i have a built 418 engine with TVS2300,, i did my pcv system piping in the following direction using SMC dual catch can:

driver valve cover->SMC catch can 1->TVS vacuum port----passenger valve cover->SMC catch can 2->intake elbow

ventilation seems to be perfect and car drove way better but engine started to consume a lot of oil in short trips and found the blower fouled with oil inside,, what is wrong?

1- SMC system insufficient?
2- valve covers barbs not baffled or oversized?
3- piston rings?
4- valve seals?
5- TVS aggressive vacuum/boost?
6- ....?

please, help,, i have disconnected the system and put breathers on covers barbs and oil filler cap instead which i know not right,, btw,, breathers breath oil vapor and fumes while at idle,, no oil sprays whatsoever,,
