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 |

I've never seen a BB plumbed in that fashion. (IMG:style_emoticons/default/agree.gif) How is it breathing without some way to vent? I've always seen them either with a vent on the breather, or with a hose run back to the carb air filter. What's that hose that's going above the center of the engine case? The one zip tied to the throttle cable. Would also be interested to see a shot of the underside of the engine on the passenger side. Just to verify that the stock oil cooler is still there. Also, here's a writeup on removing the oil pressure relief valve. It's on the underside of the engine near the oil filter. It looks like a big flat head screw. http://www.ephotomotion.com/914engine/page08.html It's something you might want to check. Tangerine Racing sells an improved version of it in case yours is worn out. http://www.tangerineracing.com/oilpressurerelief.htm I have it installed on my car. Works great. |

How is it breathing without some way to vent? The breather box is supposed to have a gap on the top lid to allow for venting. There should be a foam piece in the box that traps the oil vapors and lets the oil drain back into the case with the engine off. (IMG:style_emoticons/default/popcorn[1].gif) |

Wow- you guys are incredible! I love how supportive the vintage car community is, like the ones for my bmw 2002's and mini's, as compared to new cars which bash you for modifications that aren't to "their" liking. Cheers to that!
I would be more than happy to purchase the entire flap/thermostat kit from anybody + shipping. Please email me at aashish.dalal@gmail.com. Thanks! |
