Ok. So before I tear this paxton apart, I was slightly educated on the pcv system. I have breathers on both valve covers with no catch can. I was told that I should hook up the supplied paxton pcv system so it can regulate crankcase pressure. Since I have breathers it's just always "full pressure"? Something like that.

They said that it's probably blowing past the seals because the crankcase pressure is too high because there's no pcv system to regulate what's going on.

Is this true? Or just a load of bull? lol.

With open breathers you will have less crankcase pressure, not more.

That's exactly what I thought

PCV pulls vacuum on the crankcase most of the time. It won't under boost. The 3v is designed to let air into the motor from the passenger side and have it go out the driver side. That's why the driver side is hooked up post tb and the passenger side is pre tb. When I had both my Paxton as a blow through and the Procharger I used a remote mounted breather on the passenger side and kept the driver side hooked up in the stock fashion. I did put an extra pcv valve on the driver side to back up the one in the valve cover.

That arrangement worked much better than breathers. Without the vacuum pulling from the driver side I noticed heavy vapors on the passenger side.

I've been told that how I had it set up would allow unmetered air into the motor. If it did it wasn't noticeable. I'd think that the amount would be a very small percentage when compared with what comes into the throttle body. Others on this site have their blow through setups configured in the same way. They also report that it works fine for them.

Alright. Took off the paxton. What do you guys think? Also there's no play in the impeller shaft or output shaft. But there is a little knock back and forth when your spinning it. I'm guessing that's normal from the gear to impeller gear.

 

[randys06v6]

Tore it apart. Rear seal had dirt buildup near it. Def a sign of it leaking. Front seal I do not know yet but there is no sign of a ton of oil leaking behind the impeller

Yeah the clicking back and forth turning the impeller is normal.

Thanks for reassuring me. I was having second thoughts lol

No problem, my Vortech does the same thing and initially I also thought it was an issue.

Still can't believe you sold my 4" cowl hood lol. Well yours I suppose haha

Lol.... I loved that hood, but the look I was headed towards, no spoiler, factory bumpers it stuck out like a sore thumb! Also, I got tired of driving behind it. Plus, you never sent me those damn relocated squirters!

I feel pretty dirty looking up your dirty supercharger hole, bro.

 

[randys06v6]

Ok pulled everything apart. A bearing came apart but nothing is broken. The plastic part that holds the bearings is perfectly fine too. Are you able to assemble these back together?

There's no scoring or any signs of damage

You have to install these a certain way because they will come apart I believe like this one did for example.

 

[randys06v6]

Just if anyone is curious.... To rebuild a thrust bearing, face the "thrust" side down of the outer race on a table. Put the inner race and plastic cage inside the outer race. Then, insert each ball one by one while tilting the inner race and plastic cage up towards each ball you insert.

Eventually you will get each ball in and the balls/cage/inner race will be built somewhat ontop of the outer race. Then, just press in the inner race and everything will pop into place. Voila!

Replaced the seals. Putting it back together. The impeller seal looked brand new though. Not a single flaw. The rear was def leaking.

Oil can't get into the system if it's the rear seal that's leaking correct?

I keep being told it's too much crankcase pressure, which gets pressure back up into the discharge tube of the supercharger and then blows past the impeller seal. I just do not see how if I have breathers on them. Should I go bigger breathers? I just bought 2 catch cans that I'll put on and then to a breather.

Should I just route the pcv system back to paxton spec? Or just leave it and assume the impeller seal went bad even though it showed no signs of wear and tear

 

[eighty6gt]

If your crankcase isn't connected to the intake tract except via past the piston rings and valve seals I can't see how it's pressurizing it.

I'd run a real PCV system anyway. In the passenger side, metered air, out the driver's, into a bob's catch can or whatever actually works, then into the factory intake. Paxton must supply a one way valve.

For anyone wanting to replace their seals, a great place to buy them is thedubnutz.com

Same size and is actually stronger material than most other seals you will find. Even over 982 motorsports. The spring is made out of a stronger metal too.

Best thing is its cheap! Lol free shipping too! They are based out if new York
