PCV Valve Swap
Where is the PCV Valve located on a 98 Trans Am. Heard that the 98 LS1's have a different location compared to the 1999 an Up LS1's. Thanks for any info!

passenger side of the intake manifold, right between cylinder 2 & 4. you may have to remove a black "spongy" type cover if its never been replaced. just follow the black hose from the passenger side of the throttle body back towards the rear of the manifold and you'll find it
