I found where those chunks of aluminium floating around in my engine came from! Check out this disty drive gear.... Can't imagine what would have caused it, any ideas?

 

Also, as you can see, the crankshaft bearings had seen better days....

(or not, im sure that picture wasn't that dark and crappy before..)

Does this dizzy still spin cause if the bearings in it where about to seeze they might chew it up, just a guess tho.

Thats the wierd thing - the dizzy seems fine. The gear on the end of the dizzy shaft even looks fine!

i'll bet that's the distributor gear on the cam/crankshaft. or from an old distributor. makes you glad someone decided to put a screen on the pickup tube!

Seems rather odd but.... Some things point to the culprit being the front main seal. For one thing, there are bits of churned up seal all through the sump (oil pan). On close examination of the drive gear, it does look if something has been dragged 'through' it.

So, im thinking that 'somehow' the front crank seal was pushed bachwards untill it contacted the disty drive gear. Then at some stage it got caught up and torn to pieces and deposited in the sump. (someone then replaced teh seal, and didn't wonder where the other one was???)

All seems very unlikely, but why else would it look like that, and why else would there be chunks of rubber seal in the sump?

 

Anyone think this is feasable?

I do - it seems to make sense - especially looking at the floaties you showed in a previous post
