i have an 87 NA automatic with 230k miles on it and i have already replaced the head gasket less then 5k ago and it has been running perfect since but within the last month or so it has been trying to die and its performance is sad. i start it up and sometimes it starts up fine other times it starts extremely ruff and attempts to die right away but once i get going its fine, except for somedays the temp will shoot up as im driving then drop back down and my heater will start working or the temp will just keep going up and down and my heater wont be working. im also burning oil and loosing coolant somewhere. i just cant pinpoint the problem so to solve it im just going to a complete rebuild and call it good! let me know if you have any other suggestions before i drop $700 into rebuilding it.

did you do anything else besides replacing the headgasket such as machining the mating surfaces?

Looks like you cut corners somewhere.
And your hg is going out again. You may try burping your coolant. Sounds like you have a bubble in there. |

STELLAR.
AutoZone was most certainly who I was going to tell you to take it to. No reason you're wondering why your $hits weak. It maynot be that your supra is a pos. Maybe you just lack knowledge regarding such a technologically advanced auto. |

If you can't determine where you're losing coolant, and your temp is spiking it is likely the hg has gone again.
What did you torque to to? Did you use new headbolts? How is the waterpump? Radiator condition? Clutch fan operation?
