Gas will generally not go bad after sitting for several months...if it's over a year...than I would be carfull. Inspect the tank for any of this sludge. To be safe pump out the tank of the old fuel and put in some injector cleaner into the system with fresh gas. Make sure you put the right amount of injector cleaner in with the amount of gas...if you don't mix it the way the manufacture suggests than you can damage some fuel components (anything rubber, etc..) When gas goes bad it turns into a substance like shellac, would clog the entire fuel system if it is circulated through it. As for putting oil into the cylinders....I would do that. Put a few squirts of Marvel Mystery oil into each cylinder...let it sit in the cylinders for a good day or two (make sure you put the plugs back in so no moisture gets into the cylinders while it's sitting)...then turn the engine by hand (with plugs out so it's easier. After you've turned it buy hand I would suggest doing the following (others may or may not agree with it, but it has worked for alot of engines I have done, especially ones that were seized from rust): 1. After you put the oil into the cylinders, let it sit and cranked it by hand and reinstalled the plugs (very importnat before you crank the engine)...remove the main ignition wire (from coil to distributor) trip the fuel pump switch (to turn the fuel pump off) and crank the engine (using the starter) in spurts, not continuos. Iff you don't turn the fuel pump off than what will happen is gas will be injected into the cylinders and since there is no spark, won't burn it off. This will wash and oil that is on the cylinder walls and cause some severe dmamge. This will get the oil pumped through the engine and coat the cylinder walls with a protective oil film. After cranking it a few times, put the ignition wire back and turn the fuel pump inertia switch back on and start the car up. --- In dmcnews@xxxxxxxxxxx, "Walter" <Whalt@xxxx> wrote: > >snip< I'm also thinking about taking the plugs out and checking to > see if they are fouled.
