Default So my ej251 was burning oil like a pig, so i swap the engine...

So my 2002 ej251 was burning a lot of oil but seemed good on gaz. I manage to find a ej253 to replace it. But now the avls 3 rear plug and 2 fwd plug are not plug. And I personally think it drinks a lot of gaz. Can someone help me out to understand what I could do to get back on a good fuel economy route.

And is there something to do with those five plug(sensors). It feels like its under powered.

Thanks

EJ251 replaced with EJ253? What did you swap over? One is MAF where the other is MAP so you needed to keep your sensors.

I bought the engine that was already in a forester 02. But the engine has no wiring to the avls sensors.

So you bought a EJ253 that was already swapped into a 02 forester to swap into your 02 forester, is that correct?

I have already installed the engine in but I think that since the avls isn't plugged in, well the cams aren't giving there 100%. That's probably why I don't have a good power band and it is taking alot of gas. So is there a way to activate properly the hi cams?

I'm confused. I didn't think AVLS was introduced until 2005, so how would an engine from a 2002 Forester have AVLS?

During the swap I notice the engine wasn't exactly the same as mine, but i know for a fact that it did come out of the same car as mine. So I researched and found out I actually have an 06+

The "donor engine" came from a 2002 that ALREADY had a newer engine swapped in.

Yes, the posts could be written a bit better.

Hi Patrick, I still have my 98......just got it back on the road.
