Even through the plastic the decks look good.

Not sure what you are going to use to compress the rings, but the tapered tube compressors work very well.

Well this sucks. I have two cam bearings not perfectly aligned with oiling holes. Its the first 2 cam bearings starting from the back side. They are not driven in far enough. is this an issue? I figured they should be pretty much in alignment with the blocks oiling holes.

 

I did not but the machine shop used glass beading process/technique on the tops and ring lands. Looks pretty good to me.

 

Now that Im thinking the oil holes have enough opening to feed the camshaft journals. Maybe I am being picky? I doubt that they need a really high level of flow.

now that I have analyzed the situation I think it’s fine. The oil holes appear to be larger than the opening in the bearing. It looks worse on picture than in person due to the angle. Unless anyone has some major objection it seems to me that these cam journals will get plenty of oil.

And a nice taper on the cylinders.

You are probably fine with the cam bearings.

 

Yeah I’m thinking there is plenty of room for oil to make it’s way in. I think they make the block piling holes larger than the bearing so there is some room for error.

just paranoid at this point. A man spends a ton of money time and effort. He certainly does not want to have his motor grenade. I think I would just push it off a cliff and have a drink.

 

I've come close. You can get them aligned front to back, if you want.

 

the first 3 are spot on, number 4 is very close, number 5 is probably 80%. I’m thinking it just needs to be pushed in deeper not much maybe 1/32”

I have some large sockets, could a man just find a close fitting one and drive it in a little bit? I’d rather not f my self over and damage the bearing though. I don’t have a bearing tool. Maybe I can rent one if it’s still bothering me.

 

I set up a tool using washers. I have a camshaft video showing it, I think it has the part numbers from McMaster.

I could ship you washers to do it, but don’t know if you want to wait that long. They may be just fine the way they are.

 

I tried to drive the first one deeper than it’s a driver tool that fit closely. Now I done f***ed up the bearing lol. I ordered a few more. There are some tools on Amazon for driving cam bearings. Maybe that is a better approach. Live n learn. I’m sure it would have been fine but it was bugging me. Time for a beer.

 

Beat it up with the wrong tool. Idiot!

I would have done the same.

Well, it sucks that you goofed up the bearing and I'm sure you're now second guessing your decision to "mess" with it. But I'll throw this one at you to "try" to help make you feel better.

Although you likely could have just left it and it "might have" been fine, my guess is that although it "might not have" caused any problems, there's a possibility it would have. And it might not have showed up in 50k or 100k miles but perhaps it would have with some issue with the cam. Or, for all you know, it wouldn't have caused an issue with the cam at all.

But, here's the thing. If you wouldn't have done anything, you would have ALWAYS been wondering if you should have while you were driving it. Especially considering that you are spending all of this time and money (probably the time being more of the important factor now but of course I could be wrong) on this project. And if something did happen, even if it wasn't directly related to that oil hole for the cam bearing journal, I'm sure you would have always "wondered" if it was related to that EVEN IF it wasn't.

So, I guess, in short, you were damned if you didn't or damned if you did do something. Either way, you can't (or couldn't) win.

Obviously none of us are there to actually see the situation in person but your pictures have good enough resolution that we should be able to see what you are referring to EVEN THOUGH you mentioned that the angle was a little different. So, based on that (and what you typed), I would say that it doesn't "appear" that the bearing was lined up properly. But, in fairness, I am not familiar with how they are supposed to sit in this particular engine or whether there is an "angle" to the way they appear as we can see them in the engine. So, maybe it was "okay" or acceptable. But of course, the holes should simply line up in "most" cases. But, maybe this is a different case. Again, I don't know and there are people here that do know these things so they can point out if the bearings should have been moved in another 1/64" or 1/32" or more or less. Or, if the holes weren't lined up properly and they should have been installed differently (turned slightly one way or the other).

Look, I'm sure you were likely doing the same thing that many people have done before when doing work of this magnitude. Whether it's an engine rebuild/overhaul or you're taking apart an alternator, steering box, transfer case, transmission, or something else fairly complex. You run into something that doesn't look right so you question it. Then, you do some research and find that you aren't getting a clear answer to your concern. So, you ponder what to do in your garage all the while wanting to move forward because you had momentum and now you're feeling that momentum slowly going away and you don't want that to happen because then it's hard to get it back (sometimes). So, you grab a cold one and think about things for a moment or two and go back to trying to do more checking or whatever work is required on that part of the project. And then it's 2 or 3 am and you know you have to get up at 6 or 7 am to do whatever so you know you need to get your butt to bed. And if you're married, the spouse is wondering what's going on not necessarily because they are upset but just out of concern since it's getting so late. And then you start to feel like the project just took a bad detour since the spouse was concerned. Or, maybe not (which is great) and you're just getting tired so you know you have to just wrap up tonight's (or the day's) work and head to bed.

And when you turn out the garage light, you feel a little defeated because there was a hiccup in the progress. At the same time, as you're getting ready for bed and in bed trying to get the 3 or 4 hours of sleep that you so desperately need, all you can think about is that damn bearing that you just now screwed up and are thinking you should've just left it alone.

Nah....no you shouldn't have. Because it would have killed you if you would have left it alone.

So, I say to try to look at this in a "positive" way even though it's going to cost you more money and time. Of course nobody wants to have to do this stuff but at least if you get it done and it's done correctly, you'll feel a lot better knowing it was done correctly while you're driving that truck down the road. It's a bummer obviously but hopefully you'll get new bearings and a tool to install them correctly and that will be that. I guess I would ask others if there is a particular tool or way to install them so that you don't damage them AND PROBABLY MOST IMPORTANT, how to properly line them up and to what depth they need to go. Is it exactly in line with the holes so the alignment is the same on both sides and the holes are lined up 100% even with the oblong shape of the hole in relation to the hole in the engine or something else? (I'm sure the answer here is obvious but perhaps there is some different way they should be lined up for this particular engine for some reason).

Hey, at least it's just a bearing or set of bearings that can be replaced and won't cost much money in the overall project. It could have been worse like messing up the engine block itself because it was dropped or damaged.
