I did not know there are three marks on timing gear

When i went to adjust my valves on 09te310 i lined up the marks on timing gear to top of head grove. Now i see on one of the threads there are three and the double mark is tdc. I do not remember witch one i used. Should i go back and redo it with the tdc one or does any think the other marks should be ok for this time. Live and learn.

If thats true, I'd re-do it. Using the wrong timing marks could largely change your valve openings, thus changing your valve clearance....

IIRC, if you're set at the correct marks, all four cam lobes will be pointing the same angle (intakes canted forward, exhaust canted rearward) toward the center of the head. That's not scientific but helps to back up questionable marks. Hope this helps ya.

it kinda sounded like you adjusted the clearence. If so then ABSOLUTELY check. If you just checked them than I would still re-check for peice of mind that you surely know whether thay are in/out of spec. Seems likely that you checked at the right point though- because the results did not alert you or were off-

I just checked mine last weekend- I did it the Dave Hopkins way (watch timeing of valves check in/ex individually/ not tdc) and the Husky dot way/ tdc. same results- I did that for piece of mind/double check. When I "looked" for the dots I was just looking at the lobes both turned inward/up as Ioneater described- and "some dots" lining up. I didn't even worry about there being 2. Cause that was the right spot.

Thanks they where out .001. They dont take long to check. I am just getting old and lazy.
