Anyway, it is the Board of the Curate or not, it helps !!!!!!!

Greetings and thanks before hand !!!!
My problem is as follows, I have a Toyota Corolla Model 91 with a 4A-FE engine, which is driving me foam by radiator and I have a strange failure that does not allow me to put the engine ready (because it always has a failure) Change spark plugs, filters and check the intake but no stability, then I preceded the radiator to drain (to rule To make the pruba defionitive, after doing this I realized that I had foam again (this could mean that it is definitely a cycle problem, but the question is because I do not mix water with oil in the radiator, because it does not heat up, because I do not mix the engine of the engine with water (such as changing color, losing vizcity, etc.) Then having so many because I do not have a confirm Help, please take out someone of such uncertainty.

To get out of the insertion, take out the spark plugs, check if they are with water or oxidized, and the other test you can do is start with the radiator lid if it jumps the water is but it is cooked, if the spark plugs are like oxidized or they have a precious water, if the level of water lowers or increases mysteriously.

I have already done the turn on with the lid of the radiator removed and it really does not jump water when lighting, but as I mentioned before it is a lot of foam and also climbs when accelerating (and I think that the fact that the water rises does not mean anything because it is usually normal due to the turbulence of the water inside the channels of the radiator) apart from that I have taken out the spark plugs and apparent Not having any of those symptoms, I continue with the doubts, please give me some more advice I thank you from hand.

Good compi. I think I am quite sure of what is happening to you. What you have there is a slight compression leakage for the lid joint, so the engine starts and unemployment, most likely it does not unemployment immediately but after a couple of minutes, since the refrigeration circuit is filled with press What hot covers the hole where the cap goes with your hand, if there is a minimum compression escape you will notice because it will be pushing your hand little by little but constantly, most likely it is that the machine matches when you take your hand and it brace again when you put it again and the circuit is filled with compression. The escape must be minimal and that is why it does not mix the fluids. But if you are like this, you will burst everything. If this is so, recommendation, change together and brush the flat face to the lid. SALUDOS COMPI

My friend thanks for interest in my problem, I really thank you, I will start the tests that you have recommended but beforehand I tell you that it is very logical and intelligent what you tell me poerque I have noticed that when I remove the plug (with the vehicle in progress) the vehicle is stabilized, anyway I will do everything you recommend me, and I will let you know, thank you.
