So I have a ton of oil being blown out of the VC breathers, this is not the "typical" amount of oil these engines are known to get in/out of the breathers. Here are the pertinent facts:
1 - Only happens while driving/under load, does not happen in the garage @ 5-6k RPM
2 - It is not the PCV Valve - blocked it off and tested it, issue was still there
3 - It is not ring blow - each cylinder has been pressurized with 150 psi of shop air and show no signs of leakage
4 - It is not the head gasket - same reason as #3
5 - The car drives/feels great, there are no drivability issues
6 - I had ~1k miles on the new engine before this issue showed up.
7 - This started happening on the drive home from Cottons where I had a 3" DP, 44mm external WG and 2.5" SS exhaust system installed.
I am in now way insinuating that install at Cottons caused the issue, just stating that a major upgrade/change occurred just before this issue occurred for the first time. Brian did an excellent job.
The only thing I can think of currently is that Brian @ Cottons mentioned that since the WG port on my turbo (GT6131) had some overlap with the WG port on the DP, I might get some boost creep unless I had the port on the turbo ported to match the DP. Is there anyway this could be the culprit?
Is there anything else turbo related that I missed that might be causing this? My engine builder is certain that the turbo is somehow causing this but I don't see how.
Thanks in advance.
