Solution: dirty valves and decarboning your engine.

No the absolute best way is to prevent the gunk from getting into the intake in the first place. Catch cans or as I term mine a condensation can will trap mostly all the blowby that normally is ingested and turns to carbon from the heat.

YES! I forgot about those, I am building an intake and those where right on the tip of my mind. Why would you wanna gum up the inside of a brand new intake? You dont, duh.

Prevention is better than cure.

I doubt it. You dug up a 3 year old post. Those guys have probably moved on to something else.

Yeah - catchcans are good, mmmk?

 

[moobypets]

catch can ?

 

[hawkeye18]

idunno, I just read the top of the second page here (I have mine set to 40 posts per page). It talked about catch cans. I installed one on my wife's car and it's caught amazing amounts of shit.

I gots two now.....

hummm interersting it like a second filter

thread rivival!!!!!!!!!!!!! but i never new this atf treatment... im doing it

 

[moobypets]

lol then keep me posted

And all the crap that was inside the can would've gone into the intake and engine and exhaust. That crap is why the intake is always so nasty and gummy every time you look inside it.

 

[SHOZ123]

Yes it is nasty stuff. About half water and half hydrocarbons. I found the more humidity in the air the worse it was volume wise. This stuff is what carbons up the valves.

oh this catchcan is only for the pcv line

would it not be easier to just put a filter and send it directly out the intake ?

 

[Off Road SHO]

It doesn't come out of the intake, it goes into the intake, FROM the crankcase. The whole idea of the catch can is to give the hot oil and water laden gasses a place to cool down and condense out most of the oil and water.

The SHO motor has a small condensing chamber on the back side of the block but that is not very efficient at removing the liquids.

Only if you can come up with a filter that can trap gases.

 

[moobypets]

no i mean outside like not sending it back into the engine at all

 

[SHOZ123]

If it is not connected to the intake for vacuum then you rely on the pressure from blowby to push it out. You no longer have Positive Crankcase Ventilation but Pressurized Crankcase Ventilation.

I have a small Parker pneumatic oil coalescing trap in the PCV suction line on my SVT Contour, it has to be emptied about every two tanks of gas. Coalescing traps will catch oil vapor and moisture, but you have to size them right, if they're too (physically) large for the flow rate, they won't be effective.

The V6 is very touchy about the PCV mainly because it does not use intake vacuum to produce the flow.

At one time I had a regular PCV valve connected to the large fitting on the back surge tank and I could produce a good level of vacuum in the crankcase while running, ~6" Hg or so. But you got whistling though the various PCV venturi ports in the TB.
