I have blown head gasket symptoms in my car. There's white smoke billowing out the tail pipe sometimes. It runs great after the start. I need help with a temporay fix or a permanent fix, but I don't have alot of money on hand. This is the first RX7 I've ever owned and will never own another type of car, I love the Weinkle Whine lol. PLEASE HELP TO FIX MY CAR! Thanks everyone.

 

i hope u know that u dont have a head gasket, the only permanent fix would be to rebuild it? what part of cali u live in? there is TONS of people there that would be willing to help you, probally in one day... try going to mazdatrix.com or racingbeat.com or www.rotaryressurection.com for some motors...

 

It sounds like you may have a blown coolant seal. The seals go in between the rotor housings and the front, intermediate, and rear plates to seal the coolant from getting out of the engine or into the combustion chamber. The only way to really permanently fix is to rebuild. You could try the coolant seal fix, though:

The coolant seal problem usually comes about if the engine has been overheated. If the engine overheats, the housings can warp and pinch the seal in such a way that the coolant leaks into the combustion chamber.

The other possibility is there are coolant o-rings in between the intake manifold and the engine. When these get old and brittle, they can let coolant into the intake of the engine producing the smoke that you are describing. You should look into this option first. The seals are cheap to replace, and it doesn't take that much work to do (remove carb, manifold, and related hardware).

You can try to start the car with the rad cap of and look for bubbles. This may help to tell you if it is the intake seals or the coolant seals that are the problem.

Hope this helps.

Thanks for the info. Let me start from the begining, My friend was driving the car and so much pressure built up in the radiator that it blew off the radiator resivour cap. I replaced the radiator, the thermostat, the cap, the rotor, and the plugs. I used Stop Leak for the radiator and it stoped the white smoke coming out the tail pipe. It has become difficult to start the car, but when it runs, it runs awsome. Witht he radiator cap off the engin pushes the coolant out the top of the radiator. I know there's still a problem, I don't have alot of cash on hand, but I need to be mobile, where should I start? Thanks!

 

Find a good used engine or learn how to rebuild one youself.

 

Well, you definitely have a blown coolant seal from your description. I agree with trochoid: either find a good used engine or try to rebuild what you have. There is no other way around it.

You may be better of with a used engine as your housings may be warped. In addition, you may have rust on the rotors, etc. from letting coolant/water sitting in the housing while it isn't running.
