Does anybody know what (low oil pressure #) causes the oil light to come on in a 65 ford mustang. My light comes on (sometimes flickering) and sometimes solid after the car in fully warmed up. I'm using 10-30 oil. Is this a problem, or is it normal?
I think it's 7psi. You should check that with a mechanical gauge, to be safe. Your sender could be bad, or gummed up. You can just pull the sender and plumb in a cheapie autozone or NAPA mechanical gauge right at the engine just to check. If it's ok, try a new sender.
Traction get's you a little way... Power get's you farther... Momentum get's you even farther than that... Put them ALL together, and you can conquer an empire! I am the emperror of that empire! I am the EMPERROR of MUD & ROCK & SAND & ASPHALT

Don't know the miles, I've only had it for the last three years. I get smoke on starting, but not much while driving or acceleration. It seems to have plenty of power, but oil consumption is high. I found that the pan bolts were loose so I tightened them, not sure if that helped yet though. I use 10-30 weight should I go to higher weight oil? Can the oil pump go bad?
A long time ago I had a 67 cougar, almost new 302 and I do remember the oil light coming on occasionally at a stop, but not all the time.
Try going to a 10W40 on your next oil change or if it is a fair weather car only a straight 40 weight if you can find it. When you get the light flicker do you check the oil? Low oil can give you a flicker under hard decel or accel if the pump slurps air. You may also want to check and replace the valve seals if the motor has lots of miles. Check the pressure as others have mentioned first because if the motor is worn bad then no point in wasting too much effort and cash though. Stu
No flickers under accel or decel. I will try the 10-40 with mobil filter and see what happens. How many $'s should I budget for a rebuild. I noticed there are remanufactured engines out there with warantees that go for $1,500 to $2,200 is that a good way to go. If I go to a local machine shop how much would I pay? I want a good street motor with a little more than average cam (in fact I have a NOS ford racing cam that is supposed to be one up from stock). Do I need to go to expensive pistons and rods to have fun on the street? The car is driven as a daily driver in the summer and occasionally in the winter. I have also put in a tci torque coverter and a shift kit in the c4.
mine turns on once its fully warm so i suspect the engine is pretty much done for,but i runs fine and doesnt smoke,but once its warm it makes a chattering noise which i suspect is the lifters.Do you guys think bad lifters are causing low pressure,or is the low pressure just killing the lifters??
