Ok, so I got home tonight and was having a weird gurgling sound from the engine, found a heater hose to the firewall leaking, clamp had somehow moved up, or was never connected in the first place. Which would explain why I was losing coolant for a while.
But after repairing I filled her up with coolant/water (about a liter) and fired it up, the truck was still hot and I revved it up to about 1700 rpm and there was a white smoke constant and when snapped there was quick white smoke than a plume of white smokeas the rest of the exhaust was pushed out.
This concerned me, so I drove around the block with my head out the window staring at the exhaut (I live in a rurual area no traffic
put it in neutral and revved it, happened again with the smoke, than I really punched it, put in neutral again and nothing, no more smoke.
Im wondering if someone might help me diagnose my problem? Its a 1992 3vze v6 engine. I checked the oil/tranny no sign of coolant, looked in the tailpipe with a mirror and no white coolant burn marks.
Im thinking something like a stuck EGR valve/PCV valve.
Please help!
