Please HELP! Cooling system issues

[craiggroves91]

Hey guys I need some help ASAP!

So this morning on the way to the berkley marina meet and someone pulled next to me to let me know I was leaking something, so I pull over and my car is spitting water out everywhere.
So back up I have been driving this car for more than two weeks and have taken some decently long trips, trips just as far as I got this morning. I drove it yesterday further than I got today. This morning before departure I added water wetter to the system. I was hoping I just overfilled the system and it was spitting out excess, but it continues to spit water out of the reservoir.

Air bubbles can be seen shooting up out of the lowest hose on the reservoir and the hose gets quite hot. This guy


So I got a tow home and tested the T-stat and it seems to work fine, but to rule it out completely I ran the car without it and it still spits water out.

Maybe water pump failure? The car has a brand new Stewart performance water pump

Any ideas?

EDIT: So when I last had my intake manifold off I bent this metal hose down to allow for manifold clearance, is it possible I bent it too much and it is kinked enough to build up heat in that lower line and boil?
The best picture I could get of it:

The odd thing is I drove with it like this yesterday quite far and it was fine.
thanks

could be a couple of things however worst case scenario u got a head gasket letting go.

is the hoses hot coming out of the radiator? thermostat properly installed?

you can run car and squeeze the coolant hose while car is running and it should build pressure where you are squeezing it. It will not do this if your waterpump is no longer working.

is the bottom hose hot also? thermo properly installed?

Well I know compression numbers may not tell everything, but when I bought the engine they were fine across the board and since its been driving fine I assume its fine.

The bottom hose does get hot yes. The thermostat should be properly installed since its been working fine. I believe it was in with the springs facing the engine

and the thermo should be ruled out if it does the same thing with no thermo in

u need to pressurize the coolant system and verify it bleeds down while car isnt running this should also reveal where its leaking. You can rent a pressure tester at advance auto for free. Does the oil still look like normal oil? any oil in the coolant reservoir?

Okay I'll look into that! thanks

oil seems to look like oil and water looks like water. No chocolate milkshake.

that's good, at advance you just have to give them whatever the price of the tool is which u can put on a credit card, and they will let you return it for a full refund. I wouldn't drive the car anymore until u locate the problem

Yeah I have rented from them before, pretty cool.

I won't be driving it. I'm really hoping its not the headgasket :/

So what will the pressure tester tell me? If there is a leak anywhere?

[Stiggy]

Pressure tester shows u where the leak iz...

Also try a new /different pressure cap on the expansion tank,and check that the line from the radiator to expansion tank is not plugged where it connects to expansion tank. GL

if the pressure does not hold, you have a leak. also test the expansion tank cap.

How do I test the cap?

I ran it without the cap and it still did it

Basically hook up the pressure tester to the expansion tank opening where the cap screws on (the connectors are different for different cars obviously, make sure to get the one for bmws and the older bmws use different connectors compared to the newer ones) and pump it up to about 15 psi. After pumping it up check all over the engine bay for leaks and then check the gauge to see if the psi has dropped.

I would also check under your oil cap for signs of coolant, this would most likely indicate that you have a blown HG. Before hooking up the pressure tester I would wipe away all the residue.

How does your car run?

Sounds simple enough.
I'm really thinking its that kinked heater line though.
I only run distilled water and water wetter. So the only thing I might see on my car is condensation, but it looks fine. Car runs strong!

hmmm this makes me think the HG is blown. do a leak down test, the compressed air from the test should push bubbles into the cooling system if its blown.



the cap is screwed onto a pressure tester. you pump the pressure tester to the PSI the cap is rated to. if it holds, the cap is good, if it bleeds down the cap is bad.

Its just odd the HG would blow after adding water wetter. A compression test should tell me if its blown too?
The numbers were fine when I bought the engine

I think that kinked heater line is causing that section of the water to get hot and then boil
