My '76 Rx-4 hardtop build.

So its looking like the rx4 isn't going to make it to dgrr. Having some issue with the oil pressure. When it's cold it works great 100psi+ of oil pressure at 3000rpm. When engine temp hits just below 150 degrees Fahrenheit oil pressure randomly drops almost to nothing for a split second and then slowly comes back up. After that I can only manage about 85 to 90 psi max oil pressure. I've replaced the sender for my gauge, front cover o ring, rear oil regulator (fd regulator), front regulator spring shimmed 1/8", and oil cooler thermostat and spring. Guess the FC will make the trip instead this year.
