Some of you may know in the 4AFC engine there is a short bit of piping going from the top of the heat shield over the exhaust manifold, to the intake pipe. I have done a bit of research and found out what this pipe does. It's designed for the colder European climates, because the weather can be so cold, the engine would struggle to warm up. Getting that extra bit of heat from the exhaust and warming up the air going into the engine helps the engine to warm up.
I've come to the conclusion that Melbourne doesn't get THAT cold, so when I get my AE92 in the next few weeks, I would like to remove this pipe, and plug up the hole left in the intake. Looking for advice from anyone else who has removed this pipe, were there any problems you incurred? Does the engine run differently on cold starts? Is it a fairly easy and straight forward process?
Thanks in advance for your help.
Luke.
