The second one is the one I have, and it is fantastic. I've fixed 2 EJ22 Head Gaskets and Done numerous other large repairs with this manual... It is like my bible (no offense to Religion intended)!

Yeah, it's entirely possible, you need to;
- drain the coolant,
- remove radiator fan assembly,
- take the timing belt off (I suggest removing the radiator altogether, unless you want a million papercuts on your hands if you slip and hit the rad, or to avoid putting a shifter through the core itself!)
- Remove exhaust extractors
- Remove Intake manifold
- take off all the fiddly bits (spark plugs, fuel lines, injectors etc.)
- Undo head bolts (6(?) from memory), and VOILA!

Obviously, If you aren't mechanically minded, don't follow ^ this list due to lack of detail! Depending on your motor, you may need inverted star sockets to remove the head bolts (not terribly cheap, but available from most parts stores) and you will definately need a torque wrench/torque ratchet, as you will need to bet the right tension on the head bolts to avoid fooking the head gasket and ultimately needing a new one..

It does get a bit fiddly at points, but don't lose hope, it can all be done. Especially if I can do it with my pudgy fingers!!

there's a torrent of the official subaru manual but it's not as descriptive as haynes and gregorys I think.
Why don't you check your local town library? Most of the time they carry them. Just photocopy the pages you need so you dont get the pages grubby!

Also pipsta88, did you get the heads shaved when you did those head gaskets? And have you done any eJ20T motors? My bro's 98 WRX has a blown head gasket I wouldn't mind bringing it back to life if it's worth it. What do you think? How much do you think it cost you all up? As there's an Ej22 lower Ks for $550 near by I was thinking to buy that and drop it in instead of redoing the EJ22 in my liberty.

Hey mate, nah I didn't bother shaving the heads on the 22, as it is in my daily drive, and Higher comp = higher likelyhood of failure. Just a simple fix and back on the road the next day kinda job.

I have done numerous Turbo EJ series donks when I was a mechanic, so I'm no stranger to them, the only thing is the price of repair. An average mechanic will charge through the roof, for some unknown reason, but the reality is, that these motors are no different in difficulty than any other motor, they just take a little more time. To be honest, if you have the ability, you can fix a gasket for no more than $200 (incl fluids and parts) and 8 hours (if you take your time to make sure everything is just right).

In short, if you have the knowhow and tools, fix the gasket yourself. If not, you're better off with a new motor than you are taking it to a mechanic to get it fixed.

Thanks for the info, I'll go to town on my EJ22 next week. Would it be easier to do it by taking the engine out? Or should I leave it in? I don't have an engine crane, so I'd have to buy a cheap one I guess...

Nah, it's easier to leave it in mate. Just a little bit of a hassle getting a couple of bolts out, but it is still a lot easier than having to eff around taking the whole motor out. Just make it easier on yourself by taking out the radiator, gives you a couple of extra inches to maneuver around.

Nah, the bolts have to come out to remove the head so you can fit the gasket. It's not an easy job for a beginner, but if you need torque specs for the head bolts, and all that, i have them here.

If you mean the rockers and all of that, no you won't have to do any of that. the rocker assemply and rocker covers do not have to come off of the head when you remove it. the head bolts are all located so you can remove the head and rocker assembly as a whole, so it is easier to change the head gasket.

1) Tighten all bolts to 29 N-m (3.0 kgf-m, 22 ft-lbs) in alphabetical sequence.
2) Then tighten all bolts to 69 N.m (7.0 kgf-m, 51 ft-lbs) in alphabetical sequence.
3) Back off all bolts by 180" first; back them off by 180" again.
4) Tighten the bolts (a) and (b) to 34 N-m (3.5kgf-m, 25 ft-lb).
5) Tighten the bolts (c), (d), (e) and (f) to 15 N.m (1.5 kgf-m, 11 ft-lb).
6) Tighten all bolts by 80 to 90" in alphabetical sequence.
CAUTION: Do not tighten the bolts more than 90".
7) Further tighten all bolts by 80 to 90" in alphabetical sequence.


CAUTION: Ensure the total "re-tightening angle" [in the former two steps], do not exceed 180".

Can someone help i need someone to convert this..

I'm going to need a torque wrench for this job, which one would be better from supercheap, the 1/4" drive http://www.supercheapauto.com.au/online … escription or the 3/8" inch drive? Or recommend a drive please!
Also what size star socket do I need? Are they different between EJ22's and EJ20's? As I want to do an EJ22 first, then I have an EJ20 to do.
Thanks

the 3/8 drive would be the best, quite simply because it is longer and you can get more force onto it to make it easier on yourself, and save you busting your pooper valve when you are straining away with the 1/4 drive. Personally I would recommend a Blue-point 1/2 drive torque wrench, but they are in the region of $400ea, so a bit more for a professional mechanic who uses it daily, a cheap one shoul do you fine for these jobs.

With the star socket, I can't remember and I can't check right now because I drove my GTi to work today... so when I finish this arvo I'll let you know.

Crazyrob, as promised, Torque help;

This diagram is for the Passenger side, same for driver's side, imagine you were looking at it from the "top" of the head, with the rocker cover still attached. The red "O"s are the bolts, the letters are the same as the letters in the description you had earlier. basically use the order of the steps you had before, and coincide them with the labelled bolts in this diagram/crappy picture:

http://www.ozliberty.com/home/components/com_agora/img/members/15424/Head-bolt-pattern-EJ22-lols.png

C,A,F are the top row of bolts (in that order)
E,B,D are the bottom row (in that order)
Does this make sense?

And, yes, it looks like something my 1 year old would draw, but I suck at MS Paint with a mouse. lol.

Pipsta, did you bother doing the headbolts when you did your head gaskets?
I'm trying to decide on buying a kit including the bolts, or one with just all the gaskets and seals from ebay.com (U.S)
