My Pooparu hit 256,000 km (EJ255), and yeah it does burn an alarm amount of oil for me (almost 1L per 10,000 km). My GT-R doesn't burn oil and it's 1990 model.
So... car ran fine before. You changed a part, then car immediately runs shit. Do you revert what you did to see if it fixes the issue?
Oh and those people running vented BOVs have aftermarket ECUs.
R31 GXE - still have it
R32 GTS-t - dad crashed it
R32 GT-R - still have it
N16 Pulsar - sold it for below
Gen 5 Liberty GT wagon - dog hauler
You people change cars like I change underwear
