Ford Dealer & Service Field's take on Oil Gauge
 

Today is good day to read some of my period magazines. I came upon this from the Ford Dealer and Service Field. It seems they are saying an oil gauge is not necessary, but add one to appease the customer... Did Chevy one up them and/or is this just sales talk? What say you?

"“Oil Gauge on Instrument Board”

OWING to the fact that the six cylinder Chevrolet oil pump has to distribute the oil through numerous pipes and raise it to the top of the cylinder block to lubricate the camshaft, the Chevrolet engineers have added an oil gauge on the instrument board. With the Ford oil pump located down at the bottom of the crank case, (Where it does not have to depend on suction to raise the oil to the pump), and with a gear type of oil pump capable of high pressures, the Ford engineers have not considered an oil gauge necessary on the Model A Ford. IF the prospective buyer of a Model A Ford does desire an oil gauge, there are a number of makes of reliable oil gauges Which can be quickly and easily attached. A connection at the side of the Ford cylinder block seems to have been designed for just this purpose.""

Where is this connection?
Being a visual kind of guy, a pic would sure help.
(Not that I plan on installing a oil pressure gauge)

On the oil pump bulge on the block. Sometimes used to hold the oil pump in place when dropping the pan.

I think either case for 'have' or 'not have' an oil gauge would be valid. It does give a warm and comfy feel to have one though.

The model A oil pump is driven by the camshaft and carries oil up to the valve chamber where the oil travels by gravity through passages in the bottom of the valve chamber down to the main bearings and cam bearings . the rods are oiled by dippers that dip the oil from a dipper tray . There is very little oil pressure and no oil pressure to the bearings . There is maybe three to five pounds pressure when warm that can be measured if a tube is attached to the slotted plug on the right hand center of the engine block , just above the oil pan and connected to a pressure gauge . The pressure can maybe be as high as 15 psi when the oil is cold and thick . When driving the car an oil pressure gauge would be usefull to show that the engine had oil . The measured pressure would only be from the oil pump to the valve chamber and not pressure at the bearings . The model B had a slightly different oiling system and had mild oil pressure to the main and cam bearings only .

early chev 6 had 15 lbs pressure, ford had maybe 3 lbs. So if they put a gauge on the car people would be worried because they had no oil pressure, at idle hot you have 0

I used the gauge all the time when I used to work on cars. Later cars with full pressure oil. You could tell if the mains were going bad. If you say were going 45 miles per hour and you stepped on the gas and the oil pressure dropped sure sign of loose mains.

Re: Ford Dealer & Service Field's take on Oil Gauge
 

We have always added an old pressure gauge to our cars that did not have one already.

As mentioned above, 15 lbs starting cold. 2 to 3 lbs at idle when warm. 5 to 6 lbs when driving warmed up.

At least you know your oil pump is working. Makes you feel better. Enjoy.

Re: Ford Dealer & Service Field's take on Oil Gauge
 

A gravity oiling system is a volume system, not a pressure system. The actual measured pressure is irrelevant...only volume flow is relevant. An oil pressure gauge is just an easy way of indirectly detecting oil flow.

Re: Ford Dealer & Service Field's take on Oil Gauge
 

Thats sort of what I said , while explaining how the system works . In some cases it has worked well for the past eighty some odd years .

Re: Ford Dealer & Service Field's take on Oil Gauge
 

I absolutely agree with what you said :)

Re: Ford Dealer & Service Field's take on Oil Gauge
 

What is that carburetor?? And where is that line going from the oil pump bolt?

Re: Ford Dealer & Service Field's take on Oil Gauge
 

The Zenith carb is from a Model B; the float shape says 1932. Converted many years ago by a PO.

The oil line shows the pick up point for the oil pressure gauge. An on/off valve has been installed just in case the gauge or the oil line fails (keeps oil from squirting all over).

Thanks !!! No harm meant at all . As far as I'm concerned We are in agreement.
