Just realized I was adding project info to a WTB add....so moving it to the garage.
It hit me today that since I'm using L-Jet heads, I need to add venting for the crankcase. Is the best method to drill and tap for a threaded insert? I've been reviewing breather boxes too. Not sure which I want. I'll be using cabin heat so if the breather puts out fumes, I'm putting it into the trunk. For the breather set up, I may need an early oil filler unit with the port on it. Anyone have one handy? I have the '75 LJet unit, can I modify this to work? Or can I use the larger diameter port that is t'd off the filler neck? Since I'll have to have this machining done, anything else I should do, like relocating the spark plug hole? Is that really a significant upgrade? The valves were re-done, 42x36. Got Weber 40's coming, 71mm crank/rods, Webcam 86b. Need to swap out the KB pistons with ones for the correct wrist pin ht. Also going to install 8mm rocker studs. maybe longer oil pump studs for the 30mm Shadek. Need to get the crank polished and rotating assembly balanced. I think in my spare '74 motor lies a fan with all the blades. Need to pull that out too. I will definitely need to get some of the wiring issues sorted out going from LJet FI to carbs. Feel like this is starting to come together... smile.gif |

AFAIK all the 914 heads had the boss for the tube. That looks like the 2L bus heads that are on my engine. The only reason I didn't post a pic of mine is that it isn't a 914 head, lol.
You have the right spot. We used about a 60 degree angle and kept the tube longer than stock so it was easier to attach the hose. The only problem with that head is the aluminum is a little thinner without the boss so use plenty of JB Weld. You will also need to start with a small drill and work up to the 1/2" gradually. Also, start the drill near vertical and once you have it started, change the angle to what you want. It will be tough to keep it in the exact spot so maybe start a little further to the left than you want to end up. |
