Missing Bolts?
Hi everybody, I have just bought a 1989 B2200 5 speed. There is a pretty big leak coming from the valve cover and what seems to be two missing bolts right in front of the valve cover itself. I'm hoping you guys can help me identify these missing bolts or point me in the right direction.

See this, about halfway down Mazda B2200 & B2000 Cylinder Head Torque

You definitely do NOT want too-long bolts, you could beak something if you tighten-up.

The front two rocker arm assembly bolts may no longer be available, true. You can post on MazdaTrucking.com and see if someone there has a pair or knows the size. This is not a stud set up, they are bolts, look at my photo above. Sorry, this is the best photo I have right now; disregard that breather hose just hanging there temporarily.
If that fails, measure the depth of the holes, subtract at least 3mm, that's the length of the bolts to look for. Go to Ace Hardware and buy strong metric bolts of that length with 3mm subtracted), believe the thread will be 8.0mm x 1.25mm (if not try 10mm x 1.5mm). Most 8.0mm x 1.25mm metric bolts for sale will have 13mm socket size instead of the Japanese (JIS) standard and that's OK; some Ace have little drawers of JIS standard hardware though with 12mm heads.
Yes, without those two bolts, I could envision an oil leak or worse.
