  • S14 baffling in a S13 valve cover

    Has anyone seen this? I have a S13 redtop and have experienced a pretty full catch can at the end or even 3/4ths of the way through a track day.

    The concept is the S14 valve cover has baffling to prevent this and the S13 doesn't.

    Seems like a good idea but with powder coating and you supplying both valve covers, it is still $450. Seems pretty steep to me.

    Thoughts?

    While a good idea, I run a stock oil/air seperator in place of the hybrid cover, to eliminate that happening.

      I bought mine pre swapped by a high school student. Lets just say I've re done almost everything. The sad part is I don't have the stock oil separator and my aftermarket catch can fills up too fast. Any ideas on making it more effective?

        I have a hybrid cover that I bought on here, and sent off for powdercoating. It was done by MA Motorsports.

        It's not cheap, but my wastegate sits in the way of the seperator box, so that's how I rationalized it haha.

          I'd do that for a much more reasonable price if you're interested.

              I just run the vent hose into the bottom of my catch can. oil blows out in the turns and on throttle, then when I let off the gas, the engine vacuum sucks all the oil back in. There's never more than 1/2" of oil in the bottom of my catch can at the end of a race weekend.

                would it be easier to cut your own shields and weld them in to the s13 cover, rather than sourcing the two valve covers and merging them? or does the design of the s13 cover prevent this?

                On my RB i had this problem as well. the stock baffling however, is held by bolts and i replaced it with a Mine's kit. basically some overpriced redesigned shields and foam that you insert beneath the baffling. installation was really easy and it made a world of difference for me.

                  I think boost adds to the issue. Seems like when I am running on 15psi it is much more of a problem then when I run at 11psi.

                    That doesn't surprise me. Even my NA car has tons of blow-by at WOT. under vacuum it sucks it all back in though.
                    You might even consider an oil pan return line from the catch can. that will help vent the crankcase and give the oil that comes out of the valve cover a place to drain back to.

                      Pics please. Are you still running the front of the T to the intake? No oil in the intercoooler?

                        I had horrendous problems at my last (first with this car) track day, I was filling the catch can up 1/2 or better in 20 min sessions and due to it's mounting (to be revised) the long right hander at buttonwillow was dumping oil into the intake to the point that my BOV became an oil sprayer...

                        I have considered using a head as a template to weld the valve cover front and back halves together like this, i didnt know someone was already doing this (and cant believe how proud they are of it.)

                          They actually took the idea from someone else, they give credit to Brian at MA. I had them put a bung on my IC piping for a diverter valve and it was $40. That seemed reasonable to me so I asked how much this was. I was shocked.

                            Come up with a way to add baffling to the S13 one. If you can make a profit with a cost of $300, then you've got a money maker.

                              I have the S13/14 VC Hybrid, and I run a check valve routed into the exhaust. No catch can. I'll eventually put one between the PCV outlet and the intake manifold, but for now this setup will work. The important thing is to get rid of the crank case pressure while under high boost.
