Should I be concerned about...

Should I be concerned about...
I got two questions. First off I have maybe a minute of runtime on these lifters before I had to shut it down. So the cam didnt really get a chance to break in.
I figure not many people have torn a motor down after a minute of run time to see what the lifters actually looked like, but maybe some of you could either ease my fears at least? About 3 or 4 of them had a nice circular spiral pattern going on already, 2 of them looked like this:
The second part is that this damn bolt broke while I putting the intake on.
Is it worth the risk/trouble of using an EZ-out on it? Is it worth the risk/trouble of just ignoring it?

Why did you shut it down and then tear it apart after only on minute?
Are you sure that the spiral pattern wasnt there to begin with? IS it a deep pattern, or just one that can be seen but not felt with a finger nail? The lifters are meant to spin in their bores. They designed the cam lobe at a slight taper to make the lifter spin.

2. The spiral pattern looked very faint, not worried about that. I think it just means they're spinning which as far as I know is good. I'm worried about hte ones that seem like they weren't rotating, like the one that's pictured.

Re: Should I be concerned about...
Damn, I should have posted a pic of my lifters when I removed them to re: moly lube them up.
They had a tiny circle about in the middle of it. Some had virtually no marks, very hard to see.
Just re-lube with moly lube and reassemble and keep going.

And what about the intake bolt?

Where's that bolt go? Just holds the intake to the heads right? So remove the intake and you should have some bolt material coming up. Then you can just get vice grips on it and remove it.
How did you snap that off???!?

What lifters are those too? hardfaced?

Re: Should I be concerned about...
If that is a vortec setup, IIRC the torque setting is only 15 ft/lb. If using factory style bolts with loctite on them, you will need to heat what's left of the bolt to soften the loctite. Use a left hand drill bit and extractor, and make sure no metal goes anywhere you don't want it to

Re: Should I be concerned about...
That bolt looks like it's in a prime spot to let coolant come into the lifter valley. Very annoying. BTDT.
The bottom of your lifters have a distinct bottom end part. My lifters for flat tappets have been one piece, those have a seperate part for the cam surface. Vizard refers to them as hard faced lifters. Apparently they are good. :shrug:
I'd fix that bolt though. It's a PITA to be dumping out all your oil because of water in it.

I'd be fixing the bolt too. Next time don't buy chinesium bolts..Check the bolt length. You seem to be getting all the bad luck

Re: Should I be concerned about...
I tried an EZ out. Didnt work.
The only way to get it out now is to pull the head off. And I just spent 25 hours over the last two days putting the car back together... If I have to pull it apart again, it's just going to have to wait a while to run again.
Who knows, maybe I'll give the ez out another shot tomorrow. It just doesnt look like it's going to come out right now.
And that mark on the side of hte lifter Im pretty sure is just grease/oil/lube whatever from where I was holding it.
