Default Help!...Is my 05 STi Dead (Video/Audio Clip Included)?

Last night on my way home from work I began to hear a light ticking noise from the engine area of my 2005 STi, 68k miles.

I have heard this sound once before. The previous time, a few months back, the ticking noise seemed to be caused by low engine oil levels. An oil change seemed to have fixed the problem….Until now.

This time, as soon as I heard the ticking I pulled over at the nearest place I could buy oil (Walmart) and checked the oil levels. Like my previous encounter with this noise, the oil levels were low again. I added a few quarts of oil and headed home with no worsening of the noise. Fast forward to this morning, the oil levels were normal (midway between the gauge on the dipstick) so I headed out to get the rest of the supplies for a complete oil change. 2-3 miles into my drive the ticking sound began to get louder under any type of acceleration. As I stopped for a red light the car felt like it was going to die (idling low and dipping). I made it another block to the auto parts store and shut off the car. After about 10 minutes in the store, I came back outside and decided to check the oil levels again. Still normal, however, this time when I turned on the car the ticking/rattling was much louder (like an M16). I proceed to put the car in gear and limp the few miles home…I never made it. 5 seconds later the car sputtered around the corner and died. In an effort to not further worsen the problem I used AAA and got a tow back to the house. It will start but I don’t want to make things worse….

Any ideas and help will be greatly appreciated. What should I do next? Hoping for the best….

Forgive me for sounding like a NooB, but if this is the case what are the possible solutions?

Thanks Again.

Anything else it could be. I've also hear it could be Spun bearing & a bad Belt Tensioner...

Could have a cracked oil pickup.

well my motor sounds like yours, but much less faint. The bottom line is, its either a spun bearing or broken rod. In either case, its a problem internally within the block, and you best bet is to buy a new Shortblock and build it up. OR, if u low on cash, you could jsut replace the shortblock with another stock sti 2.5L shortblock ~$1800 and call it a day (not including labor)

before you take your motor out, check the belt tensioners first. My friend had a bad belt tensioner on his 03 WRX and it sounded very similar. However it was immediately following a timing belt install, and his car had like 110k on it. But you might as well check it in case.

Jeeze, I'm not sure what's worse. Timing belt problems or oil problems. Both = $$$$

What's the best way to check the belt tensioner?

Thanks Again.

Possible but not likely. Sounds like he oil starved the engine by not checking his oil levels regularly, like every time you fill up with gas.

Cracked or broken oil pickup usually equals motor all overs itself.

OP, get a new ej25 shortblock. I would drop some aftermarket pistons in it while it is out, as well as pick up a new oil pickup from this guy here(killer b). I have one, its a nice piece and a good, cheap insurance policy for your engine.

Spun a bearing.....
Could have been a lot of things that caused it, I'm sure a second of metal on metal did it in.
How long had the car been burning oil for?

spun bearing...

I'm sure the initial low oil condition (a few months ago) started the process and the recent episode was the nail in the coffin.

Here's a quick and dirty way to check: drain you oil and look for "gold glitter". Also, remove your oil filter and cut it open. It will probably be full of gold flakes. The flakes are fragments of you spun bearing(s)

A less likely scenario would be the broken oil pick-up. Did your "idiot light" for low pressure come on?

You're definitely looking at a rebuild of the bottom end. Either reuse and build up your current block w/ forged pistons, buy a preassembled built block (RAW is highly recommended), get a used stock block (risky- you don't know how it was treated), or buy a new factory shortblock.

Whatever you do, DON'T REUSE THE OIL COOLER ASSEMBLY FROM THE RUINED BLOCK! BUY A NEW ONE! Many have made this mistake only to have their new block, turbo, or cams get ruined shortly after installation due to the trapped particles meandering out and clogging oil passages. No matter how well you clean it, you're not likely to get ALL of the particles out!

Good luck!

I drained the oil and didn't notice the "gold glitter" but there was a feint metallic residue mixed with oil on the top of the oil filter when I pulled it out...Looked like black semi metallic paint. I haven't yet cut into the oil filter.

Additionally, could it have anything to do with the spark plugs/wires etc. I have yet to changed spark plugs @ 68k.

Thanks for all the responses.


P.s. Any ideas on the possibility of it being a bad belt tensioner?

When you do a bearing like this can the short block be reused or usually it's too fuc*** to be rebuild with aftermarket rods pistons etc?

Eh. You can rebuild it depending on how severe the damage was. I have spun 2 bearings both on ej20's (never will go back to that motor) and I ended up just replacing the block with a ej257 and built internals.

You can rebuild it as long as there isn't any severe scoring on the cylinder walls (although you could just bore it over) or damage to the crankshaft, or any of another million factors. I mean you could refresh everything in the motor for big bucks, but for the same price I PERSONALLY would get a new block. You have to really evaluate damage. But to say the least, just replace the block.
