hey all,
about 8 months ago i rolled the 4runner on its roof for about 15 minutes. got a couple buddies to help push it over and then towed it to my house. i took out the spark plugs and turned the engine over like everyone says to do after rolling. after this i changed the oil but NOT the spark plugs. engine ran fine for about 7 months, then it started misfiring really bad. i replaced the plugs and tried to clean out the plug chamber? this completely solved the problem and got rid of any misfiring...until yesterday it started the same horrible misfiring. i took out the plugs today and they were pretty dirty and tried to wipe them off cuz there was some oil on em. then i put em back in and its still misfiring. is there anything else that would make it misfire so much? i think tommorow im gonna have to get new plugs but i dont want to have to replace them every few months. is there any real way to clean out the "chamber" so that it stays clean? sorry this is so long but i dont know waht to do right now. thanks in advance

Is it the tips of the plugs that are getting fouled up, or is there oil getting into the spark plug tube where the wire connects to the plugs?

well the tips are caked with oil but the tube is also oily. is there a way to clean in there? i rolled up shop towels and stuck them down there and thought i got most of it but? i will go get new plugs tommorow and see what that does

use some carb cleaner/brake cleaner and blast it down there. then stick a paper towel rapped screwdriver down there and swash it around.

You may need to remove the spark plug tubes and clean them and the area in the head they seal in really well and then reinstall the tubes using the proper sealant. The proceedure for this can be found in the FSM.
