Unhappy hmmm, changed valve cover gasket, hit a 'bump' and now car sputters to death...HELP!

Neede to change the valve cover gasket, so I got the kit and started to take off the cover. The cover is on the side of the engine for subaru's. This fact doesn't matter but helps you visualize it.

As I started to take off the cover two of the three screws that holds it on broke. YES! annoying, they broke inside of the pieces that hold the rocker arms in place.

So i had to unbolt that part of the car to take off the rocker arms and get to the pieces that the valve cover screws bolt into. Got it?

So i drilled out the old screws without messing up the threads (hey I've got dentist hands and mad skillz) and got new bolts -->problem solved.

I put everything back together, placed new gasket and screwed it all back together. The car starts wonderfully but then chokes and sputters like it's starved for oxygen. I can give it gas which helps for 5 seconds but then it just sputters again and dies. What could I have done wrong? Does taking off the rocker arms disturb the timing or mess up the valve positions? I was ever so careful so I wouldn't screw up the valves, but maybe this is the problem? Any suggestions?

Maybe you disconnected a vacuum hose somewhere. With that disconnected then the car wont idle correctly and die. A vacuum hose is just a black hose that probably plugged into the intake an the top of the valvecover

Specifically, check the larger vacuum hoses that attach to the intake tract.

There's a huge vacuum hose on the valve cover itself, I know I forgot to hook mine back up until I was cleaning up my tools and noticed it off.

Did you bolt the rocker assembly back on in the proper order? That'd be my guess. Maybe the assembly isn't down far enough and the lifters aren't pushing the valve open all the way on that side.

You might have messed up your MAF

When you took the rocker assembly off, did you rotate the crank until the pressure was relieved on all the rockers? If you didn't, I could see how the valve springs pushing back on the assembly would make you think that it was torqued down correctly, when it was in fact, not tightened down enough. But I imagine you'd hear some slapping/knocking in there. I'd say check the vacuum line, if thats ok, open it back up, make sure everything is tight and try again. I doubt you'll snap another set of bolts, because these new ones haven't seen any heat or anything, so they should still be plenty strong.

someone beat me too it. It is almost surely a vacuum line that wasn't reattached well and is leaking, got ruined (cut, torn, worn) while you worked on the car, or maybe just popped off all together...

edit - just saw the above post. looks like the vacuum hose theory was correct...
