Sometimes the manufacturer will put the spec's along with the adjustment procedure. You may have to read into the procedure a bit to find the spec's.

try calling Tacoma Diesel 253-922-8171. They have been very helpful on my 30 year old 3QM30.

Need Valve lash spec Yanmar 3JH3E
Unbelievably my owners manual and service manual both fail to give a valve adjustment spec. A lot of similar sized engines from yanmar spec at .006" to .010". I believe this may be the case for my engine also, but it would be nice to see it in print or confirmed from someone who has a manual that actually states this.
