Cleaning LS block after machine work......................................???????? ???
Here's my questions,
1. Hot tank, sounds great, but oil passages/mains is where the time needs to spent(brushes, front to back)
2. plunger and metal plug behind oil pump(removed), Plunger is out back($5 GM part), the metal plug is behind the pump; Both of these need to be removed......(not a question here, just getting it out there)
2a. the x3 oil plugs are also removed
3. Cam bearings, remove and replace to clean?
I can see the oil passage front to back for the lifters and follow the shop manual oil passage pic; does anyone have a better understanding or experience on what areas often are missed??
Don't want to fck this up missing a critical step in the build
Thanks

For Mine ,,,,,,I'm thinkin spraying(carb cleaner) and brushing spraying and brushing , then solvent and brushing then the do it Yourself car wash and spray the crap out of it then try and dry it there as best as I can until I get back home and blow it out really good . I would guess that high pressure spray if done thoroughly would get any remnants of grime that may be lurking in any inconspicuous places . I can also tell You this ,,,,,that My block is really clean already but You never know what could be hiding .

I use mild dish detergent and warm water in a bucket. I use nylon brushes to clean all the passages and bores. Then blow everything out with compressed air and finally give it a coat of WD40 on the iron stuff.

I removed everything but the cam bearings. The machine shop replaced those for me. I didnt clean it at all before the machine work but if I ever build another motor I will clean it internally and externally. I had my machine shop hot tank it, but I still ended it taping it up and wire wheeling the outside before applying enamel. I also cleaned it with mineral spirits and nylon brushed. Harbor frieght carries and nice little brush kit for $12. Also wiped the bores with atf after cleaning.
compressed air is your friend!

power washer
detergent
compressed air
brushes
I have all that, I am asking specifically if anyone understands the oil passage and route through the block and what passages would tend to be troublesome
Thanks

I save old, plastic shower curtains for jobs like this. Place shower curtain under the engine & stand.
I like to wet the inside, thoroughly, then spray 'er inside & out (& oil passages) with engine degreaser. Let sit in the hot sun, then brush, then powerwash, or just rinse with hose sprayer.

Treat them all as if the engine will blow if they are not clean. I would always run the brushes through every oil passage as I washed the block and flush them all out with the pressure washer. If the cam bearing are already in, it might be difficult to thoroughly clean the passages that lead to the cam tunnel and get the debris out from behind the bearing.
