Hi. I have had my 12aT sitting for a few years now. I just changed all the fluids expect the gas and it is almost ready to be started. The gas tan has been on empty, so should I still drain it or would it be to just add new gas? I know the engine isn't locked but should I pour oil or ATF down the carb before starting? Should I use starter fluid? I dont want to mess anything thing up. Any suggestion would be greatly appreciated.

Q. Do you have an Rx7 you're trying to restore? A seized engine? a car that's been sitting for a few years? Wondering what the "ATF Treatment" is and how to do it without killing your engine?

Thanks for the link. But I still have a question. Since my engine is not seized up, should i still pour a bit of oil in the engine, just to give it some lube. The reason im asking is the oil metering lines have no oil in them. Im not sure how long they take to start pumping oil in to the engine?

Thanks.

 

You can "prime" your metering lines by getting a cheap plastic syringe from a hobby store, disconnecting both ends of the line, and squirting oil gently into the line til it's full. (If you leave the bottom end connected, back-pressure prevents you from getting much oil in.)

For the hyper-paranoid like me, you can also use the syringe to drip a lil oil into the carb on the first start after a long (months) shutdown. The key is "little;" the OMP only puts out something like 2CC's over 6 minutes time at 2000rpm. Too much oil = fouled plugs.

The OMP lines will drain down very slowly if the car is not run regularly.

 

If you have old gas in that tank, get as much out of there as possible. Drain it preferably. Check your filter because the old gas there may be clogging that as it turns to varnish as well. I wouldn't try to start it until you can make sure that gas is delivered all the way to the carb at the right pressure and flowing good. Also make sure your carb is not gummed up. Sitting for few years means that anywhere gas has been sitting is likely gummy or blocked like in float bowls or accel pumps.

I wouldn't worry about the oil for the OMP too much it will catch up quick enough.

Once its running make sure theres no coolant leaks as well.

 

i WOULD DO THE ATF TREATMENT BUT WOULD PULL THE SPARK PLUGS THEN CRANK THE ENGINE LET LET SET TO LET THE OIL WORK IT WAY IN. THEN START GOOD LUCK

 

I would not recommend the use of ATF. Seafoam works much better at getting a rotary started, cleans the apex seals up, cleans the spark plugs, and won't harm your seals. Just dump a couple of ounces down the carb and give it a go....

 

Always fun to see a relight. Get rid of all the old swill that you can and swap the filter. Might want to replace the fuel lines at the carb while it's drained.

 

With Seafoam on a Gslse, would you just just dump it in the spark plug holes ? how much do you recommend ?

 

to the o.p., does your car have an original 12A turbo j-spec engine, is it a pacific avatar, or is it a custom setup?

 

^^ What he said.

Plus if your really paranoid just run your first tank of gas with premix oil. 100:1 or 1 ounce per gallon is pretty standard.

 

If the car is already running, then just add a can to a partial tank of gas. If you are using the Seafoam to get the car started, then yes, you can use a turkey baster to shoot it into the spark plug holes...

 

on a 13b could you let a vacum line suck the seafoam in while its running?

 

If it's running, then it should go in the gas tank (in my opinion). I've tried adding it directly to the engine through a vac line, or by dumping it down the carb, but I think its just a waste. What do you suppose all that white smoke out the exhaust is?

I think you get more bang for your money if you just put it into the tank. And nobody will call the fire department that way either.

 

Yes. With the car running you allow it to "suck" 1/3 of the regular sized can of seafoam. It will likely stall, so have someone help you so you can keep it going by giving it gas. It will then smoke like hell for a bit, then you are done.

Read the side of the can of seafoam, it will tell you all of the ways it can be used.


For the thread starter. Drain the tank of that old stuff, consider running new fuel lines. Larger ones that this point may not be a bad idea since it is turbo. Do a tune up, and sea foam the motor. Flush the rad, and run some water and white vinegar in it to operating temp. to clean out the rad, etc. Then flush out that mix and refill with coolant water mixture.

I would consider running 1/3 of the seafoam in the old oil for a few minutes to clean the engine out, and then immediately drain and change the oil and filter as well.

Or, you could just let me have the car if you like....
