Cold start brake fluid trick
Cold start brake fluid trick
Ive got a first gen gsl-se. I was going thru the tech threads when i landed a thread that sounded just like the problems i am having. the car sat for two weeks in the freezing cold. Now when i go to start it....nothing. I was reading a post about putting brake fluid in the vacuum line going to the intake manifold used for the brake booster. now my question is does this trick work on a first gen 13b cause i noticed this thread was for a 3rd. any help please
NO NO NO!!! Brake fluid eats the seals, so you will toast your motor!
If the problem is that the motor is flooded, grab a turkey baster from your local grocery store and a can of Seafoam. Remove the bottom spark plugs and squirt a couple of ounces of the Seafoam in there. She should start right up.
However, you should also verify that you actually have spark at the plugs (both leading and trailing). And do some more searching and reading in the 1st gen technical section.
Good luck, and I sincerely hope you haven't used the brake fluid yet.

It does seem that way, but it really does work better than anything I've ever tried.
My old motor was way down on compression, and I live in Michigan so it gets pretty cold. Combine that with a racing carb, and you get a lot of experience with flooded motors.
Using ATF or Oil to deflood can also degrade (and possibly foul) your spark plugs. The Seafoam actually cleans up the plugs, and eats the carbon out to increase compression. Once you get it started using this method, the motor will actually run stronger than it did before you flooded it. That, at least, has been my experience.
Whenever I put a can of Seafoam in the gas tank (every couple of months, or prior to a race) I always leave an ounce or so in the can, just in case I need to get a rotary deflooded.

So does this work the same way as a regular deflood, with the ATF I put it directly into the rotar housing, so i would do about an ounce sea foam into each of the housings right.

Brake fluid is ethylene glycol based. (PolyEthylene Glycol) It's very similar to antifreeze, so it won't harm the coolant seals. It needs to have the ability to absorb water (So that water doesn't collect in the brake cylinders and corrode the walls.)
The oil seals are stronger than the coolant seals. (In fact, oil or petroleum products in the brake system will harm brake seals... Oil is more damaging to rubber compounds used in seals than Ethylene Glycol.)
And there have been cases of master cylinders and brake boosters failing causing the situation where brake fluid is sucked into the engine.
I'd move for it won't harm anything, but it won't do anything useful either.

Turn the pulley a second time and then put a third ounce in...
Remember, these engines have triangles inside, you need to get each side of the triangle.
