Knock Knock
Knock knock,
Who's there? Metal shavings! Metal shavings who? Metal shavings in the oil filter!.........  They are ferrous and the filter is loaded with them!.......  I finally got the car in the garage and opened the filter. Now the motor is coming out again for another complete tear down....... I will definitely post some pic's when I get into it. I can't wait to see what went wrong...... this time...........  Don't know what happened, installed a rebuilt turbo and the motor started smoking like a battleship at 3K on the tach running up a small hill. Immediately turned for home and developed a loud knock. I Have the motor out of the car and will start the tear down tomorrow.

I bet you didn't plan to pull an engine today.

Probably just bearing base material. I'm glad you caught it in time.

Hope against hope
Well I'm hoping that I did catch it in time. If my cyl head is undamaged then I have enough parts to build another motor. I have a parts motor without a head. I' get it to the machine shop and get going on it if the head looks alright.
And no I did not plan on pulling an engine today! It would be fun to just blow the thing up but I need the car. If it fails after this rebuild........it's time for some fun with it!    BADA.......BOOOOOOOM!!!!!!!!!!! EddiE Last edited by FLYWULF; 08-04-2009 at 03:55 AM. Reason: spelling

Knock, Knock, Okay I'll bite who's there?
Any chance of shavings from the new turbo you changed out. I would expect perhaps the bearings might have become too sloppy on the new one from your description.Or if a used one was installed they may have been rusted letting one of the bearings just fall apart basically. The rust would grind the bearing up in short order. Oil flow would then occur as the shaft seal could no longer hold to account for your smoke screen and perhaps shaving particles off the turbo blades or housing landing up in the filter.
Critically examine those particles you found. Even if you have to use a low power microscope thats if they are not obviously bearing material. The next thought was you might have destroyed a piston. Yet if a rod bearing normally you would not develop excess smoke simultainiously. Would a semi loose rotor in the turbo make a knocking noise? Possible something simular in my opinion . That filter sees the output of the turbo out oil line before the engine does. .This would protect the rest of the engine. I would check inside that turbo carefully before stripping down the engine. Or engineer some sort of easy test. Otherwise how does one account for the sudden smoking as well? ? I guess it could also be a terribly damaged piston. Your symptoms then might be identical to your description. Please allow I learn something new ever day from our site. Certainly do not know it all either. Just what I might tend to examine just as a precaution first. I usually leave no stone unturned before going inside an engine. Plus since it is usually better to locate the actual difficulty before engine removal.I usually spend some time there. I find it much harder sometimes to establish the difficulty with an engine apart. With your symptoms I just cannot see it being rod bearing material though. That excess smoking thing at the same time again. Some are much more experienced and brighter than myself. I also have some difficulty expressing myself with the written word. So just some random thoughts. . Last edited by barry123400; 08-04-2009 at 12:32 PM.

It's really hard for me to interpret thos pictures. I see chunks of metal but they don't look like pieces of bearing. They look too thick.

Too large to be from the turbo as well. Can you get better pictures or are they obviously mixed metals like a bearing surface? Pictures of what was present in the filter as well if possible.
