If you mean the rod bearings---you have to remove engine.Take off heads and split the block.Not an easy job for the amateur and you need some special tools. Piston have to come out so you might as well rering and hone.
It is not very common for Subbies to knock from the bearings,but it is not unusual for the pistons to knock.You should get the opinion of a Tech familiar with Subbies before throwing parts at it.

Best to buy a complete rebuild kit and new pistons. Very rare for this to happen...how many miles? They are called piston skirts. Could be something else though. Hard to say without tearing it down. When you get it apart, you may want to take it to a machine shop and have it bored. I've done this several times...never with a subaru....and I now just save the time and trouble and order a crate motor.

The radiator fan is probable in user-friendly terms a change or a relay - hint the wires back from the fan and you ought to be waiting to locate those. the different subject is that the vehicle is probable in "limp domicile" mode meaning the pc has detected a topic which will save the engine from working effectively. extra advantageous than in all probability this is an oxygen sensor undesirable or yet another of the sensors linked to the pc. Take the vehicle to an vehicle areas keep and ask them to confirm the pc codes for you. that should point you interior the excellent direction. If it truly is not some thing like that, then you truly've got a blown head gasket or another difficulty this is inflicting low compression interior the cylinders.

You need new big end shells. It's a major job. You have to strip down the engine, disconnect the pistons from the crankshaft and replace the shells.

It's called "engine replacement"
If it's still running pretty good and will pass smog inspection, forget about a new engine. Run it until you can afford a new CAR
