1974 Eldorado not sleeping in barn anymore.

[bassa99]

Just brought home Eldo from long time buddy that has had bike in his family since new. Bike sat for about ten years without being ridden. He put it in service and rode it about 5000 miles since
1991.
It is on lift and I dropped oil pan and found what appears to be small rubber bits what could this be? Also the oil has very small specs of chrome with some collected against oil screen.
I know I will have to replace cylinders, should the lower end be torn down or can I some how rinse out this area?
Plan to remove heads next week to see how bad bores are.
TIA

You will need to take it completely down. The rocker pins will need to be checked as well as the bottom end.

Rubber bits part of timing chain adjuster?

 :1: on the top end.  What part of the country?  Flecks of chrome indicate the liner is falling apart.

Rubber bits come from the timing chain tensioner. Chrome flakes mean the cylinder liners are shot, and since the chips floated through the oil lines, all the crank bearings are probably scored and therefore must be replaced.  Enjoy the process!

Better tear it down or it will be "sleeping with the fishes".

Some nitwit has used silicone seal somewhere on the engine.

that's what I found to be in my 850.  Once they start to wear down, they go quick
