Get rid of it. T belt and accessory change is 100K or 8 years IIRC. You can get a quality kit with tensioner for @$150. O.

I don't see any. Both are dbw, the ecs is on the front of the crossover pipe in both cases, just double check the crank and cam sprockets. O.

There may be a vin stamped on the passenger side of the block. It is on a flat surface above the axle. Will have to clean first. O.

Make sure your harness connector is fully engaged. Here is link to fsm. Look at engine electrical. http://jdmfsm.info/Auto/Japan/Subaru/ Also starting at page 171 of the DTC section is troubleshooting for the injectors O.

Make sure the crank gears are the same and that crank and cam sensors are plugged in O.

Just back off the adjusting screw so that the drum slides on. Rotate. If it rotates freely, tighten the adjusting screw until it starts to drag, then back off a little. A new hardware kit will make life easier, but not necessary.. A regular pair of pliers to hold the cup against the spring as you rotate for the clip will work. O.

The Brighton was a drum vehicle. Used a lot as a fleet vehicle. Look for exhaust leaks before the first cat,. Is a possible cause. for 420. Clear codes and swap wires to 3 and 4 and see if codes follow.. O.

Check for exhaust leaks before the first O2 sensor. What brand of O2 sensor did you buy? Reliable brands include Bosch, NGK and Denso. O.

You can pull the balancer and timing cover to inspect the belt for embedded metal and put back. If you find defects in the belt, plan on replacing as soon as feasible. O.

You seem to have two concurrent but different issues. The O2 sensor in the rear may need to be replaced, but first go through the diagnostic listed in the FSM . http://jdmfsm.info/Auto/Japan/Subaru/ You will need to remove the end covers and blow the main cover out thoroughly with air. There are still pieces floating around from the crank pulley. O.

Oops missed the hissing sound. Got tunnel vision there. O.

Irrelevant on history of 08 since it has a hole in block. Just follow what has already been noted in your other thread. O.

Either will work, O.

Yes you can. Swap heads, Intake manifold, crank sprocket, and the crossover pipe as the harness connect for the ECT is in the front and won't reach that on the earlier block as that ect is in the rear. Of course you have to swap the flywheel and timing belt guide over. Take your time and use the HG designed for the turbo engine. O.
