I am doing a light "rattle can rebuild" on my '74 Dodge Charger 318. I did a compression check and all cylinders are between 135 and 155 psi. It has 74,000 miles on it. So, my freeze plugs were rusted and leaking. I pulled them out today and was astonished at the rust and corrosion build up behind them. I need to flush this engine's water jackets badly. Any suggestions? Is this normal? I think the previous owner didn't put enough antifreeze in and the hi concentration of water contributed to the freeze plug rusting. I am also replacing the timing chain, oil pan gasket, etc. One other thing, there was coolant leaking into the oil. My oil looked really bad. My theory on that was hopefully, the timing cover wasn't sealed and was leaking water into the oil pan. Comments? TY.
