more oil pressure
 

Hello,

Is there any way to modify a model A ford oil pump to get a little more PSI? I have a gauge and I know the oil is pumping, but I would like have a reading so I can prevent future problems. My gauge goes to 15PSI. Any suggestions?

As always, thanks for the help.

The stock Model A he's very little restriction in the system. As Marty mentioned you don't want to or need to increase the pressure or lack of. You are probably better off without a gauge on a stock Model A...

How can it be I am just became a regular member but almost 100??

A's Always

OH, on oil pressure, it's sorta' like measuring something that AIN'T THERE, like, how TALL wuz thet GHOST, that SKEERED you????

You can plumb it for full pressure and then the gauge will mean something. :cool::cool:

Re: more oil pressure
 

You just need a lower pressure gauge, like 5 or 10 at the most. Then you can see the needle move more.

Just use REALLY thick oil - bad for your engine, but the gauge will work better :D

Plug the oil outlet in the valve chamber. Then drill a small hole in the plug. You won't get enough oil to the engine, but you will get some pressure on your gauge! JB

One thing I like about this site is I always get my questions answered and in a nice way. Sometimes I hesitate to post something on the count of looking stupid, but no one has ever made me feel that way. You don't learn unless you ask and read. I am always looking for ways to increase my knowledge so I can pass it on to someone else. Thanks everyone. Keep posting, I am reading every post.

What is thick oil? 5-20? 30 or 40wt?
Which weight is best?

Re: more oil pressure
 

You could open the inlet (to the pump) and outlets a little if it would make you feel better? Not needed and probably won't show on the ga. The stock system has worked since 1927.

Marty,there is a trick I've seen rebuilders do that involves drilling and tapping the center oil gallery and piping in a small copper line . Exactly what's going on there I don't know. Whether the gain is in pressure or volume , I can't say. Precisely how it's done I can't say either! But it has been done with some kind of success.

Don't really use really thick oil.

Be careful who you listen to about oil - most don't get it. Read up for yoursslf, and pull your own conclusions.

Allanw: Thank you for posting those links. It has been very eye-opening and extremely educational.

Thanks!

Re: more oil pressure
 

I had the same problem with my oil gauge reading low. I put in a oil pump rebuild kit from Burt's which had a modified smaller main shaft and my oil pressure reading increased from 1 psi to 4 psi on a warm engine.The guys on the forum are correct you don't need the gauge but now at least I have some reading on the gauge.

Re: more oil pressure
 

I read the post about thick oil as a joke.

Re: more oil pressure
 

I also take the comment about plugging the outlet to increase pressure as a joke!!

Re: more oil pressure
 

DON'T WURRY about low pressure, jist remember that the oil is GUSHING through the engine like KRAZY, NOT jist OOOOOOZING!!!

Re: more oil pressure
 

On a Model a engine, the oil pressure gauge reads the resistance of flow between the gauge port and the discharge pipe in the valve chamber. The higher the flow rate (RPM) and the higher the viscosity the higher the gauge will read. The pressure to the bearings will be the same, a gravity pressure of about 6" of head or about .2 psi. 100 psi on the gauge will not give you another ounce of pressure to the bearings, the gauge is just letting you know that the oil pump is still working. The model B is different critter all together.
