Well I had a mildly successful day.

I put all the eye bolts in for my 5-pt Autopower harness. Too bad, I forgot the harness clip-ends (they came with non-clip ends) so I can't attach them. Harumph. It was the first time I had the front seats out of the car, so I vacuumed. Strangely enough, no french fries or anything else unusual, just all the dirt I've accumulated over the years (some of it surely from spinning at an HPDE a few years back...)

Then I removed the rear seatbelts. They're not much use since the rear seats are out.

Next I put in the Hawker battery. Hooray, it's small, it started the car after sitting for a few months in the garage. My old battery was kaput, it died after leaving the doors/trunk open for an hour, then listening to the radio for 15 minutes. Pbbbt. I have been really nursing it along for a couple of winters, so it was time to go. I got the battery at http://www.surplusev.com

Next up was this Moroso catch can I'd been staring at for a few months. I've been trying to figure out how to get the PCV to work normally with the catchcan in vacuum, and vent to atmosphere when the crankcase is in boost. Well, a few connectors, 5 feet of fuel line, 2 PCV valves and a little JB weld I'm in business. The crankcase goes through a drilled-out PCV valve (needed that size connector, but not the valve) to the catchcan located to the left of my battery, by the fusebox. From there, I have a rubber grommet on the top of the catchcan that goes to a T. One side of the T allows the crankcase to vent to atmosphere when the intake manifold is under boost. Under vacuum, the atmosphere one closes and the intake sucks air from the crankcase. Best of both worlds, but a little damn ugly! Hopefully those 3/8ths inch fuel lines don't collapse under heat and vacuum. If they do, I don't really care, PCV still gets vented.

Pics of the PCV coming, as soon as the wifey is off of my laptop.

Later!
Chris

p.s. regarding the bloodied hands, I dropped a seat on my finger (ouch), tried to drill a finger in my hand, and caught a flathead screwdriver in the palm while twisting one of the eyebolts in for the harness.

 

im having the same problem with my catch can... sure is troublesome
post up a pic
btw, sounds like you need a

 

Pics soon please

 

Well done Chris - sounds like a productive day. I spent some time today pulling the AC out of the engine bay. Sure is a lot of room in there now...

So, are you going to put it back in in the Summer?

Random crap I got at Pep Boys:


Drilling out the PCV valve that plugs into the block...


Finished, I think. Also check out the teensy battery.
(p.s. I am a hack. I don't care as long as nothing falls off.)
Edit, I should note: The PCV valve going to atmosphere is pointed "backwards" if you will. It will open up when the crankcase pressure is above atmospheric pressure. The normal PCV valve in the intake opens when the crankcase is above manifold vacuum.

Once I figured everything out and got started it wasn't that bad. I have a PDF file from Honda on the A/C install - makes taking it out much easier than using the Helms. Let me know if you want it.

 

Bet your J's is sagging now

Chris,

Good work. Your car is boosted? Did I read that properly? Hahaha....now I see the purple BOV.
Also...is that coolant I see all over the engine bay or dirty water spots from winter antics?

Aloha,
Brandon

Yeah, Greddy kit. Tial BOV you're seeing.

The splashes are salt water spots. Salt gets everywhere. I'll wash out the engine bay in a couple of weeks, it needs it.

Yeah, here's my dyno/setup:

why didn't you just put one of the lines on the intake side of the turbo? there the can will always see vaccum and will always pull positive pressure from the crankcase. MUCH simpler than rigging up a bunch of one way check valves, and much much cleaner.

It's a really weak vacuum that way, especially at idle (only as much resistance as what the air filter provides). I do already have the valve cover breather hooked up to the intake before the turbo.

hmm...every car i've ever installed a catch can on like that has gotten at least 10" vacuum at idle, and even more as you go higher into the throttle percentages. we've only seen vacuum losses of 2-5" compared to vacuum levels at the manifold. hardly enough to be concerned about. i've also never had any problems with excessive blow by due to high pressures in the case.

You might be right. I know this is a popular setup. Or you might need to clean your air filters, that's a lot of vacuum. I would think you'd have a LOT more vacuum after the closed throttle plate, than before it.

I like the idea of having a bit less crankcase crap in my intake while under boost... with my setup I only get the valve cover breather junk in my intake, and the crankcase dumps to atmosphere. *shrug*

so, as a catch can n00b, can you tell me how this differs from installing the can on an NA car?

Catch can is simpler on an N/A car.

Leave the stock PCV in place. Get some 3/8ths inch fuel line and route to the "in" part of your can. Get some more 3/8ths inch fuel line and run it to your intake manifold, where the PCV hose currently goes.

You can Tee in the valve cover breather, too... like 92TypeR

https://honda-tech.com/zerothread?id=622794

The difference on a boosted motor, is that the intake manifold can see positive pressure, holding your PCV shut, and your dipstick t00b becomes the path of least resistance for ventilation.

thanks.. exactly what I was wondering..

 

Here's another catch can n00b question, are there any negative effects of having a catch can installed?
