Exterior oil line

[Flyingpiper59]

So Forum Chums….Ford Faithful?…..or one of the modified Mag post lines….. I like the design of the latter, and it seems like it would get more oil than the Ford Faithful…thoughts?

Hi Edwin,
I like the advantage of having the entry point of the oiler as high as possible so you can get oil delivered to the front on a steep climb. Both the Texas T & a mag post oiler give you that advantage.

Make sure you have a magneto coil if you want to use the magneto post oiler. I did not and the magneto post unscrewed itself and dropped into my transmission. Sprayed oil all over the pavement.

Just thinking...
The reason for the outside oil line is to provide extra oil towards the front of the engine to accommodate Ford's splash oiling system when traveling up a steep grade.
--
While there are several outside oil line designs, it may be best to answer the question "which is best" as two separate questions. First, when viewing the engine on an incline and consider that the oil flow would be dependent on the amount of pressure (push) the pick-up system could provide & gravity (points A ,B or C). Secondly, where would the best place be to delivery the oil points (1 or 2).

Some pictures of where some kits were applied A = Ford Faithful, B = Magneto Pickup and C = High Volume. The Ford Faithful incorporates a transmission oil screen while the others could purchase one separately.

There isn't much of a grade before the inside oil feed pipe is at horizontal.
To overcome gravity the question is higher better (B & C) or the volume of oil available to deliver being further back & lower (A). Then which system would provide more "push" to get oil up the tube.
Then the point of delivery would be best the higher and further forward the connection. Point 2 vs 1

The Texas T oiler will provide more oil than needed. I found it necessary to reduce the flow of my Texas T oiler to prevent excess oiling at idle. It's probably the most difficult to install, but it really does the job.

The tiny hole in the mag post oiler will feed the least

The Ford Faithful will feed many many times the volume of the mag post oiler and will feed oil to the front of the engine up to the point where low band will cease to propel you any longer...see the "right side" video of oil collected on a filter similar to Ford Faithful here: https://www.youtube.com/watch?v=dXimnKoDPSI&t=78s

The Texas T oiler will send a similar or increased volume as Ford Faithful, but with a slight increase in induced oil pressure, but requires butchering the hog's head. Additionally, more oil is not always better oil. With the hog's-head grafted oiler, it may well (and often does) send so much oil to the front that the rings cannot deal with the extra volume...remember there are only compression rings on a typical "T" piston...no oil control rings.

I have Ford Faithful/Sure-feed oilers on all 5 of my T's.

Apparently there may be other factors influencing the performance of these out-side oil line kits. Oil slingers appear to have a greater effect than magneto magnets when used with the Texas T high volume kit or a Magneto post kit. But its doubtful if slingers or magnets would have any effect on transmission cover solutions.

And as pointed out - too much of a good thing is not always good.

how did you reduce the flow?

I installed a 90 degree flair appliance gas valve @ the pan. Its adjustable to regulate the flow. About the middle between off & on.

[TXGOAT2]

I cut out a section of the copper line on my oiler and replaced it with a section of hose. To reduce the flow, I forced a short length of smaller hose inside the hose to serve as a metering orifice. It reduced the inside diameter of the hose from about 1/2" to about 3/16 ". It stopped all smoking at idle and the engine has run thousands of miles since with no problems. Oil leakage was reduced, also. This car has aluminum pistions and modern type rings. I know from experience with other engines that even new pistons and rings in newly bored cylinders will allow oil burning if too much oil is flooding them. Tha same is true of valve guides in OHV engines.

The mag post oiler going to the front main puts out more oil than you think. Install one and unhook the oil line at the front main, pull down the engine speed and see how much oil is coming out. You might be in for a surprise. Of course the other larger oil line oilers will supply more oil but don’t count the mag post oiler out.

[Craig Leach]

The last engine I put together I made a mag post oiler for it ( It is not running a mag because the mag coil looked like someone had actually removed the starter with out taking the Bendix off! I will bet there where hammers & pry bars used) So I was able to make it larger than the ones we can
purchase from the suppliers and it doesn't have the contact to obstruct the oil flow. I put the lower fitting in the pan with a spout to get the oil over the inspection cover horse shoe into the dips. I put a nylon reinforced high temp clear hose from the mag post to the pan. I discovered some things
I didn't know about the oil flow in a model T. When the engine is cold you don't get much flow. Compared to when the engine is @ operating temp. The difference in flow with the oil level @ the lower petcock is much less than if the oil level is at the upper petcock. And much greater if you add an other quart. Please don't elaborate on running extra oil I was just experimenting for the sake of information while I was breaking in the engine on the run stand.

Ford said to put a gallon of oil in a new engine. Ts don't like thick oil, especially when cold. For cars in service, Ford recommended keeping the oil level halfway between the upper and lower cocks, and NEVER lower than the lower cock.

[John kuehn]

That’s a good point to remember especially if you have a stock engine. When you do an oil change add enough oil till it just starts to run out the top petcock. That’s what I did until I removed the transmission cover and fixed the leaks! Now it’s 4 quarts and just below the top petcock.
It may be a temptation to “fill it up good” when thinking it has a splash oil system and no oil pump when in reality the splash system does really work.

[TXGOAT2]

One thing to consider with the Ford system is that when the car is headed up a steep slope, the oil level in the sump area will likely increase due to oil running back to the sump faster. More oil in the sump would mimic having a higher oil level in the engine and tend to offset the effects of having to push the oil uphill to the front of the engine by tending to keep the flywheel well supplied with oil to fling. I'd still want to keep the oil level toward the upper limit in hilly country. I believe some type of auxilliary oiler is a good thing to have, if only to prevent damage in the event the standard oil line became restricted. I also believe that oiling would be improved in cold start situations, too, with more rapid and plentiful oil delivery to the troughs and timing gears, and thus to the entire engine.
