 |

Sheeze, having a hard time getting this nut loose on #2. Somebody really clamped it down and rounded off the nut. Any secret solutions? Maybe an impact wrench?
Just picked up this 71 super beetle to restore. Went to adjust the valves and every one is tight with no lash space at all.

Remove the rocker assembly so it's easier to get visegrips on it.
Replace the nut.

Get a genuine valve adjustment nut - it's special 8.0mm x 1.0mm. Maybe get a new stud too.
That is so ugly, someone surely did NOT know what they were doing !!!!

Steel pushrods get set to a loose zero. Should verify if you have steel or aluminum before completing the job.

Can also remove the "hairpin" clip and take the rocker off to use a vise or something.

Thank you for the advice. Removed the rocker arm and could get a better angle on it with the vise grips. |

So you got the damaged nut removed? You didn't actually say.....

Yep. Got a better angle on it and got it off with the vice grips. I appreciate you guys helping me out.
Now soaking the covers in solvent to try to remove very old gaskets that are stuck hard. I suppose the routine is to attach the new cork gaskets with sealer, let that se tup with clothespins holding them, then grease the other side and put them back on.
I'm studying up on setting the timing; I suspect it's set too hot. I hope some of these procedures result in a cooler running engine to keep that oil light off.
I think you mentioned that the generator needs to be turned clockwise 90 degrees for proper cooling at the fan end. Looks like that would require some work to do. Though I have seen engine pictures where the generator was oriented like mine. Wondering if there are different setups/fans that position that way? Mike |

They are all incorrect Mike.
The generator/alt backing plate has a vent that needs to point toward the ground to cool correctly.
It's that damn lower left screw that is a PITA to remove to orient your gen backing plate correctly. If you can get that one, the rest is easy. Just loosen the hold down clamp and rotate the gen/alt to the correct orientation.

I apply a thin coating of Permatex Aviation to the valve cover, lay in the gasket and then put it on the head.
Never a leak.
You might want to soak the rocker assemblies in a solvent, take them apart and clean them up. Looks like it's been years since they were serviced.

Someone really destroyed that nut. It baffles me how people can eff stuff up.

This is really important. If you have steel pushrods, you don't set them to the standard lash. You want loose zero, or they will be noisy as hell, and beat up the rockers.
If you have standard aluminum rods, set to .006
For the valve cover gaskets, I don't like using any "glue". I just wet both sides with some grease and install. Just enough grease to moisten the cork. I never have leaks with this method. And the gaskets are not destroyed when you need to remove them.
But everyone seems to have their own preferred method. |

They may be steel. I guess aluminum would look like .... aluminum? There was no lash at all on any of them when I started adjusting. If I post a pix of a rod will you be able to tell? And when you say a loose zero do you mean closed but not clamped down? |

A long skinny magnet will answer that question real quick, don't probe the tip, see if it sticks as far down the side of the rod as you can reach.

well I can just remove the rocker and pull the rod out to test with magnet, right? |

Yep, test the middle part, not the tips. Steel will stick, aluminum not.

If they are steel, you want to set them to "loose zero". So contacting the valve tip, but you should be able to spin the rod with your fingers.
The aluminum are just raw aluminum color. Many of the steel ones are a black color. But the magnet test will tell you for sure. |

Ok, closed but loose enough to spin the rod. A good explanation. |
