The AERA Technical Committee offers the following information regarding identification of camshafts and locations of camshaft caps on 2017-2020 Nissan 3.5L (VQ35DD) engines. Members have reported receiving these cylinder heads disassembled and components loose and unmarked. This presents a challenge for shops to identify which camshaft is the intake or exhaust or the left and right banks for each camshaft. This bulletin will help with the camshaft identification.

The AERA Technical Committee offers the following information regarding the cylinder head installation for Volvo TAD800VE-3 series engines. When installing this cylinder head, the torque procedure is unique. The head torque sequence needs to be followed to ensure proper clamp load is applied to the head gasket. Failure to follow the procedure could lead to premature head gasket failure.

Do you like puzzles? Good, try your hand at this one…

What’s the first thing you do when you start a new puzzle? You look at the front of the box, so you have an idea of the entire picture, then you start to lay out the pieces and look at everything. You study colors, shapes and edges. The same thing happens when you are presented with an engine failure case. You build the puzzle by laying out all the parts, organize the facts, think logically through them, document your findings and see how the pieces fit.

Attention to detail is a key factor in engine failure analysis and a hands-on approach will often find the root cause.

Chuck Lynch and Steve Fox discuss engine-related technical information and machining procedures, as well as invite guest hosts to share their knowledge.
