Silver sludge in oil
Hello all should I be concerned with silver sludge in oil? I'm redoing some stuff to figure out what previous owner did and did not do. So far it's got viton everywhere so that's a great sign but I am seeing this silver stuff and want to make sure it's ok

Could be excess assembly lube? Was it a fresh rebuild? Might be no issue at all if that's the case.
Is it magnetic? Is it a fine powder type of material or can you feel some grit when rubbed between your fingers?

Re: Silver sludge in oil
Is it slimy? could be lead deposits from back in the days of leaded gas that never got cleaned out. If it is that not a big deal. I would guess that if it is not magnetic (not steel) and not crazy amounts it is likely of little concern. I have seen large globs of slimy silvery lead deposits in oil pans before.

I used to use silver anti seize lube on all bolts

Re: Silver sludge in oil
The motor was gone thru by previous owner and rings replaced and all that. It is slimy. Not metallic like metal but like a lubricant
Guess I shouldn't be too worried
Thanks!!

Re: Silver sludge in oil
I think that is the answer. I bought anti seize for aluminum and it is aluminum in color. Why there is so much of it I have no idea but I think that's the winning answer. Maybe from when the rocker bolts were replaced who knows.skipvair wrote:I used to use silver anti seize lube on all bolts

Re: Silver sludge in oil
Here is a photo of silver sludge in an oil pan. In this case it was around 1/2" thick and covered with oily goo. It is lead deposits in this engine. I am guessing this oil pan has not been off for a very very long time. Most of the bolts in and around the engine appear to be untouched since new:)

Re: Silver sludge in oil
Could it be zinc from the oil?
