86 , 2.9 Overheating

Tried pressure test, will not hold pressure but I can't find a leak. Tried block tested, came out AOK. Losing fluid but absoutly no leakage. Where is the fluid going ?? When it overheats it comes back through the resevior. HELP !!!!

Did you look at the weep hole at the bottom of the waterpump shaft seal? Some years back had a buddy with a BII who thought he had a cracked head/block because he was mysteriously loosing coolant. Turned out to be a bad mechanical seal in the water pump that would only leak when the truck was running and hot. Hope this helps.
