Allright I have drained the coolant down and replaced the old heater hose that was for sure a problem. I have the the intake vacuum parts on order from Toyota to eliviate that issue. I think it may be causing some timing issues.

I am going to pull that new tstat and see that it funtioning properlly I always have issues with the damn things every single vehicle I have ever owned old new or otherwise headgaskets too. I have done several hgaskets on my vehicles...

When you bleed the cooling system what is the best method to get the all air out? That is another posibility aside from a leaky heater hose and that could be the problem all in its self. Correct?

I also need to test my oil pressure as it seems lower than I have ever seen it maybe the sending unit. Running down the road on the gas no boost 40+psi?? Not right I say. I remember around 80-psi.

I have so many things that keep running through my head as the car is my pride and joy. I need it. Not about to throw the 5000 Ive spent on it down the drain. JDM. I actually got the engine and tranny from a place in your providence. My old 77 Dodge is worn down and needs to be garaged and loved on alot to make reliable as it once was. Hope to hear back the input is good and more useful than a book thats off on most specs as it is. Thanx again.

I think the cooling system is a closed system. Therefore, you put the coolant in and it pushes the air out. Then you fill the reservoir and run the car for a bit. Checking the external reservoir to ensure it stays full. Shouldn't take long to cycle out the air.

Of course.. thats what I do, it may be incorrect advice.

The best way I've read and done is to "burp" the system. Jack the front of the car up as high as you can, remove the cap, and turn the car on. You'll see air bubbles slowly escaping, and you'll need to keep adding coolant as necessary. This process is long (many hours usually), but necessary. You have to do it this way because the Heater Core is located in a spot that makes it higher than the top of the radiator when the vehilce is level, and air gets trapped in it because of this.
