86GXL

I read a TON of ATF threads and since my compres numbers came up to 60 all around on both rotors i figured i'd try the ol' ATF trick to see if i can get those numbers a little higher just till i get my new motor... ANYWAY to the point of this thread. I found the perfect thing to squirt it in the spark plug holes and at least 75% of the ATF ran back out. Why??? Well i went ahead and put it in all 3 chambers and it ran out every time. Why did it just come back out????

because you probably put way too much in?....

or you are using the wrong spark plug hole (bottom I think) which only has a pin hole that goes into the chamber.

I put very small doses in

Its a hell of a lot easier to pour it down the inlet tract hey....
and no for the love of god before anyone asks it will NOT hydrolock your engine...

Also contrarry to popular belif ATF does not actually eat the carbon off rotors.. so it only MIGHT unstick your seal springs a tiny bit, MAYBE.
It also does not hurt any of the internal rubbers from my very unscientiffic test i did with it.

bottom line? it does SWEET F A! except make a huuuuge ammount of smoke..

Inlet tract???

White_FC

Well yes, sorry inlet manifold.
Inlet tract could be anywhere from the filter to the end of the manifold...

I added mine after the throttle body... where the BAC valve went.

86-88 NON TURBO models can utilize a single vacuum hose to inject the atf/oil. In fact there are 2 locations to do so. You can not use a funnel in these methods, you will need a pump to force fluid in.
1) Locate the upper intake manifold, the ribbed aluminum casting that has 13B injection printed on it.
2) On the front end of that intake are 3 vacuum hoses. One is larger than the other 2, the larger one is on top.
3) Remove the larger one. You're going to pump the atf/oil into this HOSE slowly. This hose splits into 4, and leads to all the oil injectors on the block, which inject directly into each combustion chamber. Doing this will not interfere with the oiling duties of the oil injectors later.
4) Pump slowly when doing this, as these are small orifices youre pushing though.
5) 3-4 pumps should do it. Replace the hose and start the car.
The other method for 86-88 NT's:
1) On the same upper intake, on the drivers side, there is a large vacuum hose(about 1") leading in below the BAC. Above that is a small, 3mm vacuum hose.
2) Remove it, you can pump into this nipple, which will squirt atf/oil into both primary intake runners evenly, though this method might require more atf to be injectors(to run down into the engine) and longer to work(to allow time to traverse the length of the intake).

Ahh, you beat me to it Although, I never figured out the 3mm he refers to .. pictures would be nice.

Me either, but then, we don't know as much as some of the guys! Right or wrong, I removed the BAC to get ATF in
