Bruce Amacker Posted June 22, 2010 Share Posted June 22, 2010 Yes, on an F-model. Why are you changing it? I usually suggest them in sets..... Quote Link to comment Share on other sites More sharing options...

joshbuys Posted June 25, 2010 Share Posted June 25, 2010 Make sure you drop a dime in the bottom of the cup before you start running the tap in - it will keep the shavings out of the cylinder! Quote Link to comment Share on other sites More sharing options...
Aaron Posted June 26, 2010 Share Posted June 26, 2010 If you are doing it warranty, make sure you have a head gasket and bolt set to return, they are gonna ask for it since WSM procedure says to take the head off to replace the cups.
