stumped in the middle of my EJ22 swap...

[tricked919]

picked up my 22 today to start resealing and prepping for my swap on Thursday. I'm really only noticing 3 major concerns.

 

1.) the EJ22 Throttle Body has only 2 vac lines coming off of it going to the BPT. The EJ25 coming out has 3 vac lines coming off the throttle body - 2 lines to the BPT and 1 line going under the left intake runners to a sensor (not on the 22) and then on to a sensor or solenid on the passenger fender. The way I se it, there's going to be a vac line somewhere not getting hooked up :-\

 

2.) My EJ22 motor did not come with the lower AC compressor bracket. The EJ25 bracket I have allows me to use the 4 horizontal studs, but the short vertical stud doesn't line up with the hole on the block. Am I OK just using the 4 main sideways studs that go thru the compressor?

 

3.) The timing belt cover bolts were rusted CRAZY bad. BAd design in having the nut formed into the plastic. I broke about 4 of them. I doubt I'll be able to reuse the timing belt cover and I have no clue where I'll find one. This is bad - right?

 

That's all I have for now Thanks in advance

Plenty of people run these with no timing covers. I agree it's not a good idea to have a metal sleeve molded into the plastic, but the other option is to have the screw go directly into the plastic, and that would get stripped the first time someone removed the cover.

If you want to keep the covers, a coupe large Zip ties should do the trick to keep them in place. Otherwise, ditch them and ride on.

 

The missing vacuum hose on your EJ22 I believe is for the evap purge control solenoid which should be under the passenger intake runners. There is a steel line under the intake that the evap solenoid hooks to. Then a hose from the evap solenoid to the top of the intake manifold

 

The MAP sensor and switching solenoid vacuum comes from a line from the back side of the rear intake runner on the passenger side. It goes to a T, from the T one hose goes to the fuel pressure regulator. The other hose goes to the Map sensor on the strut tower. You should be able to just take the hose that's in your car and hook it up on the 22.

 

Here are some pics for reference. Took these with my camera phone so the quality is not the best.

 

This is the T for the FPR and MAP sensor vacuum hoses.

 

This is the vacuum hose routing diagram for the EJ22. Not very legible... I'll try to get a better pic tomorrow in the daylight.

The two rear cover peices run about $30 to $35 each from the dealer. Most dealer's stock them since they break so frequently. I've bought a number of sets. If it were me I would replace them.

Fairtax... the problem is that my EJ22 only has 2 lines going straight to the BPT. There is no brass noodle coming out for the 3rd one that goes to the purge. Even your diagram shows 3 lines coming off the throttle body - confusing me more :-\

[Fairtax4me]

Just T it off one of the ones that goes to the BPT. Or T it off the one on the passenger intake runner. Or get a huge T, and T it off the brake booster line. Doesn't matter as long as it gets vacuum from somewhere.

 

The nipple on mine isn't on the throttle body it's actually on the manifold. Just sticks straight up.

i run tons of Subaru's without timing covers, i say don't worry about it. my current daily driver has been naked for a few years, not much to worry about. particularly considering you have a non-interference engine and completely ebay timing kits are only $80 for all new belts, tensioner, pulleys. i got 40,000 on mine like that so i'm do for another kit next year at about 60,000.

 

they're not hard to install after the fact, so move on ahead and do that later if you want.

 

yes i've left out the a/c bolts before, there's way too many anyhow in my opinion!

 

i already replied about your vacuum concerns on the other thread.

 

how about that, 3 concerns and 3 easy answers.
