SOURCE: Need to replace clutch

hands down the trans...under optimal conditions I have done this repair in under an hour. If you were to remove the engine for this repair you are going to struggle aligning the input shaft from trans into new clutch plate when re-assembling. The trans is so light weight a jack is not entirely needed at all and no fluids, coolant or oil would have to be drained as well.If the exhaust Y pipe comes down without any bolt removal problems ,you are basically home free but do remeber to drive out the roll pins in the DOJ (transmission side axle joint)

SOURCE: how do i bleed my power steering rack on subaru legacy rs turbo

A power steering dosent need bleeding. If you replaced it a week ago and was fine until now then it's not an air problem. Power steering fluid is pumped through the system even when the steering is not being used. Definatly not an airlock problem. Cheer's

Your model and year has OBDII. I would not suggest shorting any wires. It will not flash codes. Most Auto parts stores will test it for free. Good luck and have a great day.

take it to a competant mechanic. If you are on here asking about an engine swap, you probably do not have the ability to perform a complete swap.

i would check the idle air control solenoid first. simply unplug it then remove the unit and inspect the air passage for any blockage and carbon buildup. Clean it if its dirty then test it out. If the IAC is good then you should look at the throttle position sensor.

I have a 92 legacy sedan with bad motor. Bought a 92 legacy wagon turbo. Do I have to change wire harness in front with computor, or can I change just computor?


hi im presuming your old car is non turbo if so you will have to change a lot of parts over to make it work, you will have to replace entire engine loom, the ecu will need changed over then the fuel pump and all of the fuel lines will need to be replaced with the bigger turbo model ones to keep up also the trans will bolt strait up but will be the major weak point so swap over if possible.

My 98 subaru legacy made a big sucking sound and ever since then the turbo hasnt worked and there is a strange rattle around the intercooler area,


TAKE LINES OF TURBO TO INSPECT THE TURBINE (FINES) ON BOTH
INTAKE AND EXHAUST ALSO LOOK FOR LOOSE LINE AT INTERCOOLER
OR DEBRIES FROM TURBINE IN THAT AREA IF SO DO NOT RUN
REPLACE TURBO --AIR FILTER---INTERCOOLER---TAKE ALL PIPPING AND CLEAN
TAKE OFF AT INTAKE OF ENGINE AND CHECK FOR METAL MAKE SURE CLEAN OF DEBRIES OR THE MOTOR WILL SUFFER DISENTEGRATION FOR SURE

sounds like a blown engine, you might be able to locate a used engine and get it installed, rebuilding that engine is going to be expensive. If you just replace the turbo, you would probably just be wasting your money since the engine was run with no oil.

Yes they will bolt in. Make sure you have the sensors matched. You might have to do some playing with the computer to make it all work properly. Good luck and have a great day.

97 legacy no boost


The second turbo simply follows the first when the system activates it by bringing it in parallel with the first. The first turbo is only designed for a 1200cc motor so it can not deliver enough compressed air at revs for a bigger motor so they arrange to bring in a second turbo of the same size when the first one runs out of puff.
The first turbo is a semi-mechanical device. The ecm raises the boost level at which it operates but it should be producing some boost regardless.
So concentrate on the first turbo.
Isolate it from the ecm control system
(There is a misleading tip on youtube involving pulling hoses but it is misguided, the comment is ignorant, and I do not recommend it)
Instead, as per the manual, on the first turbo remove the system pressure lines from exhaust and wastegate. Loop a short piece of vacuum hose from the primary turbo output to its own wastegate.
Blank off the system hoses you disconnected. Fit a boost gauge, drive it and observe the boost gauge readings (manifold pressure). If the primary turbo is OK this will make it operate at a lower boost level (5-7psi ?) than the system control (10-17psi) but it will be a purely mechanical operation which will isolate where the fault is.
If there is no boost and the pressure stays zero down then the turbo is not working. Check for the wastegate being stuck or maladjusted. If that is working then you bave a faulty turbo for whatever reason. Maybe there is a loose bolt stuck in it from the engine rebuild?

If the turbo is working OK then it points to an electrical issue with the the boost control solenoid which is inside the wing near the vacuum tank beside the battery compartment. The control voltage from the ecm usually pulses it on/off at a fast rate to give a measured control and it may be stuck. Maybe it is the ecm or maybe the valve. But before you go dig it out, first check the pressure lines such as 10 and 23 are connected or not reversed at their connectors where they go through the wing (just behind the battery)
Good luck
