Still waiting to see if decking the heads will stop water from getting inside the engine. someone had already replaced the head gaskets to no avail. If that problem gets solved I'm on to the next one. My mechanic pointed out that the supercharger is slinging oil onto the firewall and under hood area. Looks like from behind the pully. The boost gauge shows that it's still making boost. It would seem to me that replacing the neck portion would be the easiest and cheapest way to fix the problem but being a 05 model, there seems to be a limited supply of shops that sell just the neck (none that I could find). can anyone suggest a solution? I really don't want the car down for 2 or 3 weeks while the existing SC is being rebuilt. I checked the parts page here but didn't see a good used one for sale. If anyone knows a good mechanic or shop in or around ST. Tammany parish please pass on the name and contact info.
