So I think I already know whats going on, but pls give some feedback if I'm right or not. 97 GS overheats when not on freeway, and coolant boils in overflow. When Idling, you can hear air being forced into the resevoir. The car smokes (blue, oil) when stopped, or driving on the streets.

Both have been increasing together in intensity and frequency, I am almost positive that this is a blown HG (and pray head isn't warped), causing both and a faulty thermostat may have led to the initial overheat and blown HG.

Just bought car at auction, I have not looked into it much, its been in and out of the body shop and seems to be the case. I should probably do a comp test (obviously), but the two incidents seem to go hand in hand, to me at least.

Let me know what you all think, and let me know if you know and really good, reasonable machine shops in the Tacoma/Lacey/Ft Lewis, WA area.

Thanks and peace............

If it only overheats while sitting still or going slow, your fan(s) may not be coming on. Do you know if they are? Does your gauge show when it's overheating? If it overheated once, there's a chance the thermostat is stuck and not letting water flow properly now. Have you added water to it since you could hear air going into the overflow?

And yes, you probably do have a blown head gasket. If the head's warped, you can have it milled for flatness at a machine shop.

Does it overheat while on the freeway, or cruising at higher speeds (40+)?
