Unidentified Metal Objects

[Evilimports]

So when i was tearing down my engine i found quite a few metal pieces in the oil pan. I thought once i had the engine disassembled it would be obvious where they came from but i could not find anything.

The one on the very top looks like part of a piston ring. How the heck did all of that get into your oil pan did you blow the motor?

The engine still ran ok. It burnt oil like there was no tomorrow and had an extreme loss of compression.

a broken piston ring will do that...the small pieces under it look like a bottom of a piston

All that suff is too small to have anything to do with a piston land or rings. That pice that is broken up what is it made of? Looks like brass. Have you tried to reassemble it to see what it looks like put together? that round dick like pice looks sheard off. The 3/4 cresent shape part looks like a snap ring.

Strange that you motor was running when you found these things. In the pan.

Blow a T25 recently?


Pssst....those are all turbo parts.

Ding ding ding, that has to be what it is. My turbo was totally shot. Thats the only thing i didn't take apart too. I'll get it apart monday and post some pics of what i found.

Please explain to me how you blow a turbo and get the parts in the oil pan,not trying to be a dick but i just cant picture it

Via the oil return line.

Well basically when a turbo blows, shards of metal can go from the turbine wheel and exit through the outlet through the lower intercooler piping. Then it travels through the intercooler, into the upper intercooler piping and into the intake manifold. Then from there, you can imagine how it reaches the engine and ends up on the bottom of the oil pan. Usually happens when a person keeps running the car constantly for a long period of time (days or weeks), even after the turbo is blown.

Via the oil return line.

Option 2.

If Option 1 were correct then:

• All that metal would have to travel UP through your side mount intercooler instead of just laying in the bottom. Those are some pretty heafty chunks.
• You compressor wheel would be toast.
• You'd have to have a huge hole in the backplate behind the compressor.
• The metal would have to either sneak through a valve guide into the head, or around a piston and past the rings.

I dunno, you decide...

Well heres the short version of the death of my dsm. Car ran great, side swiped a curve at 70mph, got the car fixed and didn't really have as much power. Turbo started sounding weird, started burning oil like crazy and sound got worse. I never really drove it after that but i did take it out occasionally. It all makes sense, the turbo was the first thing i took off so i forgot about it and didnt consider it when i saw the metal chunks. The oil return line for the turbo is more than big enough for all those chunks to travel through.
