ok this is weird to me
i just swapped in a 1995 B18b1 into my 1997 integra ls

started right up no problems what so ever about 20 min. later
i let the car run the oil light started to blink so i turn the car off
and check everything (new oil so oil level is good) i put a new oil
pressure switch and turn it back on same thing about 20 min. later
the light starts to flicker and so i turn the car off and right back on
and the light stays off for another 20 min. over and over again

i took off the oil pump (bought a used but good one from a friend)
when i took the one off the car i pulled it apart and it looks better
then the one i bought so i put the old one back on.

changed my ecu and i put thicker oil in there also and no change weird
thing is when the light turns on i restart the car and it takes it 20 min. to turn on again.

if anyone can help me with this i would appreciate it just thoughts you
might think is wrong with it so i can check it out

 

well first id say run an oil presure test on it see if when the light comes on the oil presure drops if its good mite be a bad sending unit.

 

put an oil pressure gauge on it, simple easy solution to find out if its the pressure or just a wiring problem

 

if you got good level then i would guess its an electrical problem. since you just swapped the motor you could have easily missed something..
i would check the wires first

 

thnx for the replys

wiring should be good because for the first 20 min. at a time
nothing is wrong until it flickers.

and yea i was thinking of putting a oil pressure gauge in to know
for sure if its getting low pressure when its flickering/on

any more thoughts on what it could be? just so i can fix it for when
i put the gauge in there and nothing is actually wrong

 

i would put a guage first just to make sure its not something mechanical

 

Without doing an oil pressure test. You really are going to have tough time finding the problem.
