Here is mine when it was in my 95


Pretty much the same parts as Joe. I just used a longer legged 45, and a different boot. All the parts I used are from Napa.

if you don't want to buy new hoses, and want the filter more square on the fender, take the black flexible hose off of the original filter housing (goes from filter box to aluminum pipe at valve cover) turn it around, cut it off to the first rib (the cut off piece will be tapered) , leaving the rib. then carefully cut the blocks from between the first and second rib, this will allow the factory clamp to fit down in the grove. set the filter in place and set the 45 degree pipe over it and the hose and mark it for cutting

I dont have a pic of the stock setup but, I used a 4" piece of pipe and made a 45 degree angle with it. It's not as pretty as the ones shown above, but it works great and cheap.

Vents blow by into the atmosphere instead of your turbo.

It makes the intake air cooler because you are not dumping the hot crankcase gas into the intake.

I would think that would minimal.... The main thing with CCV is the oil residue that it can promote IC boots to blow off during high boost conditions with a IC.

You need to start small and work your way up when diagnosing. As always, check your filters and replace if necessary. It might be possible that your kitty is clogged up as well.

We need to know more information than its putting out white and black smoke going up a hill. What are the operating temps? Does it do it every time? Any modifications to the engine?
