Unhappy Got the Triple Whammy today! CCV Imploded - Coolant Tank Exploded- ATF Leaking! Pics!

First of all I would like to thank the E46 Gods that made this all happen after I got home and not whiles I was in the middle of nowhere on some highway.

BACK STORY:
Two weeks ago today I got an oil change and I inspected and washed out the entire engine bay myself and everything looked fine. All my fluids were full and topped off and nothing was leaking anywhere I could see.

Since then I've been doing a lot of long daily trips for work and family stuff that went on. I put around 1,500+ miles on the car in about 10 days. This is literally the most I've ever driven in a 2 week period since owning this car.

STORY: Whiles driving this afternoon my low coolant lamp comes on and I sort of knew exactly what that meant so I immediately U-turned for home.

As soon as I parked I saw the infamous blue watery fluid leaking out the bottom.

I quickly jacked up the car and removed the splash shield to reveal a horror show.




1. Coolant pouring out from what looked like a cracked expansion tank (and possible broken hoses):










2. A tremendous amount of oil leaking from under the CCV (Oil Pressure Valve) area:




3. My Power Steering/ATF Fluid Tank (along with its hoses) is clearly not doing its job anymore. Fluid was everywhere, dribbling down the hoses:






And as if for bonus points my OEM Jack broke whiles the car was jacked up:

looks like the hoses here are leaking



Try to loosen move the clamps further up on the reservior and clamp back on tightly. Looks like it's just PS fluid. No CCV implosion. Also check your high pressure PS pump hose for leaks.

Del, glad to hear you got home safely...again! I also think your PS leaks might be why you think ccv exploded. I think cooling is your only real issue...

Also, I hope you didn't get under car with only that jack holding you. If you did that, don't do it again...I hope I saw the corner of a jack stand there, but still, that e-jack is only for Es.

If you have questions, I'll make up answers!

There was oil under the car dripping off the steel plate and steering rack. The only thing that would leak oil there would be the CCV right?

No,

Mine is doing the same thing because the PS high pressure hose is leaking. However, I've just contained the leak by wrapping a water bottle around it stuffed it with rags and secured it zip ties so it doesn't make an oily mess. I've just go to change the shop rags everyonce in a while until I get it replaced.

No, the PS hoses from reservoir will direct the fluid back to the rack. The big hose with the net covering does a really good job of carrying fluid down and back. It might be oil, but it's obvious you have a ps fluid leak. Trim the tops of the reservoir hoses, get new clamps...put new clamp on hose to ps pump, or find the diys on how to get those hoses off by the radiator with proper sized wrenches...maybe Mango wrote about doing that once. Someone did I know.

In any case, that didn't just happen today. Clean up the drips, take care of the cooling system and worry about the ps/oil when you know what's going on with that. You might also have a ccv issue, but that's not in evidence yet. OFHG is another place to look for leaks down there, btw.

If I didn't blow a tire today like you and am waiting on a new set of tires, I'd have volunteered to watch you as you fix it! LOL Srs, though, if you're getting parts and want a hand this weekend, I haven't been to Westchester in a while...would be glad to watch as you fix it! LOL...Maybe I'd help!

The CCV leaking oil will not show up outside the car , you will have oil in the exhaust and intake manifolds though.
The area you're photo'ing is the PS hoses(know to leak alot, the inlet and outlet ones are cheap , high pressure ones is $$$but almost never goes bad) and the oil filter housing(know to leak sometimes, big hassle to change)

all the oil is from PS hoses. all of mine leak or weap fluid in the same way. looks like coolant expansion tank is your primary problem...and a jack replacement.

Funny thing is ET's last along time if you dont overfill the system like most people do and then blame the ET when it blows up.

I was on my 12th year when mine blew , and that was from idling without remembering to plug in the fan(should have lived even longer ^^)

The car is actually in Bklyn for now. There is no way I'm driving it back to Westchester.

I plan on getting my parts from Solid Jake and DIY'ing the Expansion Tank and Hoses right there.

I may consider doing the Water Pump as well. But I want to save up and get a Stewart one

Man Del.. that's some bad luck.
Glad that you go home at least.

Too bad you're not here in Dallas, I have a spare ET you can use.
Let us know what you find out about the oil leak(s).

Good luck.

You should invest in a better jack.

I agree. I always get VERY nervous using those kind of jacks.

Glad you got home okay. That would scare the crap out of me.

noooooooooooooooo!!!!!!!!!!

Here is my input. My memories might be a little faded since the last time I flush and replaced my PS res.

a. the "skinner" PS hose with the most fluid stain is your OUTPUT line (fluid coming out of res into the heat pipe)
b. the transmission line with the fluid stain is your INPUT line (fluid coming into heat exchanging)

I personally think that the output line is leaking and causing ATF to drip down to your swap bar and your transmission line. I recommend buying a hose clamp and try to secure the hose from the res portion. wash and rinse your entire lines with soap and water and check back after a day worth of driving. WIthin a day you can definitely tell where the leak is coming from by seeing the direction of travel of the fluid stain

also...i just looked at your picture again and I saw that your steering rack is covered with brown/black fluid stain. therefore, I think you are right about a leaking CCV. As a result, I think the stain on the transmission hose and steering rack hose is cause by a leaking CCV from the top.

the best way is to use a clean paper towel and wipe off the area. red =ATF and brown = Oil. I know you already know this but I just throwing this out there.

Good luck!

I don't understand how ANYBODY on this forum still has an original expansion tank on their E46. Hope you get it worked out
