Found in oil pan....Any guesses?

[Kim]

Thank you in advance.

Valve stem retainers?

 

[Kim]

I was just thinking...valve keepers....same thing?

 

[broncodriver99]

Yes looks like valve keepers.

 

[Broncobowsher]

Not valve keepers, no groove inside. Maybe the top of a lifter?
Any chance of getting something to reference a size? Can't tell how big they are.

 

[Eoth]

I was thinking lifter also,,,,

 

[Revelation]

Bushing for the dist. shaft?

Only other pic at the moment.

I was thinking along those lines

Looks like parts of the valve stem casting from the head. Check under your valve stem seals. Sometimes when bronze guides get installed the bored out casting at the top is very thin and cracks off. Just my guess.

Part of the wrist pin or lifter? It looks more like lifter to me. Hard to tell the size tho.

I think Bax is right. It looks like cast iron from the original cast in valve guide. When bored out to install a repair guide that leaves the guide standing up from the spring seat very thin. They usually break off when installing the repair guide. The pieces would be about 1/16 of an inch thick. Repair guides can be either cast, or bronze. Knowing what engine is and the type of material might help.

Sorry...you're working with someone that has zero engine knowledge.

I assume this engine is a 289 or 302? What year? My guess is early, pre 1969 with adjustable rockers. Can you measure the ID, OD and length of those pieces? If they were pieces of valve retainers, witch I don't think they are, they would be hardened steel and would be tapered.

 

[blubuckaroo]

Valve lash cap?

 

[Scott C.]

The later 302's had a hardened steel cup that went on top of the valve stems, between the valve stem and rocker. But, it does not look like that it what it is.

302
1973
Sorry, can't measure. Don't have the pieces here.

 

[bmc69]

I'm going with Bax's guess...looks like pieces of the guide castings.

Something important?

 

[Kim]

Was this in a running engine? Did something happen that made you take the pan off or were just doing some maintenance and discovered the pieces?

Running engine. Pan was removed for maintenance.
