the clutch spinning. Breather tube maybe is my only guess as well but mine is cut short and up at the frame rail at head heat and has a K&N filter on it. Hairline crack maybe hard to see if that is it but the shaft looks fine to me? Any other thoughts?

there must be oil behind the seconary Clutch shaft where that bearing rides is there not?

I have looked at all the bolts and thay appear tight. I have a dropped and rolled chain case so that probably does not help me any in finding hoses in the back of the motor.

How many breather tubes are there that i should be able to find?
 
There is a greased brg behind the secondary clutch thats it, no oil. You could get a catch can that mounts to the handle bars below the hood, breather hose from left front corner of engine runs up to it. Then blow by, oil, runs into valve cover thru were filler plug is. There is a couple companys that make kits for RX1, Apex, etc.

Think you could point me in the direction of what company that is?
 
I'd say it is your crankcase breather, your getting blow by, i extended my crankcase breather hose to the front of the bellypan and fished it into a coke bottle, also on the boondocker kits it helps to get your rpms to 10,200-10,400, less pressure buildup in the block, i can take long pulls all day and then check my bottle at the end of the day and only have a few drops of oil, the rpm thing is big on these kits.
 
I got mine from the link that was posted. Lightning Pro, seem to work ok, but I dont have a boondocker kit. I have engine issues, thats why I got one. But the engine is going to be repaired, too much boost without enough good fuel. Not sure if there still in business, but thats the only company that really build a front mount turbo, its in front of the engine. I even found the bill march 23/06, so it was awhile ago.
