Q:What are the torque specs for a 1994 Mazda 929 valve cover?
you do not torque valve covers down, buy a new gasket , I would get a good quality rubber one and some blue rtv sealer, clean any crap off the valve cover no glue no bits of gasket nothing, same thing on the head surface, glue the gasket on the valve cover, let it set, then carefully put it on, start with the bolts in the middle and work out finger tight all of them, then just snug the bolts down, dont crush the gasket, you can also use a light duty locktite to hold them in place, and often times old valve covers are warped, it is too your advantage to make sure its as flat as you can get it, or spend a few bucks a buy a new one. your choice, but snug the nuts down good with out crushing and bending the thin sheet metal of the valve cover.
Q:Are all vacuum EGR valve the same?
Did you get that EGR valve from Cadillac dealership?? A lot of those aftermarket parts DO NOT LIKE Cadillac's!!!!!!!!!! I run into that all the time nor will we use any aftermarket parts due to the problems we have with them. Make sure that switch is working that controls the EGR valve. I have seen those fail also. You need access to a serive manual so you can command that switch on off check with a test light a vacuum gauge to make sure you are getting vacuum to that EGR Valve. Also, make sure that the ports are not clogged up with carbon, even check the pipe inside the throttle body opening, they should be clean inside those tubes !!!!!!!!!
