yesterday i was running my valves on my big block
and noticed gold dust in the oil on the head
really fine not a lot just noticed on my iron heads
had to dip my finger in the oil and look at it
what could it be(hope it is not the bearings)
and why on top

just changed from castrol 10 -30 to mobil 1 5-30
filter was clean from last oil change
oil pressure is good no funny noises
im not running a bronze gear

please help

You running bronze valve guides or guide liners?

 

[Bear]

I would be worried about bearings

x2 on the guides. I had some guides going away and noticed that in the heads.

Whats going on down in Monexico?

i dont know dont get out much
just playing with (oscar the grouch) green nova
always something

do i just need to keep an eye out.
check filter

You could pull a couple of the valve springs (with the piston at TDC) and move the valve back/forth to see if the guides are loose. Valve has to be off the seat a little though. If they are they'll probably start wiping out your valve job if left unchecked. Is your rocker geometry correct (ie in relation to the valve tip)?

Do you know Jim Vincent that was in the Army @ Ft. Leavenworth? Had a 68 Camaro (Green Hornet) with 502 ran 11's.... maybe 12 years ago.

the guids would have to be wasted and most of the material would go down not up// if the filter is clean the upper end stuff could be shim material if the shop didn't put a hardend shim under the spring will eat in to the shim most of the metal will stay up top. the dampner will saw through the shims... 2cts?/

GOLD DUST=BRONZE
Bronze Gear.?

I had gold dust in my motor for a while because of a gear fittment issue ( it was tight) now its cleared up after a few oil changes since the gear wore itself into position.,...Gold dust is definatly not bearing
(bearing would be silver guys)

 

[gimmemud]

Make sure you dont have an inner valve spring broken, look at all the valve springs and see if any show more signs of the gold dust, if so thats the bad one. Could be the spring broke and rubbing the guide. I have had this happen twice.

yenko69 i will check with the machinist before i start tearing apart

gimmemud i will check for broken spring

excellerter iam not running a bronze gear
but also thought it would have to be silver before a struck gold

thanks so much

Gold Dust

Could also be valve float and the retainer hitting the guide if you clearance was close and your springs are going away. Check your spring pressure if none of them seem to be broke.

Tell Him Scott (butler muffler) from Leavenworth said hello and hope all is well! Lost touch with him....one hell of a guy met his son once too....Nathan can't remember for sure , their stuff ran like stink back in the day but that was when 10's and 11's were FAST!! SORRY FOR THE JACK!

Doesn't Jim Vincent own the drag radial malibu that Merriman drives?
If so its an 8sec ride now, no more 10-11's.

Are you running a thrust washer behind your timing chain? Excessive wear to this could cause what youre seeing.
