The difference between Babbitt and Insert Bearings & modern oil filters | Ford Model Q&A 

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....

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!

Great video. Next question. Are the Cam bearings babbit or insert?

As long as it’s not Lorena we’re good 😂🤣

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.

How hard is it to replace the Babbitt with shell bearings?

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.

Where do I send my questions?

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

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.

Thanks, this was helpful

Great information

good explanation! thanks

Well that was educational, didn't know the specifics about babbitt's. Thanks

Great Q&A

Two good question, two good answers. Thank you both for doing this. God Bless, have a great week ~ Chuck

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

without an oil filter, how long between oil changes would you recommend?
