Opel Addict Since 73
Some may think I'm crazy but I'm desperate to prevent further rusting of my Manta & Ascona frame rails from the inside out. (as they're prone to do) So I devised this method that seems to work well. I drilled a small hole in the top of each frame rail in the engine compartment. Each time I change the oil...I put rubber plugs in all the other holes along the length of the frame rails...and then use a funnel to pour hot engine oil into the frame rails until they're full. When the oil cools...I pull the plugs, drain the oil and go on my merry way. When hot...the oil creeps everywhere and seems to keep rust from growing. Whether you view it as creative or eccentric...it seems to work. Anyone else try something similar???
