Take the timing cover off and you'll see where most of it came from.

Why are you taking off the heads?

Are you rebuilding it? Does it run badly?

Yes it is.

1969: Parts made of high quality materials by Americans for American cars in the US.

2016: Parts made of "whatever" by Chinese, for nothing in particular (motto: "We copy, we sell, you buy, bye bye!") in Shang Zen.

Unless you want to make specific improvements, if it ain't broke, don't fix it.
Also, remember, the original head gaskets were steel shims about 0.016" thick, while the standard replacements are fiber and steel, about 0.047" thick, so you will lose about half a point of compression if you pull the heads "just because" and then reassemble with "standard" gaskets without milling the heads.

Change the timing set. If your running, performance, and oil pressure are good, then check the usual wear items and adjustments in the distributor and carburetor, and leave the rest alone.

what he just said

this is about what your timing set used to look like

http://www.ebay.com/itm/121854159524...%3AMEBIDX%3AIT

The plastic teeth are now filling the oil pump inet screen.

Easy enough to remove the oil pan, makes front cover easier. Remove pump, get pcs out of the inlet screen. Replace timing set and oil pump, button it back up

X3--- If compression is good, valves are seating okay, and no major oil consumption, leave it alone.... Simply replace timing set....

The leaking fluid may be from your heater hoses. If you do need head gaskets there are some that are much thinner than the Felpro stuff, however they do cost quite a bit more. We'll cross that bridge later if necessary.

Octania posted a good pic of what your original timing gear should look like when you get that far. I'm sure yours will look much different once you get the cover off. You have all the help you need here to get it back running, Good advice on leaving the heads in place until further diagnosis.
I would also like to see some pics if you get a chance to fix your camera.

My timing went out last year i been rplaced that and there wer no plastic at all in that timing set....But i did read once about a plastic bushing/gasket being somewhere on the camshaft.... Or the parts The parts that move the distributor had some plastic on it....But i guess ill just have to investigate a little more.

Those look like pieces of valve guide seals. Maybe. They're a bit blurry and poorly lighted.

If it doesn't burn oil, I wouldn't even worry about it.

If the oil looks like chocolate milk when you drained it then you have a intake or head gasket leak.

Since the intake bolts are not torqued really high, stretch is not an issue.

Is there a problem procuring the proper hardware- like oh say re-using the stuff that the engine came with? Maybe getting Grade 5 or even Grade 8 bolts. Using thick Heavy Duty Washers like the factory did? Fastenal sells all manner of such things, as does McMaster-Carr....

It just occurred to me we may have jumped the gun. I missed the part where you already had dropped the pan... You might be showing us pcs of valve seals not causing worry. You are close to having the front cover off anyhow. Can you look in the bottom or thru the fuel pump hole and see if your cam sprocket has steel teeth in fine condition?

Perhaps your timing set is all steel because it has been replaced and the oil pan cleaned out already. If in the pan and pump inlet you have only a few tiny particles, that is not the majority of a timing sprocket toothed part. When they come undone, they provide a handful of material.

In taking a photo of otherwise nondescript stuff, always try to put a scale item in there, like a pen tip to point at interesting things.

Clean the oil pump screen and reinstall the old pump. Did you inspect the timing chain?

Whatever - just use some solvent. Gasoline, diesel fuel, kerosene, lacquer thinner, turpentine, acetone, xylene, trichloroethylene, carbon tetrachloride...

Don't forget to clean between the guard and screen, you may have to use a small screw driver or pick to get the plastic bits that are wedged in there,

Looks like timing gear teeth to me.

Focusing would help a lot.

The sink drain in the background is helpful for scale - I assume it's within a few inches and not several feet away.

Is your timing gear aluminum or steel?

If it's steel it's been replaced, if it's aluminum it's shot, because what you've got there used to be on the gear.

Here is a picture of a nylon covered OEM timing gear shedding.



If yours has been changed then it will most likely not have any nylon on it and the chain should not have much play.
