Wish I could help but I'm around 200+ miles away in north platte.
Engine removal is necessary and what threw me for a loop on the reassemble was the torq procedure.
Torq to certain ft lb then back off 180 degrees and then 180 degree then torq to certain torq and go 90 degrees more. Least that's how it was on my 99 2.2L.

Ok ill stop rambling. Its not to bad like i said I'd help if I could.

Its my sti that popped a headgasket. Still not sure which one ill be checking later tonight. If the engine has to be pulled I will just replace both of them. And as trey said beer will def be provided for anyone willing to lend a hand. Will be ordering the gaskets as soon as I find out which ones were used when the motor was built

my advice... pull the engine, replace both. Will save you a lot of time/hassle later when the other side goes.

Yup, thats the plan, We got the engine 80% ready to pull tonight in about 2 hours.  We are replacing both head gaskets for sure lol.

Gotta love rotated!

The following is the "laundry list" for a head gasket job at our shop.


Gasket - Cylinder Head 2
Gasket - Spark Plug 4

Gasket - Rocker Cover/Valve Cover 2
(this is the most common place for head's to leak from away from the block)

Washer/Button Rocker Cover 10
(this is the second most common place for head's to leak from, don't use the old buttons!!)

Seal Oil Pump Gasket
Oil Crank Shaft Seal 
Gasket - Water Pump
Thermostat and gasket assembly 
Gasket - Intake Manifold 2
Gasket - Exhaust manifold front 2

You will also need coolant , oil and filter . We do recommend new spark plugs at this time.

Hope this helps!

Anybody have any special tricks to getting the cam gears off? Don't really have access to my air tools at the moment so I can't try that.

I have used a rag and a GIANT pair of channel locks to hold them. But then u run the risk of marring or damaging the cam gears.
Air tools are the easiest way unfortunately.

Its not necessary to pull the engine...we have done dozens of subie headgaskets, na and turbo and have never once pulled the engine.  The dohc are actually easier to do than the sohc with the engine in the car.  just fyi

The engine was not hard to pull at all. Seemed like a much better choice than trying to do them in the car. I know I've heard of doing them in the car on foresters but most wrx and sti guys said to just pull the motor. Only thing holding me back now is getting the drivers side cam gears off.
