Default 97 emissions and pvc delete help.

I need help finding all the emissions and Pvc crap to delete, I deleted the hose running from intake to valve cover, and the hoses running from header to header to the evap system. Now just trying to figure out how to delete the evap and the rest of the crap. I noticed there's a hose going from the header on.passenger side to the intake any help would be nice

For the back of.the intake you will need EGR block off plates. Possibly have the egr and a.I.r. system deleted from the tune.

keep the PCV it is actually beneficial to a motor.


everything else is pressty straight forward to remove, and figure out a way to block the holes they leave behind.


also, don't forforget to tune the car once it's all said and done, or a CEL and limp mode will most likely result.

why is a pvc benificial? I don't see a reason why it would be, it pulled a po410 code earlier and didn't go into a limp mode. I've already capped the holes where the exhaust flow runs into both headers and into the emissions pump, just trying to figure a way to block that pump that goes into the front of the engine so I no longer have it in my engine bay.

I just don't see sucking used oil and other crap into my intake therefore into my heads, gunking up my engine is benifical. Just like the egr I don't see blowing hot exhuast gas into my intake healthy for a engine. I would rather delete these crap now and not deal with it in the future.

You need to keep the (PCV)positive crankcase ventilation in place you can put a filter between it and the nipple on the bottom front side of the intake....
