I ended up getting an oil cap breather and ran a line from the catch can back to the intake plenum with a VTT one way check valve. It'll pull the vapor under vacuum/idle and under boost keep the check valve closed allowing the PCV system to vent as needed through the catch can breather and oil...
This is UV degradation of the carbon fiber. This is essentially what happens when carbon fiber is exposed to sunlight without proper UV protection in form of Ceramics or quality resin when being made. UV light is to carbon fiber as oxygen is for rusting iron.
You can also take the OEM fitting and fit a barbed fitting on to the end of it to put a breather on it. The factory check valve on the block is actually a one-way INTO the block not out of it. However Capping it works fine as well. 👍
I ordered them on Amazon actually.
Are you running the PCV line that comes out of the block onto your catch can? The KLM fitting does not have the one way check valve in it, so it will just fill up the KLM can. Highly suggest removing your catch can and checking to see how full it is/emptying is. Guarantee its completely full of...
If you just cap/block the crank/block PCV fitting and run a VTT breather oil cap and compliment your PCV system with a catch can, you can just eliminate it all together. Those OEM fittings are fragile and super cheap quality.
On my top mount setup I just have it capped off.
Uncertain if this PFS pump is root cause at this point, but seems like PFS pump may either be maxed out or not operating to its advertised numbers.
Did logging on the dyno last night and were getting erratic fuel pressure and oscillation with fuel trim at the top end.
My theory is possible a...
Some people who have done PCV mods and added BOV have had seemingly good results I heard. Not a fan of the idea since we have amazing electronic wastegates on these from OEM, but I hope this is a good unspoken measure to help these hybrid/oem style mounts from burning up prematurely.
You might be one of the only ones who got a good/reliable unit. Glad to see someone is having luck with it so far. Have you done any PCV mods to help accommodate? (Visconti valve cover or PCV block pins)?
If you do buy, remove the CHRA and send it out to get an inspection and balance check. Usually some places will do them for $100. Better to have peace of mind that everything is all good than worry about it blowing or burning oil right after install.
it takes like 2 minutes to adjust them. Plastic cap and a like 16mm nut I believe. Just get a pry tool under the wiper arm and wiggle while you try to remove it and reposition. It can get kind of tight on there.
The only vapor that should be present is only excess from the fuel tank. From my understanding this system is only designed to allow it to recirculate to intake to keep the emissions down by burning it clean rather than into the air.
Yeah will probably go route of that. Had Botti but was trying to take advantage of saving a few bucks to get Marin to give me what he owes me. Would have loved to gone with Payn but the dude never responded to me on any form of email or IG. I guess he doesn't want to take on any new business...
To be fair when I say 2 CTS, it was warrantied, I have yet to send the 2nd one off....not even sure if I will. May just outsource it to get repaired and sell it or sell it as is to someone who wants to repair it or take a risk with it.
The dude literally promised me a free retune on the house since he screwed me on my original stock turbo e50 tune purchase a year ago, now that I got my new top mount set-up done he straight up has left me on read and ghosted me with just a base map. Sent him some street logs over 2 weeks ago...
