Damaged spark plug threads in the cylinder head can occur in any type of vehicle. Ford seems to have the most problems, however with all the cars today using aluminum heads; it’s becoming much more common problem. We get questions all the time on application for a wide range of car makes. Manufacturers like Toyota, Lexus, Honda, Acura, BMW Mercedes-Benz, VW, Audi, Mitsubishi, Kia and others can have worn or otherwise damaged spark plug threads. Sometimes the failure is caused by human error, like starting the spark plug crooked and cross threading it. Sometimes the spark plug hole threads are damaged by not tightening the spark plug enough which leads to loosening and vibration which eventually blows the spark plug out of the hole taking some threads with it. Even over-tightening spark plugs can stretch the threads causing damage. Whatever the cause of the spark plug threads getting damaged, we’ve got the kit that will save the cylinder head. Avoid parts store kits that merely put a band-aid on the problem. We have customer’s that need oversize kits after attempting a quick fix from the local parts store, but that’s a different article.

DennisB DenLorsTools.com © Summary: Toyota’s with the 2.4 four cylinder engine have a common issue of blown head gaskets because of the aluminum threads in the block failing for the head bolts. The middle three or four in the back of the head are usually the weak point, which can become stripped. However, we recommend repairing all ten holes to prevent having a repeat head gasket failure due to stripped threads or pulled threads. This also prevents the possibility of the threads failing during the torque process right after putting the new gasket and head back on the block. This can be very frustrating and has happened to our customer’s more than once! Vehicle’s affected are the Toyota Camry, Rav4, Scion, Highlander with the M11x1.5mm head bolts. The repair system that we recommend, the Time Sert 2200 can also be used in any engine that has M11x1.5mm threads because it is a universal kit which can be used on different hole depths.

DenLorsTools.com Summary: Help finding which oversized spark plug thread repair kit to purchase. Spark plug holes that are made too large for regular thread repairs are usually caused by parts store brand thread repair kits that have failed. When the parts store type inserts don’t hold and the spark plug blows back out again the hole is left even larger than before. This requires an oversized thread repair kit. Sometimes the double oversized kit is not big enough. Fortunately, we have a triple oversized kit that repairs even the largest holes up to almost 3/4″. The inside still accepts the regular M14x1.25 spark plug.
