Bleeding CAC Boot

Although this a regular issue on these engines, nothing special about an oil soaked boot, I figured I caught this one right as it was about to fail. I did a lot of work a couple weeks ago on the engine, and inspected the boots. I noted they were a bit oil soaked and a crack on the outside that was starting. (Inside looked good.) Ordered a new set of BD Diesel boots, and here we are 2 to 3 weeks later to install......and the boot is absolutely bleeding oil! Took 18 days to go from slight crack appearing, to this:





Ah...look at the trace of oil in the cooler down below. See how clean it is? That's due to the bypass filter kit I installed with the Amsoil filter!

Those were the factory Ford boots from 2006, 173,800+ miles on them. I wasn't thinking when i ordered the set.....I only have the 2 boots. The other side is the factory plastic pipe that is a b*tch to get on and off. Either I'll have to find an aftermarket pipe that uses boots. or sell the extra 2 boots and 4 clamps they sent.

use a hair dryer, heat gun, or hold the plastic pipe in front of a space heater while you turn it...slips right on every time

Why do you think your oil bypass filter put oil in the cac?


Edit: why do you think the oil bypass kit KEEPS OIL OUT of your cac?

I think perhaps two issues are being mistakenly combined: The OPs said he thinks his bypass oil filter is the reason why the residual oil in the CAC looks clean (not black). I dont think he's saying the bypass filter is the source of the oil.

No problem, ....I just read the responses :)

Back when I tore into the engine a few weeks ago, for the work listed in my sig line, I had some normal pitch black oil in there. A normal result from the PCV system. Here we are a few weeks later, having run the oil bypass filter, and the same amount of oil in there, but clean oil. I'm really impressed with that Amsoil filter. Only now that I am changing boots, did I discover that even the crankcase vented oil appears clean. The old boot by the turbo was so saturated, i squeezed it like a sponge and black oil from weeks ago dripped out.....

I'll remember that.......wish i would have thought about it a few weeks ago! Is the factory arrangement with that plastic pipe pretty good, or is there an advantage to going with an aftermarket pipe and using 2 boots?

The plastic pipes are prone to cracking. You can replace it with an early model aluminum pipe.

Cool...just ordered the '03 intercooler pipe from Sunrise Ford, one of the powerstroke.org sponsors. Put DIESEl in the promo code as directed in their posting, and sure enough there's $10 off! Free shipping as well. Came to $97.44, a deal I figure. Now I have something to use my other 2 BD Diesel boots and clamps on!

When the time comes to install it.....I'll have to sneak my wifes blow dryer to the garage :woot:

If it still puts up a fight getting that damn plastic pipe off like before, I'm breaking out the Dremel tool....:rofl:

just make sure you thoroughly clean all cac hose connections with brake clean. you don't want them blowing off on you, otherwise you might shart yourself.:haha:
