2003 Forester 2.5 SOCH Engine - What Years


Recommended Posts

Larry,

 

Here's what you need to know:

As posted in a recent thread:

 

These are the 5 things that absolutely MUST match up. You can use any year from 2000-2004 2.5 SOHC North American engine as long as these things match the original engine (don't even think JDM-the "plumbing" is all different):

 

Left cam sprocket

Crank sprocket

EGR? (or not)

breather tube on block (there are 3 styles)

oil pump for automatic or manual

 

You can swap stuff from the original engine long block to make it match.

What difference does it make if the motor came out of an auto or a manual with the oil pump?

The engine doesn't have anything to do with the tranny, besides of course, bolting up with flexplate or clutch.

 

The oil pumps are different. There is an extra bracket on the manual oil pump which helps the timing belt keep from rotating backward and therefore, jumping time.

Right, but that doesn't mean you can't swap engines around. That bracket has nothing to do with normal every day driving. Normally, your engine doesn't turn backwards.

It was there for shipping. When the cars are on the truck the manuals are left in gear. As the truck moves the cars rock back and forth slightly, this will cause the engine to rotate forwards and backwards as well, it was causing them to jump timing before they even made it to the dealer. The earlier engines in manual Legacys actually didn't have that.

The automatic is left in park, so obviously no connection to the engine, they didn't need that bracket.

 

So after the car leaves the truck, that part is useless. It doesn't matter if you put an auto engine in a manual car at all.

How many times have you seen someone park their car, leave it in gear, take their foot off the clutch and it will roll slightly? All the time, that's how many!

That bracket is there to help keep the timing belt from "jumping" for people who aren't careful.

Sure, you can use the same oil pump, and in an automatic, it makes no difference, but for a manual, it does.

 

BTW, early Legacys weren't interferential, so it didn't matter back then. Are you being argumentative for the fun of it, or are you just uninformed?
