Um What did i do??? Well i did my cam swap, and just as i went to start it, i heard a loud POP, then immediatly heard the loudest 'PING"..It was ringing my ears.There was some faint smoke.And realized that i forgot to attatch the spark plug wires to the spark plug
..So i shut it down..
I took the valve cover off and noticed that the 2nd to last rocker had no tension on the spring and it was torqued down!!!..Its not a piston, or connecting rod because the other rocker, has tension on the same cylinder..
It looks like the 7..I mean i can move the rocker up and down off/on the spring..I can't take it off, because irs torqued down
Im guessing a lifter went sideways???

lifter may be in the oilpan .. or whats left of it ... and the valve may have hit the piston ... did you get the spring locks back on ? sorry to hear this ... lots of things could have happend ... did you turn the motor over by hand before starting ?

The spring locks never came off..Yeah i turned it by hand so many times..Of course it gets difficult to turn when the rockers are on because you are building compression, other than that nothing..I mean why only that one??
trying to understand your problem here...is there a pushrod on the back of the rocker, maybe forgot to install? did you use anything to hold the lifters up while you did your cam swap???
did you not install any plug wires or just the one where you have the problem?

yeah there wa a pushrod against the lifter, rocker bolts torqued to 22ft lbs
i took off the heads first and then the lifters, then the cam..
i didnt install the wires on the driver side..forgot all of them..but i installed them on the coil packs

so if you take the rocker off the pushrod is still against the lifter then right? the lifter may just need to be pumped up with oil pressure... have you tried starting the car again?
the loud pop may have just been the engine backfiring because half of it didnt have plugs on...

but here lies the question
Why is that specific rocker not compressing the spring?

Verdad Gallardo or are you saying if you spin the motor over by hand that the rocker never pushes down on the spring? you need to spin it 2 full turns of the crank to be sure...

At least on the other ones, there is tension on the spring, so you cant move it..This one nothing as if the rocker isn't even there

Ill try turning it more than 2 times and let you know right now
Sounds like you bent a valve. Was there any coolant in the cylinder when you put it back together? I cant remember if you put heads or not. Is the tip of that valve lower than all the others? Also check the pushrod to see if it is bent.
just make sure you have someone watching or check every 1/4 turn to see if that rocker is moving... there is no reason it shouldnt move though and im guessing it just needs to be run for a couple minutes for the lifter to pump up...

No coolant in the cylinder when i assembled the heads back together..I checked the pushrods yesterday, and all are fine and straight....Ill check the valve tips right now..But when i looked yesterday, it all looked normal

Its so weird cuz all the others are fine..I hope it aint that bad.
could possibly be a bent valve too i guess... but if he turned it over by hand before he started it i would think he would have felt that. if there was coolant it wouldnt bend a valve it would most likely break a connecting rod when he fired it.
but if you did install the cam not perfectly dot to dot you could have bent a valve... you did verify dot to dot correct?

i dont think anything else could make a noise as loud as you described except for maybe a connecting rod or crank breaking.
