Default 99 2.5 rs is this the end?

Hey guys I was driving my 99 2.5 rs home when I noticed a rattling sound coming from the engine. When I got home it was getting louder and louder so I shut the car off and checked the oil and it was bone dry and I still had about 1000 miles to go before a oil change. Which is strange because she never leaked oil, or over heated ever! So I filled her back up with oil hoping it would be fine but that didnt fix it. She makes this rattling slapping sound now and white smoke is coming out the exhaust. :-( please help

sounds like a rod bearing failed, probably from oil starvation, and then lack of oil also caused overheating which popped a headgasket or two. Probably most economical to drop in a used engine but a rebuild/overhaul would get you another 100k+ miles if you can deveop a habit to check the oil regularly. i try to do it every fill up. I keep a few shop rags in my trunk in a zip lock so i can wipe the dipstick after im done fueling up. boxer engines, especially the n/a ej engines, tend to consume oil.

It will vary, and you usually get what you pay for. If you paid someone to pull it, disassemble, replace all the wear parts and gaskets/seals, do the timing belt and all associated bearings/pulleys (which should be done every 80-100k miles), install and test its going to cost several thousand. I would guess a dealer would charge at least $4k. They might charge $1500 plus the cost of a used mid mileage engine ($800-1000) to swap yours out and used one in. I'm just guessing at labor costs and estimating parts costs.

So my block is complete junk now and can't be rebuilt? I wouldn't mind having it rebuilt so that way I can swap it into my vw vanagon syncro later down the line and do a sti swap in the RS

If I went with pulling another engine I could use one from a 98-01 Forrester or legacy 2.5?

Needs to match in terms of SOHC vs DOHC for wiring purposes, but that's it.

If I go with a 99 jdm 2.5 I would have to switch over the harness as well?

Unless you did some damage to the structure of the case it something, it can be rebuilt. Even then, you can always get the part to fix it. Just might be more $ than another engine.

Depends on the year and engine model, SOHC/DOHC like was mentioned. Some years of the JDM had a different EFI system a year or two before the USDM, so the harness is different and the hardware/software that controls the sensors is different. Many of the sensors are probably different, too. If you can get the ecu & harness with the engine that would probably be best no matter what. The tune will be correct.

If you want rebuilt, check out CCR in Colorado (Denver suburb). I'm guessing ~$3500 shipped for essentially a "0 time engine". Almost everything is new & updated.
I have one of their engines in my Legacy.

You may be able to rebuild yours, hard to say. But it will take work.

If you just buy a used WRX engine, you may be buying someone elses issue. Then there a lot of other things you need to do.

If you can do your own work, fine. If not, it can get expensive.

Your car, your choice.

I believe the 02 2.5 had a MAP sensor and the 99 2.5 had MAF If I'm correct

Auto to manual makes no difference just swap the flywheel.

I believe that is correct. However it wont matter if you're just swapping the short blocks. In that case, you would swap over your current heads, intake manifold (with harness and sensors), and probably the timing components to the new block. Heads might not be necessary, you would have to research that part.

Yes! I was getting frustrated when I saw them bring that up. Just buy any sohc ej25 and swap your intake manifold and wiring onto it. It will work just fine. You don't have to worry about it being the same year or any of that garbage.
