Well boys it was fun while it lasted ? *A new challenger has appeared!* Spulen V2 PCV plate decided to suck liters of oil out of the head, causing low oil pressure and sending all that oil back into the turbo, destroying it on the 2nd day. Timeline:
Friday (Nov 8th) and before:
- We did several street logs for tuning adjustments before the dyno tune session, all while using stock/OEM PCV with no issues.
- Night before dyno tuning session (Thurs), I throw on Spulen v2 PCV plate
- On dyno (Friday), tech finds the catch can is full after 2-3 pulls (WTF!) We suck it out and complete dyno tuning, netting 522whp/440wtq on heartbreaker dyno
- I'm hoping it's some weird condition with being on the dyno
- No time to think about this, already passed time commitments to get the car on a transport, split with a buddy, to ship the car up to the racetrack, 4.5 hours north (Hallett), which is why dyno was cut short (since they took 1.5 hours just to get it started). I pack my OEM PCV just in case
Saturday:
- Track day starts on Saturday. Having a great time, but find that the catch can is full after every session, so I have to empty it after every session
- No smoking however
- Finish day, no real issues noticed, but didn't REALLY check everything over (regret, but was exhausted)
- Buddies telling me they know big turbo people and they fill the can all the time so I don't really put a ton of thought into it other than "I'm going to have to fix this later because this is ridiculous having to dump this thing after every session"
Sunday:
- 2nd day, get a random low oil pressure fault, restart car and it's gone, go through session 1 "fine" but notice boost is a little inconsistent
- Session 2, boost is starting to really get inconsistent, after 3 laps go into super limp mode where you can't rev over 4000 RPM, we were planning to leave at noon so I call it a day at this point
- Find that catch can was FULL after only 3 LAPS, meaning after just a few pulls, the rest of the oil was going straight to the turbo! And I had tracked hard 3 sessions the day prior
- Find CEL fault for camshaft position along with boost faults, so thinking low pressure caused tensioner to lose tension and timing jumped
- Pull off intake and find:

- Turbo definitely botched at this point but no choice but to try and drive 4.5 hours home with it
- Babied it and made it 2.5 ? but turbo finally seized and I lose all power... trailered home hours later
- Pull off turbo this past weekend, plenty of shinies in discharge pipe, shinies in oil filter, and exhaust camshaft timing is off by a tooth (good since it's not enough to damage anything, bad because I have to re-do timing)
So yeah, that was my track weekend, trial by fire, right? Everything was great.... and the supposed end-all-be-all Spulen V2 PCV destroyed my car.
The good news is Dan is going to repair my turbo for free, even though the turbo isn't at fault. Pretty cool, and that was my main worry. Everything else is just time. Turbo is already off, shipping tomorrow. I have to pull my entire charge system out and thoroughly clean it. Have to re-do timing, again. I've got a few months to get it done since it's going to be too cold to enjoy the car anyway.
Honestly I had a f'kin blast and am not too upset thanks to Dan, and my buddies driving an hour and a half with a trailer to get me. It was a terrible day that was saved by the kindness of good people.
