OKay so last week I started school at UTI in Avondale AZ. Well the courses I am taking are Automotive/ Diesel/ and plan on taking hydraulics and refrigerant to include the Industrial side.

Anywho. I am in class and using my Z specs on a worksheet. The problem is that the school uses some useless website. I also used their whatever to 81 oldschool Chiltons manual. I got most of what I was looking for except the info wasnt for and 81 but for 80.

I need the specs on the Lubrication System

1. Vehicle yr. 1981.
2. Vehicle Make Datsun/Nissan.
3. Vehicle Model 280Zx
4. Engine size CC/ or CU
5. Reqd Oil Weight ?
6. Reqd Oil Rating ?
7. Service Intervals:
Light Service ?
Heavy Service ?
8. Location of Oil Pressure Sending Unit ?
9. Oil Pump Type Rotor
10. Oil Pump Location: Located BTM of engine front cover
11.The Oil Pump is Driven by the: Camshaft?
12.OIL Pump Specifications:
13. Oil Pressure at Idle cold: HOT:
14. Oil Pressure at 2000 RPM Cold: HOT:

 

Check in the Haynes or FSM.

 

What is this FSM you speak of. If it is our zdriver search button, its not the info I have been looking for. Has plenty of specs like hp and tq but not lubrication info.

 

You should buy a Haynes manual... has all the specs you are looking for on page 25-27.

FSM = Factory Service Manual. Can be downloaded here: www.xenons130.com

 

I have one but after moving I am having issues locating it. I found my two other manuals for my pickup but as for the car manual I cannot find it.

 

I have two... one for the garage, one for the house. Another $14 might be a wise investment for you.

 

I will have to do that as seen I cannot locate mine. I have chosen to change the vehicle on the worksheet to my pickup. I only hope I can find everything I need.

I saw a built GM 355 at the school and I want it for my Z.

 

Here's some quick answers for you, from www.google.com and the Haynes manual.

4. Engine size CC/ or CU: 2393cc
5. Reqd Oil Weight? As in all cases... it depends on the operating conditions.
6. Reqd Oil Rating? SAE
7. Service Intervals:
Light Service? @ 1000, 3750, 7500, 15000, 30000 miles.
Heavy Service? When needed.
8. Location of Oil Pressure Sending Unit? Passenger side of block, near motor mount.
9. Oil Pump Type: Rotor
10. Oil Pump Location: Located BTM of engine front cover
11.The Oil Pump is Driven by the: Camshaft? No, crankshaft.
12.OIL Pump Specifications:
13. Oil Pressure at Idle cold: HOT:
14. Oil Pressure at 2000 RPM Cold: HOT: I don't have exact #'s... but 60psi+ is normal when cold. 30-60psi when hot.

 

For the oil weight I meant factory pref.

The reqd oil I was asking the oil letter code.
I think you meant API not SAE.

Thank you for the info you provided.

 

Hate to correct you nismo but the engine cc is 2753cc. not 2393

 

Maybe he has one of those special Zs

 

Ah yeah... sorry I was looking at the L24 specs.

 

Found my manual finally. Was in a travel suit case.
