There is only one timing mark on my 1.8 fan. It's visible through a notch on the rear side of the fan via the inspection port. Pelican parts info says the mark is TDC. Auto Atlanta says it's 7.5 degrees BTDC in the 914 tech tips 700 book. Can someone please tell me which is correct? I need to make sure the timing and valves are adjusted properly.

We had a 1.8 liter ljet motor in a 914 (now replaced with a 2 liter).
It needed a TDC marking for timing purposes. Why? Because a previous owner had put carbs on it. So, if an ljet fan ends up on your motor, do yourself a big favor and mark TDC. |

(IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/beerchug.gif) oh yeah thats different. i used to own a type 3 variant (twin carb aussie zero emissions spec) back half a life time ago. i bet the 1.8 twin carb euro 914s have a TDC mark on their timing fans. but never seen one. can't say for sure. but am guessing they did. i think i have an engine shot of the 1.8 twin carb held in porsche museum which shows the tune up sticker. might try and dig it up. the timing sticker if legible might indicate what is on those cars. (IMG:style_emoticons/default/beerchug.gif) VW!!!!!!! american emissions regs. !!!!!!! its all about setting the car for emissions back then and in the good old USA.
