QUOTE(stugray @ Sep 26 2013, 08:19 AM)  QUOTE If the adjusters are as you describe, the pedestals are too high, or the pushrods too short or the cam and tappet length is too short. Dont you mean: pedestals to low, pushrods too long, or tappet length too long? Well, I couldn't be sure. I took the description to mean that the screws were driven into the rocker until the slot was buried. But my first thought about the problem is as you describe, with the adjuster screwed out as far as possible - you can run out of swivel room with the elephant's feet that way. In that case I *might* shim the pedestals. I did with my 2056 but it was to obtain the valve pushrod geometry that I wanted - I cut my own push rods after I shimmed the pedestals and used the adjustable pushrod. |

Any confusion is my fault - I was furiously scribbling notes while on the phone with my mechanic. He had in fact suggested 1.7 Rockers and Swivel Feet adjusters from a 911. That got lost in my confused transcription.
We're pretty much all set now. Thanks to all who helped me figure out what I needed. Again, this guy's a very experienced builder but with flat sixes, not T4s. |

I drove my 2056 914 to work today again, and it runs like a top. It wouldn't have but for the advice of people who responded here and others on the board. Thanks!! |

The valve train aspect of the -4 is the biggest difference that people will experience when they are typically working with -6 engines.
This engine can't be treated like something else. |
