Code 51 ?!

ok. Did the vacuum test on the car. It did nothing, no stall or change in idle. It held vacuum. Took the EGR off. Gasket was destroyed. The valve was covered and gunked up on the outside with oil. The had been a long time valve cover gasket leak. One of the bolts was also soaked in oil when I removed it. Completely cleaned the valve. Retested the vacuum. Pintel moves freely. Took a while to clear all the gunk. Inside was a bit carboned up but not bad. Removed as much as possible. looks good. The thermistor or thermoprobe. connected to it was also oiled up. Cleaned that off. Started cleaning where it bolts onto. Took pix. Looks decent not blocked. FOund the bark test and VSS test, will run those. I think I have an early 16V as I dont have the #50 tube. Got a wire to go very far in with no problem. I have not done the hot engine vacuum test. I ordered a new gasket. . Also the flying saucer thing above the EGR (I assume is the modulator) its tube was just shoved onto the curved hose. Not a great seal, and no clamp. (I also noticed one of the heater hoses was crimped so Im going to cut it and fix it)
