Any suggestions? came from rear of engine.

[DeBiT]

G'day guys,
First time caller, long time listener..
I'm currently completely refreshing my 80 series, 1FZ-FE, and found this at the back of the motor, more specifically, between the flexplate, and rear of motor..
I have checked the flexplate, no visible damage, and checked the starter motor, again, no visible damage, so I am curious as to what it might be..
There is a bit that has what appears to be teeth on it, so something is missing something. That, or possibly ancient history?
Still tho, I am wanting to find out some ideas as to what it might be from, just in case I am missing something.
Long story short,l cruiser white smopked me and about 10 other people at a set of lights, ran rough as guts, and then died when I was picking up a digger for the weekend.
Motor and trans is out, everything is getting checked and fixed.

Cheers for any input.

Only moving parts back there are the starter and flywheel on an automatic. Maybe an old starter ground its teeth off and it was replaced?

My uneducated opinion is that parts of it look like eather some type of bering cage or the metal spring/cage/retainer that is inside a seal. I am not explaining it well. But most oil seals that go around say a axle in the birfield or a crank seal have some type of steel spring that squeezes them tight with the proper tension. If you remove them wrong (destroy them) like i have done you will see this. Maybe a seal blew apart or one was removed in the past and those parts were left behind.

is the top piece near your middle finger a roler bearing?

You said near the flex plate? If it is transmission parts i have no advice. I dont know s*** about auto transmissions.

One other question. Was the white smoke from the tail pipe or from under the truck? That might really help you zero in on trans or motor. I cant explain it but i have sean transmission problems cause a vehicle to stall and people think it is a motor problem.

Maybe you could start by pulling the plugs and inspect them. If they all look normal see if the motor roles over smoothly. Then maybe do a leakdown since you cant do a compression check with it out.

But if the rear main seal is intact and you found that near the flex plate i dont see what else it could be from the motor. I have not looked at the parts that join the rear of the crankshaft to the transmision in a auto. I only know what a manual looks like. Some splined shafts have little teath. I would mostly look in the area of the bell housing.

Now if that area had been worked on in the past somone couls have left something in there. Like a part of a broken seal, bushing or bearing and it finaly got stirred up.

Starter parts isnt a bad idea.

thanks for writing all this, got me thinking, could it be part of the rear main seal? I haven't pulled one of those before, so don't know what they are made from. I got a full rebuild kit on its way already, might as well whilst the engine is in a million pieces.
one thing to point out, is i dunno if those pieces of metals are new or old.. they were just in there. I don't think any of the pieces are roller bearing, honestly, some of it looks like a split pin. i checked those pieces- all are magnetic, so no alloys or similar.
when i saw those pieces, i immediately looked over the flexplate (driveplate), the trans bell housing, starter motor, and over anything i could see on the back of the motor. nothing else was visible in regards to damage, missing stuff, or anything like that.
the smoke dumped from the tailpipe, and dropping the sump gave me near 2 litres of water before the oil even started flowing. so my guess is head gasket. that, and the rusty coloured top on number 1 piston.

I think i am just going to put it down to a sloppy previous owner/s. the amount of dodgy i have come across with this truck, it seems a likely scenario.

Hoping that everything arrives by the weekend. Got everything pulled apart, so just waiting on putting new stuff back into it.
Heck, i am even going all out and ordered a swivel hub kit. its pretty messy there too lol.

Starter motor checks out okay. Throws out when told to, and no damage to gear.

Thanks for your suggestions.

Whater in the oil pan? Not many things can cause that. Sounds like you know the motor isnt right.

I still dont know about the stuff you found. So you might have two issues. Maybe a head gasket went and something still went south from the crank seal area or inside the bell housing. Maybe a cylinder hydrolocked and presure broke something in the torque converter of pressure blow something oit the rear main? Lots of maybes and over my head. But good luck.

lots of maybes ain't a bad thing- gives more ideas on places to look.
In my spare moments i will rip off the t/c and check its innards a much as i can. same goes for the spline it mounts over. no harm in checking.
whilst i am at it, i may as well chuck in another transmission filter. draining that should give me some clues if there are any problems lurking in there.

Cheers for ideas!
