Help, metal in oil

[383_GrandPrix]

Yeah, I sat at the kitchen table with an electronic scale and weighed every piston and rod. None of them weighed what was written on the spec sheet, and each one weighed something different so I sent the whole assembly out to the machine shop to be balanced and washed.

The block was hot tanked and magna-fluxed at the same shop. I washed it again before I assembled everything but I just washed it with a bucket of warm soapy water, a brush and a hose; I didn't get into the oil galley at all. I'm pretty sure that was my big mistake.

I went with the Lucas ZDDP because it was the only break in oil I could find locally.

Next go around, get a hold of those block cleaning brushes you can chuck in a drill. Go through the oil passages and then flush with warm soapy water, dry with compressed air and let it air dry in a warm place over night, or for a day. Then have another go.

I heard from my machine shop that the Eagle cranks typically need work even in kit form that are supposed to be ready for assembly.
Your kit did come with a balancer and flexplate correct?

 

[383_GrandPrix]

Yes it's an externally balanced 383 stroker kit so it came with a weighted flex plate and balancer.

did you use any assembly lube when you put the engine together

 

[383_GrandPrix]

I bought a bottle of Jegs assembly lube when I bought the rotating assembly and used it liberally on everything.

 

[pontiacgp]

have you looked at the crank and bearings with a magnifying glass?

with a roller cam you don't have to worry about ZDDP or breaking in the cam and lifters

 

[383_GrandPrix]

I looked at the bearings with a magnifying glass, but not the crank. The shiny parts are just polished and not gouge marks, but all the dots are pieces of metal. The number 2 bearing had one gouge mark on it.

 

[Texas82GP]

Yeah it looks like contamination to me. Buy this set of brushes and blow out every passage and orifice with compressed air.
