Assembling my 2.0L / T4. with a fresh WebCam 86b with 106º lobe centers. Cam drive is straight cut gears with slotted holes for timing. Question for those of you who have done a set up with these parameters. Did you do the positive stop TDC with heads on or off, with a stop bolt or dial indicator? Through the plug hole with heads on? Because of the Lobe Center specs considering retarding 1º from cam card spec.
Thoughts? Thx. |

I've done it both ways. I think the best way was heads off with a dial indicator. Once I found tdc with dial indicator I used a short, skinny metal ruler to scratch a tdc mark on the flywheel relative to the location of the engine stand next to flywheel. I would recheck tdc with the ruler when needed.
