I've got a 2000 OBW with the notorious 2.5L SOC. Can anyone help me with the torque specs for my cylinder head bolts. I'm replacing the head gaskets, timing belt, tensioner, and water pump (along with misc oil seals).

 

Oooor a source for a factory service manual or regular repair manual. In all my searching I can't find one.

 

Thanks

Sorry, I can't help you with the head bolt specs. But I'm curious, did your 2000 OBW have an internal or external head gasket failure?

I understand that the Subaru website has an option where you can access factory service manuals for a fee. Make sure you're on a computer with a wide pipe so you can DOWNLOAD what you need.

it is a Subaru sponsored site for repair by outside mechanics.

Here is a link to the site:

From the wife's description it sounds like an external leak, but I haven't checked it out yet. Happened on my wife's way to work, when stopped she noticed the smoke and when she got to work and opened the hood there was white smoke. It's been smelling like maple syrup/coolant for awhile now. I'll investigate the leak tonight. With 120k, other HG threads, and the smell I'll be looking around Cyl#4 for coolant dripping on the exhaust.

 

Thanks for the FSM link...looks like I'll be subscribing.

Your welcome for the link. It does sound like a external leak that may not be hard to find.

dont know if they have any chiltons or haynes for newer subies but if they do i found all the tourqe specs for my impreza in the chiltons manual

The conclusion! Spent a day and a half for the disassembly, slowly taking pictures. (I plan on doing a write up with pics) Parts showed up 3pm on day number 3 (new years eve dammit) I did watch the ball drop with the head gaskets on but only up to the first round of torque (had to wait for the big t-wrench) and the water pump went on. Saturday the engine took shape again, timing belt, intake manifold. Final assmebly with exhaust and bits and acc. belts sunday monring. Then the fun began....I cranked and cranked NO START. After removing and reinstalling the timing belt 5 times for no reason the injectors finally primed or fuel finally got to them the car coughed and started roughly. Need to reset the ecm and check codes.

 

I did drive it to work this morning so it's running! It's on a default map because I have no temp reading. It hesitates off idle but once past 2k rpm it's strong. Will work on that this afternoon. Other than the long headbolts having only a mm or two of clearance the job was easy, just a lot to take off and on!

Oh yeah....external leak at the back of the driver side cyl head. (#4 cyl?). The well of the motor mount had a lot of caked on oil and coolant. There was also a very slight internal leak because the back driver side spark plug (#4?) had a little extra white burned on it. When I drove it to my inlaws garage the car was a good smoke machine at stop lights. Coolant dripping onto the exhaust.

Subaru has an additive for the external leaks, IIRC

U just saved a bunch of money doin it urself, and it's great to know there's in car clearence to change head gaskets, at least on the 2.5.

I need to start my write up before I forget all the details. It wasn't easy getting the cylinder heads in and out but if you tilt and angle it just right the lower rear most head bolt has about 2mm of clearance and just enough to get it back on without touching the new gasket. It takes a little while to slowly possition it but I was able to do it by myself...some hands below would have helped a ton.

One more thing, I couldn't convince myself to add the coolant addative. I couldn't get a good answer on what exactly this stuff does! The guy behind the parts counter told me to by it, but then called it liquid head gasket and couldn't tell me what it would do to the coolant other than what stop-leak would do. So I passed...he was also, IMO, talking down to me so I was glad I used 1stsubaruparts.com to get most of my parts.
