plugged ccv hose :(

[rynmls]

I really did it this time. My "elephant hose" plugged with ice causing pressure to build up in my block. now my car leaks crazy amounts of oil. this ever happen to anyone else? With my luck it's the rear main seal and I'll have to pull the trans and find that my clutch is ruined as well. DAMN! what do you guys think is leaking? I'll have it on a lift sunday.

Crappy

How was your hose set up? Running behind the engine and hanging out onto the ground?

I haven't had any freeze up problems yet. I have the hose running at the back of the engine tied close to the block, and ending in a little catch can above the lower engine cover. Seems to do the trick, but when it starts getting really cold, -20C, I worry a bit.

I don't have a clue which seal would have likely gone.

Good luck.

the hose was running behind the engine, I didn't have a catch can on it. there was about 4" of ice in it. I think I blew an oilseal in the turbo. it puffs blue smoke when it idles. I hope it's just oil blow by some how. I also notice a bit of run away now.

maybe I'll just add more oil and it'll fix itself

oh and yes, keep an eye on the bottom of that hose! the temp here is 0 fahrenheit so it's about the same where you are.

I went out in the freezing cold today and checked the hose. No restriction. There was a little puddle of ice on the lower engine cover and some in the bottom of my catch can, but only a few little flakes of ice in the hose.

I think what has kept mine from freezing is that it ends right beside the exhaust downpipe, so as long as the car gets up to proper temps that hose is kept rather toasty.

Is your car still leaking?

After you fix the leak, make a pressure relief in it, just a couple of #40 drilled holes halfway up. If you drill rubber at small diameters, you will create a kind of hole that will not flow easily, be sort of closed most of the time, but that will open up under slight pressure so you don't blow important seals anymore!

On my 5 cyl diesel Mercedes 300D, which had a similar but more crude system than ours (unregulated, just orifices, no valves). I created a small pressure relief hose out of 1/8" i.d. nylon tubing. I ran it from a drilled hole in the vent hose between the head cover and manifold and the rear axle area, using the already present line clamps to anchor it. No more leaks. This car had SERIOUS blow-by. If you took the oil fill cap off, with it running, the vapor huffed out like a steam locomotive, reaching to the hood!

Sorry to hear of this catastrophy!

well, I think the car is going to be okay. I've been keeping a close eye on the garage floor, oil level and the end of the ccv pipe. and everything is back to normal! What a relief. I was thinking new turbo at the least. I'm going to make a catch can so this will not happen again. WHEW!

Good to hear. I had a feeling it might resolve itself. If your doing the catchcan setup you might as well drill a couple small holes midway down, as Saabguru suggested, then you definately won't have to worry any more. I'll do this next time I have a chance.

I've been keeping a real close eye and ear on the car these last few days. It's been REALLY cold! No freezup probs yet. They're calling for a high of -17C/1F tommorow. Yikes.
