PP oil psi high after catch can

[fishin911]

Hi everyone
I installed a upr dual catch can and post installing my oil psi have been over 80 psi cold and drops to 60 psi once engine warms up. 1st and 2nd gear will pin the oil to 100psi @ 5k rpm with makes me let off the gas or shift. 3gear and up are fine. Prior to catch can oil psi where always within normal limits.
Any ideas why the drastic jump?
Thanks

Well it has nothing to do with the catch cans. My oil pressure is 80 or a little higher at cold idle, I wouldn't know what it is a 5k rpm cold because I would never rev the engine that high until the oil temp is in the green range. Did you change the oil when you did the catch can?

After my engine is warm and I'm driving the oil psi goes from ~60 psi up to ~100psi driving on 1 and 2 gear @ around 5k. Not hat I'm revving my engine cold to 5k. For this reason, I've stay off trying to push the car 0-60 post warm engine.
Thanks for you reply

Mines 80 psi until warmed up also. Seems there isn't anything wrong

You should ensure that both check valve have the arrows facing away from the catch can and that both lines with check valve are on the side ports and not the top of the can.

If you don't have it all together correctly you are blocking your PCV system.

I just pop the hood and triple check my lines. They seemed to be installed correctly, so I took the clean line ( throttle ) and check valve line and both do not have arrows indicating any direction. I blow through them to make sure the check valve on both lines are pushing towards catch can which they are. Also, can been in for a couple hundred miles and no oil inside? Don't know what else to do??? Thinking of passing by upr and see if someone would be kind enough to take a quick look for me.

They should have arrows on the valves unless UPR changed the design recently. No oil in the can is a possible indication that its not on right. I would go by UPR if you are having trouble figuring it out.

Also not sure what you mean by blowing through the lines. Air should only be able to go away from the can on the clean lines.

Try putting your original lines back on and test again.
You should get the same results as you reported in your original post.

I Literately took the lines to my lips and blew. Clean line is on correctly allowing me to blow towards the catch can and WOT vacuum line only allows me to blow air towards the catch can too.

You shouldn't be able to blow towards the can... Your lines are on backwards. Think about it. The reason for the check valve is so when the manifold is pressurized the can doesn't get pressurized too. Thus the valve should be closed if air is coming from the manifold. The way you have your lines right now means your PCV system is literally blocked. There are arrows on the check valves, I think you are just missing them, they are engraved on one side.

LOL you should be sucking not blowing it draws through the catch can.

Don't feel bad. You aren't the first person that's done it. UPR's can is a nice product, but the instructions are seriously lacking.
