Intake Leak???

[backfocus]

I recently changed my valve cover gaskets and when putting the intake back on I put on a new Trickflow intake spacer and gaskets for my GT-40 intake, since I had a hard time getting the gaskets off the one I had on it. I used new gaskets that came with the spacer and plug everything back in. Went to start it up and it lopes bad, is hard to keep running until it warms up. When it does warm up the car idles at 1200 RPM, but seem it sound find but does lack power.

Does anyone have any ideas or had problems with getting the GT 40 intake to seal properly, as this is not the first time I have had this problem. I put 22 ftp on the bolts as the recommended was 18-24, I have tried to listen for a vacum leak but can't find any. I read about a starter fluid technique that I will try tomorrow. Any other help would be helpfull.

Thaks

Next time, get some 7/16" (should be intake bolt size) bolts a few inches long and chop the heads off, slit the ends w/ dremel or saw or something and use them as dowels to line up the intake...it won't move around and should seal fine. Sounds like you're talking about the upper intake, though, which I can't see how it would leak if you torqued properly and put gaskets on.

Have you thought that, for some reason, maybe that spacer is your problem? Just an idea as it's the variable here. Make sure your vac. lines are plugged up in the proper place...I know you said they're all plugged up. That does sound like a vac leak though. I guess try your starting fluid thing and see if you can find a vac leak, if not

Use a vacuum gauge to see if the vacuum is low (under 15" at 650-725 RPM) before you start looking for vacuum leaks. I recommend that you use motor oil in a squirt can (no chance of flash fire) to locate leaks if the vacuum is below 15". The motor will speed up and the oil will dissapear if you squirt it on a leaking gasket.
