air breather

 does a 1986 fj1200 have a Air breather or breather element? if so where is it hiding?

Do you mean a Crankcase breather?  If so, (and if you have the stock airbox) it is a small rubber hose going into the bottom of the airbox directly from the crankcase...about 3 or so inches long max.  For those of us that remove the airbox and go to individual air filters (or UNI dual pod air filters) then we stick a small filter on that hose.

yes its the crank case breather I'm looking for. I started getting blow by on the valve cover bolts and firgured maybe the breather tube was plugged or dirty.

More likely the seals around the bolts are dried out and cracked.  It's common.

Watch the torque values on the bolts when you replace them, they are easy to strip.

The seals are soft and no crack's that i seen, when I pulled them apart and cleaned up the mess.

It's not that they harden up or crack to cause leakage...it's that they wear and thin out.  Probably due to the vibration.  One trick I've done in the past when I didn't have new ones to put on is that I took the rubber grommets off (with a small screwdriver - it's a pain in the ass) and then put washers on the bolt as a spacer and put the rubber grommet back on the bolt...because the bolts have a stop flange on them they only go in so far.  It seems that if the rubber grommets lose ANY of their thickness they leak.
