Default valve cover bolts torque specs

anyone know what the proper torque specifications are for the valve cover bolts on my 2001 2.5RS?

the documentation in my alldata account says 24ft/lbs. but I'm pretty sure that's wrong, cause I've broken one off in the engine.

Quote:
After inspection, install the related parts in the reverse order of removal. Tightening torque: 32 Nm (3.3 kgf-m, 24 ft. lbs.)
On a side note, what's the best way to extract broken bolts?

24 ft/lbs is WAY wrong. All valve cover bolts need to do is put enough pressure on the valve cover gasket to maintain a good seal.
Typically, that's around 8-10 ft/lbs. I don't have a manual handy, so I can't tell you what the exact torque spec is for the RS, but I'd be willing to bet it's close to that range.

As for extracting broken bolts... what exactly did you break?

the center bolt that secures the valve cover. broke off about three threads in. I tried finding a piece of it that I could grab with some needlenose pliers, but no luck. I don't have a way of lifting the engine out out of the bay, so I'm not really able to get an extractor bit in their either...

okay. so I think I found a way to extract the broken off bolt. I'm going to drill a hole and use an extractor. woohoo. I have a number of regular drill bits, all of which would regularly drill through metal, but should I start with a reverse bit instead? Not sure where I'd find a reverse drill bit...regular hardware store?

Also, to be able to do this drilling, I need to be able to pitch the engine towards the drivers side, in effect, lifting up the passenger side of the engine. I tried a couple of different ways of doing it today, but am not sure how to release the engine mounts from the cross member. Do I just release the bolt that goes through the cross member @ the mount?

I may need to tap the holes once this is out. After a good look, and watching pieces of inner thread metal come out of the threaded holes, what should I be looking for or be doing? I heard someone mention helicoil? There doesn't appear to be much material there to drill out and insert something like that...

Its not cross threaded, just the bolt head stripped off right? In that case you dont need to re-tap or heliacoil it. To undo the mounts, take off the nut underneath the crossmember. Also unbolt the pitch stop mount (arm looking black thing above the tranny where it bolts to the motor) so that it can twist with more ease.

i was told that the bolts have stoppers on them so there is no need for torquing so you can torque it to the German spec

right, so I've resorted to taking apart most of my engine to get at this piece head-on. the bolt is broken off in the camshaft cap, and to get a good straight drill on it I'm just going to pull everything up till it. If successfull, I'll know most of what I need to know to install a set of cams.

I'm also replacing the timing and acc/alt belts while I'm in there.

Anything I should be looking for or doing while in there that is advisable? Checking valves for anything? I'm not sure how to check valve clearances, but since i'm taking the valve rockers off and then putting them back on, I suppose I should be checking the clearances once I'm almost done. How do I do that? Any tricks/tips?

I think the Subaru boxer motors found in RS's and WRX's use shims to adjust valve clearances, rather than adjustment screws. You're probably better off leaving it to a professional.

I've done valve adjustments, but only on motors with screw type adjusters. No idea how to work with shims.

the alldata diy docs for valve adjustment don't say anything about shims. just adusting and tightening screws/nuts on the valve rockers.

im pretty sure that if its a DOHC motor youll have shim under or over system and for SOHC youll have a screw and locknut (im a motorcycle tech so dont take my word for it)

the screw and locknut is obviously the easiest and for the Shims, if there shim OVER subie might make specialty tool for getting it out and if its shim UNDER you have to take the cams out to get to them
