I received in my -12AN PCV fitting from JPC Racing as well. They are a very high quality little piece IMO.
The reason why I got these was because Darren who has a 318ci N/A road race car was having excessive blow by issues. A few suggestions thrown his way was to run a vacuum pump or to go with larger AN hoses from the valvetrain to the catch can to try and prevent it from choking the motor by not dispensing the blow by fast enough. Another person chimed in saying that they have run -12 lines to the Peterson Catch can without issues.
This just seemed like the easier thing to do than to try and setup a vacuum pump that was capable of handling road course duty without if failing. The less moving parts the better. Who knows whether my car would run into the issues that Darren's car was having in terms of blow by, but if I could stop an issue before it presented itself then I figured I would go ahead and jump on it. In doing so I removed the -10 AN lines from my Peterson Breather Can and got to work assembling some -12AN hoses.
I ended up getting the Aeroquip Startlite Hose for this application as it is 45% lighter than their Stainless Steel hoses. Granted the weight difference is extremely nominal, .16lb-ft for the startlight compared to .29 lb-ft. for the stainless steel but racecar & Matt D style weight savings, so I went with the Startlight.
I went ahead and put them in and started working on cutting the AN hoses to length.
I grabbed my Earls Hose cutter that I bought and began measuring the hoses to cut to length. For this I used Aeroquip's assembly instructions except that I used Mineral Oil instead of their assmebly lube as that is what I have seen most people use while assembling the hoses.
After I cut my hoses I went ahead and grabbed my AN fittings that I bought from Phenix Industries. These are made out of 6061 Aluminum. Their elbows are made of one solid piece of billet aluminum and they appear to be quality pieces and they are Made in the USA.
I then grabbed my Koul Tool and pressed the hose into the fitting. This part was so simple and if you plan on assembling a bunch of hoses, I would say this is a nice tool to have. You just put the fitting into the tool and you just push the hose in the other end and boom, all nice and seated. I then put a piece of scotch tape on the end of the hose right up against the fitting so that I can tell if the hose had pushed out during assembly.
I then put the other half of the fitting into the aluminum vice insert as such, and placed some mineral oil on the fitting and pressed it in, then spun it onto the threads.
You want to try and put some pressure on the hose as you are screwing the fittings together. When you are putting them together I have been told that you want to leave a very small gap between the fittings, something like the thickness of your fingernail is a good gauge to go by. As you can see the hose did push out a little bit so I twisted and pushed the hose at the same time and got it seated back all the way into the end of the fitting.
I then went out and grabbed my Peterson Breather Tank and wanted to give it some TLC. As you can see, it looks like it has seen some better days so I just wanted to clean it up a little bit to make it look a bit nicer.
I grabbed a rag and this stuff I picked up at Carlisle called Chrome it and started working on the Breather Tank. I think it came out decent, nothing spectacular although I think it looks a lot better then it did before I started out on it. I grabbed my hoses and some Teflon Tape and ran the Teflon Tape on the -12AN bungs that go into the Peterson Breather Tank and tightened everything up.
This is how it looks all assembled on Kelly from BMR's car, very nice
. I hope he doesn't mind me whoring out his picture a little bit.
