Thanks Jim
Can anyone tell me what this small tube (circled) is for? I don't have this on my '66.

Thank you Jim
The pre-heat tube would of appeared on 69 MY.
Does anyone have a photo for a 911T engine? Anyone have a pair of used ones for sale?
Thanks for the link mate but I'm trying to source cheaper ones as the postage cost will be a killer...Cheers!
My '67 Normal had the original heat exchangers with "chokes" in them. I still have them but SSI's are on the car.
FWIW: Porsche experienced cracking issues in some heat exchangers noted in a bulletin dated December 16, 1966. The bulletin is 2 pages and gives a description of the work scope and labor time.
Here is an excerpt regarding the seriousness of the problem:
"The introduction of such gasses into the passenger compartment may be unpleasant and, under certain circumstances, will present a significant safety risk. Therefore, the program described below must be carried out as quickly as possible"
In another bulletin Porsche also allowed customers to upgrade to the 911-S heat exchangers however they charged for this because performance was increased.
The cost was $65 each. Porsche claimed an increase of 10-12 DIN horsepower with the "S" heat exchangers.
The heat exchangers in question were: 911.211.011.00 left 911.211.012.01 right.
The new heat exchangers were: 901.211.011.01 left 911.211.012.02 right.
The "optional" S heat exchanger part numbers were: 901.211.017 left 901.211.018 right.
