i rebuilt the ls for my wifes z 28 and i figured youd say cam bearing. those cross hatches looked pretty fresh though. the next to last cam bearing towards the back i had to polish to get the cam to fit. im glad i came across your channel. you get in depth but keep it simple
Thanks, it is amazing how little bore wear there is in these engines, no need for ridge reamers anymore LOL. I will throw cam bearings in it in the future and will retest. Thanks for watching!
I am dealing with the same problem new o ring no change. I put a gauge in the front side of block at pump has 45 to 60 lbs. I by-passed oil cooler lines put block off plate with gauge only 10 lbs. also at sending unit only 10 lbs. Thanks for this video looks like i am pulling the motor.
Yep, seems like a common issue, good thing is the lower end bearings get oil first, so as long as the engine wasn't hammered on it should be not so hard of a fix. I will be fixing this one in a future video, thanks for watching.
Orings and other oil seals should not degrade unless they are in contact with a chemical that degrades the base material, it all depends on what material the oring or seal is made of. Cam cover and barbell should not degrade in normal use, problem is the seals will conform to the sealing surface and take a set, then not recover their original shape when removed. If they are not heat resistant they can harden and crack, but it really shouldn't happen if the oring or seal material is correct for the application. Once removed they will need to be replaced. Thanks for watching!
Sorry to see this happen to you . Did the factory engineer too small an OD cam bearing for this block, or did an overheating of the engine take place ? When you rebuild this engine , I'd like you to make it a 427 cubic inch monster !
The cam bearings are different diameters depending on the position in the block, for some reason the 3rd bearing is thinner than the others. I wont even be pulling the pistons on this one, cam bearings will go in and retest, I like to experiment!
The filter prob would have worked if you would have kept the plug where you could put it back in the hole to slow it down and then pulled away. That would have been a pain lol. There is always great ideas at the time lol!!! I'm the king of Opps that didn't work lol!!!
Aw, come on! Pound bearings into it instead of putting it in the corner. You title the video it right, and use some clickbait… it could be the video that puts you on the map!

Thanks for the experience!

I've wondered if the push rods are out and while the engine is upside down, you could do new cam bearings w/o pulling the heads.
I will definitely be doing the cam bearings without pull the heads, fun part will be getting the cam out, I don't think its coming out the front.
another great video! thanks
Thanks for watching, glad you enjoyed it! 👍
I have the same oil tube and mine uses the green oring.
Yep it was correct, I have orange and black as well all the same size as the green. Can’t just go by color anymore.
Always check the oring on the barbell ams the cam retainer plate. The gaskeyt gets crusty amd will drain to pan. Low oil pressure

A spun Cam bearing. I never wouldve guessed that!
Me neither, never had that issue with a SB or BB chevy LOL
@ I know the piston rods could spin a bearing easily
4:06 Somes days you be the bug and somes days you be the windshield.
Exactly!
Dang that stinks. Would love to see you do cam bearings for a test.
I will be, just not immediately.

Dang she took damage!!! Sorry brother!!! I've heard of cam bearings walking out. I've never seen one till now.
All good, will throw cam bearings in it at some point and retest 👍
How many GEN 1 sbc you seen with a spun cam bearing?
Zero, no big blocks either!
I put a Melling Oil pump inmine and now I have 60lbs psi.
Not going to help on this one!
@@rust_hoarder_garage Yup, I see!

Next time!
@rust_hoarder_garage Yes sir!!!
That o-ring is flat!!!! Wow!!!
Flat and torn!

Nah, rather make videos of what I want to do, not what the analytics want. I don't want to be on the map lol
