So tonight I had to swap back my SRI and my Forge motorsport BPV valve because I have to go to the dealer tomorrow. When I took my forge BPV off I noticed that it had a bunch of what seems like oil/grease in it. I have only had the bpv on their for 2 weeks so there is no way that it is blow by and the stock BPV had NO oil/grease whatsoever in it. Here is a picture. WTF is going on Forge?

Mine did the same thing when it was new. My recirc pipe was filled with it. Cleaned it up and havent seen it again with over 15k miles. Could be excess grease blowing out from when it was assembled.

Our valves are assembled with Mobile 380GE fully synthetic grease which is red. The "shit" you see is mostly oil from your PCV system. Call the EPA if you have an issue with it, you probably have half a cup sitting in your intercooler and charge pipes.

Hahahahaha, that's funny stuff.

On a different note, to the original poster: You can and it is also recommended that you install a catch can for this type of stuff. MS6's are known to get a lot of oil build-up in the intercooler without one.

It's something I'll be doing very shortly myself.

Then why is it that my old BPV has no buildup whatsoever in it?

The oil is diluting the grease to the point that it is thin enough to blow through the pipes, or put another way, the grease is thickening the oil enough to prevent it from reaching the engine. With the factory valve, there being no grease, most of the oil will reach the engine or collect in low spots in the charge pipes.

In a perfect world the oil could be used to lubricate the valves but there are too many contaminants for that to work. This is why we recommend that the valves be serviced periodically.

Eventual, after many heat cycles, the oil that has collected will turn to sludge where it has collected in large amounts and will yellow and turn into something akin to varnish on the surfaces with smaller accumulations. The intake valves and valve-seats will be coated with varnish and cruddy deposits. Catch-cans are a good idea if engineered properly.

The OEM bypass valve is a plastic body and piston. With the Forge you've got a metal-on-metal design. Grease usually helps keep friction down.

it is possible that the timing just worked out that way. these motors to tend to trash a pcv valve and perhaps it just happened to malfunction around the same time you put in the forge

seems too much of perfect timing and if there was blow by going through the stock bpv it would still stick to the inside of the plastic bpv to a certain extent.

So clean your BPV out and regrease it...seems like a pretty simple solution to me.

How often should they be serviced? I noticed lately its nowhere as loud as it was when I first got it. Not that its an issue but could it also be a sign that it should be cleaned?

I don't know a specific interval, but every other oil change, I tear it apart, clean all mating surfaces, check all o-rings, and re grease with synthetic grease. Hasn't had a problem yet.
