Default Re: Flushing engine block

Along with the long screw driver, I've used a long piece of copper grounding wire and chucked in a drill. I've also used one of shop vac reducers with some clear hose to vacuum the crud as I scrapped. This worked really well.

Overall, my block was hot tanked twice and baked once after I scraped and prodded for a few hours.
