Really... then why does #1 not have the same problems since it also has the longer exhaust....?Peter said:This is actually myth. It has more to do with combining an overly compromised ignition advance curve with an unbalanced intake pre-heat system and a long exhaust manifold. Most of this was cured when VW used improved advance mechanisms and, subsequently, more efficient intake pre-heating.
The position of the oil cooler had virtually nothing to do with it.
Why does doing a "Dog House" conversion with no other changes reduce head and oil temps?
