why? Wouldn't I check the end play once I reinstall it? What would checking it before removal tell me? _________________ 1963 Ragtop |

Bentley pg58 engine. B.7. Endplay( .0027-.0051). Wear limit(.006) inches any more than this indicates wear at # 1 thrust bearing . It will only get worse and may/ will cause case damage. Check if thrust bearing is moving in case journal
That is from orange bentley 70-79.
Hope this makes sense. _________________ "Albatross"! |

Back to the valve issue. As I was cleaning the heads, I was able to look closer at the valve stems.
exhaust valve stem #3 has pitting on the end.
The only info I could find on that, is that points towards adjustment screw issues. correct?
Exhaust valve #4 looks to have a shave/cut off the tip, towards the side. What does this tell me?

If the adjusting screw tips are pitted up that will wear on the valve stems.
Try putting the rocker arm back on that head and see how the screws and stems align up. _________________ In Stereo, Where Available! |

If you look at WW's website for 63 beetles and later, they have a rubber valve, part number 311115541 that goes on the bottom of the oil filler tube.
what purpose does this have? Why not leave the tube wide open?

The clever shape allows condensed water to drip out, while not letting dirt and water thrown up from the road to get in.

Something to be aware of with those is that some manufacturers leave the end sealed, and you have to take a knife and cut it open yourself. |

Once I am ready to put the heads back on the engine, are there steps that need to be done before doing so?
I will be resealing the jugs back on to the case using gray RTV. The jugs were already loose once I removed the head. I'll try and clean the surfaces as best as I can, before applying new. _________________ 1963 Ragtop |

Just clean the heads as best you can, and follow the torque sequences shown in the manual. Torque both heads at same time, back and forth.
And heads are the same, left and right. And stretch the pushrod tubes before installing, and evenly, using your thumbs. And make sure to install the important little tins under the cylinders before you install the pushrod tubes. _________________ 1970 VW (owned since 1972) and 1971 VW Convertible (owned since 1976), second owner of each.

I did buy new push rod tubes. The existing ones were rusting, not leaking, but rusting. Since I had the pushrods out and having to replace one, I figured I'd replace the tubes. So is it safe to expand the tubes completely and then shrink as needed? Is there a science to it? If they can easily be expanded, how exactly will they stay tight once installed? I'm sure it will make sense once I begin installing
I do have those little cylinder tins. Something so small and simple, yet important.
Any major concerns if outside of jugs have surface rust? _________________ 1963 Ragtop |

no, I will be doing that tomorrow.

I see 14, and 25 ft-lbs, depending on bolt size when torquing. sound about right? _________________ 1963 Ragtop |

Just sent one back.
Yes, torque varies with thread size. Bigger means more torque. _________________ In Stereo, Where Available! |

SO, if the cylinders come out from the case, then should the old paper gasket get picked out of there, clean up the mating surfaces, and then seal with only RTV? |

Precisely. The paper gaskets are more of a nuisance than they are worth.
Just don't goop on the RTV. Sometimes too much of a good thing can make matters way worse.
Good Luck. _________________ I have learned over the years.

When it comes to the rtv. I cleaned up the base of the cylinders today. The paper gaskets we're installed. But all removed and cleaned. When applying the rtv, are we talking a small bead, or more of a thin smear? Does it matter if you place the rtv on the case, or on the thin lip on the base of the cylinder? _________________ 1963 Ragtop |

No paper gasket.
Apply the RTV to the cylinder bases. If you put it on the case. There's a chance that it will get inside the engine. That would be very bad!
Good Luck.
EDIT: Yes a small enough bead to seal the cylinder base to the case.
As soon as you have all of the cylinders installed and sealed. Put the heads on and torque them down.
After that. Take the wife out for dinner or whatever she want's to do.
Just don't mess with the engine while the RTV cures. _________________ I have learned over the years.
