Catch Can setup HELP!

[Justin_l_]

To prevent this, it is much better to weld two 90* fittings to the top of the VC on each corner on the passenger side, like this:

This also allows you to keep the PCV valve if you want, and the original VC breather port can be tapped and used for a sensor to log the CC pressure.

There was another thread where a person had this exact same issue, for the same reason. I'll see if I can dig it up.

I think I remember reading somewhere about clearance issues when running fittings off the top of the valve cover like that, it that true?

Depends on the car and the fittings. I had to flatten one brace on the hood slightly on my 1G, but it wasn't a big deal.

I should be able to get back to this soon to see if cleaning the can and filling that little bit of missing metal works. I welded it up yesterday and I'm going to try this before working on the setup above.

FWIW - I pulled my own can and lines off last night for some cleaning and inspection. Your pics in post # 13 don't look bad at all compared to what I had.

E85 + cold weather = some nasty shit

The good news is...it was in the can and not the intake or engine oil.

Shouldn't he have another line with a check valve in it running back to intake manifold? ie pcv location to catch can then catch can back to intake manni. Then, one more line from catch can to hard intake pipe between maf and turbo?

If OP was running a PCV valve, then yes... a check valve in line with it would be a good idea. But he's completely deleted the PCV valve functionality, and is using that port purely for pressure relief while under boost.

Any updates?

Calan I am curious to know is this amount of oil/water normal and how much oil are you using.

My motor is pretty loose, but it changes with the season and fuel. This is the most I've seen, but I've been driving the car a lot this winter on E85. There isn't a whole lot of oil at all...it's mostly water and the slimy E85/water/oil compound that gets cooked up.

In the summer and on pump gas, the can fills much more slowly and it's more of an oil/fuel mix with very little water.
