Torque settings?

AFAIK the rocker covers are M6 bolts... therfore they will be 8-11Nm 
, if theyre M8 bolts they will be 19-26Nm.
Ive given you a torque window as opposed to a specific number. Sometimes, not often, but a bolt wont pull its torque. So ive given you a window to put them in.
Providing theyre in that limit they will be fine

Frayz is spot on, hope you've got a small torque wrench, the bottom bolts are inline with the chassis rails
I have known someone who done this job to just tighten the bolts up with a spanner (tight enough is good enough attitude) and ended up shearing a bolt

Thats great. Does the bolt say on it if its M6/M8?
Also, my cars a wrx 1995 import. I was told to take the battery and washer bottle out to do the gasket. How long do you think it takes to do??
Am i right in saying that all i need to do is take cover off clean up oil, change gasket and seals, seal the gasket with some sealant (RTP??), and replace cover??
Cheers.

The bolts are M6, use a 10mm 1/4" spanner to loosen off then it's easier to undo by hand due to lack of clearance, when tightening up again, do so by hand and gently nip up with a spanner to get enough clearance to use a torque wrench.
It is possible to do the job without taking the battery and washer bottle out but it's extremely fiddly, best to remove.
The gaskets are rubber, so don't need sealant, just give the heads and the rocker cover gaskets tracks a good clean.
Take your time and don't rush the job, it's easy to do but by the same token, due to space, it can be frustrating

Nice one. Just waiting for a reply from extreme scoobies for the gasket set. Don't think i can stand the stench of burning oil any longer, lol.

If there really isn't room to get a torque wrench in I don't remember the formula. But you can work out how much pull to exert on a ring spanner, using a spring scale (fishing scale) & a measured distance along it's shaft, to give a torque figure.

The principle is right but it's a bit of a Blue Peter cobbled together apparatus. 
I have an old skool "bend the bar & read the pointer" torque wrench in my tool box. Comes with a 360 degree disc to tighten to a torque figure & then so many degrees after.

Or you can always sod the formulas, and have a little bit of savy and nip them up and then turn them on a further 1/8 turn.
At the end of the day, its a rocker cover and not the main bearing bolts. Just have a bit of mechanical sense and tighten them just enough. They're not exactly under load.

Torque(Nm) = Force multiplied by Distance, force being the turning push or pull and distance is measured from the centre of the nut etc to where force is appled, jusy incase you was wondering

I know one of my old motor bike rocker covers was prone to leaking if you didn't nip it up evenly. It wasn't so much worrying about snapping a stud more about getting an even pressure over the face.
There was a rocker cover with a cork (
) gasket that had to have the nuts tightened in a specific order as well. Very ****. That's old British iron for you.
Modern gasket materials should have pretty much put an end to the days of having an oil patch on the floor. There was a bike shop in Ipswich that had a drip tray under every secondhand British bike in the showroom. Ah the good old days.
