my new project

[asshanson]

Rod bearings are easy and cheap enough to replace, and those look a little worse from pics compared to the mains. But as goodhart said, really hard to tell from pics. Maybe check all the mains and make sure they're good and just do the rod bearings?

That's a good idea. The rods are easy enough to replace

[golden763]

The other thing I never thought of did u take one of the upper rod bearings out? There usually the ones that take the worst beating the upper rod bearings and lower mains

[simulatedwood]

From the pictures you posted, you are still on the first layer, for most of the bearing surface on all the bearings in the picture. It safe at this point to just reuse all the bearings.

I have not. I can check the next time I'm over there

I hope so. So far quite a few people have said they are useable. So I'm either going to replace the rods and use the mains or just reuse the rods and mains for this summer then pull the engine and replace all of them next winter.

I agree with simulated. It looks like the break in coating is worn off. Not sure what you're paranoid about. Especially if you can't feel anything with your nail.

Run a good, heavy oil if you're worried.

paranoid that the will cause a problem. I just over think things. Bearings will be reused. And it will be using to a good heavy oil.

Anyone have any opinions on switching to synthetic before 1k miles? I'm thinking about switching to synthetic when I get it up and running. Is 625 miles too soon?

Valvoline VR1 non synthetic is probably your cheapest safe bet. Throw in a break in additive if you're keepin with the paranoid theme.

[4seasons69]

Thanks! I'll check that out. I ran amsoil break in oil for the first 250 miles so right now I think I'll stick with a regular conventional.

[Murlo26]

My current motor build I ran normal oil til 3k to be safe. My first motor build I switched at like 1000.

I would go longer but I have nothing to back that up. I think Gosh told Danny at DB to try using the regular stuff longer the second time around.

[4seasons69]

Hmm yeah map recommends 1500 miles. Most say at least 1k. I'll probably just find a good heavy conventional and run that until 1500 or so

That's a good read! I think I've heard about that but never actually read it. I will definitely be using one of the oils off of that chart.

Remember when I mentioned using 50 weight V-twin stopped my rod spinning issues?

I do! And that is exactly what I'm planning on using. :-)

VR1 racing 10-30 looks like a good buy.

Indeed! I will worry more about oil when we are closer to starting this thing up again

[bramagedained]

I'm still running non-synthetic VR1 20w50 in my car. All I can say is it works fine in my motor. It's relatively cheap and you can buy it pretty much anywhere.

Good to know. I will keep this in mind.

[turbotalon1g]

If you change oil enough I'd run non-synthetic.
