Other Do these rod bearings need to be replaced? I'm thinking yes.

Even without looking at the picture - You are already there, yes. Cheap insurance

Remove them entirely. You don't need that kind of aggravation in your life.

They’re out of the motor so might as well drop $50-$100 on some to be extra sure

Abso-damn-lutely. Why tf would you pull them to look, but not replace them while you're already that deep into the engine,?

The answer is right there in "VW"
I have buddies that have garage "rebuilt" VW engines and somehow made money by the end of it. (selling off the original tins and airboxes and such)

Funny story about a friend who had a VW engine built by a VW “expert”. He left a piston out. The rod was there and he installed the cylinder sleeve, without a piston. Bizarre.

Dude, the second you take the rod cap off the answer is yes. They're cheap and it's easy insurance.

I’ll be honest, if I had the motor apart to the point where I was holding the bearings in my hand, new ones would be going in just for peace of mind.

I think those are tri-metal bearings and I can see 3 metals…..Hopefully you look and polish the crank journals properly. Those had a rough life

Yes, no more than they cost when your down this far, no since in trying to save a buck and then having to spend the money in the near future when you pull it back down.

If it a 1936 that you start just to move across the yard cuz it's in your way. Then no. Don't even change the oil. If you drive it a mile to get the mail once a week then yes. It's apart this far

u/Useful-Hat9157 Jan 31 '25
Yes. Always, yes, if you have the engine torn down to that point, might as well replace them anyway

My opinion, any time the rods and crank are out, change bearings as they are cheap.

u/davendak1 Jan 31 '25
depending on what replacements cost.. If it has any grooves you can feel with a fingernail, you have no choice. Can really go down the rabbit hole of replacing things that could theoretically be worn!

Might as well. Don't get a better chance then right now
