Just curious what all you guys do to keep internal engine clean during assembly

[RobinLBuddi]

Just kinda curious what you guys do to ensure that the cylinder walls, lifter bores, and oil galleys etc. are all clean of any misc debris.
I have the engine on an engine stand, the pistons and rods are installed, and the heads bolted on. The crank was just polished, and the cam bearings were installed at the local machine shop. But after getting it back home, it seems that every time I turn around there is misc crap on the cyl walls, and in the lifter bores.
So I just thought I'd ask you guys what kind of things you all do for this. Please let me know.

Thanks a million!!!

I make sure there is oil everywhere on the inside of the engine so it catches any debris that may fall into it.. Then I lay a big trash bag on top of the lifter galley and I also wrap the engine in a big trash bag and tie the end closed. Sometimes I use 2 big lawn and leaf trash bags. I have never found a way to completely keep the engine 100% clean over several days but the above methods works the best.
The best way to keep it clean on the inside is to assemble it 100% in an afternoon from intake to oilpan.

The Rest Of Their Shop Is Only 97% As Clean

A local engine shop mists the walls & floor with an anti-static solution before unwrapping & laying parts out on the assembly table in the separately enclosed assembly room. (Mellamine walls, Diamond Epoxy floor, 3000W Halogen full-spectrum lighting)

In addition to several industrial 4'x4' HEPA filtration systems in the shop, there is a continuous suction (1-way/out only) filtration system in the assembly room.

They've combined lots of various techniques commonly used in the best paint shops, engine & trans shops, computer/chip factories, surgical operating rooms...they just keep on fine-tuning their shop!

WOW! Now that is interesting stuff, I was gonna say overkill, but I don't think you can ever be too clean, so I'll just say extreme measures, ...always considered a good thing in this area though.

I just put a light mist of WD-40 on the cyl walls and lifter bores to prevent any rust, but I too, always keep it wrapped in a big trash bag whenever I'm not out there tinkering with it.

Thanks guys!

btw, I have tried the WD40 method and the cylinders still rusted I have heard many people use it and they didn't seem to have problems but now I use motor oil.. Maybe it was the length of time that it was on also, I dunno...

I could use a shop and a filtration system like that! That may keep my GN cleaner during storage!!

I wonder how clean the old plant was that built them in the first place?

Before assembly, clean the block meticulously three, four times with soapy water, use a toilet bowl brush for the cylinders, be sure to get oil galleys and lifter bores with bore brushes, rinse thoroghly then spray with WD-40 while still wet. (W-ater D-ispersement, formula forty). By doing this surface rust doesn't ever have a chance here. Then blow everything out with filtered compressed air especially the oil galleys, and spray with WD-40 again. Then with lint free rags that are a light color, and use ATF and wipe down the cylinders bores until no dark crap appears on the rag. Probably be lot's O' wipin here. Do it till it's clean. Spray it all down again, get the oil gallies good, Give em a shot of air in there to make sure that stuff gets everywhere. Double bag it, tape it up and call it good., But you problably knew this . Hope this helps.

Hey Two Lane, What is that solution you are talking about?
