Nissan Repair: Nissan, Oil in Distributor cap, nissan altime, distributor cap

Question
I have done lots of searching and many different mechanics have different solutions yet none have worked. My nissan Altime (1995) stops while running for about only 5 minutes. I have noticed that there is only in the distributor cap. The distributor cap has been changed yet it still has the same problem. Please help!!

Answer
Evelyn,

It is not the distributor cap that needs changing.  The distributor itself gets contaminated with oil and that screws up the optical timing.  I would have the distributor removed and disassembled and then look at the optical shutter wheel, pickup and receiver and there is most probably oil.  If that is the case purchase a rebuilt distributor and you should be fine.
