Hi all
Engine is a 1973 2.0 with a 2056 build. I purchased a cam that was more aggressive for spirited driving no track and just large enough to maintain the car running fuel injection DJet. New heads with no vents. purchased the oil tower and air box for a 1975/76 as the bigger breather opening was recommended. I am still experiencing some oil leaks one that sits at the base of the head near the number 4 spark plug. Plug is not leaking. Also some oil on the thermostat spring mechanism. Valve covers have had inner lip welded and 914 rubber cork gaskets. I bought this canister to help with the pressure and hopefully remedy the oil leaks.  I have been unable to find an example of how to route the hoses for this when installed. Any advice or pointing me in the right direction would be appreciated. |

Wow, good catch. I've seen that video before and just rewatched it. Somehow missed it the last time.
It's hard to tell, but the one he says he's putting in a 356 doesn't seem to have the hole (middle case of the 3). I agree that it's probably some kind of crankcase ventilation. It's pretty much at the highest point on the case, which is where you want to vent the case. It's where we have ours (on the plastic housing that has the oil fill cap on top. Some run a fitting or hose to/through the oil fill cap, but that seems like a pain to remove every time you need to add oil. One other possibility is that it could be a way to add oil to the motor if you're running either an upright system or a flat fan system. But, since he's said that the head vents (if available on your motor or valve covers) should be plugged, I'm voting for it being crankcase ventilation. Because where else would you p ut a vent?? BTW our next motor is a 2615, have all the parts. Just need the time to work on it. Of the 1.7, 1.8 and 2.0 liter cases in the hoard, we have 3 core 1.7 liter cases and two of them are "W" cases. The plan is for the 2615 project to use a "W" case because it's the strongest of them. |
