My PCV experience with 8 track days in a '16 GTI this year is summed up as follows:
- Replace OEM PCV as soon as possible
- Don't buy the BL OEM plate, terrible blowby worse than OEM (I've got one to sell for cheap!)
- Get Spulen V2 or new APR CC ideally if it ever ships (anything with a new plate), VWR is last in my list
- With the new PCV plate and CC, no oil smoke/starve/minimal loss
- iAbed baffled oil pan is great and helps with additional oil starve and blowby mitigation
- Get an oil cooler while you're at it, necessary for track use
This week I had a track day with 1:40 of WOT track time and measured 8oz (~0.25L) of oil in my Spulen V2. Reaching out to Issam at iAbed to see if there is an ideal dipstick range so that I'm not overflowing the pan as well as my first session filled the Spulen about a third then it was minimal from there.
Plan is to swap out the Spulen V2 for the new APR full CC when it ships which should be even better based on tester reports.
In my opinion, everyone should get a PCV plate replacement and oil cooler for the track. iAbed pan is a nice-to-have that adds confidence in lateral G sweepers and also lessens the oil starve/blowby issues and for me is still worth the cost, it's a great product.
