Right-angle PCV Valve

[Calan]

Does anyone know of a right-angled PCV valve from another motor that will fit our 4g63?

That straight PCV valve that ends up an inch from the TPS and in the way of everything has to be the most retarded design ever.

You have to fabricator your own PCV valve or do something like this:

I've thought about relocating mine in the past - I absolutely hate where it's at too. If you find a right angle PCV valve I'd love to get in on it!

Craig (and all else). Remember that the PCV valve has a snorkel that extends away from the walls of the VC to keep oil that runs down the walls from getting sucked/blown through and into your catch can, check valve, or intake manifold, depending on your mods.

In theory, you could drill and tap a new PCV valve mounting spot on the passenger side of the VC (next to the breather maybe, but not too close...wanna force that ventilation at idle, but if the breather and PCV valve are side-by-side, you may not ventilate as well) and clean up the fuel rail area of the engine bay (Craig's mission, as I understand it ). But who knows where the oil splatters under those baffles...might have given the Mitsu engineers headaches and led to that specific location. As I like to say, "Throw it against the wall and see if it sticks." Drill and tap takes no time. If you see too much oil in the PCV line, let us know so we don't do the same stupid thing as you .

Being as frisky and adventuresome as Craig is, he could fab up a 90-degree fitting with a snorkel (braze or jb-weld some brass tubing into the end of the fitting) and re-use the stock PCV valve location...as long as you can clock the fitting in the desired direction. He can use the USPlastics check valve (probably has 20 of 'em already) to satisfy that role of the PCV valve. The only missing piece then is the metering orifice of the PCV valve, which might be compensated-for by the ISC at idle. Or he could put an OEM PCV valve in-line but outside of the VC somehow to handle idle metering.

Go show us what-for, Craig!!

... yep... that sounds like me.

I know what you mean by the snorkel Mack. My thought was to find one that has the snorkel, but has a 90* outlet.

I'm seriously thinking about cutting and rewelding the nipple, or trying to get a tubing bender on the existing one. Even a slight angle would be better than straight towards the TPS.

OT, but I hit a milestone tonight on my build. For the first time since last November, it has life! errr...sort of; power to the ECU, stereo, and all the sensors/fuse blocks at least, with no smoke or flames...yet. .

Now I just have to get a suspension in it, axles, wire up some fans, build oil cooler lines, design and build the new catch cans, fill and bleed all the fluids...and on...and on... and...

I may just say to hell with the rest of it...just sit in it every now and then and listen to the stereo...I forgot how good it sounds

Ask and you shall receive!

I figured it out, and posted up a tech article

How to make a 90 (or 45) degree PCV valve

Enjoy!

That's perfect Craig - thank you very much!

 

[kenamond]

Sweet!! Turned out absolutely perfect!

 

[Calan]

For future reference....I've updated the article to include a 45 degree version.

Nice update! Was the 90 degree one a big PITA to get the hose off of?

Do you mean the rubber hose connected to the PCV, or are you talking about removing the snorkel that I pressed into the elbow when I switched to a 45?

Accessing the rubber PCV hose wasn't a problem...I just switched to a 45 degree angle because it routes the hose exactly where I want it to end up with my new catch can setup. (I'll have pics of it in the next one or two blog entries). The 90 degree elbow works fine also.

As for the snorkel that's pressed into the elbow... well it's not going anywhere unless you do some serious coaxing with a torch and vice grips
