Blown Head Gasket Symptoms!

Dejvid1785 · 01-27-2006, 01:13 AM

I have a 88 NA supra, i'm trying to figure out if my thermostat is out or is my head gasket blown? What usually happens or what symptoms there are when your head gasket is blown?

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.

My cars tail pipe looks like it's a steam engine. lol, I'm replacing my MHG with a composite one tomorrow.

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!

Try to take out the old thermostat and punch out the insides of it and then replace it. Then you will know that it is not your thermostat.

Does your car use up any water? If so, and it probably does, then it could be your head gasket. I blew two head gaskets, on two different engines in the past year. You need to check your distributor!!! That is what caused both of my engines to blow. There are three different modules in the inside of the distributor that you need to check. You can test them in a few minutes, with a meter. I used my old distributor in the new engine I bought, which was a big mistake. I do not want you to make the same one. My car was smoking and burning oil. Also, when I checked the timing on my car, it was fine. But, when I advanced the engine, the timing went off the chart. This was do to two of the modules in the distributor going bad. A new distributor is only $256.00, from Toyota. Let me know if this helped you. David

My 87 Supra has a blown head gasket and ive heard about certain head gaskets that help with the tourque spec issue Toyota had back in the day. I would like to know what people would recomend for me to get for a head gasket.
