#355 of 439 XT oil pump
Apr 20, 2010 (12:32 pm)
Would the oil pump make a knocking sound on my 2004 Subaru Forester XT?
The oil light came on. I checked the dipstick - oil was full and clean. I started hearing an intermittant whirring/humming/slight squeal for about 10 miles as I tried to make it home. I didn't hear valves clicking or upper engine noise so I kept going. The engine never overheated beyond normal. Then I heard the crunching of the oil pump falling apart, and the engine stalled. It turns over but has a loud knock when it starts. I turned it off again as soon as I heard the knock. I don't want to run it long enough to hold the brake, give it gas while in 1st gear to do a poor man's load test.
Could the oil pump make this sound or do you think it slipped a rod bearing that quickly?
#356 of 439 Standard long block replace an XT?
Apr 20, 2010 (12:50 pm)
Hard to find a salvage yard XT engine for my 2004 Forester XT with automatic transmission.
Can I swap in a regular long block and use the turbo's external parts?
If so, what years would be compatible? Thanks
#357 of 439 Head gasket

The short block on my 2002 forster was replaced. Does this mean they also changed the head gasket while fixing the block? So far I have not had any issues with the gasket but I've heard stories.

Nope. Different block.
The turbos have a semi-closed deck block, plus some different internals (forged connecting rods for starters).
Parts are different.

To answer my own question -
A local mechanic told me the oil pump bolts can loosen a half turn until they hit the casing. This is enough to lose pressure from bypass leakage.
I figure I should have stopped driving right away, tho' the oil level was good on the dipstick. I think there'd be little upper engine noise (from lack of oil flow) due to the overhead cam design - no lifters clattering.
So the mechanic and I are pretty confident I've spun a rod bearing.
Anybody know where I can get a good used (low miles too) XT engine for my 2004?

There's a pretty good chance you did! Lesson learned, albeit the hard way! That's better, though, than having thrown a rod or otherwise damaging the block itself. In this situation, you could tear down the lower end and rebuild it, maybe even saving some money in the process. I agree that valve noise would be a likely indicator of low (or no) oil flow. Squealing, though, is another very good sign....

Yes, I'm concerned about the squeal. I'm hoping when I rebuild that the turbo didn't get bled dry. With so much potential of damage, I recommend Subaru install an oil pressure guage instead of an idiot light. It just made me feel like an idiot.
#362 of 439 getting a new engine
Apr 28, 2010 (6:58 am)
I need a engine for my 2001 Subaru Forester it had a 2.5 sohc vin # 6 and automatic.
What is the opinions about a rebuilt or used or a used JDM?

Both used and rebuilt can be good bets; I would go with one that comes with a warranty from the seller, as head gaskets always can be issues with these engines and you don't want to plunk one into your car just to find out a few hundred miles down the road that the gaskets are bad....

I live in Colombia S.A., and just bought a Forester S 2002, from an USA diplomatic; it has 65.600 miles on it.
The fact, itīs doing 18 MPG, i can not see the Check Engine Light in the panel when turn the key before starting. Is it possible it is disconnected now? if yes, how do i turn it on back again?
The Subaru dealer here, they told me that USA version has problems with the Oxygen sensor, instead off the Japanese ones.
What can i do with the consumption?
