[DeTomaso] Oil Pressure Sender

[CharlesMcCall]

As long as we're comparing pressures, I installed a mechanical oil pressure
gauge with a T fitting in the original lòcation. 

The stock pressure gauge registers about 70 when cold, while the mechanical
registers 80psi.

When warm, the mechanical gauge reads a rock steady 60, while the stock
gauge reads anywhere between 45 and 55, with occasional really weird
readings, which is why I installed the mechanical gauge in the first place.

I have standard oil pumps in both my Pantera and my Longchamp. The Pantera
has 40-50 PSI on start up and when warm on highway rpm. For the Longchamp
it's above 70, like yours. When the Longchamp idles warm, it goes down to 50
PSI, so it's not shorted

Pantera: K&N 3001 and 10W-40 Royal Purple Synthetic
Longchamp: crummy cheapo filter and no brand 15W-40

I don't know if the filter/oil difference is the reason or the gauges are
different? I've decided not to worry about it...

Mvh/Regards
Mikael

...or, you have a high pressure oil pump that is generating excess 
pressure.   My motor showed 70 psi at idle at startup; it would drop to
about 60 psi 
once the oil warmed up.
