'90 Blazer - I think I have found my leak. And Prayers have been answered - it seems to have been the least of the scenerios. A simple intake gasket - $17 and a few hours (was hesitant to see exactly what I'd find - plus I labaled all the wiring as I didn't know what went where.)
I removed the intake, cleaned the heads of old gasket material, cleaned the valley of gooey antifreeze/oil sludge, cleaned the intake of both susbtances as well (gasket and goo), and reassembled.
Waited 40 miutes and filled it up until I heard a leak. :eek: :angry: :mad:
Found sorce of leak = top radiator hose that wasn't re-connected.
Stopped that and heard another leak. :eek: :angry: :mad:
That was from the thermostat housing as the engine had filled - so after I popped the hose back on and suctioned the antifreeze out of the thermo housing and removed it to prep for a new gasket - I did the big check. hifty:
The oil pan drain plug had been removed the entire time - a quick look under the truck revealed no antifreeze leaking through the oil pan. :pray: :clap:
so now I have another hour of reconnecting things - gaskets, thermostat, throttle-body, gas lines, hoses, wiring, vaccuum, etc... and I'll fill it with oil (first replacing the drain plug and filter) and see if it fires up! If so, I'll let it run for about 5 minutes and change the oil and filter again. Hopefully it'll be ready to IM very soon!
