Pictures of insulated CCV installation

Here's some pictures from my installation of an insulated CCV. I went with an insulated CCV as I had noticed the white water-oil emulsion sludge that people talk about in the outlet hose of the crankcase. This sludge can freeze and block the CCV system.

I performed the work while I had things apart to fix an oil filter housing leak. I believe you could do it without removing the alternator and oil filter housing, but it made it extra easy. You definitely don't need to remove the intake manifold.

The car is a 2000 528i touring with the M52TU engine.

I've highlighted the CCV hoses and pipes with red.

I haven't indicated everything I disconnected. There's a few wiring support brackets, etc that you'll need to unfasten to get at things.

I should note that the hardest hose to route is the short crooked one that goes up between the 1st and 2nd (out of 6) intake manifold top ducts. I found it easiest attach the new CCV with it's 2 screws first, use a blow dryer to heat up the end of this (and other) hose, and then push the hose on.

Don't bother taking your time taking the old hoses off - just cut the clip and pull them off as you're not going to reuse them.

I added it to the bestlinks (see the part in bold red):

- How to test the crankcase ventilation (aka CCV, CVV, PCV, CPV, & OSV) pressure regulating valve system (1) often causing vacuum leaks due to holes in one or more of the five CCV hoses (1) (2) (3) or whose diaphragm tears, freezes (1) & the CCV often clogs (1) causing pressure in the crankcase and smoke in the exhaust necessitating CCV system overhaul (M54,M54,M54,M54, & M54 observations) (M52,M52) (M52TU) (M62,M62) ('99 528i) ('98 528i); usually with the insulated CCV upgrade (1).
