So the Machinist says that the new intake valve is .039 larger than the hole it is supposed to go into. What is the size +.000 to put the guide in. 2.0L head. And I guess I have the wrong Exhaust. Need 15mm guide vice 13mm
Gosh this is fun (IMG:style_emoticons/default/rolleyes.gif) |

that's what I do! Group: Members Posts: 20,065 Joined: 27-December 02 From: Port Hope, Ontario Member No.: 26 Region Association: Canada |
A couple of thousands press fit, you (I) don’t heat the head, or chill the guides. I have a special tool and I drive them in with an air hammer. I rarely have to size them after install and if I do I use a ball broach.
If you need to install an OS guide, then the bore must be reamed to size first. The whole trick is removing them! The guide must be cored so you don’t damage the bore. P.S. I’ve probably done several thousand by now. |
