2.2 rocker assembly

[toyota>subaru]

I have a phase 1 2.2 and it ticks extremely loud from one of the heads (maybe both). I read up on the valve guide issues more commonly found in the phase 2 engines. It isn't a valve guide; I have checked all of them. I took the rocker assemblies off and inspected the little lifter pieces in the ends of the arms and I noticed on one assembly, all of the bottom lifters were "pushable" and the top ones were rock solid. On the other assembly they were all rock solid. I'll also mention that when driving it tends to bog down at low rpm's under load and is extremely unresponsive. Idles great though! and the ticking matches rpm.

Are they supposed to push in with finger pressure?

Is it possible to switch out my rocker assemblies with the solid lifter type from the phase 2 engine? (by just bolting them in).

you can switch to a 97/98 solid lifter set up with no issues (phase 1 as well)

Technically speaking, in order to swap from a hydraulic lifter setup to a solid lifter setup, you would need to swap the cams as well. The profile is different.

Interesting, do you know what changes would occur if i straight bolted the assembly in without changing cams?

i had no idea i though the ej22e used the same cam throughout the phase 1 life

please elaborate

are the rocker arm ratio's different?

if someone has the spec's from the 95 fsm please post them
for the 97 (first year for ej22 solid lifters)

intake valve timing
opening 4 btdc
closing 52 abdc

exhaust timing
opening 48 bbdc
closing 12atdc

couldn't find anything for valve lift, but i do have cam lobe height, but i need the normal diameter and the rocker arm ratios
lobe height
intake 32.244-32.344mm
exhaust 31.964-32.064mm


op: sorry to hijack your thread and turn it all techy

without the rocker ratios and the camshaft base circle i can't tell a thing about the actual valve lift, but there is a difference in intake valve timing between 95 & 97

The difference wouldn't be in the lift, it would be in how steep the ramp was. I'm not sure you would see it in the typical cam specs, because the difference would be in the time spent at max lift, whereas the duration specs they show are probably from when it first hits .050" lift to when it closes to .050". I'm not a machinist or an engine builder so I don't know all the specifics, but my understanding is that if the opening ramp on the cam is too aggressive, it will cause the lifter to bleed down. On a solid lifter, you don't have that issue. If you look at cam specs for older pushrod engines (where it is more common to have different lifter arrangements, like solid or hydraulic, flat tappet or roller, etc) you will see different cam profiles for each setup, like hydraulic flat tappet (like most stock setups) or hydraulic roller, etc...

Anyway, this has gotten off-topic.
