Anybody know what the normal oil pressure range on a 451 engine is? I've done a lot of looking and the only thing I have been able to come up witrh is the setting of the oil pressure switch (warning light comes on at 5 psi). Checked with evilution and he doesn't know.

I believe the US model 451 uses what smart designates as the 132 engine.

The numbers I find for this engine are as follows...

Oil pressure engine at operating temperature and idling: 0.6 - 1.6 bar (8.7 - 23.2 psi)

Oil pressure engine at operating temperature and 3500 RPM: 2.5 - 4.3 bar (36.3 - 62.4 psi)
