Big adventure for me. Have never done this before by myself. Taking the engine out of my 70 914-6.
I got everything, I think, disconnected and/or removed today -- except the half shafts. My memory is failing me. 5-10 years ago, I bought and installed bolts that were drilled for safety wires, which I did. Now I can't remember if they were 6mm Allen, which seems to fit if I can get it squarely in, or was there a spline fitting? I found a single spline thing with my Allen sockets that is just about the same size, perhaps 8. Something tells me it might have been purchased for those bolts. I can get the 6mm in there, but I am not sure that is it and I don't want to round the inside of the fastener. The spline thing may be too big or I may not have it square. Scared to pound it in. The bolts are tight. Aren't they always? They got a dose of pbBlaster for the night. I'll finish this tomorrow, I hope. Are the OEM bolts 6mm? Did anyone here install the drilled bolts and can you tell me, Allen or spline? What size? Any tricks getting them loose? A universal with an extension? (I just have headers) Use an impact wrench? I must have done this part of the job before, but the memory thing . . . I seem to recall torque wrenching them, too. What should they be torqued to? Thanks in advance. |

8mm =31 ft/lb
10mm =55 ft/lb It's a special hardness bolt. |

I don't have gaskets and was suppose to get them today but have not heard from the guy. Anybody else run without gaskets? Essential or not? |
