# 5 cylinder fowls out plugs. What's causing this problem.? Loss of power . ideals very low runs crappy
low compression...bad rings...bad valve guide...BAD VALVE SEAL....intake manifold gasket leak...cracked head....bad plugs/gap/plug wire....TELL YOU WHAT...U DIDNT SAY WHEN OR HOW LONG....BUT I BET IF YOU TAKE THAT PLUG AND REPLACE IT WITH ONE 2-3 HEAT RANGES HOTTER THAT WILL FIX IT ...FOR ABOUT $2.00...SAY IF YOU HAVE A >R 43 GO UP TO A >R 45 !!!
If you only have one bad cylinder then try a hotter plug which will help burn off the excess oil. How many miles are on the car?
Is it oil fouled or gasoline fouled? If oil fouled it's probably bad rings, or bad valve guide seal on that cylinder. Using a hotter plug, as suggested above should stop the fouling. You can also try a spark plug anti-fouler on that plug as well. If it's gasoline fouled you probably have a bad fuel injector on that cylinder. HTH. - Jim
