Still Crank But No Start, 05 Impala 3.8. What'* Wrong?
I believe side to side play in the rockers is normal/intended. Reason your not getting play on the other 2 is because they are under tension.
Oil in the bottom corners of your lower manifold is normal also.
The last video with the oil fill port, this is a tough one. A rod knock sounds like dull heavy metal hitting dull heavy metal. You can feel it throughout the whole engine. 3800'* are notorious for having rod knock if the crankcase is filled with coolant(usually the intake gaskets cause this).
I'm wondering if you have collapsed lifters on #5. Pull the rockers off and see if you can "squish" the push rods into the lifters.
Either way, the engine doesn't sound right. Pull it, and strip it down. If your not familiar with even the BASICS of engine rebuilding or don't even own a micrometer, this project isn't for you. Find a junkyard, spend $500 and get another engine. These things are a dime a dozen anymore.

Is it too late to still reply? I've found the Problem and it'* not pretty..
Hey everyone, I know it'* been a long long time, but that'* how long it took Me to find this problem, Well I did have other projects that I was working on...
So it turned out to be the suspension I had, The Lifter, one of the #5 Lifters, Cant remember if its intake or exhaust, but it'* the 2and to last lifter going from left to right (I.e counting from cyl #1-5 in the front bank) Also the Cam lobe its riding on is chewed up too "As expected ". So that means the Cam is shot. And looks like it'* one camshaft for both banks.
I still have dreams of repairing this engine. At least at the bare minimum I'm looking at replacing all the Lifters along with a new camshaft. I want to know what'* involved?
Please dont tell Me the camshaft comes out from the transmission side...????
I know I might have to drop another engine in it, but, I want to explore My repair options 1st, if its cheaper (money wise) I'll go that route, I know it definitely won't be Cheaper Labor wise, Lol. But, I'll be doing the work at My own time and Pace. The gosl is to spend the least amount of $$$ possible.
So let Me know guys.
Chewed up Hydraulic Lifter Roller Bearing.
Same Here
Oh this is worse
The shot hole, Idk how visible it is
Ate up Cam lobe

Metal throughout the system.
If the crank is damaged in any way, complete rebuild and replace the crank. Cam shaft will need replacing along with all cam bearings. Either way, engine has to come out for rebuild.
Any way you look at it, this is a COMPLETE rebuild. Prolly have to have the pistons replaced as well.

If the engine is coming out I'm just gonna drop another engine in. Dont have time for rebuild. I heard these engines are dime a dozen cheap.
But, I wanna know how to change the Camshaft or what'* involved and Which side of the engine the camshaft comes out of... ???

Your loss if you don't inspect everything.
Cam can come out the front of the engine, but not while the engine is installed. Some people have tilted the entire engine/trans at such an angle, they were able to get the cam out over the passenger side fender. But this requires disconnecting engine mounts and passenger side dogbone mount.
Again, IMO, just pull the engine and do it right the first time.

And, just a brief reminder, as Mike mentioned earlier in this thread, the engines are a dime a dozen, especially if you broaden your search to include series 3 as well.
Unless, of course, you wanted an excuse to upgrade/modify, in which case you have it...

If that'* the case, I Might as well put a series 3 in it then... I thought they were different.... So what makes them "Series 3" then? if they're Just the same engine???
The S3 don't make any more Horsepower than the S2...... :o

If that'* the case, I Would just add another $200 to it and Buy another whole engine, I priced out 2 in My area, One 122K Miles for $450 and the other 95K Miles for $400. With 30day warranty.
But, Buying a new engine Means I'm gonna Junk the one in there now, and I wouldn't wanna do that, because I have torn the engine down to the point where I can easily replace the camshaft. But, I don't wanna spend more than $150 On the engine, I Already have a set of Lifters.. SmH
Please, Anyone know where I can get a cam for about a Buck or Less?
