Milky oil cap.
Milky dipstick.
Coolant loss.
Steam out of exhaust.

That's the stuff I saw yesterday after I drove my car for the 1st time in over a month, after replacing the head gasket. Yessssss.

Oh, and when you drain the oil, it should be nice and watered down too.
I guess you had a water jacket to oil channel leak.
Not all BHG's are like this, I think most are the cylinder to water jacket leak type.

With my BHG, the oil was perfect. It came to a point where the combustion gasses would just cause the car to spit out coolant even in idle, yet the oil and coolant never mixed or had a leak amongst each other.

I don't have any smoke out of the exhaust or milky oil, but i am losing coolant!! Could that still be thermostat or something else? My temp gauge never stays still it sits up top showing that its over heating but the car isn't over heating and is driveable and suddenly it jumps back down, if anybody knows answer me. Thanx!

Delivering it home with a friend driving the Supra for the first time. I drop gears and make a scream from the twin pipes flowing down this pony's flanks and it takes off like it's tail's on fire.

I look back when the Honda gets to its tap-out and the Supra's only two lengths behind. No one I've let ride my bike has told me its slow, they've all loved the thing. That car is a good thing indeed.

I have the problem with the temp gauge, but luckily no problems. While im driving it shoots back and forth. Its either cold or overheating or where it should be. Most of the time it says its really hot. But its still good and driveable. So its just a malfunction with the temp gauge. Not much of a nuisance so i dont worry about it. My gas gauge is like this too. I dont pay attention to the needle but when that little orange light comes on, its definitely time to get gas. Goodluck and hope its not the BHG.

Can anybody tell me how to test that to see if it really is the HG, is there an easy way to test it out?

Do you lose coolant from that area? A very cheap way to see if you are losing coolant from that area is to put a container (soda bottle) after the overflow dump tube. If the overflow dump tube spits out coolant in the bottle...well, that would indicate that combustion gasses are forcing the coolant out of the system. That would mean you have a BHG in that case.
A cheap test. I learned that trick from Duane (upgradedsupra) so he gets merit for that idea....

Also, the guy that put that Cygnus site up, has some awesome write ups!
http://www.cygnusx1.net/supra/techtips.html

And within that, there is a good write up on BHG's.

I am currently in the process of determining weather or not i have the dreadded BHG. the guy that had the car before me said he put a metal head gasket on it, so i'm hoping that it's not that. I have some information though I'd like to share.

The heater core was replaced and the antifreeze that was put in was the orange kind from prestone. i have been putting that in it because it sounded like a good coolant. and the coolant was bubbling over. last night i went to buy some more at the auto parts store and the guy behind the counter almost took my hands off. WOAH he said don't put that in it. It'll gum up. it's specifically for GM vehicles!!!

i have already put two jugs of this in my car and now i'm gonna try to flush my cooling systtem with some anti gunk stuff and replace my thermostat as i suspect that it is gummed up and stuck. hopefully i can fix the problem


hope noone else has put this in their poor supra
