I use an AC Delco (it was on the car when I bought it) FV 167 or something like that. Fram makes an FV 167 with a metal base and plastic elbow. No wistle like the plastic ones.

Dave,

Yes, JB Weld is great for that use.
What kind of vacuum are you seeing now?

The Spectre cap with built in PCV I am using is similar to the GM all metal PCV. No noise or anything to wear out especially when using synthetic oil.

Well,I am enlarging the hole a little bit at a time right now , if I give the gas a good punch ,it pulls some vacuum. Sometimes when I slowly raise the RPMs it does nothing until 2700 RPM.When I get vacuum, it does not stay at that pressure ,it will drop.(If I get it up to 5" or 10",it will stay there a second and then drop.)It is better than yesterday ,so I will enlarge the hole a little more ,and then test it again.(don't worry I am not going crazy with the drill bit) :D . I think I am through missing with it today ,its a little warm at 100*
Ted, do you know the part # for your PCV valve grommet?

Thanks
Dave

Well, I decided to go ahead and try it once more, and now at 2000 Rpm I get a steady 8" of vacuum. I think that is good ,because I tested the purge canister valve and it opens up at around 5" of vacuum.If I have time tommorrow I am going to hook up both ported vacuum ports on two seperate gauges and see how they look.
Hopefully it will be successful

Dave,

Most excellent work! Glad you gave it a try and weren't afraid to follow through. :D

It should work just as well as mine.
