ok so today i noticed i have a VERY small and unusual leak.

its right about the block stamp, right where the transmission meets the block.

here is the thing..i cant tell what fluid it is. its just a bubble that comes out every couple seconds. kinda like when you put water on a leaky tire.

there isnt alot of buildup on the block either..a little but its too contaminated with dirt for me to tell what fluid it is.

my question is...wth could be leaking right there? and why is it a "bubble" out of where the transmission meets....there shouldnt be any air pushing out of there.

i do lose a little coolant (burning) and a little oil...dunno where its going..no aparent leaks.

the last thing i did was replace a rear main seal.

thanks for any help. if any can be had

 

bump for possible ideas

 

What does the fluid smell like? It could be oil, coolant or tranny oil. I would check your tranny oil level to see if you loosing oil from there.

 

doubt its tranny fluid.......do check what it smells like.

 

well.... if its comeing out where the block meets the trans, it coulb be trans fliud leaking out.
has the trans been taken out recently???
it is highly reccommended to put hondabond on all of the surface on where the trans mounts on to the block.

 

Bad rear oil seal?

i had the trans off about a month ago to replace a rear main seal.

i have had no leaks whatsoever since then. or at least any that leave a puddle.

i tried smelling it, but i couldn't tell....not enough sitting on the block.

i didn't think that part of the transmission is supposed to have fluid in it anyways.

and why would it be coming out at the top portion of the tranny only?

is it possible i did some damage when putting the tranny back on that could allow coolant to leak there? coolant is the only fluid i really get low on. takes about 1 month to go from full to low on the reservoir

 

why the hell would you do that? There's nothing to seal there.

my thoughts exactly

 

Well, since your flywheel and clutch is spinning around it could fling the fluid upwards. There is a seal on the transmission end that prevents our tranny oil from coming out. Maybe breather hole clogged or obstructed?

Another possibility could be a leaking head gasket

im hoping not...it burns a little coolant as it is...new headgasket and milled head...done before i got the motor. i noticed the leak when the car was cold.

mabey if i get it to operating temps it will show more.

thanks for the help guys...sorry i cant be more descriptive

 

99% of the time, it's this:

too bad he is talking about a B series. i have a D

the vtec solenoid is on the other side of the motor. and i dont have an exhaust cam seal. i have a cam seal...for both intake and exhaust, because im SOHC.

anyways
here is a pic of where its at...and the bubble...and a video of my exhaust blowing white something.

i dunno if its condensation or coolant because i have a hole in my exhaust that could allow a nice amount of moisture in.

 

There are no fluids close to that seam where the bubble is coming from. It must be getting there from somewhere else.

Could it be dripping down from the dizzy o-ring and flowwing along the crack between the engine/tranny, then just coming out at that point?

 

it could be from anywhere in that area..headgasket, dizzy o ring....but why would it be bubbling out of there...

shouldnt be ANY pressure in there right?

 

maybe i should try cleaning up my block a little and seeing if i can find a trail

mabey if i overtightened that tranny bolt that's right there when i did my rear main i cracked the block? i dunno how close that is to a coolant passage or if that is even possible.

Right, there is no pressure behind that seam.

I would definately clean that area up and keep an eye on it, that's the best way to find the source of the leak.

That's not close enough to a coolant passage or oil passage. I really doubt your block is cracked, if it were, it wouldn't be just a little bubble.

 

thanks man. ill be back with more info as i can figure it out.

I've had this <U>exact</U> problem happen to me. I'm also d16z6 like you are. B-series, D-series, it doesn't matter. Cam seals, VTEC solenoid seals, dizzy O-ring, etc. It's all located in the same area, and it all can go bad and leak oil onto the exact area you're describing. I've had this happen multiple times on the exact same motor as you and successfully found it to be one or more of the things I listed/what's listed in the link I gave you. But what would I know, right?

First, stop being bullheaded and atleast entertain advice someone else gives you. Second, use some degreaser or brake cleaner, clean the area up real good, and start diagnosing again.

It's merely factual at this point: there are <U>no</U> fluids that run through that area of the block/tranny housing where your leak is, so it's time to start looking at fluids in/around/above the area. Gravity is probably pulling oil down from a leaky cam seal/dizzy O-ring/etc. Like I said, that's usually the case, but if you choose to just ignore this as atleast a possibility, then that's your problem.
