Block cleaning
I have my block all stripped down and I was wondering if anyone had any easy way to get some paint off the block? It is paint I put on a couple of years ago but I just want to redo it since it is out and easy to get to.

Re: Block cleaning
Take it to the quarter car wash. Stop along the way and pick up some oven cleaner.
You can probably figure it out from there.
Take your gun cleaning brushes along with you, and pick up a SMALL toothbrush-shaped wire brush and some engine cleaner that's just diesel fuel in a spray can (Gunk Engine Bright, or any of the store-brand "engine degreaser) while you're at it. Run your .410 brush through the big passages that go all the way from front to rear, liberally doused with the diesel fuel; your .22 brush through the ones that go upwards from the main bearings; and use the toothbrush-like one on the groove behind where the cam bearings will go later on. Put the block out in the sun to dry; coat the cyl walls, main bearing saddles, and lifter bores with trans fluid to prevent rust.

Re: Block cleaning
Easier way, 90* die grinder, and a disc. maybe a scuffing disc would be better so you dont accidentally cut into the block. Sand her down, brake clean it and re paint, should be good enough. at least its what I did.I like the results And it was cheap too.

Re: Block cleaning
One word. Hot tank
If DIY-
Make sure and pull every oil galley plug out of the block esp in the rear before doing this dont want to have any leftover gunk get flushed through new bearings thats never fun. Some shops never even do this figuring youll never know the difference.
Make sure and take note of what you removed so when you replace them you have oil pressure when you start it lol.
Keep flushing it out over and over and over.
Takes just a tiny bit of nothing to ruin a new motor.

Re: Block cleaning
Yeah I have a hot tank I can use but it doesn't work the best. Leaks real bad and the water needs replaced.
