How do you replace the valve cover gasket for 1998 cadillac Northstar?

Answer 1

first off you want to remove all the bolts on the covers. Off the top of my head I would say they are 10mm. Then if it has that water pump pulley go get or use the one you have to pull that pulley, and remove the belt. Now take the covers off the rear one can be tricky esp. on the northstar. When you have the covers off take the old crush gasket off, and put some grease in the indented lip of the valve cover. yeah It sounds weird but Ive been doing these covers for a while, and this is the easiest way. The grease will not hurt anything, and all it really does is help the valve cover gasket stick in that crack when you flip it to put it on. (IMPORTANT) Only grease the top of the gasket that goes into the valve cover!!!!DON"T USE EXCESS. ounce you have greased, and installed the gasket into the valve cover flip the cover over and slide over valves, and over pulley shaft. set it down square. This will ensure that the gasket doesn't fall out, and it will seat properly. reinstall water pump pulley, and belt. Repeat same on rear one if front went OK don't worry their is no pulley on the rear cover. I hope this helped anyone that has needed a how to, and good luck. Kevin
