#Any particular reason why there's this much gap on my intake rocker arms?

Is the camshaft like... There?
um
why were they removed?
and who removed/installed them
and yeah does it have a camshaft
I mean, when I turn the engine, the rocker arm still moves and presses down on the valve
well then I guess something's there
I was replacing the whole cylinder head. When my friend took the "new" cylinder head from a junk car, he took the intake rocker arms off to get better access to the cylinder head bolts
Oh dear. That's so extremely not needed
Yep. Oh well, now to find out why this is the case lmao. Any ideas?
And I wondered why the car wouldn't start lmao
probably because the valves aren't opening at all
Does it have VVL? If so youve got the spring on the wrong way
Pretty sure it doesnt but its sorta a shit angle
It does have VVL, it's an ej253 I believe. I have two cylinder heads, when I put the rocker arm on the old cylinder head, it fits perfectly, very little play on the rocker arm. When I put it on the new one, there's just this massive gap between the rocker arm and valves.
Are both heads vvl?
Sounds like one of the engines is a non vvl 253 and the other is vvl
Or one was labelled as a 253 but is actually a 251
Inb4 someone pulled parts from a 2005
Send pics of both cylinder heads and their markings
Sorry for the delay, I went to bed lol. Here are pictures. Right is the rocker arm from the old cylinder head. Left is from the new one.
the cylinder head on the floor is the old cylinder head, the one in the car is the "new" / one from a junk car.
The junk car was a 2009 Legacy Wagon
my car is a 2008 Impreza Sport
To my eye, they're the exact same cylinder head, exact same rocker arm. I've also went ahead and fit both rocker arms on the old head and they both fit fine. However, both rocker arms seems to have a hard time fitting on the junk car's cylinder head, even the one that originally came with it. I remember though, when I saw it in the junk car, they fit perfectly fine before, it didn't have this gap. Maybe I'm just installing the arms wrong? Does the engine have to be in a specific orientation (TDC, BTC, etc) when installing rocker arms?
There should be a position where neither cylinder is in lift. You also need to make sure the springs on the rockers are disengaged, then adjust valve lash, then engage the springs again
Just wanted to update this, here's the reason why the rocker arms weren't sitting properly.
Oily cam cap is the damaged/snapped, clean cam cap came with the original cylinder head of my car lol. Bottom right of the oily one, that bar where the rocker arms sit just snapped. Unsure why, maybe that could've been the reason why the junk car was junked. Good thing I still have the original cylinder head lol
Here's that bar, closer. Not sure how it would've snapped but it did
