I have a stock 74 TR6 with 87000 miles and I do not believe the engine has
been rebuilt. I cleaned out the radiator and redid the cooling system. The
other week I drove the car all day in 90-95 F weather at a 40-50 MPH pace,
2000 to 3000 rpm. The oil pressure was <25 at idle and rarely hit 50 psi.
I thought it was time for a rebuild and new oil pump. Later I drove it at
the same speeds but in 80-85 F weather. The oil pressure at idle was 25 and
was >50 at 3000 rpm. The car ran at normal water temps on both days. I
guess the difference in air temp caused this variation in oilt
temp/pressure. Now I am thinking maybe I should put in an oil cooler and
put off the rebuild a few years/thousand miles. Any comments?
