Captain Ficho Posted May 12, 2008 Report Posted May 12, 2008 Today I pulled my PCV Valve and put my new one in. It was an easy job, but then the inner historian in me came out. So I took my old one out and it looked pretty battered. I got no maintenance records with the car so I was curious vaguely how old it is. I looked at it closely and it has the name "AC Rochester" imprinted in it. I did a little googling and AC Rochester merged with AC Remy in 1994 and they formed Delco Systems... does that mean this is a pre-1994 PCV valve? Could it even be the original one from 92? Does that explain why I am get 18mpg? Quote

Captain Ficho Posted May 12, 2008 Author Report Posted May 12, 2008 ... soooo... vintage PCV Valve circa 1992 for sale... mostly functional, I'll take bids starting at $800, anyone? Perfect for anyone who wants wants authentic General Motors goodness! Quote
GnatGoSplat Posted May 13, 2008 Report Posted May 13, 2008 My 89 still has its original PCV. I guess I could have changed it back in '99 when I had the plenum off, but I was always under the impression if the ball still rattles, the PCV is okay. I swear I read that someplace. Quote
per0781 Posted May 13, 2008 Report Posted May 13, 2008 if the ball still rattles, the PCV is okay. correct sir Quote

Wow - are you telling me that for one of the few instances that the LQ1 PCV valve is easier to change than on the pushrod engines?!? Then of course, there's changing the plug wires AND routing them properly in the clips (and the zip tube covers) like the factory did - I found it easier to remove the cooling fans first to gain more room for my hands.

An LQ1 PCV is a thousand times easier than doing one on an LH0...lol Quote
Captain Ficho Posted May 14, 2008 Author Report Posted May 14, 2008 Yep, it even took me a minute or two and I'm still learning about the LQ1... and by that I mean I'm a total noob. Quote
kwk39018 Posted May 15, 2008 Report Posted May 15, 2008 Yep did it a year ago on my 93 pushrod when i did the tune up, never will do it again! Quote
