Ok, so I bought an older 302 and it was locked up, in order to unseize it I created a concoction of ATF, pb blaster, wd40 rust removal soak, and deisel fuel, dumped it in the cylinders and let it set for a couple of days. BAM! It got the motor unlocked. Now that all that crap has been sitting in the pan the last week or so, Im getting ready to attempt to start her up. what should I do about cleaning all that crap out?
Just drain it?
Seems like all some of that could be harmful if I just drained it, changed the oil and tried to start it.
Any suggestions?

Pull the spark plugs and push it out with the starter. You do realize the rings are probably stuck, don't you.

I'm not entirely sure what all is going on under there. I've turned the motor a full rotation and its building compression. Other than that, I'm not sure what else to check :/

You softened up the rust that was in the cylinders and used the compression rings to scrape it off. You have to decide to rebuild it or try to crank it as is.

At this point Im going to try to crank it as is. I was just curious as to what precautions, if any, I should or could take when draining that combination of chemicals, short of just changing the oil.

Change the oil again after warming oil up to flush out all those solvents.

That was my plan, thanks guys

Push it out the spark plug holes with the starter and put some gas in a squirt bottle, put that in the cylinders, push that out, should clean it up pretty good. That concoction doesn't sound to combustible to me.

drain the oil, push the crap out of the cyl's with the starter/plugs removed then reinstall all and fire it up or at least try too
