oil and cooling problems
my 86 oil pressure reads between 0 and 2 when it is idle and when i put it in drive and give it gas the oil pressure goes up to about 15 to 16 psi but drops when i stop or put it in park, oil pressure only stays up as long as i hold the gas. What could be causing this and what is the normal oil pressure it should be reading? also my coolant temp reads about 250 which is within the norm and when i give it gas while in drive the temp sinks to about 220 - 230 then steadily increases until it goes over 260 and higher which is overheating. this cooling problem happens in both park and drive and with the engine idle as well. what could be causing the coolant to do that?

well 8 yrs ago up until my brother messed up the distributor it never had these problems. trying to resurrect the car. i suspect that the coolant going up and down may be due to my thermostat stuck closed plus i havent flushed out the radiator yet.i got a water pump ready to be installed. i just finally got the car to run and stay running after numerous replacement parts i got for it. the only problems i have is the coolant temp, oil pressure, and finding out how to make the car start on the first time rather than pumping gas into it then start up fine after wards until i turn it off and leave it there for at least 8 hours.IM pretty sure this is my tps, but im trying to figure out wat to do about my cooling and oil pressure mainly.

I would remove the oil pressure sender and install a mechanical gauge to verify those low numbers, first.
Pull your stat, STAT !!
, if it's stuck closed, nothing good can happen.
High engine temps will lower your oil pressure. Might be part of the problem.
Dose your cooling fan operate properly ??

I've heard there is something in the oil filter that can cause this. If memory serves me right the use of RTV clogs something in them ... sorry just cant remember what the issue was, anyways this can lead to the low oil pressure your seeing and the sender itself.

well i changed the oil sending unit and replaced the stat and it runs like a champ now. finally after 5 months its in good mechanical and electrical working order, now all i got to do is cosmetic work, at least now i can finally drive it.
