cappedup Posted September 15, 2017 Report Share Posted September 15, 2017 Is my oil pressure too low? From cold 70psi. Hot, 2000rpm driving 55psi. Hot, 2000rpm stationary 45psi. Hot, idle at 750, 20psi. Guage reacts fast from starting cold, during driving, and turning off. I have noticed some cloudy stuff on the dipstick when cold, although put that down to repeatedly running engine for only a minute at a time recently. Condensation etc. Should I worry about that and investigate more? Seems to disappear after running. Was considering an oil/filter change even though PO said it was recent anyway. Fram spin on filter fitted. New car to me, only driven a few miles. Read about checking the pressure relief valve. Quick job? I'm happy there is 'some' oil pressure, and would only really worry if I was dropping to zero ever, but thought I would ask, in case I should be more worried than I am. Thanks for putting up with a ton of noob questions from me........ Quote Link to post Share on other sites
RogerH Posted September 15, 2017 Report Share Posted September 15, 2017 Hi, the numbers look not too bad at all. You will not get the oil up to temp in just a few minutes so you may find your Idle pressure may drop a little after some spirited driving. But I wouldn't panic just yet.

Roger Great, thanks for that Roger. The hot values listed above were after 30 miles of 'spirited' driving. Had to take the new dash for a test run, make sure it was working right. I had been reading about folks with 70psi hot, and wasn't sure how low it should go at hot idle. I'll get around to removing the sump soon enough, check out the pick up tube, pump etc. Thanks.

dingle Posted September 15, 2017 Report Share Posted September 15, 2017 Not to worry, the TR6 owners manual states that the oil pressure should be 45-65 psi at 2000 rpm, under normal operating conditions. Outside temps and oil choice will also affect it. Berry Quote Link to post Share on other sites
matttnz Posted September 16, 2017 Report Share Posted September 16, 2017 I hope very ,much that they're fine ad they're the same numbers as mine's had for several years... Quote Link to post Share on other sites

Your pressures are typical. Roger Quote Link to post Share on other sites
Nick Jones Posted September 16, 2017 Report Share Posted September 16, 2017 Those pressures look good to me. Some get slightly more at idle, some slightly less. Nick Quote Link to post Share on other sites
Tim D. Posted September 16, 2017 Report Share Posted September 16, 2017 Mine is 70 psi cold idle and 45-50psi hot idle Quote Link to post Share on other sites
