Yeah come to find out the Chevy small block had an issue with the gasket being really thin in that area according to the mechanic. Since the second one crapped out again and I did not want to deal with the car again, I simply sold it as is. Could have been a different gasket material compared to the original that came with the car.

Yup. You can use the whole can. With the engine running, I suck it in through the brake booster hose. Do it SLOWLY, if you try to do it to fast you'll hear the engine bog down and you don't want it to hydro lock. I put the hose by the can opening and tilt the can slowly letting the hose suck a little at a time. Once the can is empty, shut the engine off for about 10 minutes and then start it up. You should see smoke coming out the exhaust. How much will depend on how dirty thing were.

Myth #12 - Adding a quart of ATF the day before an oil change will clean your engine. ATF added to the motor oil will clean the engine due to the high levels of detergent in ATF.
Fact: ATF does not contain detergent chemistry. ATF does contain dispersants, which have properties similar to detergents. But ATF is not formulated to withstand the combustion environment inside the engine. Havoline recommends that you keep the fluids where they belong: motor oil in the crankcase, and automatic transmission fluid in the transmission.

What I've read over the years is at the end of the can you dump it in fast to kill the engine. But it may be best if you do it, to just dump it in slow. Then go an turn the car off.
