After enough heat cycles you fill see these seals harden. Sometimes the oil journals clog because of poor maintenance, incorrect oil, or standard bearing wear breakdown. Mechanical items always wear overtime. Stay ahead of maintenance and prevent a spun bearing. I bought a 97ex d16y8 with 190k that spun a bearing after a month and #3 was the culprit due to this seal. I bought cheap standard bearings to do 3 rounds of plastigage to check tolerances and then ordered honda oem bearings (not cheap) based on those tolerances. After 100k miles you will likely have uneven bearing wear so don't get 10 of the same main bearings. With Honda, and others, you may have 2 different bearings (top and bottom) in order to achieve proper oil clearance... Different clearances may be desired if doing a turbo build. My rebuild required 4 different honda oem main bearings and i was at the limit for thickness because of crank wear. Not every crank should be reused if you want another 150k+ miles. Definitely replace the thrust washers while you're in here... 100% of the time. Great video and kudos for pointing out the proper materials to use.
Thanks for the video. Had no idea about the seals under the main bearing caps. I’ll be doing an engine rebuilt soon due to same issue in your video. Now I know
Search for parts diagrams to get oem part numbers or call the dealership. My local dealership guys allow me to text them pictures of my parts or diagrams for them to reference.
@@AutoMotoMechanic ive opened up two f23a and a f23a1 also a f22b1. None of these have this o ring under any of the mains. The mains are integrated to the girdle which I'm sure h22 are the same. I just acquired a h22a4 from the junkyard and I would like to know if it has one

This is the reason my F20b blew up. The o ring was rock hard. Do preventive this maintenance people!!
Almost decided to skip this in my rebuild, but you've convinced me to go ahead and replace it.

THANKS! no oilpressure problems but explains my dead center bearing cap
Have you oem part number for this.?

Where can i buy an oem replacement like the viton
are you building an h series? haha #Senditpapi!
I wish you would make more videos I’m in the process of rebuilding a F23A5
Where you find this diagram? Would like to have as reference & other sections of engine internal. Thanks in advance!
How did you know this was the problem? or how did you find out?
thank you so much for the dimensions and OEM part number! almost impossible to finde anywhere else. Do you have the engine parts number listing?
The OEM part looks to be a Square O-ring... Did it worked with the standard O-ring?
Do you also change rod bearing to ???
Mi e was same exact way. I pulled the oring and was hard as a rock.
Does anyone have a part number for the o ring
dear how can you do it when cransaft still in car
Me alone in my room at 14 1:26.
If I was to buy that seal what will I call it

HE GOT IT FROM AMAZON! 🤣🤣🤣🤣🤣
F23a and f22b1 don't have this o-ring only h22s I guess
No the F series has it for sure. I opened mine and found it under #3 main

@@cambodianboost3945 yo must not have looked. My f22b1 is open right now. And has this oring in it. You may wanna look again man.
@@cambodianboost3945 you have to knock the cap off the girdle. It's between the 2

Run berrymans b12 in the oil for 20 minutes then change oil . cleans the system out. If you still have low oil pressures you got problems lol
No silicone on orings. Use oil
