Timing chain tensioner bolt

Well I'm losing sleep on this one. Got the short block put together. 1985 LA360 block. Put cam and timing chain on with a Cloyes tensioner. I only installed three bolts.....did not drill out plate to put the fourth bolt in (bottom right one).
Now I'm wondering if it is ok to leave that bolt out? Does it go into a oil passage or anything?
Thanks for the help.
