I have to do the head gasket on my 5SFE and I am going to have the valves done and the head pressure checked and surfaced if needed. My question is what is the max that can be removed from the head before I would have issues with valve to piston clearance. I like the non interference aspect of the 5SFE and would like to keep it that way. But I need to know the max limit so I know whether or not to go ahead with the milling or replace the head if needed.
Thanks |

Factory manual does not give that spec.
Once you have the head off, rotate crank to TDC and measure the height of the piston relative to deck. Then rotate cams through a full cycle and measure the max valve height relative to deck. That will give you the existing clearance (add thickness of compressed head gasket). This post has been edited by dgbldr: Jan 11, 2009 - 10:57 PM |
