Help! When turing the crank......
i just got done aligning the cam gear and crank gear. i noticed that when i turned the crank over by hand a heard a noise every now and then. its not a grind, and it doesnt really sound bad. is it just noisy because theres not much oil in there? it doesnt lock up or become hard to turn, it just makes like a noise like something rubbing on something lightly. i know nothing feel into the oil pan (bolts, lifters, etc) so is this normal? or am i screwed?

No you aren't screwed. You just need to find the source of the noise and correct the problem. If your engine is out of the car it should be very easy. If the engine is still in the car then the noise must be directly related to the parts you installed on the engine. If you have difficulty finding the source of the noise, start removing the parts you had just installed and and turn the engine over and see if the noise dissappeared. If it does then you know the noise was being caused by a problem with one of the parts you just removed. Check each of the parts for any sort of abrasion that might have been caused by rubbing. Also, check each piece for high spots or burrs that might have caused the noise. It will probably be something simple. Good luck.

^^it sounds like its coming from the back of the motor, like around the flywheel. im thinking because i have the oil pan dropped because i needed to get to the pickup tube bolt, that that might be causing the noise. maybe the dipstick is rubbing, or somthing back by the flywheel is rubbing. im going to put the oil pump on and tighten the oil pan back up and then see if the noise goes away.
really the only new part ive installed so far is the cam, which went it VERY easily. there was no forcing or hard pushing needed. just a little bit of turning and it slid right in.

Do you have the pushrods and rocker arms on yet? It could be as simple as the cam pushing the lifter up and then it is sliding back down onto the cam as you are rotating it causing a slight tapping noise.

I had my car sitting for a bit, and when i cranked it over doing the same thing it made noise too. I ended up adding some oil on the cylinder walls, after a few more cranks by hand the noise went away.

thanks man!
unfortunatly not. just got a new computer so all of them were lost. since that pic ive also added some black halos and clear corners.
Now its back on to performance!!!!!! (if i can ever get this damn thing done.)
Also, i got done with tightning the oil pan back up before i went to work today. and the crank is still making the noise when i turn it over. ill be doing the springs tomarrow, and hopefully have this thing ready to fire by monday night, but if that sound doesnt go away im kinda afraid of starting the car.

its a 99 camaro. yes an LS1.
if that happened how hard is that to fix? i dont see how one of the lifters could have possibly gotten messed up. i used the JPR tool to hold them up when swapping the cams, and they slid in very easily, just had to turn the cam by hand a couple times.

I think BNKBRKR had the right idea. Sounds like a lifter. When you removed your rockers, pushrods and rotated the old cam, this nested the lifters up in their retainers. This is a 97 LS1 Camaro correct? It's possible that one of the lifters up near the firewall fell back down after you got the cam installed and started turning the crank. When you rotate the crank, you hear the lifter riding up and down on the cam lobe. You are at the point where you can install the new pushrods and rockers anyway. When you put the pushrod in the hole, push down and you will feel the lifter slide out of the retainer onto the cam. If a pushrod falls to the level of the others that you pushed down and this one doesn't push down, that is the lifter in question. More times than not the lifter falls correctly on the cam. Like DaddySS said, button things up then check for noises. I would get the pushrods and rockers in so you have some tension on those lifters, then you can rotate the crank and listen for noises.
