UPR valve cover fittings and filler cap replacement and some cheap fittings and catch can off eBay. Some say do it...some say don’t. I just wanted to experiment. Any feedback from people that have done it on a street car? I’ve got a road trip coming up in a couple of weeks...figured I’d throw it all on and see what happens.

 

I wasn’t a huge fan of that fabricated can...ordered this billet version just now.

 

Don't you want some suction on the system? Especially with a whipple? Or am I missing what that filter is for on the can?

 

Can't see any problem with it except tossing a CEL for an open crank vent. PVC systems are fairly new pollution control measure, well started in the 1970's anyway. Prior to that all vehicles and internal combustion engines just vented to atmosphere some filtered many not. KM

 

None of the blown Mustang guys have and codes...hopefully this is the same. If I get one I’ll just have the light killed in the tune.

 

The car guys seem to be ok...I guess I’ll find out. lol

 

WAG on my part but the valve cover filter is for incoming air, the tank catch can and top filter venting the crankcase, with careful positioning of one way valves a positive venting is guaranteed. KM

 

The oil cap replacement has a check valve...it’s to not let anything in but let that extra out under high boost.

 

should be good to go... in my supra days I just ran 3/8 hose from the valve covers to the bottom of the engine. not the most eco friendly way but worked wonders.

 

LOL...I like the way you think.
