That my friend is a base head gasket leak. I'd replace that and if the problem still exists then your cylinder surface is warped or cracked. When you pull the head off inspect it closely

I also assume your having power issues as well.

can i ruin anything by lightly driving it and
 
does the engine have to come out for this
 
ill get the pdf
Depends on the compression. You could lose alot of oil if it runs for lengthy amount of time. Could overheat. Many things can happen but to catch it early enough is key. The engine can stay. The head is 8 or more bolts. Comes off easily.

      91 quadrunner lt4wd shifting issue
      By Joeguy
      After i did my rebuild it seems to not want to shift well. I think the cable is alright, and when it does shift its nice and solid. I have to basically use my hand to shift and i have to pull or push it very far, like max travel, to get it to shift. I also tried adjusting the clutch set screw. Any ideas where to go next, or maybe i should just grab a new cable to try.

      Fuel issue
      By Dsluder
      I am having an issue with a hs500. I bought it broken and have been trying to get it running. It seems to be starving for fuel. If I put my hand over the intake it will crank but will not run for very long because I'm not able to get the correct airflow with my hand. The things I have done so far are. Replaced the fuel pump, fuel filter, mass airflow sensor, idle air adjuster, fuel injector, cleaned the throttle body, replaced the ecu, and still the same issue. I notice the injector does not spray when removed from the head. I dont know if that is common. 
       
      I am out of ideas on what to do next. I have removed the fuel line from the injector and it is getting plenty of fuel. If anyone has an idea on what could possibly be the issue I would be happy to try anything at this point.
