is it a big job to do head gasket on a subaru 2000 awd

check your turbo
turbos tent to leak from the seals also its always good to buy an oil catch can

T3/T4 Turbo
Lubrication Kit "oil pump and lines"
Turbo Bracket
Intercooler
Intercooler Brackets
Aluminum Intercooler Piping
Silicone Couplings
T-bolt Clamps
Type RS Blow-off Valve
Stainless Steel Headers
Stainless Steel Downpipe
Rising Rate Fuel Pressure Regulator
Auto-meter Boost Gauge
Vacuum Harnesses
Cone Style Air Filter
PVC Filter

And to be able to Dyno Tune the engine for the extra boost. Nothing more then 8 PSI with out replacing the Pistons.

Might of forgot something but this are the major things needed.

Worn valves.

Yes it will work and is a common swap. You will need the computer. Good luck and have a great day.

It should be: TY754VBAAA

It is located on the passanger side of the bellhousing. If you shine a torch down the left side of the motor at the back near the firewall where the gearbox meets the motor you shouls see a white sticker with the code on it.

Hope this helps.

this could be down to one of the seals in the turbo leaking and letting oil through

Yes, there IS a known oiling problem:

Subaru TSB 02-103-07
Applicability: All Turbo Equipped Vehicles
Subject: Turbocharger Oil Supply Mesh Screen
http://store.forcedperformance.net/merchant2/graphics/subaru_oil/02-103-07.pdf

"... If clogged or restricted, it will reduce or cut off oil supply to the turbo, resulting in failure. ..."

Your turbo may be toast! ***ouch!***
I have found more info on 2004 - 2007 models, but may or may not be applicable to your 2000 Impreza. I am not familiar with the the UK model differences, but if yours has AVCS use your favorite internet search engine to search for "Subaru AVCS" or "Subaru TSB". Good luck!
