Cylinder Head Bolt Caution on Caterpillar 3500 Series Engines |
|
The AERA Technical Committee offers the following information concerning a head bolt caution for Caterpillar 3500 series engines. This information applies to all versions of their diesel and natural gas engines. It’s been reported that service parts inadvertently made inappropriate head bolt parts substitutions. Unfortunately, the substitution was with an inferior bolt quality and may not provide a lasting repair. Dimensionally, the 12 point 8.5” (215.900 mm) bolt was adequate, but the material quality is not for these engine applications. |

Thicker Head Gasket Option for 2002-2008 Mini Cooper 1.6L W11 Engines |
|
The AERA Technical Department offers the following information regarding an additional thickness head gasket for 2002-2008 Mini Cooper 1.6L W11 engines. This information should be considered any time the cylinder head is removed from above subject engines. Before removing the cylinder head, loosen and re-torque each head bolt to ensure thread strength and integrity. There have been many instances of stripped head bolt hole threads in these aluminum cylinder blocks. Determining a complete repair during teardown is well advised rather than finding out during assembly procedures. |

Duramax Head Gasket Sealing |
|
The GM 6.6L Duramax diesel engine has been a popular choice for truck owners over the last 18 years. Several versions have evolved since its inception and the head gaskets have evolved too, leading to some confusion on proper selection. Given that the average book time for replacing head gaskets is around 36-40 hours, you want to ensure that you have the best possible chance for success in sealing to avoid re-doing this very labor-intensive repair. This book time does not consider any machining or overhaul labor that might also be required. |
