Disconnect motor mounts from block, drain pan, lift by balancer a few inches to clear pan. Front & rear crank seals are tricky. This is not a job for inexperienced.
the motor will bolt up, compression ratio will change unless you get a cometic head gasket that is matching for both.
I have no clue, but it sounds tricky
To change the water pump in a 1998 Subaru Legacy Outback, start by disconnecting the negative battery terminal and draining the coolant. Remove the timing belt covers, then loosen and remove the timing belt by marking the belt's position for reinstallation. Next, unbolt the water pump from the engine block, clean the mounting surface, and install the new pump with a new gasket. Finally, reassemble everything in reverse order, refill the coolant, and check for leaks.
You may need to replace the radiator thermostat and gasket.
I just got a quote from my subaru dealer for a 2002 outback wagon with the 2.5 engine, and it's $1750. Check to make sure you aren't covered under the recall. If you aren't......I had head gasket, timing belt, and drive belts all replaced for about $1100.00 on my 02 outback wagon. At the dealership.
The new catalytic converter and gasket for my 2005 outback wagon was $830 installed at an independent Subaru specialist. Are you sure that yours is not covered under warranty (80,000 miles, I think)
head gasket blown. reface the cylinder head and replace gasket. that should fix the problem
sure
The oil pan is at the very bottom of the engine. The gasket sits between the oil pan and the bottom of the block.
You may have a blown head gasket.. Check the coolant overflow for oily, black residue.
Same problem turned out to be a hair line fracture to the head!
