how do i adjust the valve lash my book sys to torque to 136 in lbs but my wrench is only in ft lbs
as stated by another valve lash is the gap space between the rocker arm end and the valve top. I too recomend getting an inch pound torque wrench especially when setting a ft lb wrench to 11.33 would be very rough.(not accurate)
valve lash is a small gap between roker arm and valve bridge or valve top its main reson if any meatel heat then expend. it proper gap according to manual book intake valve gap less according to exhaust valve and fuel intake and exhaust out depend on valve gap you aslo called valve lash use for fuel setting.how time fuel in and how time exhaust out.

valve lash is a small gap between the rocker arm and the valve stem as the engine heats up the gap gets tighter due to expansion of valve train parts. To set the lash correctly find the gap that is recommended and use a feeler gauge to set. loosen the jam nut that holds the adjustable screw and set the screw to point where the guage has a slight drag on it. all this is done at the rocker arm and takes practice to get the feel of it. This must be done while the valves ARE CLOSED and the engine rotated to the correct position for that cylinder. Once the gap is set using the feeler guage, hold the adjustable screw still and tighten the jamb nut to the in./lbs. speced. In./lbs are a smaller value than ft/lbs. Find a torque wrench that has the smaller increments. If your not sure, find someone who HAS done this before and get them to assist you. Again, it must be done with the engine rotated to the correct spot. Usually around TDC for that cylinder being adjusted. Once set, test again with the feeler guage and see if the lash changed during the tightening of the jamb nut. If so, set again till lash has a slight drag. This means that you can slide the feeler guage in the gap and its not to loose nor to tight
