If you take off the oil pan, get the RX7=C2=A0oil pressure regulator and bring that psi back to 100psi where i= t belongs. The first gen (2004-2008)=C2=A0of RX8 messed up and went with lower oil pressure (80psi). They fix= ed that in the second generation, but an easy=C2=A0mod is to just get the R= X7 reg.
