25 PSI is really, really horrible. Your problems go beyond most possible solutions. When an engine stops, one or more of the valves is open. That means that the cylinder is exposed to the air and will rust no matter what over time. Car sits for a long time. Car gets fired and run. Engine destroys its rings after a few miles as they are dragged across the rust and scale in one or more cylinders, and the engine is toast. No lubricant on the planet will compensate for rings on scale. You must do a ring and valve job at the minimum is my opinion. You're in there anyway, so might as well do everything else now and be done. Do the trans while you have it out too? Such is old-car life. -Kenyon --- o g <miami_62_imperial@xxxxxxxxx> wrote: > i have a 62 imperial the car wasn't turn on for 25 > years .i tested the compression piston 1 gave 105psi > /piston 3 gave 25 psi /piston 5 gave 40 and so on > not one got above 120 .i think its piston rings are > stuck .i let transmission fluid sit in the over the > pistons for a week .should try another fluid .i > really don't want to rebuilt the engine ..please > help me with any ideas > > --------------------------------- > Get the free Yahoo! toolbar and rest assured with > the added security of spyware protection. ____________________________________________________________________________________ Got a little couch potato?
