Over the past week I have had to remove a low mileage 94 engine from a donor car, as my ported/reworked heads were not going to make it here in time for the shootout, and install it in my 94 5 speed. I have added the following components over the past week and when I start it I have the leak explained below.
-80maf
-60lb injectors
-aeromotive fuel pressure regulator
-marshall fuel pressure gauge
-rebuilt transmission
-new slave cylinder
-new aluminium flywheel
-centerforce dual friction clutch
-ported manifolds with scp exhaust
-egr delete
-stock throttle body ( I will have an 85mm but won't have it till I get to dayton)
-mpx blower with partially coated rotors( my early blowers all need a rebuilt and the coated rotors were not recommended for the stock long block)
25% overdrive kit with wider belt and heavy duty tentioner springs
-aluminium drive shaft
-255lph fuel pump
-sct chip
Now the problem like I stated in the title is I have a major vacuum leak. I believe it is from the throttle body. I can start the car and as long as I keep my foot on the gas the car runs great but there is a sucking noise. I have checked all the connections and they are all secure so the only thing I can think of it the throttle body as there is very little meat when it bolts to the inlet plenum on the MPX. any suggestions as I would like to take the car for a spin to test out the tranny and get it to operating temps to check for leaks and problems under minimal boost. I am not able to run the car long enough to look at the problem, hopefully I can get a second set of eyes tomorrow but if anybody could confirm that a sucking noise would be indictive of a leaky t-body to the inlet plenum that would save me some time.
Thanks,
John
