How often should LIM gaskets be done? Did I mess UP?
I have a 1999 Buick Le Sabre (98000 miles) that had a hydrostatic lock when the UIM blew thru by the EGR weakened area, after my wife parked it at a shopping mall recently. My mechanic (who I think is great) replaced the UIM with the Dorman kit and put in new plugs and PCV valve. He did not go down further and replace the LIM gaskets. He said he usually doesn't go down to the LIM gaskets unless we were losing coolant before. My question is do the factory LIM gaskets ever go for 200,000+ miles. I hope to drive this car another 100,000 miles and I am wondering if I should have insisted on him doing the LIM gaskets.
