I recently read about setting the valve lash at 0.0" in a type IV engine. He was running swivel foot adjusters. How can this be??????? If so it would certainly make the engine quieter.

Yes, I remember that now. Is that a good idea?

QUOTE(Randy G @ Feb 2 2015, 12:30 PM)  Yes, I remember that now. Is that a good idea? Randy It is what is recommended for the Chromoly material. I have them and attempt to set them that way, with swivel foot adjusters. The Chromoly does not expand the same amount as OEM. You adjust with the engine cold. If the foot will spin and my smallest feeler gauge will NOT fit, I call that ZERO. I think I remember reading that the non-swivel foot method would be to attempt to spin the push-rod. Next adjustment cycle I plan to check that. Here is a question for the group. If you did not install Chromoly yourself, how do you know if you have them or not? Let's say, on a recent car purchase, or maybe the PO told you and you want to verify. |

I think CrMo and steel would have about the same expansion rates. I always spin the PR to get zero lash. |
