dodgethis Posted September 27, 2009 Report Posted September 27, 2009 Hey its getting to be that time again. I am going to replace the Spark plugs, Wires, Fuel Filter, Air Filter, and Pvc. Does anyone have pictures of where the PVC valve is on a 3100? I hope to hell i don't have to take off the throttle body just to get at it. '98 Lumina got around 83,000 Quote
1990lumina Posted September 27, 2009 Report Posted September 27, 2009 The PVC valve on the 3100 is on the front valve cover I thought. Quote
RobertISaar Posted September 27, 2009 Report Posted September 27, 2009 exactly where it is on my 3100... takes all of 2 seconds to change(seriously) Quote
AWeb80 Posted September 27, 2009 Report Posted September 27, 2009 if the PCV rattles, don't change it. It's still good. Rapid Fire 8's for plugs Quote
dodgethis Posted September 27, 2009 Author Report Posted September 27, 2009 sorry guys I'm a noob on this, first time changing out the pcv. So i understand it right around this area, but not eactly what is being circled in this area. Take that back, so that is the pcv. Quote
MonteCarloChick Posted September 28, 2009 Report Posted September 28, 2009 use ac delco plugs and wires Quote
RobertISaar Posted September 28, 2009 Report Posted September 28, 2009 use ac delco plugs and wires plugs: definitely wires: not necessarily. i'm running hand-made Taylor Spiro-Pro 8mm wires.... no EMI issues and has less resistance than the stock wires do... Quote
cutty Posted September 28, 2009 Report Posted September 28, 2009 use ac delco plugs and wires i completely agree. Quote
tunerlover3 Posted September 28, 2009 Report Posted September 28, 2009 I use NGK plugs and wires. Love them. Quote
douellette Posted September 28, 2009 Report Posted September 28, 2009 sorry guys I'm a noob on this, first time changing out the pcv. So i understand it right around this area, but not eactly what is being circled in this area. Take that back, so that is the pcv. i have a question, that hose that connects onto the pcv valve, is it supposed to be loose where is plugs into the top of the throttle body? mine is and im wondering if thats the whistling noise i hear when accelerating.

rockfangd Posted September 28, 2009 Report Posted September 28, 2009 not supposed to be loose. pull the throttle bracket from the TB and pull the hose up. It is a T hose, where the hose pushes into the TB goes bad. I have actually used telon tape around the area that goes into the TB and pressed it back in. Also when you put the bracket back on you can put something between the bracket and the T to keep it in the TB Quote
douellette Posted September 28, 2009 Report Posted September 28, 2009 i was thinking about putting silicone around it to seal it? Quote
AWeb80 Posted September 28, 2009 Report Posted September 28, 2009 or cut a piece off of a 3/8" hose, then shave down the diameter a bit and shove it in there. works great Quote
RobertISaar Posted September 28, 2009 Report Posted September 28, 2009 be sure to check out the connection on the rear valce cover as well. its the other half of the PCV system: valve(front) side pushes air from the motor to the airstream, the other(rear) side allows fresh air in form the airstream.

RobertISaar Posted September 28, 2009 Report Posted September 28, 2009 its not that tough on the MC... i don't have to remove anything to pull the whole thing off. maybe a 30 second process to wiggle it out. but either plug it and essentially make the PCV system a very weak vacuum pump, or get is sealed up and have fresh air running through the motor to replace the air that gets drawn out by the suction side.

dodgethis Posted September 28, 2009 Author Report Posted September 28, 2009 How do you guys get it out? I read you turn it counter clock wise, and a spring and gasket comes out. I must be missing something here because isn't a wrench needed to do that? Quote
dodgethis Posted September 29, 2009 Author Report Posted September 29, 2009 Figured it out, pulled it out with hose attached and swapped it with a new one. I had 80,000 miles on the car and its supposed to be changed every 30,000 miles I went ahead and did it anyway. That was easy. Quote

xtremerevolution Posted September 29, 2009 Report Posted September 29, 2009 Man I'm confused here. I've never changed the PCV Valve on my 3800 Series 1. I know where it is, and have seen pictures of it. What is its purpose? What are the consequences of me not changing it after...207k miles? Quote
digitaloutsider Posted September 29, 2009 Report Posted September 29, 2009 It's probably clogged full of shit and not ventilating anything. Quote
