6G72 24v

This page refers to the 24 valve 6G72 V6 used in the TE through TJ Magna. For information on the 12 valve V6 used in the Second Generation Magna/Verada see 6G72 12v. For other versions of this engine see 6G7x family.

The 24-valve 6G72 is one of several variants of the 6G72 engine. As with it's 12 valve sibling used in the TR/TS series it is a 3.0 litre 60º V6 with single belt driven overhead camshafts.

The differences between the 24 and 12 valve SOHC 6G72 are:

• Mounts on the left-hand side of the engine bay (see the Engine side mount page for more information)
• 4 valves per cylinder (24 valves in total)
• Two-piece alluminium and steel oil pan
• Spark plugs located centrally above the combustion chamber
• Metal head gaskets
• Discontinued Variable Length Inlet Runners.

Two variations of the 24 valve SOHC 6G72 engine were used in the Magna. One was used from the TE through TH models and the other in the TJ Magna. The latter used different camshafts which retarded the timing slightly to improve emissions.

The 24 valve SOHC 6G72 was built solely at Lonsdale and was exported throughout the world.
