From the manual.....
Should not be below 50.7 psi at 2500 rpm. Should read 65 psi at 5500. Normal to drop below 14.5 psi at idle, but above mentioned values must be there. All values at oil temp 176F.

Does the 75 still have the 10 bar gauge?

Icepick may think he was specific, but he wasn't. A '75 2.7? A '75 upgraded with a 3.0?
The 2.7s had the 10 bar pressure sensor and gauge. The 78 on SCs had 5 bar for each. If you want to fool yourself, put a 5 bar sensor with a 10 bar gauge! |
