figured, so would the most optimal if Im not worried about emissions be to tap both my intake and exhaust breathers to AN, and run them into a catch can that vents to atmosphere.
hey everyone. it's me, yet another "too much oil in the catch can" guy who stumbled upon this thread. ever since installing the TDR C30-94P kit on the car, i haven't been using the PCV hole (capped the PCV). i can barely make it 40 miles staying OUT of boost before that thing starts overflowing and dripping onto my headers. so in a fit of being sick of it, i took whatever i *remember* reading from this thread and made some holes. (edit: i'm also planning on reusing the PCV side to route another hose to the can after reading all these posts).
going from the center chamber to the first exh side chamber i enlarged the hole to 3/8" but then staring at it i didn't think it would do much if the hole was nearly flat against the baffle plate. i'm not planning on slurping oil out with vacuum, so i whipped out the die grinder and roughly 45 degree'd that thang. and for extra good measure i added two more holes, a 1/4" hole on either side of it at the same angle. for the holes going from the first chamber to the second chamber of the exh side baffle area (i think my valve cover is a '96 so it's not all just one chamber) i did basically the same thing but with a couple extra 3/16" holes beside the 3/8" hole.
i've been awake for about 32 hours at this point and maybe i'm a genius or perhaps i'm just really dumb, but now i'm wondering if this only works for a while until that baffle chamber fills up and the oil has nowhere and no-how to drain back into the head and i start rapid filling my can again. so here's what I'm wondering... should i drill some tiny holes here (i had just taken the VC off in this picture) where the baffle plates have these dip things so the oil can drip back into the head? what are your guys' thoughts...
I read the entire thread and I’m still so confused. Never had a catch can setup on a car before. Just recently picked up this boosted 1.6, makes 225whp on 12psi. Literally had the car for 3 days and I’m 99% sure I blew the rings in the two front most cylinders. I was in boost for about 4 seconds in 5th and once I got around 5.3k rpm instantly felt the car lose power. Two front most cylinders not firing and hear a clanking noise from one of the cylinders. Pretty sure I over boosted the crankcase and blew the piston rings. Oil residue all over the VC and oil cap. Oil all over the spark plugs too. Have yet to pull the head, VC or anything.
Made a fb post and someone pointed out the catch can system, the PCV valve and IM being capped off. After reading this forum completely it seems like this is not an optimal catch can setup (bought the car this way). Again I’m still so confused as of what would be the best system to decrease crankcase pressure in a 1.6. Any help would be much appreciated.
Rings are literally sprayed in oil and wipe it away every time they go up and down, they can survive a bit of oil. More than likely they're compromised with poor timing or fueling. Would love to see a datalog of that pull (probably in another thread) if you've got it.
That being said, no your setup is not ideal. I'd run the catch can back to the intake (pre turbo) rather than being VTA. I'd uncap the PCV and run it through a check valve, then catch can, then to the intake manifold.
Well, i did the tiny hole thing on the exh side plate and gutted the PCV to be able to route two hoses earlier today. I'd like to do the whole AN fitting thing, but alas, for now, I have this. I'll post an update with the results later.

this is where i thought up the idea. lack of sleep i guess? well, anyways... i'm here to say that everything I've done has worked. i went from overflowing in under 50 miles to putting a full tank of gas through her now with only this much to show for it:
