Hi All,
After a month and a half of business trips, I finally got to drive my the 1970 914 that I'm still learning about. One thing is clear, that the restoration was half-assed, and rather than blaming the PO, I have to figure things out the hard way. Hopefully before the fact. I'm trying to not let this leave a bad taste in my mouth of the 914 experience. The recent issue is overheating. This is my first car in the aircooled world, and the car was equipped with a rebuilt 2.0L with the weber downdraft setup in place of the FI. It runs well when warmed up, but during driving, I can't drive it for more than 10 minutes without the gauge being pegged to the red. I'm hearing things of "false air" and such. Pardon my ignorance, but I need a place to start looking for info. Is there any documentation or info out there on how the air cooling is managed, and what hardware is there for me to test / check? Any tips are appreciated. Thanks, Ash |

If you had a $13 USB Endoscope you could look in through the vanes in the fan and see if your flaps were even installed in the fan housing.
It's nice having a borescope in my toolbox... Or you could take the fan off and reach in there. And: Just in my walk over to the shop at lunch, I took a peek and couldn't find the oil pressure switch, instead there is a EMPI oil breather kit, which is tapped from the center oil reservoir on the middle of the cylinder bank. The output of that is looped back into the breather box. The oil pressure switch is down through a hole in the engine tins right next to the distributor. It has nothing to do with the breather box where you pour the oil in. That port is where the stock pressure switch should be installed. If he was a racer, he may have extended that port out of the tin where one woudl install a oil pressure sender. Does the car have an oil pressure gauge? It would be good to know what oil pressures you are seeing when it starts and once it gets "too hot". |
