Step 7: Tighten all bolts an additional 90 degrees
Step 8: Tighten all bolts an additional 90 degrees
It's a PITA but I've had no problems with it. For step 6, I used a 20-100something Craftsman torque wrench and just turned it down to where 11 would be. There is a faint click, but again, it worked on mine and it worked both times my buddy changed the Cometic on his DSM.

These are just to hold you over, I'll scan and post the images when the software finishes downloading. (woohoo, 15%!)

[t3hWIT]

I'm not going to be able to get these scanned, I have to wait for a cd from HP. If you need anything else, feel to pm me or just reply in this thread.

For example just before I decided to do this I took it to a shop to fix what Im fixing myself right now($900 dollar mistake). It is now going to cost me around $500 to replace gaskets, buy tools, etc and do it right. Sorry im still a little angry with them.

I understand that for sure. I do my brakes myself, many other things not too major (spark plugs, some mods), but I had the dealer do my head gasket since it was under warranty anyhow (gives me another year warranty for their work!).

Of course, that's the great thing about the community here on Nabisco, you can pop a question when you run into something strange. Mainly, I just don't have the time (commute 2.25 hours a day, work 9 hours, have a 2 year old and a 2 month old, and when I get home, it's MY TURN!)

Good luck on your work man. I might even have something to add one day, as I'm not a complete stranger to working on cars!

Im not sure on the name specificaly... it is the parts that hold the cam shaft in place, there are (3) of them per cam shaft a total of 6 bolts per cam shaft.... I dont know how this engine could have a rocker arm assembly since it doesnt have any rocker arms.... it must be the bearing caps. I believe they have a torque pattern as well.

[Russell Rogers]

Yeah Things seem to add up quick. See if you can't find some ARP head Studs for cheaper.

[BURTONRIDR]

I paid $30 at Autozone for ROL. Cometic is $40, which I didnt know about until I already had the ROL's compressed.

Ok dude. The "Camshaft retainer caps," only listed for the 2.5 motor, are 70-90 inch-lbs.

Sweet thanks

Now the only thing im waiting on is for the head bolt to get here, I should have them by friday, I hope I get them sooner its getting cold here. I have to ride my motorcycle when I cant drive my car.

[BURTONRIDR]

I need the torque spec for the bolt that holds the cam pulleys on and the bolt the holds the crank pulley on. Does anyone know what they are?

***Update: 97 legacy outback

Everything is put back together and its runs amazing. I only ran into one issue after I got it put back together this weekend. I forgot to plug in the water temperature sending unit, so I wasnt getting a reading on my temp gauge. After I plugged it in though everything looked good.

Here is a recap of everything that was replaced/upgraded/fixed:

1. Perrin Lightwieght pulley
2. Ground mod
3. Sti Motor mounts
4. Borla Headers
5. Custom short ram intake
6. New Crank gear
7. New idler pulley
8. New head gaskets
9. New Head bolts
10. New water pump
11. New water pump gasket
12. New front main seal
13. New oil pan gasket
14. New Timing belt
15. Fixed front O2 Sensor connection

I think thats about it.

I still need to do more work next weekend but the engine is taken care of.

After all that work I am very pleased with the results. The throttle response is amazing, it is great through the entire RPM range. I love the pull that the engine gives, its hard to be nice on the throttle now I need to be though for a few hundred miles and then change the oil again and I should be good to go

Thanks for all the help from everyone

[t3hWIT]

Thanks for the update, glad it all worked out ok.

[FrodoTBaggins]

However the reason Im changing the head gasket is because the engine over heated very bad

If the car is overheating and you recently did HG's maybe you should send the heads out to be checked. We do alot of them and we send out more than50% of them to have the cylinder deck machined and they check for leaky valve seals. You should look into that!

[BURTONRIDR]

I did a compression test on all four cylinders before I started and they held pressure fine.
