Metal debris in my engine

Never had an engine blow up or wipe a cam, so I need some ideas on how to clean up the inside of block. I bought a 5.7 with a piggy-backed rod bearing and the metal grit is everywhere (not sure if lifters would be contaminated). Everything is coming apart, so what's the best way of cleaning? What about cam bearings?

Use degreaser, hot soapy water, solvent ect to break down the oil film and use engine cleaning brushes and go thru all the oil galleries.

Cam bearings should be replaced if they are scratched up.

Not sure I got a good deal now. I'll do what you say with cleaning. What about sticking magnets on the block while
cleaning?

The best solvent for sludge is lacquer thinner! Cuts through absolutely anything instantly

Hot tank? Bueller? The time you save will be worth it.

Modern Hemi I assume, don't forget to toss the intake manifold in the trash if there's any doubt about the extend of damage and if it went through the combustion chamber. The debris is known to get into the plastic and then come back out into the new build. It's impossible to clean them.

From looking so far, basically crank journal and rod eat up, still running before getting pulled. Can feel metal partials imbedded in other rod bearings, like sandpaper. What's the filter for, chunks?

The filter is for chunks that make it into the pan and pickup tube.

The trash that killed your bottom end never made it that far.

If you can feel it the filter would have caught it.

Unless your engine has a filter without a bypass, over 80% of your oil is not being filtered.

I've come to the conclusion filters are useless on race engines then, just a restriction. Big Magnet in the pan would work better. Lol

Well, there are a lot of non-magnetic, non-ferrous metals in an engine these days.

The lifters will be contaminated too , I spun a bearing on a 383 many years ago , it had a cam and lifters I just put in a few hundred miles before the bearing spun. I opened them up and flush them with brake wash and ran the solution thru a white rag , every lifter had metal in it .

I'll have to look and see if I can pull the roller lifters apart, major bummer.

Another vote for having it tanked. It's really not that expensive to start with.

Do you mean hot tanked?

Most hot tanking is now discontinued because of pollution concerns but most machine shops have updated ways of cleaning blocks that come out very nice. They still need scrubbed at home before assembly but it a simple process after they do their thing.
