89 D150 LA318 Roller TBI /a999 2wd 1/2ton

So I got my engine rebuilt and I've only put 44 miles on it so far. I changed the oil and it was dark, not pitch black but it was time. Anyways I noticed it had fine brass colored metal in the oil and cut the filter open to see the brass specs. The only thing I can think of that is brass is the bearing for the dist intermediate shaft. So I pulled the dist and shaft to take a look at the bearing. It has some wear on it for sure. I'm not sure if this is normal. Do they wear into each other and eventually stop giving off metal? Or did the machine shop mess something up? Any thoughts? Things I could check? Thanks.

Is it a new bushing and if so did you burnish the bore to the correct diameter?

That was done by the machine shop. So I'm thinking they did not do it correctly. Here is a picture of the brass bushing before I ran the engine. That's the priming rod in the hole in the picture.

No very. It drops right in with no resistance. Here is a picture of the shaft when I took it out just now.

Ate the crank bearings. Time for another full go-around.

Take the oil pan off and unbolt one of the main caps and look at the bearing. Or have your engine builder do it. Was the engine broke in properly ?

It's under warranty. I'm going to leave that to the machine shop. Yes, it was broken in properly.

HMM it ATE something and the above would be a good guess, WAY too much metal in that filter,

I ain't sayin the shavings are from the bushing but dont it look in the pic like it ain't all the way down (seated)? As said with that amount of glitter it has to come apart. Holler with any news

That is indeed an insane amount of metal in the filter - really really insane for 44 miles so what like an hour of run time????

I agree I almost have to say the worst it has to be bearing material.. I cannot see that amount of debris coming from the distributor bushing. I would drop the pan you will probably find even more and bigger chunks in the pan and pickup, and if you pull main and or rod bearings you will find damaged ones I bet...

So what would cause a main or rod bearing to fail so soon? Is it likely that it was the machine shops fault? Bear in mind, they gave me the engine back with the rocker shafts backwards and rocker arms in the wrong places. Had two freeze plugs leak badly and need to be replaced. And they didn't bother to chase any threads from what I could see.

/I'm going to call the machine shop on Monday to tell them they need to take care of this.

In the picture where looking down @ the bushing, it looks like it is worn on the face. The intermediate shafts looks shiny under gear as if the two were rubbing together. May be just the picture though.

That's not the bushing that's the bearings for sure. Don't run it no more. It has to came apart. Sorry.

Could have wiped the cam and the resulting metal shavings took out the crank bearings. As mentioned, that engine is toast and needs a full boat tear down.
