- Todays Ford Model A question of the day came from Wade!
He wants to know what a Babbitted engine is, @ModelA explains what it is to be an engine that has Babbitt and Insert Bearings and the difference.
He also asked if a person can add a modern oil filter to a Model A and was it started with Ford?
Paul has answers!
Hope you’re having a lovely week!
Hi Friends! More great information! It always fascinates me when I see pictures in the old manuals showing how to scrape babbitt bearings to "adjust" them! We have definitely come a long way with the superior insert bearings! They still have to be adjusted occasionally, but you don't have to use a scraper to do it these days!
One thing with inserts, they have a layer of babbitt on them. Babbitt vs Insert is like the oil argument. I have heard that if you run inserts you should have a full flow crank, same if you run a filter. Not sure if either is true.
Just as well that Model A people convert to bearing inserts anyway. My information is that babbitt bearing replacement/pouring is done less and less and is becoming a lost art for Model As. Thanks for a great channel.
Thanks, this was helpful
good explanation! thanks
Hi Tina
I agree with Paul. I have had two babbitt motors fail on me. Luckily, they were not on any of the long trips We have taken.
I did have my insert Bearing motor fail because I did not tighten the oil filter down and the oil was pumped out and the motor froze, UGG.!
I pulled the motor and replaced the mains. They sorta welded to the crank. The crack was replaced. I also replace the rod Insert Bearing as long as I had it apart. This motor was the one I have in the car driving the Lincoln Highway .
See ya down a country road, Steve
Oh wow!!! That’s a good share! I miss you guys!
The same goes. Your always welcome😀
Great information
Great Q&A
Two good question, two good answers. Thank you both for doing this. God Bless, have a great week ~ Chuck
Thank you, have a blessed day!
Well that was educational, didn't know the specifics about babbitt's. Thanks
Awesome!
Great video. Next question. Are the Cam bearings babbit or insert?
Neither, it’s a sleeve fit.
Thanks and have a great day!
When you say Babbit!
He says Rabbit!
Don't walk away Run!
Its like a loaded Gun!
Here comes the Clatter!
Of Babbit going Splatter!
I know, Grr! Bad words from the mouth....
Do Model A's have a PCV system or just vented to the outside air?
I remember old cars that I work on that only had what they called road draft tubes. VW Bugs vented to the air filter housing and used an oil bath air filter. This can make a big difference in oil change intervals, oil filter or not.
Blow-by, as it is often called, is the result of combustion material from the combustion chamber blowing past the piston rings and into the crankcase. If not ventilated, these blow-by gases inevitably condense and combine with the oil vapor in the crankcase, forming oil sludge or causing the oil to become diluted with unburned fuel. Excessive crankcase pressure can lead to engine oil leaks past the crankshaft seals and other engine seals and gaskets. Therefore, it becomes imperative that a (PCV) positive crankcase ventilation system be used.
Thanks for the video, Mike
When the PCV system was first used, many people thought of it as unnecessary. They could not be further from the truth. You hit the nail on the head! Evacuating fumes (oil, gas, water, combustion byproducts) from the engine is quite important. 😊
Model As are just vented to air.
@@ModelA Ah, sir Shinn! Did model T give you the rhyme of the day? Hmm...
Sounds normal for the time. As a former EA California Smog Technician am sure they will one day make it a mandatory modification for them 🤣or tell you they are for show and museums only.@@ModelA
How hard is it to replace the Babbitt with shell bearings?
Do you know of an oil filter that'll take reverse flow? The one I have that's 50+ years old is a strange reverse flow.
As long as it’s not Lorena we’re good 😂🤣
Omg 🤣

If you want your question answered here on my channel, you can ask here in the comments, on either one of our Facebook pages, or either of our instagram accounts 😁 It just takes a little more time.
without an oil filter, how long between oil changes would you recommend?
Hi, the owners manual says every 500 miles.
If the engine has been rebuilt "recently", you can probably go 1000 miles safely. If it's an old rebuild, 500 miles. An oil change usually costs under $25 if you do it yourself. Cheap insurance.
@@ModelARickLasCruces 1960s rebuild (maybe). I'll keep changing every 400-500 miles.
I changed the oil when it looked dirty. Then the rear seal started leaking and got increasingly worse to the point that I was adding so much oil every few hours of running that the oil never got dirty.
The engine is out now and I’m replacing the babbit bearings with inserts. Also adding a partial- flow oil filter.
