Yesterday we performed the 1st ever maint. on a car..usually we just have our cars taken to the shop whenever anything is need done but this is different..We bought our 75 imperial off of ebay and we got lucky because the guy we bought it from told us everything about the car..even down to the fact it needed new valve cover gaskets in the near future..so yesterday we took on the job..4 hrs later..LOL..we had finished and to our surprise no leaks, also there was no "crud" under the valve covers that leads us to believe the he really did take care of this car.. Next week..draining and flushing the cooling system..Bill & Elaine --- [This E-mail scanned for viruses by tigerpaw.com]
