3.8L mild refresh. Where to stop. Am I missing anything? March 30, 2013, 12:02:42 AM As I posted in the racing forum, the head gasket in my '87 3.8L Thunderbird took it's ball and went home during the first event of the day - skidpad. :(At a minimum, the head gaskets need replacing. Engine has 262k miles on it. Timing cover also needs a reseal -leaking coolant. While I'm at it, might as well throw in a oil pump repair kit. Valve seals? Anything else I should probably do while I'm in there?
