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 tha 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.

Ford spark plug blowouts and how to repair using a spark plug thread repair kit are one of our most covered topics here at DenLorsTools.com and at our sister site WiseAutoTools.com.

(We also had a recent customer drop a tap from a parts store kit into the cylinder). Having to pull a head just to get a thread insert out is not an easy pill to swallow. After we thought about it for a moment… hey there is a way to get it out without removing the cylinder head!

DenLorsTools.com Summary: Motor vehicle air conditioning questions answered from all over the world by a master air conditioning technician in Florida. Simple to understand terms are used to resolve issues and to help the reader understand problems with their car’s Air con system (A/C system). Low gas (refrigerant) is the most common problem a car’s aircon system could have, but it’s not always the issue. One shouldn’dt assume that the solution is always to top-up (top off) a system. A re-gas that adds too much R134A only causes more problems. Many garages will do a free pressure check. However, simply checking the pressure readings is not a foolproof test of the air conditioning system’s health. But, a knowledgeable motor vehicle technician can make a good evaluation of the A/C’s performance based on the readings and a visual inspection of the components. After evaluation, a regas (recharge) may be done or a more accurate fill of refrigerant can be performed by removing the remaining refrigerant, vacuuming the system down and recharging with the vehicle’s specified amount of gas.
