HI GUYS,
I am trying to replace an oil pump to a 1990 Honda Civic w/ a 1.5ci, 4sp
I removed the oil pan and found the p/u screen tube but could not see the oil pump.
Is this oil pump located further into the engine compartment? And is it something a wanna be mechanic like myself can replace?

The oil pump is located on the side of the engine where the belts are located. It is under the timing cover and is replaced much the same as the water pump which is located above it.

what is wrong with your oil pump, reason for me asking was that I was having problems with my oil pump in my 91 civic 1.5L. I had good oil pressure at idle but as I wouild drive it and the oil would get hot the oil pressure would slowly start to drop to the point that the oil light would come on. I went to honda and bought an new oil pump relief valve and relief spring frpm honda for 12 dollars and installed them which corrected my problem. If your problem is a similar condition all that is needed is to pull the oil pan and exhaust pipe off so that you can gain access to the oil pump. Then remove the 8 mm allen head bolt and remove the spring and relief valve and insert the new one. Good luck an hope this info helps

Suggested Repair

The oil pump is on the belt side of the engine, under the timing cover, and is replaced similarly to the water pump above it. If oil pressure is fine when cold but drops as the oil heats and the oil light comes on, replace the oil-pump relief valve and spring: remove the oil pan and exhaust pipe, then the 8 mm Allen bolt, and install the new valve and spring.

Conversation Summary

The owner of a 1990 Honda Civic 1.5 with a 4-speed removed the oil pan, found the pickup screen tube, and could not locate the oil pump. One expert said the pump is on the belt side under the timing cover and is replaced much like the water pump. Another expert described a similar 1991 Civic pressure drop when hot that was fixed by replacing the relief valve and spring after removing the oil pan and exhaust pipe.
