my first rx-7
ok i managed to get the car and i am very happy with it. from what the guy says, or what a mechanic told him it gets coolant in the intake somehow. what would be the sighns of that? any ideas why? maby gasket? also i am new to these cars not so much that i dont know how they work, however if there is any info anyone can think of for basic regular mantencance things to check and regyular things to do please let me know i want to take very good care of this.

There should be coolant in the intake. JK., but its most likely the intake o-ring seals is bad. Are you getting any leaking coolant around the intake manifold? Look up facts search for general maint. etc.

Go buy some Chemi Weld and add it to the coolant via the radiator. Chemi Weld is a chemical that helps sealant of leaks. Note, it is only a short term fix, although I've heard of this quick fix, lasting a long time. Good Luck, Jay

I would get the intake gasket kit from Autozone or Advance Auto Parts. These only run about $7 to $11 and include the intake gasket AND the O rings. No need to halfway slap something together that is a pain in the rear to get to, like the intake manifold, when if can be fixed well for less than $15.
Just my $.02 from someone who just through doing this project last week.
I would also avoid any kind of additive to the coolant until you make sure that the leak is not coming from the gasket or O rings. If it is an internal engine coolant leak the try some of the additive but also realize that this would only be a very temporary fix and a rebuild of the motor is not many miles down the road for you.
Good Luck!

Intake o-ring coolant leaks will often show up above or below where the intake mates to the block. The o-rings are located between the primary and secondary ports (2 of them).
If the leak is at the bottom of the intake, it will drip on the exhaust and burn off. If at the top is will usually puddle, then evaporate.
Do not start throwing a coolant sealer until you have determined the cause of the leak. A coolant sealer is a stop gap measure to prolong a failing engine, until a rebuild or replacement is possible. If reusing the same core for the rebuild, you then have to remove all of the sealant from the internal cooling passages, not worth it in my book.
The other coolant leak you need to worry about is the internal seals. If these fail, a rebuild is required. Easist test for this is to remove the radiator cap, start the engine cold and look for 'champane' bubbles in the radiator, after the engine has reached operating temps.
Since you are new, a word of caution, overheating is usually instant death for a rotary. They will not tolerate overheating like a piston engine will. If you see any signs of overheating, the temp gauge starts going up for no reason, or the low coolant light or buzzer comes on, address the issue immediately!
This does not mean try and drive the car home and then fix it as one of my customers tried to do. He lost the motor. This means stop and pop the hood and find the cause, right there and then. Always carry extra oil and 50/50 antifreeze with you, at a minimum.
