Don't have alot of space in the engine bay so I decided to make a smaller catch can than anything i could find.
Not the prettiest but doesn't look to bad. |

Ding Ding Ding..
It's a husky Air compressor filter from home depot.. I took all the internal shit out.. It works perfect..
Then you just need two 3/8" to 1/4" MIP brass fittings. I painted mine black cause i couldn't find any black ones..
Some 3/8" fuel hose.. Couple of worm gear clamps. Got yourself a compact low key Catch can.
Even got a nipple on the bottom to drain it.. |

Oil Catch Tanks collect the oil, moisture and blow-by gas that causes carbon and sludge build-up in the intake system and engine to keep them clean even under the hardest driving conditions. An oil catch tank is also an excellent engine dress up item that will give your car a racing image.
I did it for the racing image.. I feel 10 points cooler already. |

Usually your car feeds the blow-by back into your intake which cooks off inside your motor.
You wont notice alot of sludge in the can on your average N/A motor for the most part.... Usually F/I or high compression engines will produce quite a bit. |

VQ has some pretty bad blow by. Coats the manifold and starts to build up.
Hence why i'm throwin one in. |

| you should see how much I get in my intercooler, I have the same thing and it fills up every 3 weeks |
|
|
| STiPWR |
| Yes.... I would consider 10.6:1 on the VQ35HR high compression. |

A full sized catch can filled every 3 weeks??? Thats a little excessive. I would do a compression test, your rings are probably toast.
And having an intercooler full of oil is not normal. |

every srt is like that, remember the catch can is only 50-75 mls |

Yeah, thats a tiny catch can.
Every SRT fills their intercooler with oil though? I find that hard to believe. |

|
| catlin987987 |
| Ill, wait until the others guys come on and say that it does fill the intercooler really quick, |

it doesnt fill it,but after a year or so you will have about half to a full inch in there.our pvc valve is a piece of shit |

sounds more like a design flaw... engines shouldnt lose that much oil.. period... |

I'm not being a dick or trying to cause trouble but its a fact...
PCV systems arent designed to catch tons of oil.. they are designed to prevent crankcase pressure and vent gasses, not collect tons of oil due to blowby or inproperly setup systems.
Yes a more modified engine will produce more gasses and more vapors... but still unheathy engine = more catch can oil and if "they all do it" that cannot be good.
Thats like saying you have nice performance tires, but they bleed air out every day and you have to constantly check your air pressure and top it up every week, but its ok cause all these model of tires do it. |

It's one of the first mod people should get on an SRT-4 IMO (other than motor mounts).
It is a factory flaw, but a very simple one to fix though. |

I know I was taking it to an extreme level.. but it was to get the point across thats all.
I know all about filling up catch cans :P I've known plenty of people with boosted / broken motors that fill a can constantly. |

Tires have to do with safety of the passengers and keeping the car on the road. They're not even close IMO.

I do agree that it should not be that way to begin with, but it's not that the motor is damaged, or running poorly. It's a design flaw (It is a Neon after all). They do it from the time they leave the showroom floor. So you put a catch can on right away and no harm, no foul.
Also the extent isn't as severe as Catlin posted above (f'n noob). There's probably around a couple table spoons or so around each oil change. I'll admit that is a bit much, but not as much as I think you guys are picturing in your heads. |

The better ones are pretty well a solid mount, but they do have a thin Poly Bushing.
Some guys do just fill the stock ones with Poly, but IMO Solid Mounts is the way to go.
I'll try and find a pic of mine.
Edit: This is an old pic, but I still have the same mounts. You can see one at the bottom of this pic.

Completely different engine I know. But how is the solid on your car?
I had solid put in mine with the engine swap.. I like the response difference but down low in the rpm's.. With the new clutch and light flywheel.. I can feel drivetrain vibration through the whole car..
Gonna be rattle central. |

Design flaws as in your rings aren't seated properly? or they are worn out? because thats what blow-by is caused from. Unburned fuel and exhaust gases excaping around the rings into your crankcase. |

I would go solid with a FWD car.... You need all the stability you can get to prevent wheel hop.
RWD, I'd just upgrade my tires and buy a CF/Aluminum driveshaft and lightened crank pulley if i wanted better response. |

I posted a pic above. Do yours have a little bit of a Poly bushing?
There's was definately alot more vibrations after they went in, and also it will seem like there are more too, by all the extra noise transfered into the cabin now.
Since mine went in I can here every little thing. I can here the hum of my transmission while I'm driving, and actually even here the clutch of my AC pulley click on and off.
I'm used to the noises now, but when I sit in one with stock mounts, or even filled mounts, it makes me realize how loud it is inside my car. |

This is exactly what I'm noticing.. I haven't had enough seat time to get used to it. I'm comtemplating going back to stock.. But then i gotta shell out for the stock mounts again since the cock suckers never gave me mine.
Ohh and mine are completely solid.. haha. Its basically two solid metal tubes. |

And if the catch can is 75- 100ml thats 4 table spoons:asshole:
Like I said mine(and Travis, and Rons) fill up once every month or so(I may have exaggeratedevery 3 weeks its more like 4-6 weeks) |

If we want to be exact this equates to 5 to 6.67 tablespoonfulls.

Any Forced Induction engine you are going to have small amounts of blow by. That's why the catch can was invented. Not just for hurt/damaged motors.
If that's one thing the SRT-4 does have is a stout little engine, and very well made internals. There are plenty guys running 450+whp on a stock motor. |

Damn. That's nutty.
That's got to be pretty loud, and some decent vibrations transfered throughout the rest of the car too.:eek: |

No just engine |

|

I thought it was important to do them both since your motor will be torquing your bell housing more with the solid engine mounts and the tranny still being a bit lose sort to speak.
Thats what I read anyway. When I did my solid mounts, I also made a solid tranny mount. Same with my solid cross member bushings, did the diff mount as well just so... stress's are distributed evenly. |

I just put one of these on my car today, real easy:thumbup:
But the husky POS filter I bought, the bottom drain valve was busted. IE it wouldn't close, some silicone fixed that though. |

That's actually pretty common with them.. I sealed the drain nipple too. |
